Five universities in northern Kyushu collaborate to hold a debate class in the training camp style. The debate class has been carried out as a part of “Program for Promoting Inter-University Collaborative Education” supported by MEXT until 2016. After this program, we continue to carry out the debate class every year. It is planned and operated by eight graduate students as secretaries, from selection of debate themes to operation on the day. Thus, students can cultivate the ability of planning, design, collaboration, and communication. However, due to the pandemic of COVID-19, we must switch the debate class from the training camp style to the online style. In this report, we mention the outline of debate class and comparison between these two styles.
