After the outbreak of COVID-19, schools heavily depend on e-learning technologies and tools to shift from in-person class online. This review article analyzes changes technology evolution adoption in pre- post-COVID-19 based Technology System Evaluation Theory (TSET) Unified Acceptance Use (UTAUT). We intend explore interaction different focus two stages particularity heterogeneity UTAUT model. The results indicate that (1) moderating are proposed evaluated under model before COVID-19 outbreak. Studies after pandemic paid more attention efficiency rather than effectiveness; (2) Research focuses infrastructure reach users because is only way continue education; (3) fear moderates relationship between external factors behavior intention users. lack financial support will directly weaken implementation new technology. Social Isolation offers opportunities for students engage e-learning. Meanwhile, it slows down out-to-date hardware software. an enhanced understanding unexpected environments provides practical insights into how promote a accept use easily. study can be tested extended by empirical research future.
