The Effectiveness of a Comparative Advance Organizer in the Learning and Retention of Metric System Concepts.
Kennedy, Keith
Using student ability, measured by grade point average and cognitive structure, as measured by the number of high school and college courses in science and mathematics, as predictor variables, the investigator attempted to determine the reliability of the use of advance organizers to enhance the retention of meaningful concepts. Students enrolled in a required course, Physical Science for Elementary Teachers, were the participants and were randomly assigned to one of three treatment groups. Group 1 received an investigator-developed comparative advance organizer prior to instruction in the metric system; group 2, an investigator-written historical account of its development; and group 3 received no prior instruction and was used for control purposes only. All participants within each group were subdivided according to ability and cognitive structure. The McFee Metric Test, the instrument used as a pretest, the study of experimental introductory passages, participation in learning activities, posttesting, and delayed posttesting were incorporated into the study. A 2 x 3 analysis of variance was used and when significant F ratios were obtained, the Scheffe Test was used in a post hoc partitioning of the sum-of-squares. Results suggested that the comparative advance organizers have potential that needs to be more fully utilized. (Author/EB)
