- PublicationOpen AccessReading mathematicsSteen (1999) stated that 'quantitative literacy - or numeracy, as it is known in British English - means different things to different people'. He then proposed that quantitative literacy is both more than and different from mathematics - at least as mathematics has traditionally been viewed by school and society.

;Dindyal, Jaguthsing; ;Quek, Khiok Seng; In this paper, we discuss the development of a very specific problem solving curriculum in an independent school in Singapore as part of the first phase of our research project. We are using a design research methodology to fine-tune the problem solving curriculum in which we are introducing the mathematics practical, an idea borrowed from science education.106 196 - PublicationOpen AccessMathematical problem solving for everyone: Infusion and diffusion (MInD)(Office of Education Research, National Institute of Education, Singapore, 2020)
; ; ; ;Quek, Khiok Seng; ;Dindyal, JaguthsingHo, Foo HimThis research project is an attempt to realise the ideals of mathematical problem solving, which is at the heart of the Singapore mathematics curriculum in the daily practices of mainstream mathematics classrooms. This work builds on the foundation of M-ProSE (OER 32/08 TTL) to diffuse the findings to the mainstream school curriculum. Our work involves three steps: (1) initialisation of problem solving as an essential part of the mathematics curriculum in a school at the foundational year; (2) infusion of problem solving as an embedded regular curricular and pedagogical practice across all year levels in the school, and (3) diffusion of this innovation from this school to the full range of schools in Singapore. In each of the above steps, we take a complex systems approach and include curriculum, instructional practices, assessment and teacher professional development in our overall design research process. Our current project builds upon the initial foundation of MProSE to scale out (infuse) and scale up (diffuse) the innovation to mainstream schools in Singapore, hence the project is named MInD. With the experience and data collected from MProSE research school, the design needs to be re-adjusted in order for problem solving to be diffused throughout the mainstream schools. The importance and relevance of this research project to schools is readily observed by the schools' responses: To the researchers' pleasant surprise, four mainstream schools readily expressed their commitment to participate in this research as the school leaders see the relevance of this project to their school curriculum. Further, the Principal of MProSE research school expressed his interest to get his school involved for the infusion phase(step (2)) of the research. The research team of MInD consists of the original researchers from MProSE and two more new team members. The entire team consists of expertise from different fields: mathematicians, mathematics educator, educational psychologist, curriculum specialist, senior teacher, a school principal (who is also a mathematician), an expert of change management and leadership studies, a senior MOE curriculum specialist.168 90 - PublicationOpen AccessTangrams: On attention and errorEven in mathematics, a lack of attention may result in a publication with errors. This article postulates a reason why errors are made in mathematics and their consequences. The discussion revolves around the possibility of using certain numbers of Tangram sets to form squares of sides of different lengths. Implications for pedagogy are drawn to avoid and to capitalise on errors.
77 146 - PublicationOpen AccessOptimal orientations of vertex-multiplications of Cartesian products of graphsKoh and Tay proved a fundamental classification of G vertex-multiplications into three classes C0, C1 and C2. In this paper, we prove that vertex-multiplications of Cartesian products of graphs G × H lie in C0 (respectively, C0∪C1) if G(2) ∈ C0 (respectively, C1), d(G) ≥ 2 and d(G×H) ≥ 4, providing further support for a conjecture by Koh and Tay. We also focus on Cartesian products involving trees, paths and cycles and show that most of them lie in C0.
64 104 - PublicationOpen AccessInfusing problem solving into mathematics content course for pre-service secondary school mathematics teachers(Association of Mathematics Educators, 2013)
; ;Quek, Khiok Seng; ; ; ;Ho, Foo HimDindyal, JaguthsingThis paper presents a re-design of an undergraduate mathematics content course on Introductory Differential Equations for pre-service secondary school mathematics teachers. Based on the science practical paradigm, mathematics practical lessons emphasizing problem-solving processes via the undergraduate content knowledge were embedded within the curriculum delivered through the traditional lecture-tutorial system. The pre-service teachers' performance in six mathematics practical lessons and the mathematics practical test was examined. They were able to respond to the requirements of the mathematics practical to go through the entire process of problem solving and to carry out "Look Back" at their solution: checking the correctness of their solution, offering alternative solutions, and expanding on the given problem. The use of Mathematics Practical has altered the pre-service teachers’ approach in tackling mathematics problems in a positive direction.235 593 - PublicationOpen AccessA study of school mathematics curriculum enacted by competent teachers in Singapore secondary schools(National Institute of Education (Singapore), 2017)
; ; ; ; 70 178 - PublicationOpen AccessPreparing mathematics teachers in Singapore: The issue of mathematics content knowledgeLee Shulman (1986) brought to the forefront the need to distinguish the different dimensions of teacher knowledge that will help guide teacher preparation. Instead of the then prevalent view of ensuring that the student teacher enters teacher education with adequate subject content knowledge and then equipping her with generic pedagogical knowledge, Shulman introduced the dimension at the nexus of subject content knowledge and generic pedagogical knowledge as pedagogical content knowledge. We, as Mathematics educators, are happy to claim Shulman as one of our own, as he based much of his research and writing on the discipline of Mathematics.

; ; ; ;Quek, Khiok SengYap, Romina Ann SoonWe recognize that though teachers may participate in various forms of professional development (PD) programmes, learning that they may have gained in the PD may not always lead to corresponding perceivable changes in their classroom teaching. We offer a theoretical re-orientation towards this issue by introducing a construct we term “concretisation”. Concretisations are resources developed in PD settings which can be converted into tangible tools for classroom use. In theorising such resources, we contribute in informing the design process of teacher professional development for better impact into actual classroom practice. We purport principles of design which render concretisations effective. Subsequently, we test these principles by presenting a specific case of teaching mathematical problem solving.WOS© Citations 4Scopus© Citations 3 151 279
