对教材进行解读研究是每个小学数学教师必备的基本能力。然而,这方面有两个常见问题:一是过于依赖教材,忽视学生的实际需要,将教材的内容照搬进课堂。在“统计”和“量的计量”等知识教学中,这样的问题尤为突出,其结果使得课堂教学单薄无力;二是过多地偏离教材。围绕教学问题随意删减教材中的朴素内容,这类问题主要存在于公开 Interpretation of teaching materials research is essential for every primary school mathematics teachers ability. However, there are two common problems in this regard. One is over-reliance on teaching materials, the neglect of students’ actual needs, and the copying of teaching materials into the classroom. In the “statistics” and “quantity measurement” and other knowledge teaching, the problem is particularly prominent, the result makes the classroom teaching thin and weak; the second is too much deviation from the textbook. Randomly cut around the teaching problems in the simple textbook content, such problems mainly exist in the open
