The impact of online interaction and information technology accessibility on academic engagement among international undergraduate students in Chinese universities: The mediating effect of learning interest

Academic engagement was recognized as a crucial predictor to measure the effectiveness of online teaching of international students. Therefore, this study established a mediating model to explore the mechanism underlying of interaction and information technology accessibility on academic engagement of international students, as well as the impact of learning interest on these mechanisms with the context of online teaching. Using a stratified random sampling method, 1895 international students from 32 Chinese universities were selected. These international students had completed the academic engagement scale, interaction scale, information technology accessibility scale, and learning interest scale. The study variables were analyzed in sequence for reliability and validity, common method biases test, correlation analysis, structural equation model testing, and bias-corrected percentile Bootstrap testing. The results revealed that online interaction positively affected the academic engagement of international students in Chinese universities ($\beta$= 0.35, p < 0.001), and learning interest played a partial mediating role between online interaction and academic engagement (indirect effect = 0.10, 95 % Boot CI = [0.06, 0.13], p < 0.001). Information technology accessibility did not have a direct impact on academic engagement ($\beta$= 0.06, p > 0.05); but learning interest played a complete mediating role between information technology accessibility and academic engagement (indirect effect = 0.09, 95 % Boot CI = [0.05, 0.11], p < 0.001). The results of Bootstrap showed that the mediating effects within the model were significant. The findings of this study explored the potential mechanism underlying the online academic engagement of international students in Chinese universities, and provided empirical evidence for universities and educators to implement differentiated learning support, assist international students in adapting to online learning styles, and stimulate the endogenous motivation of students' learning.
