Smart, confident, interested: Contributions of intelligence, self-concept, and interest to elementary school achievement

Cognitive and motivational variables are significant correlates and predictors of scholastic achievement. In upper elementary school grade levels, intelligence seems to be more important compared to motivational variables. Regarding motivational variables, (competence) self-concept revealed higher path coefficients in reported grades than interest. Extending these findings to lower grade levels, the present study with N = 858 students that stemmed from grade levels 2, 3, and 4 (n = 253/321/284) revealed that, when all three predictors were jointly considered, self-concept and interest contributed substantially to the prediction of reported grades in mathematics and German beyond intelligence in all three examined grade levels, with the exception of interest of fourth graders in German. Self-concept was the numerically stronger motivational predictor. Significant grade level-related differences of the predictors were not evidenced. The importance of cognitive and motivational predictors for scholastic success in elementary school is discussed.
