Self-concept of academic ability as a function of sex, age, and academic achievement among African adolescents.

This study examined (a) sex and age variations for scores on Self-concept of Academic Ability and academic achievement among 244 African adolescents attending a coeducational high school and (b) correlations between scores on Self-concept of Academic Ability and academic achievement by sex and age. No significant sex differences were found, but there were significant age differences on the Self-concept scores and measures of English, science, and history but not in mathematics. A significant positive correlation was found between Self-concept scores and academic achievement for boys and girls and in all age groups, but the magnitude of the correlations with achievement in mathematics was stronger among boys than among girls.
