数学课堂教学既要遵循教学活动的一般规律,又要遵循数学活动的特殊规律,是“教与学对应”和“教与数学对应”的双逻辑建构。任何一个对应处理不好都不可能产生好的教学效果。所谓数学课堂的学科缺失,简单讲就是课堂教学与“数学”的不对应,即课堂教学的内容、认知、活动、表达等方面不 Mathematics classroom teaching should not only follow the general rules of teaching activities, but also follow the special rules of mathematics activities. It is a dual logical construction of “teaching and learning correspondence” and “correspondence between teaching and mathematics”. It is impossible to produce good teaching effect if any one of the corresponding processing is not good. The lack of discipline in the so-called mathematics classroom is simply not the correspondence between classroom instruction and “math”, that is, the content, cognition, activities, and expressions of classroom teaching are not
