ABSTRACT
To prevent the further spread of COVID-19, many teachings were transferred to the Internet. This study unearths the motivations to participate in YouTube as a supplementary learning resource among college students to fight COVID-19. Using an integration and development of TAM and TTF model with 302 registered YouTube students completed an online survey that helped understanding user behavior. Employing a structural equation model on the sample indicated that behavioral intention was significantly influenced by perceived ease of use, perceived usefulness, user satisfaction, and YouTube self-efficacy. However, task technology fit and content richness were not significantly predictive of behavioral intention. Moreover, perceived ease of use and YouTube self-efficacy also was not significantly predictive perceived usefulness. The implications of integrating and development of TAM and TTF with content richness and YouTube self-efficacy model are discussed.
