Abstract: In this talk,I shall give a brief report on my teaching of quantum mechanics to junior physics major undergraduate students at Peking University.In order to make it easier for the students to understand the basic ideas and principles of quantum mechanics,I represented the subject by following closely its historical development.More precisely,I explained the achievements of these pioneers,such as N.Bohr,W.Heisenberg,P.Dirac and E.Schrdinger in details.As shown by my own experience, this approach is quite effective.Moreover,I find also that it is very helpful on preaching quantum mechanics to undergraduate students if some parables are properly used in lecture

Key words: teaching quantum mechanics, the historical development of quantum mechanics, using parables in lecture
