Teacher support and learning engagement of EFL learners: The mediating role of self-efficacy and achievement goal orientation

Given the extremely preeminent role of students' learning engagement (LE) in their academic success, investigating the predictors of LE for EFL learners seems critical. Prior research has demonstrated that the external environmental factors (e.g., teacher support) and the internal motivational factors (e.g., self-efficacy, achievement goal orientation) were related to LE, yet the internal mechanism is still under-explored. Therefore, this study attempted to explore the associations between teacher support and LE and the possible underlying mechanism through which teacher support influences LE with individual motivational variables of self-efficacy and achievement goal orientation the mediators for EFL learners in China. A sample of 466 Chinese college EFL learners participated in the study. Results indicated that (1) both academic support and emotional support significantly predicted LE; (2) academic support predicted LE through the separate mediation of self-efficacy, mastery goals and performance-approach goals; whereas emotional support only predicted LE through mastery goals; (3) academic support, but not emotional support, predicted LE through the chain mediation of self-efficacy and mastery goals, self-efficacy and performance-approach goals. These results elucidated the mechanism of different teacher support on LE and provided some implications for promoting EFL learners' engagement.
