In junior high school mathematics teaching, teachers work hard and most students work hard, but the effect is not good, the quality is not high and the ability is poor. What is the reason? Through reflection, I deeply realize that students' enthusiasm for learning mathematics has not been mobilized to the maximum extent, their innovative consciousness has not been aroused, they have not been given the confidence to learn mathematics well, and their good habit of learning mathematics has not been developed, that is, their self-study ability needs to be solved urgently. In this case, I think there are the following points: 1. Seriously solve the two transitions 1. The transition students from primary school to junior high school have a lot of inadaptability and unfamiliarity in learning environment, learning content and learning methods, which requires an adaptation process. Junior one students are only twelve or thirteen years old, which is a transitional stage from childhood to youth. They are highly dependent, not good at independent thinking, and are used to thinking about concrete images. In terms of memory, mechanical memory is much better than understanding memory. They are used to following the teacher's words rather than being good at analyzing and thinking. In view of the above characteristics of junior one students, we should pay attention to step by step in teaching. 2. The transition from teachers to students' self-study is mainly based on listening. Now, it will take a period of time from interest self-study to habit self-study, which is completed in three steps, and we can't rush it. (1) mobilize ideas and clarify the significance of self-study. Let students and teachers communicate, cooperate and explore well.
