| Abstract: | In the article, the teaching of senior I on mechanics is introduced, according to my own long experiecne. I believe that we should carry out aim-teaching, and teach students in accordance with their apititude, lecture slowly and easily, stimulate their interests on physics in order to improve the teaching quality. |
