(v)Education in Malaysia is an ongoing efforttowards further developing the potential ofindividuals in a holistic and integratedmanner so as to produce individuals who areintellectually, spiritually, emotionally andphysically balanced and harmonious, basedon a firm belief in God. Such an effort isdesigned to produce Malaysian citizens whoare knowledgeable and competent, whopossess high moral standards, and who areresponsible and capable of achieving a highlevel of personal well-being as well as beingable to contribute to the betterment of thefamily, the society and the nation at large.
(vii)PREFACEScience and technology plays a critical role in realising Malaysia’saspiration to become a developed nation. Since mathematics is instrumentalin the development of scientific and technological knowledge, the provisionof quality mathematics education from an early age in the education processis thus important. The Malaysian school curriculum offers threemathematics education programs, namely Mathematics for primary schools,Mathematics and Additional Mathematics for secondary schools.The Malaysian school mathematics curriculum aims to developmathematical knowledge, competency and inculcate positive attitudestowards mathematics among pupils. Mathematics for secondary schoolsprovides opportunities for pupils to acquire mathematical knowledge andskills, and develop higher order problem solving and decision making skillsto enable pupils to cope with daily life challenges. As with other subjects inthe secondary school curriculum, Mathematics aims to inculcate noblevalues and love for the nation in the development of a holistic person, whoin turn will be able to contribute to the harmony and prosperity of the nationand its people.Beginning 2003, English is used as the medium of instruction for Scienceand Mathematics subjects. The policy to change the medium of instructionfor Science and Mathematics subjects follows a phased implementationschedule and is expected to be completed by 2008.In the teaching and learning of Mathematics, the use of technologyespecially ICT is greatly emphasised. Mathematics taught in English,coupled with the use of ICT, provide greater opportunities for pupils toimprove their knowledge and skills in mathematics because of the richnessof resources and repositories of knowledge in English. Pupils will be betterable to interact with pupils from other countries, improve their proficiencyin English and thus make the learning of mathematics more interesting andexciting.The development of this Mathematics syllabus is the work of manyindividuals and experts in the field. On behalf of the CurriculumDevelopment Centre, I would like to express much gratitude andappreciation to those who have contributed in one way or another towardsthis initiative(MAHZAN BIN BAKAR SMP, AMP)DirectorCurriculum Development CentreMinistry of EducationMalaysia
(ix)INTRODUCTIONA well-informed and knowledgeable society well versed in the use ofmathematics to cope with daily life challenges is integral to realising thenation’s aspiration to become an industrialised nation. Thus, efforts are takento ensure a society that assimilates mathematics into their daily lives. Pupilsare nurtured from an early age with the skills to solve problems andcommunicate mathematically, to enable them to make effective decisions.Mathematics is essential in preparing a workforce capable of meeting thedemands of a progressive nation. As such, this field assumes its role as thedriving force behind various developments in science and technology. In linewith the nation’s objective to create a knowledge-based economy, the skillsof Research & Development in mathematics is nurtured and developed atschool level.As a field of study, Mathematics trains the mind to think logically andsystematically in solving problems and making decisions. This disciplineencourages meaningful learning and challenges the mind, and hencecontributes to the holistic development of the individual. To this end,strategies to solve problems are widely used in the teaching and learning ofmathematics. The development of mathematical reasoning is believed to beclosely linked to the intellectual development and communication ability ofpupils. Hence, mathematics reasoning skills are also incorporated in themathematics activities to enable pupils to recognize, build and evaluatemathematics conjectures and statements.In keeping with the National Education Philosophy, the Mathematicscurriculum provides opportunities to pupils from various backgrounds andlevels of abilities to acquire mathematical skills and knowledge. Pupils arethen able to seek relevant information, and be creative in formulatingalternatives and solutions when faced with challenges.The general Mathematics curriculum has often been seen to comprise ofdiscrete areas related to counting, measurement, geometry, algebra andsolving problems. To avoid the areas to be continually seen as separate andpupils acquiring concepts and skills in isolation, mathematics is linked toeveryday life and experiences in and out of school. Pupils will have theopportunity to apply mathematics in different contexts, and see the relevanceof mathematics in daily life.In giving opinions and solving problems either orally or in writing, pupilsare guided in the correct usage of language and mathematics registers. Pupilsare trained to select information presented in mathematical and non-mathematical language; interpret and represent information in tables, graphs,diagrams, equations or inequalities; and subsequently present informationclearly and precisely, without any deviation from the original meaning.Technology in education supports the mastery and achievement of thedesired learning outcomes. Technology used in the teaching and learning ofMathematics, for example calculators, are to be regarded as tools to enhancethe teaching and learning process and not to replace teachers.Importance is also placed on the appreciation of the inherent beauty ofmathematics. Acquainting pupils with the life-history of well-knownmathematicians or events, the information of which is easily available fromthe Internet for example, will go a long way in motivating pupils toappreciate mathematics.The intrinsic values of mathematics namely thinking systematically,accurately, thoroughly, diligently and with confidence, infused throughoutthe teaching and learning process; contribute to the moulding of characterand the inculcation of positive attitudes towards mathematics. Together withthese, moral values are also introduced in context throughout the teachingand learning of mathematics.
(x)Assessment, in the form of tests and examinations helps to gauge pupils’achievements. The use of good assessment data from a variety of sourcesalso provides valuable information on the development and progress ofpupils. On-going assessment built into the daily lessons allows theidentification of pupils’ strengths and weaknesses, and effectiveness of theinstructional activities. Information gained from responses to questions,group work results, and homework helps in improving the teaching process,and hence enables the provision of effectively aimed lessons.AIMThe mathematics curriculum for secondary schools aims to developindividuals who are able to think mathematically, and apply mathematicalknowledge effectively and responsibly in solving problems and makingdecisions; and face the challenges in everyday life brought about by theadvancement of science and technology.OBJECTIVESThe mathematics curriculum for the secondary school enables pupils to:1 understand definitions, concepts, laws, principles, and theorems related toNumber, Shape and Space, and Relationship;2 widen the use of basic operations of addition, subtraction, multiplicationand division related to Number, Shape and Space, and Relationship;3 acquire basic mathematical skills such as:• making estimation and rounding;• measuring and constructing;• collecting and handling data;• representing and interpreting data;• recognising and representing relationship mathematically;• using algorithm and relationship;• solving problems; and• making decisions.4 communicate mathematically;5 apply knowledge and skills of mathematics in solving problems andmaking decisions;6 relate mathematics with other areas of knowledge;7 use suitable technologies in concept building, acquiring skills, solvingproblems and exploring the field of mathematics;8 acquire mathematical knowledge and develop skills effectively and usethem responsibly;9 inculcate a positive attitude towards mathematics; and10 appreciate the importance and beauty of mathematics.CONTENT ORGANISATIONThe Mathematics Curriculum content at the secondary school level isorganised into three main areas, namely: Number; Shape and Space; andRelationship. Mathematical concepts related to the respective area, arefurther organised into topics. These topics are arranged in a hierarchicalmanner such that the more basic and tangible concepts appear first and themore complex and abstract concepts appear subsequently.
(xi)The Learning Area outlines the scope of mathematical knowledge, abilitiesand attitudes to be developed in pupils when learning the subject. They aredeveloped according to the appropriate learning objectives and representedin five columns, as follows:Column 1: Learning ObjectivesColumn 2: Suggested Teaching and Learning ActivitiesColumn 3: Learning OutcomesColumn 4: Points To Note; andColumn 5: Vocabulary.The Learning Objectives define clearly what should be taught. They coverall aspects of the Mathematics curriculum programme and are presented in adevelopmental sequence designed to support pupils understanding of theconcepts and skill of mathematics.The Suggested Teaching and Learning Activities lists some examples ofteaching and learning activities including methods, techniques, strategies andresources pertaining to the specific concepts or skills. These are, however,not the only intended approaches to be used in the classrooms. Teachers areencouraged to look for other examples, determine teaching and learningstrategies most suitable for their students and provide appropriate teachingand learning materials. Teachers should also make cross-references to otherresources such as the textbooks and the Internet.The Learning Outcomes define specifically what pupils should be able todo. They prescribe the knowledge, skills or mathematical processes andvalues that should be inculcated and developed at the appropriate level.These behavioural objectives are measurable in all aspects.In the Points To Note column, attention is drawn to the more significantaspects of mathematical concepts and skills. These emphases are to be takeninto account so as to ensure that the concepts and skills are taught and learnteffectively as intended.The Vocabulary consists of standard mathematical terms, instructionalwords or phrases which are relevant in structuring activities, in askingquestions or setting tasks. It is important to pay careful attention to the use ofcorrect terminology and these need to be systematically introduced to pupilsin various contexts so as to enable them to understand their meaning andlearn to use them appropriately.EMPHASES IN TEACHING AND LEARNINGThis Mathematics Curriculum is arranged in such a way so as to giveflexibility to teachers to implement an enjoyable, meaningful, useful andchallenging teaching and learning environment. At the same time, it isimportant to ensure that pupils show progression in acquiring themathematical concepts and skills.In determining the change to another learning area or topic, the followinghave to be taken into consideration:• The skills or concepts to be acquired in the learning area or incertain topics;• Ensuring the hierarchy or relationship between learning areas ortopics has been followed accordingly; and• Ensuring the basic learning areas have been acquired fully beforeprogressing to more abstract areas.The teaching and learning processes emphasise concept building and skillacquisition as well as the inculcation of good and positive values. Besidesthese, there are other elements that have to be taken into account and infusedin the teaching and learning processes in the classroom. The main elementsfocused in the teaching and learning of mathematics are as follows:
(xii)1. Problem Solving in MathematicsProblem solving is the main focus in the teaching and learning ofmathematics. Therefore the teaching and learning process must includeproblem solving skills which are comprehensive and cover the wholecurriculum. The development of problem solving skills need to beemphasised so that pupils are able to solve various problems effectively. Theskills involved are:• Understanding the problem;• Devising a plan;• Carrying out the plan; and• Looking back at the solutions.Various strategies and steps are used to solve problems and these areexpanded so as to be applicable in other learning areas. Through theseactivities, students can apply their conceptual understanding of mathematicsand be confident when facing new or complex situations. Among theproblem solving strategies that could be introduced are:• Trying a simple case;• Trial and improvement;• Drawing diagrams;• Identifying patterns;• Making a table, chart or systematic list;• Simulation;• Using analogies;• Working backwards;• Logical reasoning; and• Using algebra.2. Communication in MathematicsCommunication is an essential means of sharing ideas and clarifying theunderstanding of Mathematics. Through communication, mathematical ideasbecome the object of reflection, discussion and modification. The process ofanalytical and systematic reasoning helps pupils to reinforce and strengthentheir knowledge and understanding of mathematics to a deeper level.Through effective communication, pupils will become efficient in problemsolving and be able to explain their conceptual understanding andmathematical skills to their peers and teachers.Pupils who have developed the skills to communicate mathematically willbecome more inquisitive and, in the process, gain confidence.Communication skills in mathematics include reading and understandingproblems, interpreting diagrams and graphs, using correct and concisemathematical terms during oral presentations and in writing. The skillsshould be expanded to include listening.Communication in mathematics through the listening process occurs whenindividuals respond to what they hear and this encourages individuals tothink using their mathematical knowledge in making decisions.Communication in mathematics through the reading process takes placewhen an individual collects information and data and rearranges therelationship between ideas and concepts.Communication in mathematics through the visualisation process takes placewhen an individual makes an observation, analyses, interprets andsynthesises data and presents them in the form of geometric board, picturesand diagrams, tables and graphs. An effective communication environmentcan be created by taking into consideration the following methods:• Identifying relevant contexts associated with environment andeveryday life experience of pupils;• Identifying pupils’ interests;
(xiii)• Identifying suitable teaching materials;• Ensuring active learning;• Stimulating meta-cognitive skills;• Inculcating positive attitudes; and• Setting up conducive learning environment.Effective communication can be developed through the following methods:Oral communication is an interactive process that involves psychomotoractivities like listening, touching, observing, tasting and smelling. It is a two-way interaction that takes place between teacher and pupils, pupils andpupils, and pupils and object.Some of the more effective and meaningful oral communication techniquesin the learning of mathematics are as follows:• Story-telling and question and answer sessions using one’s ownwords;• Asking and answering questions;• Structured and unstructured interviews;• Discussions during forums, seminars, debates and brainstormingsessions; and• Presentation of findings of assignments.Written communication is the process whereby mathematical ideas andinformation are disseminated through writing. The written work is usuallythe result of discussion, input from people and brainstorming activities whenworking on assignments. Through writing, pupils will be encouraged tothink in depth about the mathematics content and observe the relationshipsbetween concepts. Examples of written communication activities that can bedeveloped through assignments are:• Doing exercises;• Keeping journals;• Keeping scrap books;• Keeping folios;• Keeping portfolios;• Undertaking projects; and• Doing written tests.Representation is a process of analysing a mathematical problem andinterpreting it from one mode to another. Mathematical representationenables pupils to find relationships between mathematical ideas that areinformal, intuitive and abstract using everyday language. For example 6xycan be interpreted as a rectangular area with sides 2x and 3y. This will makepupils realise that some methods of representation are more effective anduseful if they know how to use the elements of mathematical representation.3. Reasoning in MathematicsLogical Reasoning or thinking is the basis for understanding and solvingmathematical problems. The development of mathematical reasoning isclosely related to the intellectual and communicative development of pupils.Emphasis on logical thinking, during mathematical activities opens uppupils’ minds to accept mathematics as a powerful tool in the world today.Pupils are encouraged to estimate, predict and make intelligent guesses inthe process of seeking solutions. Pupils at all levels have to be trained toinvestigate their predictions or guesses by using concrete material,calculators, computers, mathematical representation and others. Logicalreasoning has to be absorbed in the teaching of mathematics so that pupilscan recognise, construct and evaluate predictions and mathematicalarguments.
(xiv)4. Mathematical ConnectionsIn the mathematics curriculum, opportunities for making connections mustbe created so that pupils can link conceptual to procedural knowledge andrelate topics within mathematics and other learning areas in general.The mathematics curriculum consists of several areas such as arithmetic,geometry, algebra, measures and problem solving. Without connectionsbetween these areas, pupils will have to learn and memorise too manyconcepts and skills separately. By making connections, pupils are able to seemathematics as an integrated whole rather than a jumble of unconnectedideas. When mathematical ideas and the curriculum are connected to real lifewithin or outside the classroom, pupils will become more conscious of theimportance and significance of mathematics. They will also be able to usemathematics contextually in different learning areas and in real lifesituations.5. Application of TechnologyThe teaching and learning of mathematics should employ the latesttechnology to help pupils understand mathematical concepts in depth,meaningfully and precisely and enable them to explore mathematical ideas.The use of calculators, computers, educational software, websites in theInternet and relevant learning packages can help to upgrade the pedagogicalapproach and thus promote the understanding of mathematical concepts.The use of these teaching resources will also help pupils absorb abstractideas, be creative, feel confident and be able to work independently or ingroups. Most of these resources are designed for self-access learning.Through self-access learning pupils will be able to access knowledge orskills and informations independently according to their own pace. This willserve to stimulate pupils interests and develop a sense of responsibilitytowards their learning and understanding of mathematics.Technology however does not replace the need for all pupils to learn andmaster the basic mathematical skills. Pupils must be able to efficiently add,subtract, multiply and divide without the use of calculators or otherelectronic tools. The use of technology must therefore emphasise theacquisition of mathematical concepts and knowledge rather than merelydoing calculation.APPROACHES IN TEACHING AND LEARNINGThe belief on how mathematics is learnt influence how mathematicalconcepts are to be taught. Whatever belief the teachers subscribe to, the factremains that mathematical concepts are abstract. The use of teachingresources is therefore crucial in guiding pupils to develop matematical ideas.Teachers should use real or concrete materials to help pupils gainexperience, construct abstract ideas, make inventions, build self confidence,encourage independence and inculcate the spirit of cooperation.The teaching and learning materials used should contain self diagnosticelements so that pupils know how far they have understood the concepts andacquire the skills.In order to assist pupils in having positive attitudes and personalities, theintrinsic mathematical values of accuracy, confidence and thinkingsystematically have to be infused into the teaching and learning process.Good moral values can be cultivated through suitable contexts. Learning ingroups for example can help pupils to develop social skills, encouragecooperation and build self confidence. The element of patriotism should alsobe inculcated through the teaching and learning process in the classroomusing certain topics.
(xv)Brief historical anecdotes related to aspects of mathematics and famousmathematicians associated with the learning areas are also incorporated intothe curriculum. It should be presented at appropriate points where it providesstudents with a better understanding and appreciation of mathematics.Various teaching strategies and approaches such as direct instruction,discovery learning, investigation, guided discovery or other methods must beincorporated. Amongst the approaches that can be given considerationinclude the following:• Pupils-centered learning that is interesting;• Different learning abilities and styles of pupils;• Usage of relevant, suitable and effective teaching materials; and• Formative evaluation to determine the effectiveness of teaching andlearning.The choice of an approach that is suitable will stimulate the teaching andlearning environment inside or outside the classroom. Approaches that areconsidered suitable include the following:• Cooperative learning;• Contextual learning;• Mastery learning;• Constructivism;• Enquiry-discovery; and• Future studies.EVALUATIONEvaluation or assessment is part of the teaching and learning process toascertain the strengths and weaknesses of pupils. It has to be planned andcarried out as part of the classroom activities. Different methods ofassessment can be conducted. These maybe in the form of assignments, oralquestioning and answering, observations and interviews. Based on theresponse, teachers can rectify pupils misconceptions and weaknesses andalso improve their own teaching skills. Teachers can then take subsequenteffective measures in conducting remedial and enrichment activities inupgrading pupils’ performances.
