1活动背景数学教学离不开解题。作为教研员,笔者深入课堂观课发现,教师在解题教学时普遍存在一些问题,具体表现在以下几个方面:一是凭借经验,普遍缺少解题教学理论的支撑。在解题教学中,教师通常知道怎么解,却不知道为什么要这么解。学生通过教师的解题教学,知其然,而不知其所以然,上课好像听得懂,课后却不能独立解题。二是就题讲题,满足于获得正确的结论,缺少对 1 activity background mathematics teaching inseparable from the problem. As a teacher and researcher, the author in-depth classroom observation found that teachers generally exist in the problem-solving teaching problems, specifically in the following areas: First, by virtue of experience, the general lack of problem-solving teaching theory support. In problem-solving teaching, teachers usually know how to solve, but do not know why it is so. Students through the teacher’s problem-solving teaching, know the natural, but I do not know why, class seems to understand, but can not solve the problem after class. The second is on the topic, content to get the correct conclusion, the lack of right
