Academic self-concept: A cross-sectional study of grade and gender differences in a Singapore secondary school

Many studies support the existence of a significant decline in students' academic self-concept from early to midadolescence. In comparison, the findings on gender effect are less conclusive. This study aimed to determine whether there is any grade or gender effect on adolescents' academic self-concept in the Singapore context. Specifically, the cross-sectional study was conducted with Secondary 1, 2 and 3 students (N = 656) in a government co-educational school. The results established a significant main effect according to grade, with Secondary 3 students having significantly lower academic self-concept (scale and subscales) than Secondary 1 and 2 students. In addition, there was a significant main effect for gender, with female students having significantly higher perceived academic effort (academic self-concept subscale) than their male counterparts.
