As the coronavirus disease 2019 (COVID-19) pandemic expanded worldwide, most Japanese universities launched online learning as an emergent measure; hence, securing the quality of online learning remains a challenge. This study aimed to understand reasons behind students’ preferred mode of online learning during the pandemic and to explore the impact of online cooperative learning on students’ class participation by analyzing their voluntary comments. A qualitative content analysis identified three factors that are related to students’ decisions and motivation about participating in synchronous online classes: mutuality resulting from interaction, the impact of COVID-19 on their life and learning, and individual circumstances. This small-scale study was conducted under the unusual circumstance of the pandemic, and the quality of student interaction was excluded from the analysis. However, their enjoyment arising from interaction encouraged their participation in a synchronous class and discussion. They expressed themselves and listened to others attentively, creating a favorable climate for learning. Students’ positive interdependence observed in this study suggests that cooperative learning cultivates a classroom culture where students are willing to contribute without the fear of losing face. This study indicated that participation, cooperation, and active engagement create a positive feedback loop, promoting each aspect even in an online setting.

Exchanges with Chinese students in Japan, who comprise the majority of international students, may be a worthwhile intercultural experience for Japanese students. However, because of the lack of contact between Chinese and Japanese students on campus, many Japanese students tend to form impressions of China through the media. This study aims to explore the factors influencing Japanese students’ positive attitudes toward Chinese students and the former’s awareness of stereotypes based on an online interview in Japanese conducted during an elective political science course. This study adopts a qualitative research methodology to analyze students’ written reflections contextually. The content analysis revealed that Chinese students’ “Japaneseness”, characterized by Japanese language fluency, affected the perceptions of Japanese students, who changed their attitudes toward Chinese people and intercultural exchanges. Further discussion is necessary to determine whether Japanese students’ preferences for “Japanese-like” international students may create new stereotypes rather than enhance diversity benefits. The findings illustrate the need for future research and practice on how students with no experience in communicating with minority citizens can overcome ethnocentric perspectives and embrace diversity.
