INTRODUCTION

The Ministry of Education’s vision of “Thinking School, Learning Nation” gives impetus forthe infusion of three initiatives: Thinking Skills, Information Technology (IT) and NationalEducation into the curriculum. As we move towards a knowledge-based society that ispowered by IT, the need to prepare our people for the challenges and opportunities of thefuture becomes obvious. Besides being proficient in the use of IT, pupils will need to be ableto think creatively, learn independently and work successfully in teams. Above all, asSingapore’s economy moves towards globalisation, they need to have a strong feeling forhome and remain Singaporean in heart, mind and being. Against this background and withthe Desired Outcomes of Education as the overarching aim, the mathematics syllabus wasrevised.

This revised mathematics syllabus better reflects the recent developments in mathematicseducation. The focus of the syllabus is mathematical problem solving. The emphasis is onthe development of concepts, skills and its underlying processes. This, together with theexplication of thinking skills and the integration of IT in mathematics teaching and learning,will give leverage to the development of mathematical problem solving.

This syllabus consists of two parts.

Part A explains the philosophy of the syllabus and the spirit in which it should beimplemented. It also spells out the objectives of the mathematics programme.

The framework of the mathematics programme summarises the essence of mathematicsteaching and learning in schools. The learning of mathematics at all levels involves morethan the basic acquisition of concepts and skills. It also involves an understanding of themathematical thinking and general problem-solving strategies, having positive attitudes toand an appreciation of mathematics as an important and powerful tool in everyday life. Thisframework forms the basis for mathematics teaching and learning in schools.

Part B gives the syllabus content for each level. Care has been taken to ensure that there iscontinuity from the primary to the secondary level. In the syllabus, the spiral approach isadopted to ensure that each topic is covered at appropriate levels in increasing depth toenable pupils to consolidate the concepts and skills learnt and to further develop them. Alltopics come with ‘Learning Outcomes’ to enable teachers to monitor pupils' progress. The‘Remarks’ column provides teachers with guidance in interpreting the syllabus.

This syllabus is a guide for teachers to plan their mathematics programmes. Teachers neednot be bound by the sequence of topics presented here but should ensure that the hierarchyand linkages are maintained. Teachers should exercise flexibility and creativity when usingthe syllabus.

• acquire and apply the skills and knowledge relating to number, measure and space inmathematical situations that they will meet in life.

• acquire mathematical concepts and skills necessary for a further study in mathematicsor other disciplines.

• develop the ability to make logical deduction and induction as well as to explicate theirthinking and reasoning skills through the solving of mathematical problems.

• use mathematical language to communicate mathematical ideas and argumentsprecisely, concisely and logically.

• develop positive attitudes towards mathematics including confidence, enjoyment andperseverance.

• appreciate the power and structure of mathematics, including patterns and relationships,and to enhance their intellectual curiosity.

FRAMEWORK OF THE MATHEMATICS PROGRAMME

The conceptualisation of the mathematics syllabus is based on the following framework:

AppreciationInterest Monitoring one’sConfidence own thinkingPerseverance

Estimation andApproximationMental calculation Thinking skillsCommunication HeuristicsUse of mathematical toolsArithmetic manipulationAlgebraic manipulationHandling data Numerical

Geometrical Algebraic Statistical

The primary aim of the mathematics programme is to enable pupils to develop their ability inmathematical problem solving. Mathematical problem solving includes using and applyingmathematics in practical tasks, in real life problems and within mathematics itself. In thiscontext, a problem covers a wide range of situations from routine mathematical problems toproblems in unfamiliar context and open-ended investigations that make use of the relevantmathematics and thinking processes.

The attainment of this mathematical problem solving ability is dependent on five inter-related

components - Concepts, Skills, Processes, Attitudes and Metacognition

1 Concepts

Concepts refer to the basic mathematical knowledge needed for solving mathematical

problems. They cover the following:

•••• Numerical concepts

• Geometrical concepts

• Algebraic concepts

• Statistical concepts

Page 6: LOWER SECONDARY MATHEMATICS SYLLABUSmath.nie.edu.sg/kcang/pgde/docs/ls.pdf · 1 lower secondary mathematics syllabus special/express normal academic normal technical curriculum planning

2 Skills

Skills refer to the topic-related manipulative skills that pupils are expected to use when

solving problems. They include:

• Estimation and approximation

• Mental calculation

• Communication

• Use of mathematical tools

• Arithmetic manipulation

• Algebraic manipulation

• Handling data

3 Processes

Processes refer to the thinking and heuristics involved in mathematical problem solving.

Some thinking skills and heuristics, which are applicable to problem solving at the

secondary level, are listed below.

Thinking skills:

• Classifying

• Comparing

• Identifying Attributes & Components

• Sequencing

• Induction

• Deduction

• Generalising

• Justifying

• Verifying

• Spatial visualisation

Heuristics for problem solving:• Act it out

• Use a diagram/model

• Use guess-and-check

• Make a systematic list

Page 7: LOWER SECONDARY MATHEMATICS SYLLABUSmath.nie.edu.sg/kcang/pgde/docs/ls.pdf · 1 lower secondary mathematics syllabus special/express normal academic normal technical curriculum planning

PART A

7

• Look for pattern(s)

• Work backwards

• Use before-after concept

• Make suppositions

• Restate the problem in another way

• Simplify the problem

• Solve part of the problem

• Think of a related problem

• Use equations

(Refer to Appendix A for the definitions of the suggested thinking skills.)

4 Attitudes

Attitudes refer to the affective aspects of mathematics learning such as:

• enjoying mathematics

• appreciating the beauty and power of mathematics

• showing confidence in using mathematics

• persevering in solving a problem

5 Metacognition

Metacognition refers to the ability to monitor one's own thinking processes in problem

solving. This includes:

•••• constant and conscious monitoring of the strategies and thinking processes used

in carrying out a task

•••• seeking alternative ways of performing a task

•••• checking the appropriateness and reasonableness of answers

This framework encompasses the whole mathematics programme for primary and

secondary schools. The secondary curriculum is a continuation of the primary

curriculum.

GENERAL ASSESSMENT GUIDELINES

Assessment is an integral part of the teaching-learning process. The main purpose ofmathematical assessment should be to improve the teaching and learning of mathematics.Therefore we need assessment that:

• is continual and provides accurate and useful information about pupils’ learning• supports the programme in its aim to enable pupils to develop their problem solving

ability and in its emphasis on developing mathematical concepts, skills and thinking, aswell as positive attitudes towards mathematics

Teachers should assess different aspects of thinking, learning and behaviour. They shouldtry to incorporate, where appropriate, the following aspects in the assessment tasks set asthese are the key features of the syllabus:

• mental calculation• mathematical communication• practical uses of mathematics• investigative work• problem solving• critical thinking• creative work• use of information technology

Continual Assessment

It is important to carry out assessment on a continual basis. Teachers should use continualassessment to:

• obtain information about pupils’ learning, suitability of teaching methods and materialsand effectiveness of the teaching programme

• identify any learning difficulties that pupils may encounter or misconceptions that theymay have so as to plan effective remedial help

• provide prompt feedback to pupils on their progress and attainment• promote pupils’ confidence in doing mathematics by focusing on what they can achieve

rather than what they cannot

In continual assessment, teachers should use a variety of assessment modes as differentmodes provide different kinds of feedback about pupils. The modes used should yield thefeedback required, and collectively, they give teachers a more comprehensive profile of thepupils.

Assessment can be carried out through:

• classroom observations;• oral communication• written assignments and tests• practical and investigative tasks

Page 9: LOWER SECONDARY MATHEMATICS SYLLABUSmath.nie.edu.sg/kcang/pgde/docs/ls.pdf · 1 lower secondary mathematics syllabus special/express normal academic normal technical curriculum planning

PART A

9

From observations of pupils engaged in a task and through their responses in oralcommunication, immediate feedback can be obtained on their understanding of concepts,thinking processes, mastery of skills and even their attitudes towards mathematics. Writtenassignments and tests help teachers to track the progress of pupils and are useful in theassessment of content and procedures, mathematical thinking and problem solving.Through practical and investigative tasks, teachers can assess pupils’ problem solving skills,creative and critical thinking as well as their attitudes. If the tasks are done in groups,teamwork can also be assessed.

Semestral Assessment

Semestral assessment comprises the mid-year and end-of-year examinations, which arecommon school-based examinations administered under formal conditions. The purpose ofsemestral assessment is to determine how far pupils have achieved the overall programmeobjectives for the semester or year. As such, it should be broad in coverage, test arepresentative sample of the syllabus taught and reflect its emphasis.
