Employs latent partition analysis (a multivariate technique) to reveal pre/postcognitive structure of freshman engineering students (N=70) taking general chemistry. Similarities and dissimilarities among high and low scorers are discussed. Arguments for use of this statistical techniques are presented. (DH)

Examined the feasibility of using two microcomputer simulations to improve preservice elementary teachers performance in the formation and testing of hypotheses. Considers the effects of mode of computer instruction and cooperation on the acquisition of skills. (CW)

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…

The nature of cluster analysis and dendograms, subjects, tasks, and results of this study are described. Categories for problems were based on assumptions about the methods used by novice and expert problem solvers in a physics context. (CW)

Discussed is the use of concept mapping as a tool to enhance meaningful learning for college autotutorial biology students. Student attitudes toward concept mapping is described. The correlation between SAT scores and concept mapping was investigated. (KR)
