Abstract
We attempted to create an interaction program with the aims of promoting technical lecture comprehension in students of a preliminary course for Japan-Korea joint exchange program in science and engineering. In this study, students who initially had limited understanding (agreement) of lecture contents participated in interactive activities with peer groups or guests. Through this, a process was observed in which the students gradually proceeded to an enhanced level of understanding (reflection), eventually becoming capable of expressing the concept of the lectures in their own words while displaying an intrinsic understanding of said concepts.
