农村学校由于教育资源缺乏,学生基础差等原因,使得初中数学成了他们学习中最困难的学科之一。所以怎样对数学进行有效的教学成了教学的重点。教师决不能再用老思维、老方法去授课,在这种背景下,课堂教学不仅仅是书本知识的简单传授,更是要让学生在探索中、实践中学会合作学习、自主学习,最终实现“人人都能获得良好的数学教育,人人都能在数学上得到不同的发展”。 Due to the lack of educational resources and the poor foundation of students in rural schools, junior high school mathematics has become one of the most difficult subjects in their study. So how to carry out effective teaching of mathematics has become the focus of teaching. In this context, classroom teaching is not only a simple teaching of book knowledge, but also to enable students to learn in the exploration, the practice of cooperative learning, self-study, and ultimately to achieve “Everyone can get a good math education, everyone can get different development in mathematics ”.
