Abstract: Case teaching is recommended in Computational Physics class in this paper. The advantages of online teaching make such a transformation of teaching mode realize. The old mode of lecture-problems solving-testing scheme should be replaced by the new mode of question-analyze-solution. The results can be obtained through modeling and researching. It provides an opportunity for students not only to apply the physics knowledge but also get a training in science research. It is meaningful for the ability enhancement of the undergraduates.

Key words: Computational Physics, on-line teaching, case teaching
