Study aim: this study examined the item difficulty and item discrimination scores for the HRFK PE Metrics cognitive assessment tool for 5th-grade students. Materials and methods: ten elementary physical education teachers volunteered to participate. Based on convenience, participating teachers selected two 5th grade physical education classes. Teachers then gave students (N = 633) a 28-question paper and pencil HRFK exam using PE Metrics Standards 3 and 4. Item difficulty and discrimination analysis and Rasch Modeling were used data to determine underperforming items. Results: analysis suggests that at least three items are problematic. The Rasch Model confirmed this result and identified similar items with high outfit mean square values and low Point Biserial correlation values. Conclusions: teachers are in need of valid and reliable HRFK assessment tools. Without the removal of three items in the PE Metrics HRFK exam for 5th-grade students, complete use of the exam could offer incorrect conclusions.

Study aim: To determine the effectiveness of a newly designed series of fitness segments that can be used to provide healthy behaviour knowledge (HBK) for 5th grade Physical Education classes. Material and methods: 641 pupils from six intervention (n = 401) and five control (n = 240) schools were used. The intervention schools received a five-week intervention of 12-minute fitness segments for each class period. A cognitive test that has been shown to produce valid and reliable scores (28-questions) was used to assess pupils’ HBK at pre – and post – examination. Pedometers were also used to examine physical activity levels differences. Hierarchical Linear Modeling using a two-level multilevel model was used to investigate mean changes in HBK between intervention and control groups. Results: Pupils in the intervention classes had 0.8-unit greater mean improvements in HBK than did control pupils (p < 0.05). Girls also had greater mean changes in HBK than did boys (p < 0.05). There was no statistical difference between intervention and control groups in physical activity levels. Conclusion: This type of fitness segment can be one strategy used by teachers to aid the instruction of HBK without decreasing physical activity participation in classes.
