The purpose of this study was to assess the cognitive effects of a prototype health education teaching model on the cardiovascular health knowledge of selected sixth grade students. The level of significance for the study was set at .05. No significant differences between pre-test mean scores, experimental to control group were found. Significant differences between post-test mean scores, experimental to control group were noted. No significant differences between control group pre-test to post-test mean scores were found. Although significant experimental group pre-test to post-test mean scores were found in all four locations, no significant differences were found between the experimental post-test mean scores by geographic location.
