This investigation focuses upon the question of: (1) how naive subjects organize and represent knowledge when solving problems; (2) how previous experience of a novice is used in solving a problem; (3) what kinds of information and knowledge are sought as well as overlooked by novices when solving problems; (4) what kinds of strategies novices…

Research indicates that novice problem solvers represent and organize knowledge differently from experts. The novice engaged in problem solving activities is of interest to educators because efficient instruction reduces the differences between initial intuitive knowledge representations and the true concepts to be mastered. A particular cognitive…

This research compared the performance of ninth grade females and males on flight protocol, with particular attention to interpretation of the graphs of paths of falling bodies, rolling objects, and projectiles. These subjects were chosen because they had received no formal instruction in projectile motion, yet through typical life experience, had…
