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