項目反応理論による小学校高学年児童のための走高跳はさみ跳び動作技能の達成度評価基準の構築

In school education, it is important to evaluate the process and results of learning, and to use the results to improve instruction and motivation for learning. However, the standards for movement skill evaluation in physical education have not yet been developed, and currently, evaluation relies mainly on record measurements. The purpose of this study was to develop a criterion-referenced evaluation standard by applying Item Response Theory (IRT) to the scissors jump movement skills taught in upper elementary school physical education classes. First, the structure and measurement items of the scissors jump were clarified, and then, based on IRT analysis, the item and test characteristics of the scissors jump skills were examined. The scissors jump was classified into three phases: running phase, crossing phase, and aerial phase, and consisted of five main movements (straight running, curved running, crossing preparation, crossing, and clearance), ten movements and 26 sub-movements that made up these movements. The high jump scissors jump test items were found to be locally independent, unidimensional, fitted to a two-parameter logistic model (2PLM), and parameter invariant. The constructed criterion-referenced evaluation standard for the high jump scissors jumping movement showed a maximum reliability coefficient of 0.94 at an ability value of -1.2, and a reliability coefficient of 0.8 or higher between an ability value of -2.3 and 1.6. The criterion-related validity coefficients were 0.93 and 0.83, confirming the high validity of the criterion-referenced measurement test. In conclusion, the absolute evaluation standard that can realize objective and reliable evaluation in schools and optimize the learning instruction according to the skill level of each student has been constructed.
