Teaching reflection generally refers to the ability of the behavioral subject to critically examine his own behavior and its situations based on something other than himself. Teacher reflection refers to the process in which teachers use the "ectopic" analysis and correction of their own behavior and the basis for their behavior in their education and teaching practice, and then continuously improve their own education and teaching effectiveness and literacy. If a teacher is just satisfied with gaining experience without thinking deeply about the experience, then even if he has 20 years of teaching experience, it may only be 20 repetitions of one year's work. Be good at learning lessons from reflection on experience, otherwise there will be no improvement and you will always remain at the level of a novice teacher.
