Leong, Yew Hoong; Cheng, Lu Pien; Toh, Wei Yeng Karen; Kaur, Berinderjeet; Toh, Tin Lam – Mathematics Education Research Journal, 2021
It is easy to dismiss the work of "teaching students to apply formula" as a low-order priority and thus trivialises the professional knowledge associated with this practice. Our encounter with an experienced teacher--through the examination of her practices and elaborations--challenges this simplistic assumption. There are layers of…

Leong, Yew Hoong; Toh, Tin Lam; Tay, Eng Guan; Quek, Khiok Seng; Toh, Pee Choon; Jaguthsing, Dindyal – International Journal of Science and Mathematics Education, 2021
The more ambitious an educational innovation, the greater the challenge in scaling up. In this paper, we focus on the scaling up of an ambitious pedagogical practice--mathematics problem solving as a regular feature in the classroom. We adopt a long-term approach to continual professional development (CPD) that began with intensive work with one…
