16年的教学实践使我深刻地体验到, 政治课教学有几个障碍:概念艰深枯燥,许多学生难于理解和记忆;教材滞后多变,脱离学生实际,体系庞大。教师要想教的好,必须对知识的内在逻辑烂熟于心;学生要想学的透,必须对知识的整体结构了然于胸。教师教给学生一个完善的、现成的知识体系固? The 16-year teaching practice has deeply exposed me. There are several obstacles to the teaching of political classes: the concept is arduous and boring, many students find it hard to understand and memorize; teaching materials are lagging behind and changing from the reality of the students and the system is huge. If teachers want to teach well, they must be familiar with the internal logic of knowledge; students must be transparent about the overall structure of knowledge if they want to learn. Teachers teach students a complete, ready-made knowledge system.
