近年来,在“生本课堂”的大背景下,围绕课堂教学展开的“导学”设计,使得我们小学数学的教学发生了根本性的变化。在这样的大环境中,小学数学的课前导学应该如何去组织,怎样组织才更有效,教师应该做好怎样的服务,如何有效地引领学生进行学习等一系列问题都摆在了我们的面前。组合自己的课堂教学实际,我发现学生在学习前对新知都有一定的基础,因学习成绩差异,学生对知识的把握程度不一,这就要求教师要有针对性地设计课前导学,体现导 In recent years, under the background of “student-centered classroom”, the design of “teaching” around classroom teaching has fundamentally changed the teaching of our primary school mathematics. In such a large environment, primary school mathematics how to organize pre-class guidance, how to organize more effectively, what kind of service teachers should do, how to effectively lead students to learn a series of problems are placed in our before. Combination of their classroom teaching practice, I found that students before learning have some basis for the new knowledge, due to differences in academic performance, the students grasp the different levels of knowledge, which requires teachers to be targeted to design pre-course guidance, Reflect the guide
