The education sector is transforming from e-learning to m-learning due to its motivation capabilities that drive students toward self-motivated learning. However, this requires online participation through quality knowledge sharing (KS) of the social capital (SC) of resources. Past-reported low student participation calls for confirming whether social capital affects KS in m-learning. Scholars assessed this effect—however, not in the education sector—and revealed scant clarification of whether m-learning regulates SC through KS. Hence, this is the motivated aim reflected through a conceptual framework, that is, tested using multiple-regression analysis after collecting data from 334 Ahlia University undergraduate business students. The results confirm that m-learning moderates students’ SC through KS in e-/m-learning on Moodle. Implications for theory, practice, and society are revealed in this article.
