给予学生更多的交流、讨论、操作的时间与空间,让学生动手操作,经历学习数学的过程,主动获取知识,是当前数学课堂的新理念。但对于学生动手操作时间的切入与掌控、动手操作的内容和取舍、操作中把握的要点等等,很多教师会忽略掉。如何提高操作的有效性是我们数学教师直面的问题。现从操作方式与材料两个方面,结合自身课堂教学经历,提出几点思考。一、从操作方式上分析1.指向性操作尽量少用。学生动手操作的进程与体验受教师的自身影响比较大。操作中由于存在不确定性,有时教师为了便于
Give students more time to communicate, discuss, operate the time and space for students to operate, experience the process of learning mathematics, take the initiative to acquire knowledge, is the new concept of the current mathematics classroom. But for students to cut into the hands of the time and control, hands-on content and trade-offs, grasp the main points of operation, many teachers will ignore. How to improve the effectiveness of the operation is a problem faced by our math teachers. Now from the operation mode and material two aspects, combined with their own classroom teaching experience, put forward some thoughts. First, from the mode of operation 1. Directional operation to minimize use. Students hands-on process and experience by the teachers themselves more influential. Because of the uncertainty in the operation, sometimes the teacher is for convenience
