When students apply the knowledge of other disciplines to understand physical education, then the approach is cross-disciplinary.
Absolutely, and I believe it already is! Cross-cultural studies, sociology, and psychology (to name a few disciplines) have already been widely integrated into traditional kinesiology/physical education curriculums at the master's and doctoral levels. For example, how can we design programming sensitive to gender and cultural differences? The participation decline in adolescence, particularly for minority females, is troubling considering the associations between physical activity, healthy development, self-esteem, etc. Considering this decline, I know of exciting research (at least to me!) examining how to increase minority females' participation in physical activity through culturally sensitive programming.
