The causal role of students' self-efficacy beliefs and academic goals in self-motivated academic attainment was studied for 102 ninth and tenth graders (50 males and 52 females) using path analysis procedures. Perceived efficacy to achieve motivates academic attainment both directly and indirectly by influencing personal goal setting. (SLD)

How different frames of reference affect the formation of mathematics and English self-concepts was studied for 14,825 high school sophomores from the High School and Beyond Study. Results are discussed in terms of the internal/external frame of reference model and the big-fish-little-pond effect. (SLD)

Examines a demographic or cohort size explanation of why Newfoundland high school girls outperform boys academically.

Female tenth graders (n=217) were less likely than male tenth graders (n=219) to identify missing or irrelevant information in algebra problems. Female eleventh graders (n=234) were less likely than male eleventh graders (n=287) to solve problems with irrelevant information. Results indicate sex differences in knowledge of problem structure. (SLD)
