    PREFACE

    The aspiration of the nation to become an industrialised societydepends on science and technology. It is envisaged that successin providing quality science education to Malaysians from an earlyage will serve to spearhead the nation into becoming a knowledgesociety and a competitive player in the global arena. Towards thisend, the Malaysian education system is giving greater emphasis toscience and mathematics education.

    The Physics curriculum has been designed not only to provideopportunities for students to acquir e science knowledge and skills,develop thinking skills and thinking strategies, and to apply thisknowledge and skills in everyday life, but also to inculcate in themnoble values and the spirit of patriotism. It is hoped that the

    educational process en r oute to achieving these aims wouldproduce well-balanced citizens capable of contributing to theharmony and prosperity of the nation and its people.

    The Physics curriculum aims at producing active learners. To thisend, students are given ample opportun ities to engage in scientificinvestigations through hands -on activities and experimentations.The inquiry approach, incorporating thinking skills, thinkingstrategies and thoughtful learning, should be emphasisedthroughout the teaching -learning process. The content andcontexts suggested are chosen based on their relevance andappeal to students so that their interest in the subject is enhanced.

    In a recent development, the Government has made a decision tointroduce English as the medium of i nstruction in the teaching andlearning of science and mathematics. This measure will enablestudents to keep abreast of developments in science andtechnology in contemporary society by enhancing their capabilityand know-how to tap the diverse sources of information on sciencewritten in the English language. At the same time, this move wouldalso provide opportunities for students to use the English languageand hence, increase their proficiency in the language. Thus, inimplementing the science curricul um, attention is given todeveloping students ability to use English for study andcommunication, especially in the early years of learning.

    The development of this curriculum and the preparation of thecorresponding Curriculum Specifications have been the work ofmany individuals over a period of time. To all those who havecontributed in one way or another to this effort, may I, on behalf ofthe Ministry of Education, express my sincere gratitude and thanksfor the time and labour expended.

    INTRODUCTION

    As articulated in the National Education Policy, education inMalaysia is an on -going effort towards developing the potential of

    individuals in a holistic and integrated manner to produce individualswho are intellectually, spiritually, emotionally and physicallybalanced and harmonious. The primary and secondary schoolscience curriculum is developed with the aim of producing suchindividuals.

    As a nation that is progressing towards a developed nationstatus, Malaysia needs to create a society that is scientificallyoriented, progressive, knowledgeable, having a high capacity forchange, forward-looking, innovative and a contributor to scientif icand technological developments in the future. In line with this, thereis a need to produce citizens who are creative, critical, inquisitive,open-minded and competent in science and technology.

    The Malaysian science curriculum comprises three corescience subjects and four elective science subjects. The coresubjects are Science at primary school level, Science at lowersecondary level and Science at upper secondary level. Electivescience subjects are offered at the upper secondary level andconsist of Biology, Chemistry, Physics, and Additional Science.

    The core science subjects for the primary and lowersecondary levels are designed to provide students with basic

    science knowledge, prepare students to be literate in science, andenable students to continue their science education at the uppersecondary level. Core Science at the upper secondary level isdesigned to produce students who are literate in science,

    innovative, and able to apply scientific knowledge in decision -making and problem solving in everyday life.

    The elective science subjects prepare students who aremore scientifically inclined to pursue the study of science at post -secondary level. This group of students would take up careers inthe field of science and technology and play a leading role in thisfield for national development.

    For every science subject, the curriculum for the year isarticulated in two documents: the syllabus and the curriculumspecifications. The syllabus presents the aims, objectives and theoutline of the curriculum content for a period of 2 years for electivescience subjects and 5 years for core science subjects. Thecurriculum specifications provide the details of the curriculumwhich includes the aims and objectives of the curriculum, briefdescriptions on thinking skills and thinking strategies, scientificskills, scientific attitudes and noble values, teaching and learningstrategies, and curriculum content. The curriculum contentprovides the learning objectives, suggested learning activities, theintended learning outcomes, and vocabulary.

    SCIENTIFIC SKILLS

    Science emphasises inquiry and problem solving. In inquiry andproblem solving processes, scientific and thinking skills are

    utilised. Scientific skills are important in any scientific investigationsuch as conducting experiments and carrying out projects.

    Scientific skills encompass science process skills and manipulativeskills.

    Science Process Skills

    Science process skills enable students to formulate their questionsand find out the answers systematically.

    Descriptions of the science process skills are as follows:

    Observing Using the sense of hearing, touch,smell, taste and sight to collectinformation about an object or aphenomenon.

    Classifying Using observations to groupobjects or events according tosimilarities or differences.

    Measuring andUsingNumbers

    Making quantitative observationsusing numbers and tools withstandardised unit s. Measuringmakes observation more accurate.

    Inferring Using past experiences orpreviously collected data to draw

    conclusions and explain events.

    Predicting Stating the outcome of a futureevent based on prior knowledgegained through experiences orcollected data.

    Communicating Using words or graphic symbolssuch as tables, graphs, figuresor models to describe an action,

    object or event.

    Using Space-TimeRelationship

    Describing changes inparameter with time. Examplesof parameters are location,direction, shape, size, volume,weight and mass.

    Interpreting Data Giving rational explanationsabout an object, event or patternderived from collected data.

    DefiningOperationally

    Defining concepts by describingwhat must be done and whatshould be observed.

    Controlling

    VariablesIdentifying the fixed variables,manipulated variable, andresponding variable in aninvestigation. The manipulatedvariable is changed to observeits relationship with theresponding variable. At thesame time, the fixed variablesare kept constant.

    Hypothesising Making a general statement

    about the relationship between amanipulated variable and aresponding variable in order toexplain an event or observation.This statement can be tested todetermine its validity.

    Experimenting Planning and conductingactivities to test a certainhypothesis. These activitiesinclude collecting, analysing

    and interpreting data andmaking conclusions.

    Manipulative Skills

    Manipulative skills in scientific investigation are psycho motor skillsthat enable students to:

    ? use and handle science apparatus and laboratory substancescorrectly.

    ? handle specimens correctly and carefully.

    ? draw specimens, apparatus and laboratory substancesaccurately.

    ? clean science apparatus correctly, and

    ? store science apparatus and laboratory substances correctlyand safely.

    THINKING SKILLS

    Thinking is a mental process that requires an individual to integrateknowledge, skills and attitude in an effort to understand theenvironment.

    One of the objectives of the national education system is toenhance the thinking ability of students. This objective can beachieved through a curriculum that emphasises thoughtfullearning. Teaching and learning that emphasises thinking skills is afoundation for thoughtful learning.

    Thoughtful learning is achieved if students are actively involved inthe teaching and learning process. Activities should be organised

    to provide opportunities for students to apply thinking skills inconceptualisation, problem solving and decision-making.

  • 8/3/2019 Hsp Physics f5

    Thinking skills can be categorised into critical thinking skills andcreative thinking skills. A person who thinks critically alwaysevaluates an idea in a systematic manner before accepting it. Aperson who thinks creatively has a high level of imagination, isable to generate original and innovative ideas, and modify ideasand products.

    Thinking strategies are higher order thinking processes thatinvolve various steps. Each step involves various critical andcreative thinking skills. The ability to formulate thinking strategiesis the ultimate aim of introducing thinking activities in the teachingand learning process.

    Critical Thinking Skills

    A brief description of each critical thinking skill is as follows:

    Attributing Identifying criteria such ascharacteristics, features,qualities and elements of aconcept or an object.

    Comparing andContrasting

    Finding similarities anddifferences based on criteriasuch as characteristics,features, qualities andelements of a concept orevent.

    Grouping andClassifying

    Separating and groupingobjects or phenomena intocategories based on certaincriteria such as commoncharacteristics or features.

    Sequencing Arranging objects andinformation in order based onthe quality or quantity o fcommon characteristics orfeatures such as size, time,shape or number.

    Prioritising Arranging objects andinformation in order based ontheir importance or priority.

    Analysing Examining information in detailby breaking it down intosmaller parts to find implicitmeaning and relationships.

    Detecting Bias Identifying views or opinionsthat have the tendency tosupport or oppose somethingin an unfair or misleading way.

    Evaluating Making judgements on thequality or value of somethin gbased on valid reasons orevidence.

    MakingConclusions

    Making a statement about theoutcome of an investigationthat is based on a hypothesis.

    Creative Thinking Skills

    A brief description of each creative thinking skill is as follows:

    Generating Ideas Producing or giving ideas in adiscussion.

    Relating Making connections in asituation to determine astructure or pattern ofrelationship.

    MakingInferences

    Using past experiences orpreviously collected data todraw conclusions and makeexplanations of events.

    Predicting Stating the outcome of a futureevent based on priorknowledge gained throughexperiences or collected data.

    MakingGeneralisations

    Making a general conclusionabout a group based onobservations made on, orsome information from,samples of the group.

    Visualising Recalling or forming mental

    images about a particular idea,concept, situation or vision.

    Synthesising Combining separate elements

    or parts to form a generalpicture in various forms suchas writing, drawing or artefact.

    MakingHypotheses

    Making a general statementon the relationship betweenmanipulated variables andresponding variables in orderto explain a certain thing orhappening. This statement isthought to be true and can be

    tested to determine its validity.

    Making Analogies Understanding an abstract ora complex concept by relatingit to a simpler or concreteconcept with similarcharacteristics.

    Inventing Producing something new oradapting something already inexistence to overcomeproblems in a systematicmanner.

    Thinking Strategy

    Description of each thinking strategy is as follows:

    Conceptualising Making generalisations basedon inter-related and commoncharacteristics in order toconstruct meaning, concept ormodel.

    Making Decisions Selecting the best solution fromvarious alternatives based onspecific criteria to achieve aspecific aim.

    Problem Solving Finding solutions to challengingor unfamiliar situations orunanticipated difficulties in asystematic manner.

    Besides the above thinking skills and thinking strategies,another skill emphasised is reasoning. Reasoning is a skillused in making logical, just and rational judgements.Mastering of critical and creative thinking skills and think ingstrategies is made simpler if an individual is able to reason inan inductive and deductive manner. Figure 1 gives a generalpicture of thinking skills and thinking strategies.

    Mastering of thinking skills and thinking strategies (TSTS)through the teaching and learning of science can be developed

    through the following phases:

    1. Introducing TSTS.2. Practising TSTS with teachers guidance.3. Practising TSTS without teachers guidance.4. Applying TSTS in new situations with teachers guidance.5. Applying TSTS together with other skills to accomplish

    thinking tasks.

    Further information about phases of implementing TSTS can befound in the guidebook Buku Panduan Penerapan KemahiranBerfikir dan Strategi Berfikir dalam Pengajaran dan Pembelajaran

    Sains(Curriculum DevelopmentCentre, 1999).

    Relationship between Thinking Skills andScience Process Skills

    Science process skills are skills that are required in the process offinding solutions to a pro blem or making decisions in a systematic

    manner. It is a mental process that promotes critical, creative,analytical and systematic thinking. Mastering of science processskills and the possession of suitable attitudes and knowledgeenable students to think effectively.

    The mastering of science process skills involves themastering of the relevant thinking skills. The thinking skills that arerelated to a particular science process skill are as follows:

    Teaching and Learning based on Thinking Skillsand Scientific Skills

    This science curriculum emphasises thoughtful learning based onthinking skills and scientific skills. Mastery of thinking skills andscientific skills are integrated with the acquisition of knowledge inthe intended learning outcomes. Thus, in teaching and learning,teachers need to emphasise the mastery of skills together with theacquisition of knowledge and the inculcation of noble values andscientific attitudes.

    The following is an example and explanation of a learning outcomebased on thinking skills and scientific skills.

    Example:

    Learning Outcome: Deduce from the shape of a velocity -time graph when a body is:i. at restii. moving with uniform velocityiii. moving with uniform acceleration.

    Thinking Skills: analysing, relating

    Explanation:

    To achieve the above learning outcome, students must firstanalyse graphs to relate the shape of the graph to the motion ofan object.

    SCIENTIFIC ATTITUDES AND NOBLE VALUES

    Science learning experiences can be used as a means to inculcatescientific attitudes and noble values in students. These attitudesand values encompass the following:

    ? having an interest and curiosity towards the environment.

    ? being honest and accurate in recording and validating data.? being diligent and persevering.

    ? being responsible about the safety of oneself, others, and theenvironment.

    ? realising that science is a means to unders tand nature.? appreciating and practising clean and healthy living.

    ? appreciating the balance of nature.

    ? being respectful and well -mannered.

    ? appreciating the contribution of science and technology.

    ? being thankful to god.? having critical and analytical think ing.

    ? being flexible and open-minded.

    ? being kind-hearted and caring.

    ? being objective.

    ? being systematic.? being cooperative.

    ? being fair and just.

    ? daring to try. ? thinking rationally.

    ? being confident and independent.

    The inculcation of scientific attitudes a nd noble values generallyoccurs through the following stages:

    ? being aware of the importance and the need for scientificattitudes and noble values.

    ? giving emphasis to these attitudes and values.? practising and internalising these scientific attitudes and noble

    values.

    When planning teaching and learning activities, teachersneed to give due consideration to the above stages to ensure thecontinuous and effective inculcation of scientific attitudes andvalues. For example, during science practical work, the teachershould remind pupils and ensure that they carry out experiments ina careful, cooperative and honest manner.

    Proper planning is required for effective inculcation ofscientific attitudes and noble value s during science lessons. Beforethe first lesson related to a learning objective, teachers shouldexamine all related learning outcomes and suggested teaching -learning activities that provide opportunities for the inculcation of

    scientific attitudes and n oble values.

    The following is an example of a learning outcomepertaining to the inculcation of scientific attitudes and values.

    Example:

    Discuss the importance of safetyfeatures in vehicles.

    Scientific attitudes andnoble values

    Appreciating the contribution ofscience and technology.

    Having critical and analyticalthinking.

    Inculcating Patriotism

    The science curriculum provides an opportunity for thedevelopment and strengthening of patriotism among students. Forexample, in learning about the earths resources, the richness andvariety of living things and the development of science andtechnology in the country, students will appreciate the diversity ofnatural and human resources of the country and deepen their lovefor the country.

    TEACHING AND LEARNING STRATEGIES

    Teaching and learning strategies in the science curriculumemphasise thoughtful learning. Thoughtful le arning is a processthat helps students acquire knowledge and master skills that willhelp them develop their minds to the optimum level. Thoughtful

    learning can occur through various learning approaches such asinquiry, constructivism, contextual learning , and mastery learning.Learning activities should therefore be geared towards activatingstudents critical and creative thinking skills and not be confined toroutine or rote learning. Students should be made aware of thethinking skills and thinking str ategies that they use in their learning.

    They should be challenged with higher order questions andproblems and be required to solve problems utilising their creativityand critical thinking. The teaching and learning process shouldenable students to acqu ire knowledge, master skills and developscientific attitudes and noble values in an integrated manner.

    Teaching and Learning Approaches in Science

    Inquiry-Discovery

    Inquiry-discovery emphasises learning through experiences.Inquiry generally means to find information, to question and toinvestigate a phenomenon that occurs in the environment.Discovery is the main characteristic of inquiry. Learning throughdiscovery occurs when the main concepts and principles ofscience are investigated and discover ed by students themselves.Through activities such as experiments, students investigate aphenomenon and draw conclusions by themselves. Teachers thenlead students to understand the science concepts through theresults of the inquiry. Thinking skills and scientific skills are thusdeveloped further during the inquiry process. However, the inquiryapproach may not be suitable for all teaching and learning

    situations. Sometimes, it may be more appropriate for teachers topresent concepts and principles dir ectly to students.

  • 8/3/2019 Hsp Physics f5

    23/56

    12

    Constructivism

    Constructivism suggests that students learn about somethingwhen they construct their own understanding. The importantattributes of constructivism are as follows:

    ? taking into account students prior knowledge.? learning occurring as a result of students own effort. ? learning occurring when students restructure their

    existing ideas by relating new ideas to old ones.? providing opportunities to cooperate, sharing ideas and

    experiences, and reflecting on their learni ng.

    Science, Technology and Society

    Meaningful learning occurs if students can relate their learning withtheir daily experiences. Meaningful learning occurs in learningapproaches such as contextual learning, and Science, Technology

    and Society (STS).

    Learning themes and learning objectives that carry elements ofSTS are incorporated into the curriculum. STS approach suggeststhat science learning takes place through investigation anddiscussion based on science and technology issues in society. Inthe STS approach, knowledge in science and technology is to belearned with the application of the principles of science andtechnology and their impact on society.

    Contextual Learning

    Contextual learning is an approach that associates learning withdaily experiences of students. In this way, students are able toappreciate the relevance of science learning to their lives. Incontextual learning, students learn through investigations as in theinquiry-discovery approach.

    Mastery Learning

    Mastery lea rning is an approach that ensures all students are ableto acquire and master the intended learning objectives. Thisapproach is based on the principle that students are able to learn if

    they are given adequate opportunities. Students should be allowedto learn at their own pace, with the incorporation of remedial andenrichment activities as part of the teaching -learning process.

    Teaching and Learning Methods

    Teaching and learning approaches can be implemented throughvarious methods such as experiments, discussions, simulations,projects, and visits. In this curriculum, the teaching -learningmethods suggested are stated under the column SuggestedLearning Activities. However, teachers can modify the suggestedactivities when the need arises.

    The use of a variety of teaching and learning methods canenhance students interest in science. Science lessons that arenot interesting will not motivate students to learn and subsequentlywill affect their performance. The choice of teaching methodsshould be based on the curriculum content, students abilities,students repertoire of intelligences, and the availability ofresources and infrastructure. Besides playing the role ofknowledge presenters and experts, teachers need to act asfacilitators in th e process of teaching and learning. Teachers need

    to be aware of the multiple intelligences that exist among students.Different teaching and learning activities should be planned tocater for students with different learning styles and intelligences.

    The following are brief descriptions of some teaching and learningmethods.

    Experiment

    An experiment is a method commonly used in science lessons. In

    experiments, students test hypotheses through investigations todiscover specific science concepts and principles. Conducting anexperiment involves thinking skills, scientific skills, andmanipulative skills.

    Usually, an experiment involves the following steps:

    ? identifying a problem.? making a hypothesis.? planning the experiment

    - controlling variables.

    - determining the equipment and materials needed.- determining the procedure of the experiment andthe method of data collection and analysis.

    ? conducting the experiment.? collecting data.? analysing data.? interpreting data.? making conclusions.? writing a report.

    In the implementation of this curriculum, besides guiding studentsto do an experiment, where appropriate, teachers should provide

    students with the opportunities to design their own experiments.This involves students drawing up plans as to how to co nductexperiments, how to measure and analyse data, and how topresent the outcomes of their experiment.

    Discussion

    A discussion is an activity in which students exchange questionsand opinions based on valid reasons. Discussions can beconducted before, during orafter an activity. Teachers should playthe role of a facilitator and lead a discussion by asking questions

    that stimulate thinking and getting students to express themselves.

    Simulation

    In simulation, an activity that resembles the actu al situation iscarried out . Examples of simulation are role-play, games and theuse of models. In role -play, students play out a particular rolebased on certain pre -determined conditions. Games requireprocedures that need to be followed. Students play g amesin orderto learn a particular principle or to understand the process ofdecision-making. Models are used to represent objects or actual

    situations so that students can visualise the said objects orsituations and thus understand the concepts and prin ciples to belearned.

    Project

    A project is a learning activity that is generally undertaken by anindividual or a group of students to achieve a certain learningobjective. A project generally requires several lessons to complete.The outcome of the project either in the form of a report, anartefact or in other forms needs to be presented to the teacher andother students. Project work promotes the development ofproblem-solving skills, time management skills, and independentlearning.

    Visits and Use of External Resources

    The learning of science is not limited to activities carried out in theschool compound. Learning of science can be enhanced throughthe use of external resources such as zoos, museums, sciencecentres, research institutes, mangro ve swamps, and factories.

    Visits to these places make the learning of science more interesting, meaningful and effective. To optimise learningopportunities, visits need to be carefully planned. Students may beinvolved in the planning process and specific educational tasksshould be assigned during the visit. No educational visit iscomplete without a post -visit discussion.

    Use of Technology

    Technology is a powerful tool that has great potential in enhancing

    the learning of science. Through the use o f technology such astelevision, radio, video, computer, and Internet, the teaching andlearning of science can be made more interesting and effective.Computer simulation and animation are effective tools for theteaching and learning of abstract or diffi cult science concepts.Computer simulation and animation can be presented throughcourseware or Web page. Application tools such, as wordprocessors, graphic presentation software and electronicspreadsheets are valuable tools for the analysis and present ationof data.The use of other tools such as data loggers and computerinterfacing in experiments and projects also enhance the

    effectiveness of teaching and learning of science .

    CONTENT ORGANISATION

    The science curriculum is organised around th emes. Each themeconsists of various learning areas, each of which consists of anumber of learning objectives. A learning objective has one ormore learning outcomes.

    Learning outcomes are written based on the hierarchy of thecognitive and affective domains. Levels in the cognitive domainare: knowledge, understanding, application, analysis, synthesisand evaluation. Levels in the affective domain are: to be aware of,to be in awe, to be appreciative, to be thankful, to love, to practise,and to internalise. Where possible, learning outcomes relating tothe affective domain are explicitly stated. The inculcation ofscientific attitudes and noble values should be integrated intoevery learning activity. This ensures a more spontaneous and

    natural inculcation of attitudes and values. Learning areas in thepsychomotor domain are implicit in the learning activities.

    Learning outcomes are written in the form of measurablebehavioural terms. In general, the learning outcomes for aparticular learning object ive are organised in order of complexity.However, in the process of teaching and learning, learningactivities should be planned in a holistic and integrated mannerthat enables the achievement of multiple learning outcomesaccording to needs and context. Teachers should avoid employinga teaching strategy that tries to achieve each learning outcomeseparately according to the order stated in the curriculum
