Community Nursing - Essay Example On the other hand, community health nursing is majorly inclined into three categories. These are referred to as tools of community nursing health practice which include community organizing, epidemiology and health education.Epidiomology deals with the determinants and distribution of injuries and decisions in human population. Community health nursing majorly study populations on the basis on age group with main reference to health problems related to each group. Some of the groups are infants, mothers (below twelve months, children with ages one to fourteen, young adults and many others. Health issue depending on age bracket may include; maternal health which encompasses prenatal care, family planning and abortion (McEwen & Willis, 2007). There are a number of partnerships involved in both public health nursing and community health nursing. They include government health agencies, quasi-governmental organizations dealing with health and lastly nongovernmental health agencies. For instance, Centre for Disease Control (CDC) partnering with Kenyan government in Africa to tackle HIV scourage.Government may fund transportation as CDC funds antroritoviral drugs distribution among the poor populations to curb faster death rates among HIV patients. Summarily, Watson’s theory of transpersonal care consists of the aspects of kindness, love and equanimity in relation to intentional caring. It advocates for being present authentically and cultivation f transpersonal self which surpasses the ego self. Both community health nursing tools and public health objectives and intentions ultimately compliment Watson’s theory since the aspect of care and self giving is a prerequisite of the two

Verification vs Validation Essay Example for Free

Verification vs Validation Essay Verification ensures that the system (software, hardware, documentation, and personnel) complies with an organization’s standards and processes, relying on review of non-executable methods. Validation physically ensures that the system operates according to plan by executing the system functions through a series of tests that can be observed and evaluated. Verification answers the question, â€Å"Did we build the right system?† while validation addresses, â€Å"Did we build the system right?† Verification requires several types of reviews, including requirements reviews, design reviews, code walkthroughs, code inspections, and test reviews. The system user should be involved in these reviews to find defects before they are built into the system. In the case of purchased systems, user input is needed to assure that the supplier makes the appropriate tests to eliminate defects. Validation is accomplished simply by executing a real-life function. This includes unit testing, integration testing, system testing and user acceptance testing. In this rigorous testing is conducted to validate if the system meets the functional requirement. The three most important skills that a system analysis should have are the same for any company. They should first and foremost have people skills. You have to be able to work with a variety of people and be able to work in teams. You should be an assertive person also. A good systems analysis should be able to take initiative and do things without being told. Also this person should have good reasoning and problem solving skills. These are all things that should be within the person naturally along with the actual computer skills necessary to analyze systems for a client. -are ability to work well with others, -good communication skills, -the ability to ask the right questions Bidder Responsibility Determination: To be determined responsible, a bidder must be successfully evaluated against the 7 following criteria: 1. Financial Resources. The bidder must have adequate financial resources to perform the contract, or the ability to obtain them (see FAR 9.104-3(a)—Ability to Obtain Resources). 2. Performance Schedule. The bidder must be able to comply with the performance schedule, required or proposed delivery, taking into consideration all existing commercial and governmental business commitments. 3. Performance Record. The bidder must have have a satisfactory performance history, if any (see FAR 9.104-3(b)—Satisfactory Performance Record and Experience Certificate). Nevertheless, a prospective contractor shall not be determined responsible or non-responsible solely because of a lack of relevant performance history, except when specified in a standard for special acquisitions. 4. Integrity and Ethics. The bidder must have a satisfactory record of integrity and business ethics including satisfactory compliance with laws related to taxes, labor and employment, environment, antitrust, and consumer protection (see FAR 9.406-2—Causes for debarment and FAR 9.407-2—Causes for suspension). 5. Organization and Skills. The bidder must have the necessary organization and skills, experience, accounting and operational controls, and technical skills, or the ability to obtain them (see FAR 9.104-3(a)—Ability to Obtain Resources). 6. Equipment and Facilities. The bidder must have the necessary technical equipment and facilities for production or construction, or ability to obtain them (see FAR 9.104-3(a)—Ability to Obtain Resources); and 7. Other Qualification. The bidder must be otherwise qualified and eligible to receive an award under applicable laws and regulations. Systems Engineering V Model The system life cycle The system life cycle has seven phases: (1) discovering system requirements, (2) investigating alternatives, (3) full-scale engineering design, (4) implementation, (5) integration and test, (6) operation, maintenance and evaluation and (7) retirement, disposal and replacement. However, the system life cycle is different for different industries, products and customers. State the problem The problem statement starts with a description of the top-level function that the system must perform or the deficiency that must be ameliorated. It includes system requirements stated in terms of what must be done, not how to do it. It might be composed in words or as a model. Inputs come from end users, operators, bill payers, owners, regulatory agencies, victims, sponsors, Marketing, Manufacturing, etc. These are called stakeholders. In a modern business environment, the problem statement starts with a reason for change followed by vision and mission statements for the company. Understand customer needs Customers seldom know what they want or need. Systems Engineers must enter the customers environment and find out how the customer will use the system. Talking to your customers customer and your suppliers supplier can be very useful. Frameworks, such as the Zachman framework or the DoDAF, are useful for seeing how the system fits into the customers enterprise. Discover system requirements There are two types of system requirements: mandatory and tradeoff Mandatory requirements insure that the system satisfies the customers operational need, and must be passed or failed, there is no middle ground. The tradeoff requirements are evaluated to determine the preferred designs, and should state conditions that would make the customer happier. Verify and validate requirements Investigate alternatives Alternative designs are evaluated based on performance, cost, schedule and risk criteria. This analysis should be redone whenever more data are available. Define quantitative measures Performance and cost criteria show how well the system satisfies its requirements, e.g., In this test the car accelerated from 0 to 60 in 6.5 seconds. Technical performance measures (TPMs) are made during the design and manufacturing process to evaluate the likelihood of satisfying the system requirements. Model the system Models will be developed for most alternative designs. Many types of system models are used, such as block diagrams, functional flow diagrams, object-oriented models, computer simulations. Design the system The overall system must be partitioned into subsystems, subsystems must be partitioned into assemblies, etc. Reusability should be considered in creating subsystems. For new designs, subsystems should be created so that they can be reused in future products. For redesign, subsystems should be created to maximize the use of existing, particularly commercially available, products. Systems engineers must also decide whether to make or buy the subsystems, first trying to use commercially available subsystems. If nothing satisfies all the requirements, then modification of an existing subsystem should be considered. If this proves unsatisfactory, then some subsystems will have to be designed in-house. Flexibility is more important than optimality. Hardware, software and bioware must be considered. Bioware (or wetware) means humans and other biological organisms that are a part of the system. For example, in designing a race track the horses or dogs are a part of the bioware. Create sequence diagrams Define system architecture Some choices that have to be made: (1) object-oriented design, structured analysis, or functional decomposition, (2) distributed or centralized computing, (3) commercial off the shelf (CoTS) or custom designed. Functional analysis Systems engineers do functional analysis on new systems (1) to map functions to physical components, thereby ensuring that each function has an acknowledged owner, (2) to map functions to system requirements, and (3) to ensure that all necessary tasks are listed and that no unnecessary tasks are requested. This list becomes the basis for the work breakdown structure. A work breakdown structure (WBS) breaks a project into smaller, more manageable components. Sensitivity analyses Sensitivity analyses can be used to point out the requirements and parameters that have the biggest effects on cost, schedule and performance. They are used to help allocate resources. Assess and manage risk There are two types of risk: risk of project failure (due to cost overruns, time overruns or failure to meet performance specifications) and risk of harm (usually called personnel safety). A failure modes and effects analysis and risk mitigation must be performed. Project risk can be reduced by supervising quality and timely delivery of purchased items. Reliability analysis Major failure modes must be analyzed for probability of occurrence and severity of occurrence. Integrate system components Integration means bringing things together so they work as a whole. System integration means bringing subsystems together to produce the desired result and ensure that the subsystems will interact to satisfy the customers needs. End users and engineers need to be taught to use the system with courses, manuals and training on the prototypes. Design and manage interfaces Interfaces between subsystems and interfaces between the main system and the external world must be designed. Well-designed subsystems send finished products to other subsystems. When designing subsystems and their interfaces be sure to consider reuse. Launch the system Launching the system means doing what the system was intended to do, e.g. running the system and producing outputs. Configuration management Configuration management (also called modification management) ensures that any changes in requirements, design or implementation are controlled, carefully identified, and accurately recorded. All stakeholders should have an opportunity to comment on proposed changes. Decisions to adopt a change must be captured in a baseline database. Baselines can only be changed at specified points in the life cycle. The phrase requirements tracking is now being used for an important subset of configuration management. Project management Project management is the planning, organizing, directing, and controlling of company resources to meet specific goals and objectives within time, within cost and at the desired performance level. Project management creates the work breakdown structure, which provides structure for guiding team assignments and cost and tracking control. Documentation All of these Systems Engineering activities must be documented in a common repository, often called the Engineering Notebook. The stored information should be location, platform, and display independent: which means any person on any computer using any tool should be able to operate on the fundamental data. Assumptions, results of tradeoff studies and the reasons for making critical decisions should be recorded. These documents should be alive and growing. For example, at the end of the system life cycle there should be an accurate model of the existing system to help with retirement. Lead teams Complex systems cannot be designed by one person. Consequently engineers work on Integrated Product Development Teams (IPDTs). These teams are interdisciplinary with members from Business, Engineering, Manufacturing, Testing, etc. IPDTs are often led by Systems Engineers. Assess Performance During the operation and maintenance phase of the system life cycle the performance of the system must be measured. Initially these measurements will be used to verify that the system is in compliance with its requirements. Later they will be used to detect deterioration and initiate maintenance. Prescribe tests Early in the system life cycle Systems Engineering should describe the tests that will be used to prove compliance of the final system with its requirements. However, most testing should be performed by built-in self-test equipment. These self-tests should be used for initial testing, post-installation testing, power-up diagnostics, field service and depot repair. The recipient of each test result and the action to be taken if the system passes or fails each test must be stated. Conduct reviews Systems Engineering should ensure that the appropriate reviews are conducted and documented. The following set is common: Mission Concept Review, System Requirements Review (SRR), System Definition Review, Preliminary Design Review (PDR), Critical Design Review (CDR), Production Readiness Review (PRR), and System Test. Full-scale engineering design begins after the Preliminary Design Review. Manufacturing begins after the Critical Design Review. Total system test The system that is finally built must be tested to see (1) that it satisfies the mandatory requirements, and (2) how well it satisfies the tradeoff requirements. Re-evaluation Re-evaluation is arguably the most important task of Systems Engineering. For centuries engineers have used feedback to control systems and improve performance. It is one of the most fundamental engineering tools. Re-evaluation means observing outputs and using this information to modify the system inputs, the product or the process. Re-evaluation should be a continual process with many parallel loops. Everyone should continually re-evaluate the system looking for ways to improve quality. Tools used in this process include basic systems engineering, and the quality engineering techniques presented by, for example, Deming and Taguchi. Deming (1982); Bicknell and Bicknell (1994); Latzko and Saunders (1995). Near the end of the project, engineers should write a Lessons Learned document. These lessons learned should not be edited by management, because management could trivialize what they do not understand or omit management mistakes. Categories of Systems Engineers Many companies divide their Systems Engineers into three categories according to their major workflows: requirements definition, architectural design and testing and verification. Creating Systems Engineers The traditional method of creating Systems Engineers was to select well-organized engineers with lots of common sense and let them acquire 30 years of diverse engineering experience. But recently these traditional Systems Engineers have written books and standards that explain what they do and how they do it. So now that the tools, concepts and procedures have been formalized, in four years of undergraduate education we can teach Systems Engineers who will have performance levels 50% that of traditional Senior Systems Engineers. Ten years of systems engineering experience will improve performance to 80% and another ten years will increase it to 100%.

Is Global Warming A Natural Phenomenon Environmental Sciences Essay

Is Global Warming A Natural Phenomenon Environmental Sciences Essay Is the temperature rising or is it just us? One of the most highly debated topics in todays society is global warming. Are we humans destroying the Earth we live on without knowing its devastating effects or is it the inevitable? Some say that the burden we put on the Earth is causing a rise in the greenhouse gases and carbon dioxide emissions. Others argue that global warming is naturally occurring or it truly does not exist. How can something not exist when all the evidence points to it? Recent studies have shown that an increase in carbon dioxide concentrations and other greenhouse gases caused by human activity is warming up the planet. Researchers and scientists have been studying the climate changes from the late 1950s up till today and no findings have pointed towards anything but humans causing this disaster. A way to define global warming is through the Greenhouse Effect. The process starts with the solar radiation to the Earths surface which absorbs the rays and heats up the surface. Since the Earth does not absorb all the radiation from the sun, it is simply reflected off its surface back into space. It is here where the problem occurs. When the rays reflect off the Earths surface they are not leaving the lower atmosphere due to greenhouse gases and other emissions. This causes the infrared rays to stay inside the Earths atmosphere and cause the temperature to rise. When an infrared ray strikes a molecule like carbon dioxide or a greenhouse gas it causes the bond to vibrate and it gains kinetic energy. Now that this molecule has more kinetic energy, it can transfer it to one of the two major gases in the atmosphere, oxygen and nitrogen. When the gases receive this extra energy it causes a general heating of the atmosphere. The diagram on the next page depicts how the process works. FIGURE 1: The Greenhouse Effect In the late 1950s, researchers carefully studied the amounts of carbon dioxide and other greenhouse gases in the atmosphere. At that time, scientists agreed that the amount of carbon dioxide in parts per million was 315. Now today in 2008, that parts per million of carbon dioxide in the atmosphere is about 385. What caused this increase of carbon dioxide and other greenhouse gases? Human activities such as fossil fuel burning, cement, production, and deforestation caused this increase of carbon dioxide in the atmosphere. How do we know that these numbers are accurate? Scientists can measure the amount of greenhouse gases in from bubbles of air that were naturally preserved in ice in Antarctica and Greenland dating back to more than 650,000 years ago. The amount of carbon dioxide concentrations in the last 400,000 years had a cyclical pattern. The amounts would rise to just about 300 parts per million and decrease to about 200 parts per million in a 100,000 year time frame then rise a gain. Just recently the parts per million have skyrocketed. Today that number of parts per million is still increasing and is almost at 400. Why is it now that this number has increased rapidly? The population today of the entire world is booming to more than six billion people. In the United States the population is currently more than 300,000,000. No more than twenty years ago the population in 1990 was around 249,000,000. In that little of time the population grew more than 50,000,000. Now think of all the countries in the world. The population is putting the Earth at risk and this is why the amount of carbon dioxide and other greenhouse gases are increasing. Another argument that proves the global is heating up is evidence from the I.P.C.C. (Intergovernmental Panel on Climate Change) Last year the I.P.C.C. published a six year long study on the science of global warming and picked up the Nobel Peace Prize for its efforts. (Monastersky) The I.P.C.C. has gathered information from nine different global using land stations. Each of these land stations cover large regions and record the surface temperature. Each land station from around 1950 has shown an increase of land temperature from 0Â °C to 0.4Â °C. Overall, in the last century the Earths surface temperature has increased by 1.3Â °F. (Schneider) Even though this is the tiniest increase it still effects how the Earth emits radiation. The hotter the temperature of the Earths surface gets the more it needs to emit the radiation. This causes a problem because the greenhouse gases and other molecules are reflecting the rays back to the Earth and are staying in the atmosphere, once again c ausing a rise in temperature. Figure 2: Global Temperature Time Series The figure above shows the Earths surface temperature in nine different locations Now that the evidence proves the Earths surface is heating up and the atmosphere is being ruined by carbon dioxide emissions, how can we prove that humans are doing this? In a recent study from Purdue University, they named the U.S.A.s top cities for carbon dioxide emissions. A few of the top cities were Los Angeles, Chicago, Pennsylvania Carbon County, and Indiana County. From the image below, the key shows that levels with red or brown areas are top producers of carbon dioxide emissions. What makes these areas red? Studies show that the reason is the burning of fossil fuels. Examples of fossil fuels are coal, oil, and natural gas. These three sources of energy play a huge role in the world because they are used everyday in excessive amounts. When fossil fuels are burned or used they produce carbon dioxide emissions. Figure 3: Top Carbon Dioxide Emitters in the United States The figure above shows areas in the United States that emit carbon dioxide. The areas that emit the most are shown in red or brown. The Earth can only absorb so much of these emissions that eventually it cannot anymore and it causes excessive amounts in the atmosphere. How do humans burn fossil fuels? Everyday activities like driving a car, using an aerosol can, working at a factory, and working at power plants. Each of these burn fossil fuels and destroys the atmosphere. Think of how many cars are on the road right now driving and burning gas. The amount of the carbon emissions coming form vehicles is overwhelming and is causing this change in climate. Finally, car manufacturers are realizing that this is becoming a huge epidemic and they are now producing hybrid vehicles and more gas efficient vehicles. Factories and power plants produce a ridiculous amount of pollution each day that is doing irreversible damage to the Earth. An argument against global warming is that it is naturally occurring. This is a possibility because no expert or researcher has completely understood the Earths cycle of ice ages and warm periods. There is a slight possibly that this could be just one of the Earths warm periods. Evidence proves otherwise. According to researchers it is nearly impossible to explain this climate change without external force. This means that something other than a natural cause is a factor in the climate change. Another counterargument against global warming is that the rising levels of carbon dioxide in the atmosphere are from the ocean. When researchers studied the oceans, they saw that levels of the carbon dioxide in the ocean were high like the amount in the atmosphere. If the ocean was emitting carbon dioxide then the levels in the ocean would be lower. With all the evidence, it is clear that humans are contributing to global warming. This has only become a problem now because our economy is going as well as our population. Fifty years ago, the economy was not even close to being as advanced and big as it is today. Our population is still growing and we are only taking baby steps to fix this problem. If harsh action does not take place soon we will destroy the Earth forever. The warming of the oceans and atmosphere could trigger irreversible environmental changes in coming decades. (Monastersky)

Red Serpent - Fiction :: Papers

Red Serpent - Fiction Something stirred in the gloomy shadows that seemed to lurk everywhere in this town. She reached into her jacket and withdrew a small black pistol. It fitted snugly into her hand and with a feeling of safety, she loaded it. With four quick strides she reached the end of the alley where she looked round and returned the pistol to its holster. The wind howled round the corner, almost knocking her to the floor. In the process she stooped low enough for the light from a nearby streetlight to shine onto her bare left shoulder. Etched into the back of it was a tattoo of an elaborate red serpent. After bracing herself for what was to come, she stepped out into the street. Two shots echoed down the alley and struck the attacker flat in the back of the head. She had dark brown hair, parted only a little enough to let the deadly bullet part her from her existence. The victim did not falter and she did not show any pain from the metal projectile that had shattered her fragile existence. Instead she stood lifeless as though hanging in the balance between what her life had been before and what was inevitably to come. Paul Harris was about six foot three with short cut, blonde hair and eyes that his friends informed him could pierce through anyone he interrogated, something that came in handy in his line of work. "They sure make these simulations realistic, don't they?" "They sure do. I still can't believe they're not real myself and I'm supposed to be running the place!" said Willis, the Armourer. "The director wants to see you right away" Harris followed Willis towards the director's office. "See you next week," said Harris before striding off down the corridor. "I'll be waiting," muttered Willis under his breath as he set off back towards the door that he had come from. "Sit down," ordered the Director. The Director's office was expensively, but sparsely furnished. The

The Importance Of Critical Thinking Skills Education Essay

Moore viewed critical thought accomplishment is highlighted as an indispensable foundation to bring forth womb-to-tomb scholars for Twentieth Century acquisition. This chapter will discourse on the importance of critical thought accomplishments, critical thought and employability, execution and challenges of learning critical thought in Malaysia every bit good as theory and schemes to learn critical thought. This chapter will besides lucubrate further on the interconnectedness between engineering, linguistic communication and higher order believing accomplishments, argumentative cognition acquisition and eventually, depict the Toulmin ‘s Model.The importance of critical thought accomplishmentsHarmonizing to Edmonds et Al. ( 2005 ) , critical thought has many definitions over the past old ages ; nevertheless, it can be concluded as an active mental procedure that includes mental accomplishments such as conceptualizing, analysing, using, synthesising and measuring information in order to emerge with an reply or decision. Everyone needs to hold an ability to work out jobs throughout their lives. Therefore, many educational experts have stressed on the importance of transfusing higher order believing accomplishments in one ‘s instruction as it helps pupils to analyze the state of affairs, learn the undertakings better before emerge with solution both in academic and non-academic fortunes ( Chance, 1986 ; Tama, 1989 ; Ennis, 1992 ; Elder & A ; Paul, 2001, ) . This is because believing and larning are interrelated as one has to independently believe and seek solutions to a job or state of affairs in order to derive cognition. Research findings indicate that critical thought accomplishment can be taught and improved in everyone and this accomplishment should be integrated in the course of study at all degrees ( Grant, 1988 ; Paul et al. , 1989 ; White, Burke, 1992 ; McKendree et al. , 2002 ) . Sternberg ( 2003 ) stated that one of the ends of instruction is to bring forth womb-to-tomb scholars who posses the qualities of intelligent, critical minds which is believed to be able to believe independently, analytically and critically to see a better calling accomplishment in order to derive personal satisfaction and hopefully, contribute to national accomplishment to develop his state. This is because larning is an on-going procedure that may happen in academic and non-academic fortunes. Without critical thought accomplishments, Sternberg ( 2003 ) further elaborated that schools and universities will merely bring forth extremely fleeceable pupils and alumnuss who may be knowing, but deficiency of the accomplishments to believe critically and analytically over a state of affairs. This is because they are merely passively having information exhibited by the political leaders as information can be easy transmitted by the media via assorted signifier in this epoch of rapid develop ment of Information Technology ( IT ) . Without ability to believe critically, they besides would subsequently confront some jobs when they become employees as they need to pass on well-reasoned thoughts and would non be able to actively lend to educational treatments due to hapless communicating accomplishments and deficiency of analytical logical thinking to a state of affairs at manus ( Education Reform in Malaysia Report, 2012 ) .Critical thought and employabilityPaul ( 1995 ) claimed that critical thought is a critical foundation to the accommodations needed for mundane societal, personal and professional demands of the twenty-first Century. It is further supported by Elder ( 2000 ) who claims that it is of import to learn higher order believing accomplishments to pupils in schools and universities as today ‘s society has become more complex due to rapid alteration in engineering. The society demand to be able to analyze the huge information that can be gathered effortles sly via online and merely choice necessities from it ( Chartrand, 2009 ) . Henwood ( 2007 ) claimed this state of affairs besides applied in twenty-four hours to twenty-four hours existent life state of affairss. Hence, he farther stated that pupils who are ill-equipped with critical thought accomplishments will non be able to get by with the challenges and demands of current occupation market. This is because higher order believing accomplishment is believed as one of the most indispensable soft accomplishments for future employability of the new coevalss. â€Å" aˆÂ ¦workplace literacy in the following millenary will be synonymous with job resolution. † ( Mariam Jean Dreher, 2000 ) Mariam Jean Dreher ( 2000 ) predicts that the hereafter will name for a life style ; both in instruction and calling field ; of independent job convergent thinkers that requires multiliteracies which involves higher order believing accomplishments. In Malaysia, the research findings claim that critical thought accomplishment is extremely valued in the workplace today ( DETYA, 2000 ; Chartrand, 2009 ) . Norshima ( 2011 ) studies that Malaysia produces 60, 000 alumnuss yearly in which at least 30 per centum of these alumnuss are unemployed every twelvemonth as they are lacked of these powerful accomplishments. This is farther supported by Gurvinder Kaur and Sharan Kaur ( 2009 ) who claimed that in Malaysia, six out of 10 university alumnuss take every bit much as six months to be employed due to miss of critical thought accomplishments and hapless communicating accomplishments. Fong ( 2004 ) and Vijan ( 2007 ) findings stated that the grounds that Malayan alumnuss are unemployed because they are non able to affect their possible hereafter employers during interview due to hapless presentation and communicating accomplishments particularly if it is done in English. Besides, Malayan instruction system is said to be excessively exam-oriented and therefore, the alumnuss could non lend every bit much once they start working as they are merely theoretically competent but non equipped with sufficient practical exposure ( Henwood, 2007 ) . This is farther supported by Rosnani ( 2009 ) and Education Reform in Malaysia Report ( 2012 ) findings which stated that employers in Malaysia, specifically in concern sector, complain about the low quality of most alumnuss from Malaysia are lacking in footings of critical thought accomplishments which in return affect the quality of their work.Execution of critical thought in MalayaDue to the uprising employees ‘ concern over the lacking of this powerful soft accomplishment amongst newly alumnuss employers globally, course of study of educational system has been bit by bit revamped over the old ages. This state of affairs is particularly true in most prima or developing states like the United States, England and Singapore ( Nagappan, 2001 ; Willingham, 2007 ) . The demand to instill critical thought accomplishments into Malayan instruction system is therefore undeniable in order to carry through Vision 2020. This demand is supported by Rosnani ( 2009 ) who proclaims that Malaysians, in general, have non been able to use the content of cognition gained throughout their school old ages into existent life state of affairss even after undergone at least 11 old ages of schooling and hence, Malaysia educational system demand to be analysed and some alterations need to be made. Ministry of Education ( MOE ) has realised the dismaying demands of the aforesaid state of affairs and therefore, Integrated Curriculum for Secondary School ( KBSM ) was introduced in the late eightiess ( Nagappan, 2011 ) . The content of this new course of study was revamped in which originative and critical thought accomplishments were integrated in most of the topics taught in schools with a emphasis on treatment, find and enquiry ; the higher round of Bloom taxonomy ( Curriculum Development Center, 1989 ) . As it is realised that the instructors need to be competent to learn critical thought accomplishments to the pupils, a few attempts were besides been conducted as to fix the instructors and teachers-to-be with the new undertaking in front of them. As educational findings have reported that most instructors in Malayan schools are missing in footings of cognition and accomplishments to learn critical thought accomplishments to their pupils ( Education Reform in Malaysia Report, 2012 ) , a few amendments have been made to meet this job from the instructor ‘s portion. Nagappan ( 2001 ) studies that Teacher Education Division ( TED ) had revamped the course of study for Teacher Training Programme such as in Post Degree Teaching Programme ( KPLI ) in early 1994 to integrate a programme that teaches the schemes to learn believing accomplishments utilizing the extract attack which is based on Boston Model. As for the instructors in schools, Ministry of Education ( MOE ) had introduced the Programme for Instruction in Learning and Thinking Skills ( PILTS ) in 1992 ( Rosnani, 2009 ) . This programme was introduced to place the nucleus thought accomplishments to be taught and the schemes to inculcate these accomplishments into the content of the lesson being learnt. Apart from that, Ministry of Higher Education ( MOHE ) has besides made an effort to cultivate undergraduates ‘ critical thought accomplishments through the content and undertakings assigned throughout each programme. Harmonizing to Hairuzila, Hazadiah & A ; Normah ( 2010 ) , the course of study for undergraduates has been infused with relevant soft accomplishments such as communicative accomplishments, critical thought and job resolution accomplishments, womb-to-tomb acquisition, squad work force and leading accomplishments into its course of study. They further elaborate that in order to aline with Vision 2020 of bring forthing holistic persons for the state, the appraisals or undertakings given to the undergraduates are geared towards fixing them for their calling life as most are based on real-life jobs, with less emphasis on pen and paper trials like antecedently.Challenges in learning critical thought accomplishments in MalayaDue to the exam-oriented civilization that has been practised for old ages in Malayan instruction system, instructors are shouldered with the duty to complete the course of study and give every bit much boring exercisings as they can to their pupils as to maintain up with the society ‘s outlook and over-emphasis on academic consequences. This in return has caused the instructors paying the least attending to pupils ‘ character edifice and soft accomplishments such as critical thought accomplishment ( Education Reform in Malaysia Report, 2012 ) . It can be seen here that Malayan instructors are non merely missing in footings of accomplishments to learn critical thought accomplishments ( Rosnani, 2009 ) , but besides are less than competent to fix and carry on a lesson that infuses critical thought accomplishments in a traditional schoolroom. This is due to the fact that learning critical thought accomplishments needs a batch of clip allotment during the pre-preparation category and undivided committedness both of por tion of the instructor and pupils to guarantee an active advancement during the acquisition procedure ( Willingham, 2007 ) . Apart from that, large size schoolrooms in most Malayan schools are besides one of the grounds that contribute to the failure of incorporating critical thought accomplishments in learning a topic in traditional schoolroom. A study done by Kamaruddin ( 2011 ) stated that schoolroom in Malayan schools are by and large consists of 35 to 50 pupils per schoolroom. This indirectly shows that most pupils will look as inactive scholars and synergistic activities that are believed to cultivate pupils ‘ critical thought can non be good conducted in such large size category. In contrast, many surveies have shown that a little size category of 20 pupils and below are said to be efficient and frequently associated with increased pupils ‘ public presentation and therefore, most likely leting smooth nurturing procedure of their soft accomplishments ( Carson, Badarack, 1989 ; Berliner, 1990 ; Kamaruddin & A ; Bhasah, 2004 ) . The force per unit area to accomplish excellence in academic consequence in a less contributing environment in most of Malayan schools left the instructors with no pick but to fall back rehearsing teacher centred attack in go toing their duties. Hence, pupils are non given ample chance to see synergistic, active acquisition that could really assist to cultivate their critical thought accomplishments ( Kamaruddin, 2011 ) . Teacher centred attack, in return, will undeniably do one-way cognition transmittal to happen and hence, less opportunities being given to the pupils to convey their sentiments to actively build their ain cognition ( Willingham, 2007 ) . Without chance to actively build ain cognition, one is said to pay less attending to cultivate and foster his ain critical thought ( Toulmin, 1958 ) . Due to this state of affairs, most of Malayan pupils who are subsequently become employees are said to hold hapless communicating accomplishments and this visibly shows in their defic iency of ability to critically reassigning an sentiment or cognition when pass oning with others ( Education Reform in Malaysia Report, 2012 ) .Educational Learning Theory and SchemesDue to that, instructors ‘ manner of learning should pitch towards incorporating higher order believing accomplishments and rehearsing positive communicating accomplishments in order to bring forth holistic persons align with Vision 2020. Woolfolk ( 1993 ) suggests that theoretical foundation of acquisition and schemes used in a acquisition procedure will assist to model the type of pupils that a instructor wants to foster. Lai ( 2011 ) suggests the instruction of higher order believing accomplishments should be based on the followerss:Constructivism TheoryBruner ( 1996 ) stated that the basic thought of constructivism is that scholars actively construct ain apprehension by accepting certain experiences and choosing necessities from assorted beginnings of cognition. Naismith et. Al ( 2006 ) beside s claimed that constructivism attack is about constructing new cognition upon what have been gathered in old acquisition. Woolfolk ( 1993 ) stated that constructivist larning theory indirectly learning the pupils to â€Å" larn to larn † as it involves believing procedures in which pupils need to be able to travel beyond the information given, use their ain cognition, evaluate opinions before generate new thoughts out of it. Students are required to actively affect in the acquisition procedure to develop their thought accomplishments through their experiences in schools ( Prawat, 1991 ) . Lai ( 2001 ) stated that constructivism can be used as a foundation to foster one ‘s higher order believing accomplishments via self-questioning, analyzing written papers for comprehension and besides holding collaborative treatments with equals.Social Constructivist TheorySocial Constructivist Theory, on the other manus, is a theory that states each single cognitive development is at its best when one constructs the significance of new cognition by actively take parting in building and sharing the cognition through communicating with others ( Burningham & A ; Cooper, 1999 ) . These theories believes that equal to peer treatment will assist one to actively build new cognition and learn by sharing and discoursing the stuffs gathered in a positive societal environment ( Schwandt, 2003 ) .Problem Based Learning ( PBL )Teaching critical thought accomplishments is normally being paired with Problem Based Learning attack as it triggers and provokes scholars ‘ thought as to make to a solution to a job with relation to daily state of affairss ( Woolfolk, 1993 ) . Problem Based Learning ( PBL ) attack teaches pupils to believe critically as it takes existent universe fortunes which normally involves experiential, inductive acquisition that requires oppugning and believing that is purposive and purposive ( Lai, 2011 ) . More frequently than non, it involves a underta king that encourages the scholars to â€Å" larn to larn † which is an of import constituent in constructivist attack ( Kuhn, 1999 ) . This necessarily will promote active larning procedure including through speaking, brainstorming and in-depth probe of cognition via legion collaborative acquisition experiences.Collaborative acquisitionA figure of critical thought research workers recommended that societal experiences in a learning procedure can significantly lend to one ‘s cognitive development procedure which obviously occurred in a collaborative acquisition attack ( Heyman, 2008 ; Thayer-Bacon, 2008 & A ; Nelson, 1994 ) . This is farther supported by Woolfolk ( 1993 ) who claimed that collaborative acquisition is fundamentally based from Piagetian and Vygotsky theory which reciprocally agree that societal interactions extremely contribute to one ‘s cognitive development procedure. In a collaborative acquisition, it is believed that Piaget theory is applied in footings of its instructional facet in which scholar ‘s cognitive development can be triggered via interactions with another individual of a higher developmental phase which is usually the instructor or a more knowing equal ( Woolfolk, 1993 ) whilst Vygotsky belief is identified in footings of one ‘s zone of proximal development that distinguishes between what an person can achieved by himself and what can be accomplished via interactions with a more competent equal or grownup ( Nelson, 1994 ) . Thayer-Bacon ( 2008 ) further viewed that societal interactions with others in collaborative acquisition is an of import facet to instil critical thought accomplishments onto pupils as they need to constructively contribute and portion sentiments and at the same clip learn to esteem other parts during group treatments.Collaborative Problem Based Learning ( CPBL )Gokhale ( 1995 ) findings stated that pu pils who are actively engaged in a collaborative undertaking demonstrate better Higher Order Thinking Skills ( HOTS ) as compared to the 1s who work separately. This determination is farther supported by Vygotsky ( 1978 ) who claimed that collaborative acquisition helps to further the development of critical thought accomplishments via treatment, justification of thoughts and analyzing other ‘s positions. A few research findings have shown that uniting collaborative attack on job work outing learning scheme has really increase pupils ‘ meta-cognitive on work outing the jobs and therefore, better their higher order believing accomplishments ( Johnson & A ; Chung, 1999 ; Mergendoller et al. , 2000 ) . They further elaborate that the interaction between equals about the job at manus, brainstorming for solutions and measuring each other ‘s positions during the procedure has encouraged more frequent coevals of thoughts and solution and therefore, allow pupils to believe critically and analytically. Collaborative acquisition, as defined by Correndo and Alani ( 2007 ) , is an instructional scheme that consists of pupils from assorted proficiency degrees work together in a group while assisting each other towards accomplishing one common aim or larning result. On the other manus, Problem Based Learning is an instructional teaching method that uses job as a larning context to dispute the pupils to â€Å" larn to larn † in order to happen solutions to the job ( Duch, Groh & A ; Allen, 2001 ) . Hence, Collaborative Problem Based Learning ( CPBL ) is a combination of Collaborative Learning and Problem Based Learning which can be concluded as an instructional scheme that provides chances for the pupils to work within little groups and actively take part in assorted activities including treatments a state of affairs, analyzing others ‘ positions and eventually collaboratively measuring possible solution to the job at manus ( An, 2006 ) .The advantages of CPBLCPBL encourages pupils to work together in building new cognition to seek a solution of the job at manus. Hence, pupils are given huge chances to go critical minds by sharing thoughts and actively prosecuting oneself in treatments and be responsible of their ain acquisition every bit good as others ‘ ( Totten, Sills, Digby, & A ; Russ, 1991 ) . This place is farther supported by Johnson and Johnson ( 1986 ) who stated that the coaction on job work outing promotes higher degree of thought as the participants need to analyze others ‘ sentiment before clear uping ain sentiment. They farther claimed that this helps to advance longer cognition keeping as compared to the 1s who worked separately to seek cognition. Besides, An ( 2006 ) besides stated that CPBL provides reliable larning experiences every bit good as fostering their communicating accomplishments while interchanging thoughts during the treatments. Hence, CPBL helps to further autonomous acquisition accomplishments that could be utile to assist pupils go womb-to-tomb scholars and critical minds ( Norman and Schmidt, 1992 ) . Albanese and Mitchell ( 1993 ) besides proposed that pupils who undergone CPBL attack performed better than the 1s who received traditional attack in larning as they have first manus experience that rewards them with in-depth understanding about the undertaking at manus. This is believed because the pupils actively building their ain cognition via interaction with their equals ( Smith & A ; MacGregor, 2001 ) . Vygotsky ( 1978 ) besides views that instructor is non the lone cognition sender that the pupils can larn from ; equal instruction is besides one of the ways to promote active acquisition.The restrictions of CPBLDespite of these benefits, CPBL attack besides has its just portion of defects when it is being applied in a traditional schoolroom. In any group activities, particularly in a traditional schoolroom as it is rather hard for the instructor to accurately measure every pupil ‘s parts to the group, there is ever freeloading jobs. The freeloading members normally take credits of the work of others and this may do struggle amongst pupils ( Bower & A ; Richards, 2006 ) . Bower and Richards ( 2006 ) further stated that this may diminish some assurance of some pupils as psychologically, every pupil demand to be acknowledged where recognition is due in order for them to foster build their ain cognition in an active mode. They besides claimed that it is about impossible for the instructor to reasonably administer the grade based on every pupil ‘s part to the group. Hence, this may either do some pupils to either frustrated for being credited below the belt and subsequently de-motivated to lend in the hereafter or worse, become freeloaders and merely basking the free tiffin ( Bonwell, 2006 ) . Other than that, since CPBL activities need the pupils to collaboratively work towards accomplishing a end or solution to a real-life job, the readying of these activities are usually take great attempt and commitment both from the instructor and pupils. This is difficult to accomplish if it were to be done in a traditional schoolroom due to clip and infinite restraint ( Bonwell, 2002 ) . Apart from learning, Malayan instructors particularly, are burdened with other excess course of study or out of-school activities that take a batch of their personal clip ( Rosnani, 2009 ) . Without proper readying, CPBL that is hoped to promote pupils to actively build their ain cognition and at the same clip fostering their higher order and communicating accomplishments may non be turn into an accomplishable terminal ( Hmelo-Silver, 2004 ) . This is farther supported by Smith and MacGregor ( 2001 ) who claimed that collaborative acquisition is a fantastic attack to promote critical thought, nevert heless, it is besides may make quandary between pupil ‘s procedure of acquisition and the coverage of the lesson ‘s content.Computer Supported Collaborative Learning ( CSCL )Due to the rapid development of Information Technology ( IT ) in this modern age, these twenty-first Century pupils ‘ manner of acquisition has besides changed ( An, 2006 ) . Today, one of the ways to back up active acquisition can be materialised in a more fun manner through the usage of engineering tools. Computer Supported Collaborative Learning ( CSCL ) is an instructional scheme infused with constructivist attack to learning and larning utilizing engineering to back up coaction in order to make a more contributing and prosecuting larning atmosphere ( Johnson & A ; Johnson, 1996 ) . They farther stated that a technology-rich acquisition environment is able to increase pupils ‘ societal interaction, cooperation and coaction and therefore, promote their cognition building. Harasim, Hilt z, Teles, and Turoff ( 1995 ) besides claimed that CSCL promotes on-line collaborative acquisition that may positively promote pupils ‘ towards active acquisition. This is because pupils can acquire information about effortlessly via online and so discourse with their equals before emerge with a solution to a job.CPBL in an online environmentIn this epoch of rapid development of Information Technology ( IT ) , there have been attempts to unite CPBL into CSCL environment ( An, 2006 ) . Many research findings have indicated that CPBL in an online environment has been demoing positive effects towards pupils ‘ cognition building every bit good as societal interaction accomplishments. One of the fringe benefits by using CPBL into an on-line environment, apart from treatment with the teacher and their equals via online with no limitation to clip and topographic point, is that it encourages autonomous larning amongst pupils as it provides pupils with huge choices of information needed about effortlessly ( Bonk & A ; King, 1998 ) . This is because it allows the pupils to larn via Web 2.0 tools as larning AIDSs such as electronic mails, on-line group treatment in the confab suites, collaborative authorship via Wiki, societal bookmarking and so forth to go on anytime and anyplace. This limitless and easy entree on information will open ways for the pupils to accommodate to autonomous acquisition and therefore, promote active cognition building to happen. Besides, this online larning environment allows the function of the instructor as the exclusive supplier of cognition to transform into the function of facilitator, which aligns absolutely with student-centred attack in PBL ( Vrasidas & A ; McIsaac, 2000 ) . Here, pupils are encouraged to build their ain cognition with small counsel from the instructor and go an active subscriber towards their ain acquisition alternatively of passively having cognition from anyone else. This attack opens manner to cultivate one ‘s higher order believing accomplishments ( Harasim et al. , 1997 ) as it besides promotes positive interaction between the instructor and the pupils ( Relan & A ; Gillani, 1997 ) . Most significantly, Althaus, ( 1996 ) viewed that CPBL in an online environment allows computing machine mediated communicating that gives an ample clip for the pupils to analyze, reflect the content of the treatment, happen excess information needed via online and evaluate others ‘ sentiments before supplying a thoughtful response. The treatment via online besides allows the pupils to make self contemplation at their ain convenient clip as they can publish out the treatment due to its permanency discourse, as opposed to confront to confront treatment ( Bonk & A ; King, 1998 ) . Bower and Richards ( 2006 ) stated that one of the restrictions of utilizing PBL in a traditional schoolroom is that the collaborative treatment in a traditional schoolroom frequently consequences in off-task behavior amongst pupils. In contrast, many research findings have proven that pupils emit less off-task behavior in an on-line treatment and they tend to concentrate and intently work outing the job at manus ( Angeli et al. , 2003 ; Bonk et al. , 1998 ; Bonk & A ; King, 1998 ; Bonk et al. , 2004 ) . In fact, many psychological surveies have indicated that collaborative treatment via online shows more engagement from the pupils than the face to confront treatments ( Bonk & A ; King, 1998 ; Chong, 1998 ; Cooney, 1998 ) . This state of affairs is particularly true for the pupils who have shy personality or deficiency of ego assurance to speak publically. Leasure et Al. ( 2000 ) proposed that this could be due to the comfy and â€Å" safe † societal acquisition environment that the on-line atmosphere provides for these pupils. Here, it can be said that CPBL in an on-line environment is a possible acquisition attack to advance positive alterations in cultivating critical thought every bit good as to promote one ‘s societal interaction with others.2.8 Language larning issues in MalayaIn traveling towards carry throughing Vision 2020, instruction system in Malaysia is undergoing a few alterations as to bring forth holistic persons who are competent physically, emotionally, spiritually and intellectually ( Education Reform in Malaysia Report, 2012 ) . Along with the alterations introduced, Ministry of Education ( MOE ) has decided to incorporate the instruction of critical thought accomplishments within the course of studies of the topics taught in schools including English topic. The alterations is hoped to bring forth womb-to-tomb scholars who are able to believe critically and analytically over a given state of affairs. Sadly, nevertheless, the result of our instruction system has proven a contrasting consequence in which most of Malayan pupils and university undergraduates are said to be lacking in footings critical thought accomplishments and show hapless communicating abilities particularly when it is done in English ( Normazidah, Koo & A ; Hazita, 2012 ) . A survey by Koo ( 2008 ) revealed that this is due to the fact that Malaysians schools in general, placed a high value of importance on national scrutiny. This has indirectly caused the English instructors to concentrate on the instruction of grammar, reading a transition and composing accomplishments instead than concentrating on the communicative facet of the linguistic communication itself, allow entirely to model pupils ‘ critical thought ability while larning the linguistic communication ( Normazidah, Koo & A ; Hazita, 2012 ) . This is farther supported by Amigapathy ( 2002 ) findings on his analysis of KBSM course of study which indicated that the content of current course of study requires the pupils to larn excessively many grammatical constituents which subsequently are to be tested in scrutinies. Here, it can be seen that the instruction of English is chiefly focused on the mechanical facet of the linguistic communication without doing any connexion with how it should be used in existent life communicative events. He farther documented that in order to carry through the demands of the society to bring forth pupils with good classs in scrutinies, English instructors in Malaysia frequently resorted to teacher-centred attack in learning the linguistic communication by supplying chalk-and-talk boring method of past twelvemonth documents, manus outs and infinite paper exercises. This finally will necessarily bring forth scholars who know about the linguistic communication but do non cognize how to utilize it in existent life state of affairss ( Amigapathy, 2002 ) , show limited critical ability in analyzing and reacting to an academic transition ( Ahmad Mazli Muhammad, 2007 ) as pupils are merely exposed to come up attack to reading ( Noorizah Mohd Noor, 2006 ) . Here, it can be concluded that there is a mismatch between the policy made with the existent practise of instruction and acquisition of English in Malaysia which make it rather hard to bring forth scholars as critical minds with acceptable degree of English proficiency. This state of affairs is reported leads to a greater job when the pupils make the passage from secondary school to university as the pupils will confront jobs to travel off from school spoon-feeding learning civilization ( Normazidah, Koo & A ; Hazita, 2012 ) . Research surveies have indicated that most Malayan pupils are non prepared to run into the academic demand that requires them to hold both linguistic communication literacy every bit good as critical literacy ability in order to carry through the academic reading and academic authorship undertakings imposed on them at university ( Rosniah Mustaffa, 2006 ; Krishnakumari, Paul-Evanson, & A ; Selvanayagam, 2010 ) . Therefore, it is safe to state that the clip has come for Malayan instructors to handle the pupils as the focal point of linguistic communication acquisition by doing a little alterations in learning the linguistic communication and at the same clip, whenever possible, supplying a contributing environment of larning. As CPBL is geared towards cultivating one ‘s critical thought ability ( An, 2006 ; Totten, Sills, Digby, & A ; Russ, 1991 ) and critical thought accomplishments is viewed as important portion in the acquisition of linguistic communication accomplishments ( Elder & A ; Paul, 2006 ; Shaharom Abdullah, 2004 ; Moore, 1995 ) , it merely seems appropriate to accommodate CPBL attack in the instruction and acquisition of English in Malaysian schoolrooms. Besides, linguistic communication acquisition can besides be mediated via engineering tools because as mentioned earlier, CPBL in an on-line environment brings enormous advantages and benefits to the pupils in footings of critical thought and linguistic communication acquisition as it involves legion chances for societal interactions amongst the pupils and pedagogue.Technology, linguistic communication acquisition and critical thoughtTechnology has besides been proven utile in the instruction of linguistic communication and development of one ‘s critical thought at clip and infinite convenient to both the instructor and pupils ( Cheong & A ; Cheung, 2008 ) . For case, the treatments in the treatment boards or chew the fat suites between the pupils and the instructor and besides between pupils have been used as a medium to positively develop pupils ‘ communicating accomplishments every bit good as linguistic communication accomplishments ( Chitravelu, Sithamparam and Teh, 2005 ) . Kroop, Nussbaumer and Fruhmann ( 2010 ) reported that the development of Web 2.0 tools are able to better one ‘s linguistic communication skills every bit good as support one ‘s critical thought accomplishments development by leting its users to make collaborative treatment that includes discussing, reasoning, reexamining, measuring, composing and re-producing an thought. By utilizing Web 2.0 tools such as electronic mails, treatments in confab suites or treatment boards that could be done either synchronously or asynchronously, pupils become more participative and therefore, bettering their linguistic communication and communicative accomplishments ( Berry, 2006 ) . Another Web 2.0 tools that is often used in an on-line environment to learn linguistic communication is Wiki. Wiki is said has the potency to better pupils ‘ linguistic communication accomplishments every bit good as communicating and thought accomplishments ( Goodings, 2008 ) . Fuchs-Kittowski and Kohler ( 2005 ) mentioned that Wikis is able to ease the collaborative treatments that encourage coevals of cognition by supplying a medium to portion creative activity and edit paperss. Bruns and Humphreys ( 2005 ) besides added that Wiki is a learning tool that support societal constructivist larning as it allows argumentative-based larning experience ( Chong & A ; Yamamoto, 2006 ) , facilitates knowledge determining ( Reinhold, 2006 ) , allows coaction ( Kim et al. , 2006 ) and allows enquiry acquisition and collaborative building of cognition ( Yukawa, 2006 ) . This procedure is known as Argumentative Knowledge Construction. Knowledge building within a traditional schoolroom is frequently relied to a great extent on the instructors which necessarily produce inactive scholars who may or may non be able to critically decode the cognition received to use it in existent life state of affairs ( Weible, 2011 ) . By utilizing Web 2.0 tools, on the other manus, it encourages and facilitates active engagement of each user as everyone has a just portion and chance to make, portion, edit, add on and go through the cognition and these actions reinforce single ‘s cognition building by actively larning from others ( Correndo & A ; Alani, 2007 ) . Besides, Web 2.0 tools value are increased as the more people are utilizing it as the content cognition and the information are provided chiefly by the users and construct up over the clip with other users ‘ part ( Weible, 2011 ) . This procedure encourages argumentative cognition building amongst its users as they learn from each other and develop higher other be lieving accomplishments as the users need to measure others ‘ sentiment apart from offering one in the treatment. This is in line with constructivism attack in which larning takes topographic point and retain longer when it is achieve via societal context ( Woolfolk, 1993 ) .Argumentative Knowledge ConstructionHarmonizing to Weinberger and Fischer ( 2006 ) , Argumentative Knowledge Construction is described as a manner for the pupils to build their ain cognition via educational debate and interaction with their learning spouses. They besides stated that each single cognition building is depends on is refined and evidenced throughout their active engagement in analyzing sentiments of others, measuring possible solutions or results available from emerge with ain point of views via treatment and debate with equals.Argumentative Knowledge Construction in CPBLAalst ( 2009 ) stated that Argumentative Knowledge Construction is a procedure in which the pupils solve a job and concept m eaningful comprehension of a peculiar state of affairs in relation to their anterior cognition by societal interaction within a peculiar group. He farther added it involves a huge sphere of cognitive procedures as it involves critical-explanation seeking oppugning techniques, construing and analyzing new information, sharing, knocking, reorganizing thoughts, sum uping and synthesising before emerge with a new construct of the affair. In CPBL, for illustration, pupils learn by take parting in experiential acquisition and garner the indispensable cognition by work outing a job and reflecting on their collaborative experiences ( Hmelo-Silver, 2004 ) . CPBL activities encourage pupils to work in little collaborative groups in order to look into, understand, explicate and happen a solution to meaningful, real-life contexts ( Barrow, 2000 ) . He farther viewed that CPBL attack is widely used to cultivate one ‘s critical thought accomplishments as its acquisition procedure starts by showing the pupils with a job scenario in which the pupils try to work out the job collaboratively by place the lacks within the job, sharing sentiments and facts before coming out with hypotheses as to critically supply solutions to the job. Therefore, it can be said that CPBL is a suited attack to learn pupils to develop schemes in work outing jobs which may heighten their critical thought ability and besides assist them to heighten their argumentative cognition building ( Hmelo-Silver, 2004 ) .Argumentative Knowledge Construction in CSCLStudent ‘s argumentative cognition building procedure can be enhanced rather expeditiously through pupils ‘ treatments and composing with the assistance of fast growing and spread of Web 2.0 engineering, particularly in linguistic communication instruction and acquisition ( Stegmann et al. , 2007 ) . Bocconi ( 2010 ) proposed that CSCL may help to the Argumentative Knowledge Construction via the usage of Web 2.0 tools integrates with societal package to ease pupils interaction and coaction within a peculiar group. This is an accomplishable state of affairs as Web 2.0 tools such as weblogs, wikis, societal bookmarking, treatment boards, societal networking sites and others allow its users to pool information that triggers communications that leads to knowledge sharing and therefore, cognition is constructed ( Strijbos, Martens and Jochems, 2004 ) . Apart from that, the research conducted by Boulos et Al. ( 2006 ) stated that Wikis have the possible to ease autonomous acquisition of one to build ain cognition in order to derive deeper apprehension over a affair. Another research done by Bocconi ( 2010 ) shows that the usage of Web 2.0 tools, the Wikis to be specific, has shown positive consequence to catapult pupil ‘s argumentative cognition building procedure by analyzing the quality and frequence of the single argumentative Acts of the Apostless throughout the procedure. This is farther supported by Armin et Al. ( 2006 ) who claimed that by utilizing Wiki, pupils learn how to reason within a sphere and facilitates scholars in building their ain cognition and this taking them to a deeper apprehension. Bocconi ( 2010 ) stated that pupils ‘ higher order believing accomplishments are evidenced via their statements throughout the treatment procedure. He farther suggested that one of the methods to analyze and supervise pupils ‘ statement that emits their degree of higher order believing accomplishments can be done by utilizing Models of Argument such as Toulmin ‘s ModelModels of ArgumentationModel of Argumentation is defined as the basic layout as to sketch the best possible ways to organize an effectual procedure of common sense logical thinking or controversy in supplying a persuasive point of views ( Georgia State University, Department of English, 2008 ) . There are a few theoretical accounts of debate that are widely used in educational discourse in linguistic communication acquisition viz. the Classical Approach, the Rogerian Approach and the Toulmin Approach. The Classical Approach is fundamentally used to convert the audience to hold and take side or do determination that favours one ‘s personal point of view ( Beale, 1986 ) . He farther elaborates that this attack consists of five elements of composing the statements viz. the Introduction in which to province the general claim of an statement to the audience ; the Narration as to supply a relevant drumhead background of peculiar state of affairs ; the Confirmation as to supply back uping grounds to a claim. Then, it is followed by the Refutation in which the talker or author provides a counter-argument to any opposing claims before terminals it with the Conclusion as to which the talker or author summarizes the chief points and reiterates the claim made in Introduction portion. The Rogerian Approach, on the other manus, is based on the thought that the talker or the author needs to happen a â€Å" common land † with his audience as to make to a more conciliatory and less confrontational solution ( Moxley, 2012 ) . There are besides chiefly five elements in sketching debate thoughts harmonizing to Rogerian Model of Argumentation. It begins with an Introduction that province the issue ; followed by a non-judgemental opposition ‘s place ; a impersonal statement of ain point of view ; an analysis of common land of both places stated and eventually a proposal of concluding statement that satisfies the demands of both places made. Whilst Toulmin ‘s Model of Argumentation in which it was developed by a British philosopher, Stephen Toulmin. He suggested that a realistic statement normally starts with a individual makes a claim over a affair, so supply a land that support the claim which is followed by a warrant to endorse up the land made ( Toulmin, 1958 ) . This is the Model of Argumentation chosen to be used in this survey and will be elaborated at length below.Toulmin ‘s ModelHarmonizing to Toulmin ( 1958 ) , his strategy of statement analysis is based on six parts, which could be depicted utilizing Figure 2.1 as follows:DatasClaimWarrantsBackingQualifierRebuttalFigure 2.1: Toulmin ‘s Model of Argument Claim: the statement or decision being argued ; Datas: The grounds or fact to back up the claim made ; Warrants: the logical statements that serve as a connexion between the informations and the claim made ; Backing: the basic premise that is made to farther support a warrant ; Qualifiers: states the restriction under which state of affairs the claim can be regarded as true ; Rebuttals: the counter statements to picture circumstance when the claim made is non true. ( Toulmin, 1958 ) In add-on, Bocconi ( 2010 ) indicated that the basic construction of each of these phases can be identified and represented as follows: â€Å" because ( informations ) . . . since ( warrant ) . . . on history of ( endorsing ) . . . therefore ( decision ) † Bocconi ( 2010 ) Karbach ( 2010 ) stated that Toulmin suggested that one ‘s statement can be analysed by looking at his or her cognition building at four stairss viz. ; claim, informations, rebuttal and backup as to see whether the statement made solidly backed, sufficient and relevant to back up the old statements made. Hence, Karbach ( 2010 ) believed that Toulmin ‘s Model of Argumentation is a clear theoretical account to observe one ‘s inductive, deductive and logical logical thinking. Kneupper ( 1978 ) besides viewed that this layout strategy can be efficaciously used to analyze the constituents of an statements in linguistic communication acquisition.DecisionThe instruction of higher order believing accomplishments can non be taught in isolation ( Lai, 2011, Nagappan, 2001 ) . Hence, it has to be integrated into the course of study as to supply the pupils with the existent life medium and purposeful acquisition results apart from its importance to cultivate one ‘s critic al thought and communicating accomplishments ( Education Reform in Malaysia Report, 2012 ) . In this fast growing of Information Technology ( IT ) epoch, the usage of engineering such as Web 2.0 tools can be used to efficaciously heighten the instruction of these accomplishments anytime anyplace ( Winston, 2006 ) . Besides, the usage of these engineering tools are proven to be effectual to promote pupils to larn collaboratively as human makes significances and can make at a deeper apprehension by pass oning with others ( Vygotsky, 1978 ; Johnson and Johnson, 1986 ; Gokhale,1995 ; An, 2006 ) . Through the communicating and interaction in a collaborative treatment via online, one can actively develop his or her ain cognition building in order to organize deeper apprehension in a safe and unafraid societal environment ( Chitravelu, Sithamparan & A ; Teh, 2005 ; Weinberger & A ; Fischer, 2006 ) .

Fish Production

FISH PRODUCTION Aim: This task considers commercial fishing in a particular country in two different environments- the sea and fish farms (aquaculture). The data is taken from the UN Statistics Division Common Database. *The following table gives the total mass of fish caught in the sea, in thousands of tonnes (1 tonne = 1000 kilograms) Define suitable variables and discuss any parameters/ constraints. Using technology, plot the data points form the table on a graph. Comment on any apparent trends in your graph and suggest suitable models. Aquaculture pros and cons Pros Feeds the world's demand for seafood Has a tremendous economic impact on world GDP Cons Major impact it has on the ecology of the oceans Utilizes nets or traps may inadvertently capture and kill other marine animals, including turtles, dolphins or sharks. 70 percent of the world's fish species are depleted† or â€Å"fully exploited. † † Wild fish are usually healthier (higher in Omega-3s) and less c ontaminated than farmed fish. Employs more than 200 million people around Overfishing he globe Many people prefer the taste of wild fish. The shipping of fish all over the world uses Farmed fish do not have as much room to fossil fuels and pollutes the environment. move which results in partial growth. http://www. sparkpeople. com/resource/nutrition_articles. asp? id=1282 Using technology, plot the data points from the table on a graph. Overall it seems as though the trend of the mass of fish caught in the sea follows an unpredictable pattern. The mass of fish increases at its highest from 1980-1988.From then onwards it takes it biggest plummet from 1988-1991, then increases rapidly from 1991-1995. After that there are at sharp increases which then follow sharp decreases which can be seen from 1995-2006. The mass of the fish between those time periods follow an up and down then up and down form of pattern. Fish caught at sea can have variables such as weather, temperature, and seaso n that affect it. These variables cannot be controlled no can they be changed, this in return directly affects the mass of the fish caught each year. The following table gives the total mass of fish, in thousands of tonnes, from fish farms. (1 tonne = 1000 kilograms) *Aquaculture pros and cons Pros Can reduce seafood trade deficit Can help feed a growing world population Cons Can conflict with other users of water bodies such as fishermen or migrating fish Can put excess pressure on wild stocks that are used to create high protein feed pellets Can amplify and transfer disease and parasites to wild fish populations Can pollute water systems with excess utrients (fish feed & wastes), chemicals and antibiotics Can threaten livelihood of fishermen Can increase scientific knowledge and technology Can place more emphasis on protecting coastal waters from pollution, especially in the case of mollusk and seaweed culture. May reduce fishing pressure on certain wild stocks if that species can be produced through aquaculture rather than fished. http://www. pbs. org/emptyoceans/educators/activities/docs/Aquaculture-Pros-and-Cons. pdf Using technology, plot the data points from the table on a graph.Overall the mass of the fish from fish farms seems to be increasing exponentially. This increase could be seen from 1980-2000, then from 2002-2006. The only decrease seen in this graph is from 2000-2002. This form of fishing, unlike fish caught in the sea, is unnatural. Almost every variable that could affect the mass and growth of the fish can be changed and interrupted primarily by humans. This gives it more of an advantage than fishing from the sea because as seen in the two different graphs, the fish farm’s graph is increases more rapidly and can also be predicted.
