The purpose of the study is to understand the mobile-assisted learning situation of international students in China from the perspective of cultural adjustment and explore the affordances for cultural adjustment of these students in this specific situation. This study investigated eight students learning Chinese as a second language in a university in Beijing and using mainly WeChat, a mobile technology. Qualitative methods were employed in this study. The researchers followed the students for three months (from September to November 2018) and collected all the online messages in the WeChat online group. Moreover, eight one-hour in-depth interviews with participants were conducted. Results showed that the characteristics of the international students' cultural adjustment in the mobile learning environment are universality, consciousness and unconsciousness, and interactivity. In addition, three affordances were identified: resources on Chinese linguistic and cultural knowledge, ways to obtain social support, and ways to relieve stress. Finally, two suggestions for international students are proposed. [For the complete proceedings, see ED600837.]
