Preparing lessons is a prerequisite and guarantee for teachers to take good lessons. However, many teachers do not realize that we are preparing materials for classes (including preparation materials, preparing students, preparing for teaching methods, preparation methods, and preparing Experiments, etc.) There are blind spots, teachers’ habitual thinking makes teaching less and less innovative.
