学生的发散性思维能力的培养 ,也是一个重要的问题 .因此 ,在数学教学中 ,结合课程内容 ,教师适当地提出一些发散性的问题 ,是很有必要的 .当然 ,这类问题不宜太深 ,应当是大部分学生都可能接受的 .在平面解析几何的教学中 ,我们先后提出了四个问题 ,学生反映尚可 .现在整理成? The development of students’ divergent thinking ability is also an important issue. Therefore, in mathematics teaching, it is necessary for teachers to appropriately raise some divergence issues in combination with the course content. Of course, such issues should not be too deep. It should be accepted by most students. In the teaching of plane analytic geometry, we have put forward four questions that students can reflect. Now they are organized into?
