Presentation Outline Singapore Education in a Nutshell Singapore Mathematics Curriculum National Tests in Singapore Mathematics Teaching in Singapore Mathematics Teachers & Professional Development Achievements of Singapore Students Questions & Discussion Development & Focus Moulding the Future of the Nation Thomas L. Friedman 2006 The World Is Flat Thomas L. Friedman 2006 The World Is Flat Nurturing Knowledge Workers through Ability-Driven Education Beaton, Mullis, Martin, Gonzalez, Kelly & Smith 1996 The Singapore mathematics curriculum states that “an emphasis on mathematics education will ensure that we have an increasingly competitive workforce to meet the challenges of the 21st century” Schools around the world are forced to move forward if they want to make a difference to the future of their students. Agenda for Action (USA) and Cockcroft Report (UK) led to the introduction of a problem-solving curriculum in 1992. Singapore Mathematics Curriculum Framework Beliefs Interest Appreciation Confidence Perseverance Numerical calculation Algebraic manipulation Spatial visualization Data analysis Measurement Use of mathematical tools Estimation Monitoring of one’s own thinking Self-regulation of learning Mathematical Problem Solving Concepts Numerical Algebraic Geometrical Statistical Probabilistic Analytical Reasoning, communication & connections Thinking skills & heuristics Application & modelling This initiative was introduced in 1997. It focuses on explicit teaching of thinking through school subjects. It was revised in 2001 to give more emphasis on a range of heuristics. This initiative was introduced in 2003. It focuses on inculcating good habits of minds amongst students. This call was made in 2004 to encourage the development of strong foundation knowledge.

This call has been made since 2005. Every child should be developed to maximize their potential using different approaches. Technological advances have compelled educators to re-consider what is considered significant in school curriculum. Kaput, Noss & Hoyles 2002 It was revised in 2007 for this reason. It places greater emphasis on visualization and number sense. With the introduction of calculator, mental strategies are also emphasized. PSLE: Emphasis on Visualization The figure below is made up of 2 identical squares, 4 identical rectangles and 3 identical semi-circles. What is the area of the figure? 70 cm PSLE: Emphasis on Number Sense Each of the three cards shown is printed with a different whole number. The smallest number is 23. When these numbers are added two at a time, the sums are 61, 71 and 86. What is the largest number on the cards? 23 It is recognized that mathematics is “an excellent vehicle for the development and improvement of a person’s intellectual competence in logical reasoning, spatial visualization, analysis and abstract thought” Ministry of Education Singapore 2006 Emphasis on Basics & Problem Solving National Tests in Singapore Grade 6 Primary School Leaving Examination PSLE Has always been under the control of Singapore Ministry of Education Singapore Examinations and Assessment Board (SEAB) was set up recently to handle national tests in Singapore Grade 10 GCE Ordinary Level Has always been offered by Cambridge Examination Syndicate until 2008.

Problem Solving for High-Achievers Grade 10 A fly, F, starts at the point with the position vector (i +12j) cm and crawls across the surface with a velocity of (3i + 2j) cm s-1. At the instant that the fly starts crawling, a spider, S, at the point with position vector (85i + 5j) cm, sets off across the surface with a velocity (-5i +kj) cm s-1, where k is a constant. Given that the spider catches the fly, calculate the value of k. Students are expected to make sense and interpret the mathematics they perform. Features of SingaporeMath The use of appropriate manipulatives. These are common manipulatives that have inexpensive alternatives Focus on key concept – what it is, and what it is not Definitions are developed through induction, starting in an informal fashion Opportunities to make connections to previously taught concept - half Mathematical terms are explained. Designed for learners of English language … .. providing other learning opportunities for learners fluent in the language Opportunities for immediate formative assessment Teachers know the content that they are assessing. Teachers have opportunities to learn content knowledge. The program was designed for teachers who do not necessarily have strong mathematics background. Opportunities for the majority to reach proficient level … .. opportunities to engage advanced learners Provides independent practice Provides opportunities for student-constructed responses Practice for the key concept Comparing Areas (Biggest) Even as a new concept is introduced … .. learners are given practice on recently-learnt materials Comparing Areas (Smallest & Greatest) Comparing Areas (Same Size) Building upon previously developed concepts Non-standard unit Standard unit Concrete Pictorial Abstract Opportunities to develop abstract ideas Providing challenging materials for advanced learners while the rest reach a level of mastery for basic materials Non-standard unit Standard unit Focus on key concept – what it is, what it is not Many opportunities to learn More formal definitions are provided if appropriate Students are finding area of figures (previously learnt content) even as they find the perimeters (new content) Opportunities to help struggling students to reach mastery Opportunities for proficient students to not develop common misconceptions, e.g. confusion between area and perimeter Opportunities for advanced students to make new connections A collection of tasks is usually not a random but purposeful collection Opportunities to help struggling students to reach mastery Visuals are prevalent in mathematics eaching and learning in Singapore textbooks.
