摘要：This paper discusses the effectiveness of mobile instant messaging (MIM) Line in
supporting a blended learning model and elaborates students’ opinion regarding
the limitations of the MIM. A total of 62 pre-service physics teachers were
enrolled in an introductory physics course. Line-supported blended learning was
implemented in an experiment group whereas learning management system (LMS)-
based blended learning was as the control group. Data were collected through test,
questionnaire, and interview. The test and questionnaire consisted of 20 multiple
choice questions and five open-ended questions, respectively. Meanwhile, the
interview was a semi-structured interview performed through a focus group
interview. The analysis results have given the information that there is no
significant difference in the overall improvement of learning outcomes between the
two groups. However, students in experiment group have significantly higher
improvement of analy¬sis skills than their counterparts in control group.
