作者指出，很多人認為在普及教育政策下，學生唸不好數學是因為數學課程太深，內容太多，只要教淺一些，少一些，問題便可解決。故作者提出一套另類的想法，就是把數學課變得更富數學味道，務求以數學的內在美誘發學生的學習動機。

Background This study examined the effects of different approaches to teaching learners with mild intellectual disabilities to solve mathematical word problems. Method Thirty Chinese students with mild intellectual disabilities from a special school in Hong Kong were taught using conventional instruction, worked example instruction, and cognitive strategy instruction. A cross‐subjects experimental design was used to compare the effects of the three instructional approaches on immediate and delayed tests. Results Students presented with worked example and cognitive strategy instruction solved more problems correctly and generally outperformed students presented with conventional instruction in both immediate and delayed tests. In addition, learners receiving worked example and cognitive strategy instruction were more able to maintain and generalise their previous knowledge and skills to solve novel problems than those receiving conventional instruction. Conclusions The findings indicate that learners can profit from worked example and cognitive strategy instruction which can promote problem‐solving skills and mathematical learning.

Structural equation models linking cognitive and affective factors, approach to learning, and perceptions of the actual and preferred mathematics classroom environments were tested in a longitudinal study involving 356 secondary school students in Hong Kong. Models of acceptable fit that clarified the effects of classroom environment on how students learn and the outcomes they achieve were obtained. Numerous significant paths from prior learning experience to environmental variables were identified; the most salient path from classroom environment to learning outcomes was that between an enjoyable classroom environment and cognitive achievement. An enjoyable classroom environment mediated the causal relationship between a deep approach and high-level achievement. However, classroom environment did not seem to influence changes in approach to learning.
