Teacher's Emotional Support and Math Performance: The Chain Mediating Effect of Academic Self-Efficacy and Math Behavioral Engagement.

Positive teacher-student interaction can exert a positive influence on student engagement and math performance. As an important part of teacher-student interaction, emotional support of a teacher plays an indispensable role in the math performance of junior middle school and elementary school students. This study aimed to explore the effects of teacher's emotional support on math performance, and examine the mediating role of academic self-efficacy and math behavioral engagement. A total of 1,294 students in grades 3-5 and 7-8 from 14 junior middle and primary schools in China took part in the web-based survey. Results showed the following: (1) academic self-efficacy mediated the relationship between teacher's emotional support and math performance of Chinese primary and middle school boys and girls; math behavioral engagement mediated the relationship between teacher's emotional support and math performance of Chinese primary and middle school boys and girls; (2) The relationship between teacher's emotional support and math performance of Chinese junior middle school boys and girls was mediated by the chain of academic self-efficacy and math behavioral engagement.
