This current study is to empirically validate the importance of student's behavioural engagement on online teaching during a coronavirus-2019 disease pandemic. The global spread of coronavirus-2019 disease has affected every aspect of business, including education, resulting in the shift of classroom to online teaching. Keeping in view the growing concern about students' attentiveness, connectivity, participation, and interaction in online classes, the authors underlined the critical need for paying empirical attention to this issue. While addressing a major empirical gap, the present study tested and found the significant role of e-learning efficacy, e-learning resilience, and teachers' instructional innovation in boosting students' online behavioural engagement. Additionally, the study found a thought-provoking direct and interacting role of teachers' instructional innovation. Therefore, the implications of the findings indicate that leaders in educational institutions need to invest in psychological resources that emphasize innovation and creativity in instructional methods for teachers to enhance student engagement in an online environment.
