Computer-adaptive test (CAT) for criterion-referenced measurement of motor ability of children improving in PE

在运动能力的标准参照测量中，需要有与儿童个体运动能力发展相对应的标准和规范来评价体育运动对儿童运动能力的绝对提高。运用项目反应理论（IRT）对运动成绩模式数据进行分析，以测量小学体育课程中个体运动技能的提高。采用项目反应理论（IRT）对垫式练习、器械体操跳箱单杠、游泳、足球练习的测试项目特征进行分析，确定了适合计算机应用的测试算法。

In a criterion-referenced measurement of motor ability, criterions and standards corresponding to individual motor development in children were required to evaluate absolutely motor ability improving in PE program. Item response theory (IRT) was applied to motor achievement pattern data measured individual motor skill improvement attained in elementary PE program. Test item characteristics for a computer-adapted test algorism were analyzed using IRT on mat exercise, vaulting box and horizontal bar in apparatus gymnastics, swimming, soccer ball exercise were confirmed.
