平面几何教学是整个初中数学教学的重要组成部分 ,它具有严密的逻辑性。教学中 ,教师要充分利用多媒体和电化手段 ,正确使用直观教具 ,指导学生通过观察、比较、动手、实践、猜想、归纳、总结 ,自己获取新知识。下面就在平面几何教学中 ,如何利用自制教具优化教学过程 ,探索创 Plane geometry teaching is an important part of mathematics teaching throughout junior middle school. It has strict logic. In teaching, teachers should make full use of multimedia and electronic means to correctly use visual aids and guide students to acquire new knowledge through observation, comparison, hands-on, practice, guessing, induction, and summarization. The following is how to use the self-made teaching aids to optimize the teaching process in the plane geometry teaching.
