Considerable research has compared how students learn science from computer simulations with how they learn from "traditional" classes. Little research has compared how students learn science from computer simulations with how they learn from direct experience in the real environment on which the simulations are based. This study compared two…

Investigated visuo-spatial ability of a control group and an experimental group (receiving 30 minutes of interaction each week) in undergraduate college biology. Results for the subjects (N=84) indicate that visuo-spatial aptitude can be enhanced through teaching. (Descriptions of interaction sessions and explanations of tasks are included.) (DH)

Explored the effectiveness of the self-initiated modular approach for learning a unit in a human gross anatomy course, and student preference of cadaver dissection versus cadaver prosection. A color scale, the Chromatic Differential Test (CDT), was used to assess general student attitude and preference. (CS)

This was an experiment to test the extended discretion laboratory approach versus a guided-inquiry approach for teaching biology in a university setting. Among three criterion variables (examination, reports, and quizzes), only the laboratory report scores showed differences between groups and group-by-instructor interaction. (Author/YP)

Presented are the results of a study of the effects of peer-led tutoring groups on achievement in college chemistry. Supplemental instruction was effective in increasing students' achievement in chemistry as measured by final grades in chemistry and responses to a questionnaire. (CW)
