Investigates several aspects of undergraduate students' rules for projectile motion including general patterns; rules for questions about time, distance, solids and liquids; and changes in rules when asked to ignore air resistance. Reports approach differences by sex and high school physics experience, and that novice rules are situation…

Students (n=40) who had experienced cooperative and individualistic concept-mapping experiences performed significantly better in solving three biological problems than did control students (n=20). No significant differences were found between students who mapped concepts cooperatively and those who mapped individually. There were mixed results…

Reviews research on (1) schemata acquisition while learning mathematics and techniques for detecting schema in mathematics learners; and (2) assessment of the distribution of cognitive resources while learning mathematics that lead to the design of instructional techniques to facilitate schema acquisition.

In general, studies investigating sex differences in mathematics performance have empirically analyzed students' responses from standardized tests. This paper reports a study to extend the investigation of sex differences related to mathematics performance by examining cognitive and motivational factors as well as standardized test scores. Boys…
