1. Clear the direction, unify the thinking and make full preparation for review. In the review, we must first stimulate students' "fighting spirit" and let students prepare actively, then the review work will be half done; Then it is to give students a clear review goal and content, let students know that knowledge must be mastered, give them a review direction, and find ways to really make students feel the necessity and importance of review. For example, students can experience the necessity of review by comparing the pre-review test with the post-review test; Let students feel the joy of solving problems every day, so as to experience the importance of review. 2, reasonable arrangement of progress, step by step, steadily improve. The ancients said, "You can't eat hot tofu if you are impatient" and "You can't eat fat dolls in one bite". I think this is very reasonable and more useful to our teacher. My review ideas are from simple to complex, from individual to whole, and then from special exercises. The most important thing is to sum up the topics that are easy to make mistakes, so as to be targeted. Teachers find out the problems that students are easy to confuse, make mistakes and understand in each piece of knowledge, explain and apply them as demonstration examples in the tiling of each piece of knowledge, and teach students application methods and problem-solving skills, so that students can understand the knowledge structure, understand the application scope and master the application methods, which can solve practical problems in life. This is a combination of theory and practice, and many teachers often form determinant in review. First, let students copy theories, theorems and formulas with notebooks. The second is to give students test questions day by day, completely repeating the old tactics of writing books and asking questions about the sea. This method is not advisable. Theory divorced from practice is empty, and practice without theory is blind. Educator Ye Shengtao once said: "The purpose of teaching is not to teach", "Teachers teach not only knowledge, but also methods". Therefore, our review should focus on cultivating students' basic and general ideas and methods to analyze and solve problems, and explain the whole process of problem solving clearly, instead of spending a lot of energy and time on solving and overcoming some difficult problems, not pursuing some particularly ingenious solutions, not being ignorant and half-informed. The most basic and universal ideas and methods are often the most important and applicable feasible magic weapon.
