Reports results of a study investigating the ability of college students to solve problems using proportional reasoning. Also discusses implications for consideration of Piagetian cognitive level of students in planning college courses. (CS)

Investigates the effect of increase of the M demand of chemistry problems, having the same logical structure, on performance of students having different functional M capacity, cognitive style, and formal operational reasoning patterns. (Author/YP)

Investigated were the relation between functional M-capacity and student performance in solving chemistry problems of increasing M-demand. Student performance decreased as the M-demand of the problems increased. (Author/YP)

Investigates the effect of intensive instruction in cue attendance upon the ability of preservice elementary science methods students to solve paper-and-pencil reasoning tests that require a form of formal operation thought. (Author/HM)
