Based on a retrospective survey of university students, this paper clarifies their perceptions about what was learned in the curriculum of The Period for Integrated Studies in Japanese high schools. Based on the results of the survey, we examined the kind of teaching that is necessary and effective. The results revealed the following: First, according to the learners’ experiences and perceptions, those who had more experience with the “presentation” method were more likely to experience improvement in the various skills that the curriculum aimed to develop. Second, it was observed that graduates from high schools that place more emphasis on preparing students to enter university tend to use the “presentation” method. These two points indicate that the “presentation” learning method plays an important role in the integrated studies curriculum in high schools. This finding emphasizes the importance of the “presentation” learning method and encourages teachers to employ it to attain the goals of the curriculum of The Period for Integrated Studies.
