This study investigated the students' experience and impact of using Science, Technology, Engineering, and Mathematics (STEM) related subjects for mobile learning or mLearning. In this study, mobile learning student-generated activities (SGA) focused on Malaysian universities as a developing country. The study approach was a qualitative case study based on mobile technology usage through 18 focus group discussions amongst students in Malaysia from 10 universities. The students participated voluntarily, and a purposive sampling approach was used. This study examined the students' perspectives using STEM mobile learning through activities created by students in Malaysian universities. The data were analysed using thematic analysis approach. The findings established factors or themes derived from data on the impact of mobile learning for STEM activities created by students in mobile learning from 10 Malaysian universities. The mobile learning framework of best practices emerged from understanding the impact of the research themes from students' experiences. [For the full proceedings, see ED639391.]
