The purpose of this study is to develop a video-based class for evening high school students to use critical thinking in counterargument training of debates, and to clarify what effect the class has on the students. As a result of the research, the following (1) to (3) became clear. (1) The developed classes promoted the development of “awareness of logical thinking” and “objectivity” in the shared group and the individual group, while “inquiry” was promoted only in the shared group. (2) It was found that the achievement level of the critical thinking process in the counterarguments was increased by the class practice in this study. (3) It was found that the number of participants who thought that the class in which students were asked to consider “counterarguments” using debate videos did not affect their interpersonal relationships and did not deteriorate their interpersonal relationships was greater than the number of participants who did not think so.
