This paper explores the associations between math-gender stereotypes and two dimensions of student engagement -- class engagement and disengagement -- among Russian engineering students. The data collected in three Russian universities (n = 2,074) were utilised. Structural equation modelling was employed to test hypotheses about relationships between key variables and their variations for male and female subsamples. We revealed that the students' attribution of math-gender stereotypes to faculty slightly decreased class engagement and increased disengagement for both male and female students. Therefore, we hypothesise that male students can be more overconfident about their future performance in exams on math-related subjects because of a better reputation in the eyes of instructors, which can result in less engagement and, as a consequence, lower academic outcomes. These findings demonstrate the high importance of faculty in encouraging engineering student engagement and providing a bias-free learning environment.
