英文摘要：

It is an important matter to improve the teaching skills in the teachers＇ professional development. In the narrow knowledge theory horizon, teaching skill is considered to be the result of application of education and teaching knowledge, and grasping the knowledge is the precondition for the formation of teaching skills. The understanding about this is not only unable to reveal the essential attribute of teaching skills but also block the effective formation of teaching skills objectively. Under the general knowledge theory horizon, teaching skill is a typical individual knowledge and contains a large number of tacit knowledge. It is concerned with situational, individuality and practicality. Attention must be paid to these attributes in improving the teaching skills. Teaching practice and studying in the scene is the best way to improve the teaching skills. Analysis of teaching video is an ideal carrier to enhance the skills of teaching.
