很多数学知识是通过数学公式呈现的,获得数学公式的过程应是数学知识生成的过程,学生对数学公式的理解程度决定了其对数学知识的达成度,可惜的是,一些教师不注重数学公式的推导或推导不到位,导致学生在知识的掌握上处于“饥饿”或“吃夹生饭”状态,这对学生的思维发展是极为不利的.教师在教学中应对数学公式的生成给予足够的重 A lot of mathematical knowledge is presented through mathematical formulas. The process of obtaining mathematical formulas should be the process of mathematical knowledge generation. Students’ understanding of mathematical formulas determines their degree of achievement of mathematical knowledge. Unfortunately, some teachers do not pay attention to mathematical formulas The deduction or deduction is not in place, leading students to master the knowledge in the “hunger ” or “eating cooked rice ” state, which is extremely unfavorable to the students thinking and development.Teachers should deal with the generation of mathematical formulas in teaching Heavy enough
