Abstract: In the seven years and eleven turns of teaching practice of the course "Introduction to Bilingual Physics", we carried out an exploration on a disquisitive and interactive teaching mode. In this paper, we present our original intention and some new ideas about teaching and introduce some teaching methods and applications of the textbook——《Bilingual Physics with Multimedia》 related to this kind of teaching mode. It gained several positive effects for cultivating freshmen students' initiative study and creative ability. We also suggest some measures for enhancing students' abilities in their fouryear study.

Key words: bilingual physics teaching, disquisitive and interactive teaching mode, initiative study, creative ability
