教学过程是将教材的知识结构转化为学生的认知结构的过程,而要实现这一知识迁移过程,取决于教师对教材理解的深度和广度。因此,教师对教材的精心研究是优化课堂教学提高教学质量的前提。对于要讲解的教材,只有在课前钻研得比较透彻,准备得较为充分,教师在课堂上才能有的放矢,运用自如,才能开启学生的学习智慧,学生学起来才会觉得津津有味,容易接受。一、确定教学目标,激活学生思维对于任何一节数学课,教学目标的确定都十分重要,因为它指出了教学的主攻方向,是教学活动 The teaching process is the process of transforming the knowledge structure of textbooks into the cognitive structure of students. To achieve this process of knowledge transfer depends on the depth and breadth of teachers’ understanding of textbooks. Therefore, the careful study of teachers’ teaching materials is the premise of optimizing classroom teaching and improving teaching quality. For the teaching materials to be explained, the only way to thoroughly study before the class is more thorough preparation is more adequate, teachers can be targeted in the classroom, the use of ease, in order to open the learning wisdom of students, students learn to relish, easy to accept. First, determine the teaching objectives, activate student thinking For any section of mathematics, teaching objectives are very important to determine, because it points out the main direction of teaching is teaching activities
