有效教学要以教材为本,只有深入钻研教材、深刻理解教材、准确领会教材的编写意图,才能深入地挖掘教学资源,创造性地用活、用好教材,才能将自己的理解和感悟准确巧妙地融入到数学课堂教学中去,从而让学生建构知识框架。下面结合教学实践谈一谈具体的做法。一、理解教材,明确编写意图教师在研读教材时要吃透教材,很好地领会教材的内涵,理解教材的编写意图,准确把握教材里的知识点及重点、难点。 Effective teaching should be based on textbooks. Only by deeply studying teaching materials, deeply understanding teaching materials and accurately comprehending the writing intent of teaching materials, can we dig deep into teaching resources, creatively use them and make good use of teaching materials to accurately and ingenuously understand and understand them Into the mathematics classroom teaching to go, so that students build a knowledge framework. The following combination of teaching practice to talk about specific practices. First, to understand the teaching materials, clear written intention Teachers should thoroughly understand the textbook materials, understand the content of textbooks, understand the preparation of textbooks intent, accurate grasp of the teaching materials in the knowledge point and the key and difficult.
