Social networking has opened up new avenues for learning and knowledge sharing. Because of its document exchange, virtual communication, and knowledge production capabilities, social media is a helpful tool for learning and teaching. This research embraces multiple goals. First, this study examines Bangladeshi university students’ social value, communication and collaboration, trust, and the perceived benefits of knowledge sharing through social media in academic advancement. The second goal is to examine how families and technology support mediate those aspects of social media knowledge sharing with student academic development. This study uses the Technology Acceptance Model and Social Exchange Theory as an example of how knowledge sharing through social media with the help of family and technology impacts academic progress among Bangladeshi university students. This paper uses PLS-SEM on the survey data from 737 Bangladeshi students to test the model with the help of SmartPLS 4. Social value, communication and collaboration, trust, and the perceived benefits of sharing knowledge through social media significantly enhance Bangladeshi students’ academic growth. In the case of mediation, family and technological support mediate the relationship between communication and collaboration, trust, perceived benefits and academic development. However, there is no mediation between the social value of knowledge sharing in social media and students’ academic development. The article concludes with implications, limitations, and future research.
