任何一节好课,教师首先必然要吃透教材,是对教材再认识、再建构的结果,反之亦然。为此,我们教师对教材“三读”、“三把握”:读全册教材,把握整册知识结构;读单元教材,把握单元训练重点;读一课教材,把握本课知识的重点、难点、特点、亮点、疑点等。我们通过读教材,制作知识树,说教材,课堂教学来展示了研读教材的成果。 Any section of a good lesson, teachers must first have thoroughly through textbooks, re-understanding of teaching materials, and then construct the result, and vice versa. To this end, our teachers on the teaching materials “third reading ”, “three grasp ”: read the whole book textbooks, grasping the entire book knowledge structure; reading unit textbooks, grasp the unit training focus; to read a textbook to grasp the knowledge of this lesson The key, difficult, features, highlights, doubts and so on. We have demonstrated the results of our study of teaching materials by reading textbooks, making knowledge trees, teaching textbooks and class teaching.
