教学的“熟能生巧”即教师在长期教学实践的基础上，掌握了教育教学的内在规律，并在教育教学实践中充分利用这些规律，使自己的教育教学技巧不断升华，面对复杂多变的教学情境充满了教育机智，显得游刃有余，达到了艺术化的境界。但也有一部分教师总觉得教师每天就是备课上课 The “coincidence of practice” of teaching means that teachers have mastered the internal laws of education and teaching on the basis of long-term teaching practice, and make full use of these laws in education and teaching practice, so that their education and teaching skills continue to sublimate and face complex and ever-changing teaching. The situation is full of educated wisdom, and it seems to be a skillful task that has reached an artistic realm. However, some teachers still feel that teachers are preparing lessons every day.
