Using performance assessment in secondary school mathematics: an empirical study in a Singapore classroom
No full textThis article reports an exploratory study on using performance assessment in mathematics instruction in a high-performing secondary school in Singapore. An intact mathematics class participated in the study, and received chapter-based performance tasks as intervention during regular mathematics lessons for about one and a half school years. The performance tasks used included authentic and/or open-ended tasks. The students’ academic achievements and attitudes in mathematics were compared with a comparison class that did not receive the intervention. Both quantitative and qualitative data were collected, mainly through questionnaire surveys, performance task tests, conventional school exams, and interviews with students and teachers. The results suggest that the students receiving the intervention performed significantly better than their counterparts in solving conventional exam problems, and in general they also showed more positive changes in attitudes towards mathematics and mathematics learning. The students from the experimental class also expressed positive views about the benefits of using performance tasks in promoting their ability in higher order thinking, though no statistically significant difference was detected between the two classes of students in solving unconventional tasks before and after intervention. Overall, the results appear to support teachers’ using contextualised problems in real life situations and open-ended investigations in students’ learning of mathematic

Problem solving in Singaporean secondary mathematics textbooks
No full textThis study examined how two widely used Singapore school mathematics textbooks at lower secondary level represent problem solving. The study established a framework on the classification of problems and problem solving procedures to code and analyze the from the textbooks. Based on the framework, an overall picture of the representation of problem solving in the textbooks was obtained. The authors concluded that the textbooks present a good foundation for students to development their abilities in problem solving and are strong in aspects such as using fundamental/theoretical knowledge to solve problem, developing students’ logical and higher-order thinking skills through solving multistep and challenging problem, exposing students to a variety of heuristics, and leading students to new concepts and algorithms through problem solving. The authors also suggested some areas for further improvement of the textbooks concerning the representation of solving
Research on Singapore mathematics curriculum and textbooks: searching for reasons behind students’ outstanding performance
No full textOver the last 15 or so years, the Singapore mathematics curriculum and textbooks have attracted a considerable amount of attention internationally,particularly from educational researchers, reformers and policy makers. This phenomenon is closely related to people’s interest in searching for the reasons for Singapore students’ outstanding performances in well referred international comparative studies, such as The Trends in International Mathematics and Science Study (TIMSS) and The Programme for International Student Assessment (PISA). This chapter is intended to provide readers with an overall look at the development of the Singapore mathematics curriculum and textbooks and research that have been carried out over the last decades on these two related areas, and discuss relevant issues concerning mathematics curriculum and textbook development
From convergence to divergence: the development of mathematical problem solving in research, curriculum, and classroom practice in Singapore
No full textFollowing the movement of problem solving in the US and other parts of the world in the 1980s, problem solving became the central focus of Singapore’s national school mathematics curriculum in 1990 and thereafter the key theme in research and practice. Different from some other countries, this situation has largely not changed in Singapore mathematics education since then. However, within the domain of problem solving, mathematics educators in Singapore focused more on the fundamental knowledge, basic skills, and heuristics for problem solving till the mid 1990s. In particular, problem solving heuristics, especially the so-called ‘‘model method’’, a term most widely used for problem solving, received much attention in syllabus, research, and classroom instruction. Since the late 1990s, following the national vision of ‘‘Thinking Schools, Learning Nation’’ and nurturing modern citizens with independent, critical, and creative thinking, Singapore mathematics educators’ attention has greatly expanded to the development of students’ higher-order thinking, selfreflection and self-regulation, alternative ways of assessment and instruction, among other aspects concerning problem solving. Researchers have also looked into the advantages and disadvantages of Singapore’s textbooks in representing problem solving, and the findings of these investigations have influenced the development of the latest school mathematics textboo
