Method: Two classes from a private, urban high school in a major city within the Mountain West region of the United States participated in the six week study. Group 1 (n=24) completed a unit on personal fitness using the PSI model while Group 2 (n=29) used a traditional, DI approach. Knowledge was assessed three times (pre, post, 3-week follow-up) using a 45-question standardized HRF knowledge test. Class time PA was reported using a modification of the SOFIT observation system.
Analysis/Results: A 2x3 ANOVA was used to compare HRF knowledge scores showing a significant increase in Group 1 scores from pre to post-test (p=0.003) as well as significant increases in scores between Group 1 and Group 2 (p=0.03). Physical activity results were compared using a pair-samples t-test with outcomes revealing differences in class time PA levels (t=-0.27, p=0.79).
Conclusions: These results suggest that PSI is a successful model for increasing HRF knowledge while maintaining physical activity levels.
