Most of the university students who learn Japanese as the second foreign language have the common difficulty that is lack of ability to speak. One of the causes is in the teachings. Grammar-Translation Method and pattern practice cause the students over-reliance on reading by eyes. To solve the difficulty, I based the theory of cognitive psychology and communicate-approach and attempted to match with the present learners’ strong point of being good at accepting the visual stimulation in this educational practice. I tried to devise various tasks using a lot of virtual material in order to promote the conversation activities between the teacher and the students and between the students positively.I did the questionnaire survey at the end of the term. The result shows that a good result went up. It is achievement of 3C.1C is comfortable-meaning I could build a comfortable learning circumstance. 2C is communicative- meaning I could promote the conversation activities in the class.3C is confident-meaning the learners have the confidence to speak Japanese.
