Supervision is an important part in the implementation of teaching practicum held by initial teacher education. However, such constraints as time, place, and content of supervision become major problems in the implementation of supervision. Thus, this study aims to investigate the use of social media in the implementation of supervision during the teaching practicum program. Specifically, this research aims to a) identify the roles of university supervisors through a social media platform; b) find out the student teachers' and cooperating teachers' responses to the use of social media during supervision. This research involved 8 student teachers, 3 school teachers, and 2 university lecturers who took part in the teaching practicum program in partner schools in Bandung, West Java. The data were collected through conversation transcripts in social media and questionnaires. Using Henry and Weber's framework of supervision (2010) the results showed that almost all the role of supervisors, such as instructor, seminar director, counsellor, liaison, and supervisor, can be done through social media in the form of conversation groups in a social media platform. Student teachers and school teachers expressed a relatively positive impression of them related to the use of social media in the process of supervision. The student teachers and the school teachers also revealed the advantages and disadvantages of using social media conversation groups during the teaching practicum supervision process. It is expected that the results of this study contribute much to the effectiveness of supervision process without the constraints of space and time.
