在高中数学教学中出现教学问题是常见的事,尤其是对于普通一线教师来说更是如此.问题是教师专业成长的契机,理清问题出现的状态与原因,可以让教师更好地内化所习得的理论知识.“向量”是新纳入高中数学教学的知识,在对其的教学理解与教学实施中,常常出现一些教学问题,这些教学问题具有一定的代表性.以之为研究对象,可以打开对教学问题研究的视野.教学问题的解决需要两个工具:一是发现问题的工具;二是解决问题的工具.理论与实践在其中不可或缺. Teaching problems in high school mathematics teaching are common, especially for ordinary front-line teachers.The problem is the opportunity for teachers to professional growth, to clarify the status and causes of the problems, so that teachers can better internalize The theoretical knowledge acquired. “Vector ” is the new knowledge of high school mathematics teaching, in its teaching understanding and teaching implementation, there are often some teaching problems, these teaching problems have a certain representation .To study Object, you can open the field of vision of teaching problems.Teaching problems need to solve two tools: one is to discover the tools of the problem and the second is to solve the problem of the tools in which theory and practice are indispensable.
