复习是对知识的再认、重组和整合,复习的过程是知识在学生大脑里内化、深化、升华的过程,教师要注重复习课中学生的参与,把握师生互动的节点,在模糊点、疏忽点、易错点、易混点、增长点处引导互动,使复习更有效. Review is the recognition, reorganization, and integration of knowledge. The process of review is the process of internalizing, deepening, and sublimating knowledge in the brain of the student. Teachers must note the participation of students in repetition exercises and grasp the nodes of teacher-student interaction at the fuzzy point. Negligence points, error-prone points, easy-to-mix points, and interactions at the point of growth will make the review more effective.
