概化理论是现代心理测量三大理论之一,它能针对测量结果推论范围或者使用目的的不同而提供多个不同的测量误差估计指标,确定评分者人数,较好地控制评分误差,因此广泛地用于表现性评定中。难美表现项群中,运动成绩的主观评定引发的种种问题一直未见有科学的评定手段,借助于心理测量学中的概化理论可以确定成绩误差的来源,确定裁判员评分信度以及在一定信度条件下所需的最少裁判人数,因此概化理论在体育测量领域具有较大的应用价值。
Generalization theory is one of the three theories of modern psychology measurement. It can provide different measurement error estimation indexes according to the scope of inference or the purpose of use, and determine the number of the scorers and control the scoring error well. Therefore, generalization Used for performance evaluation. Difficult performance of the group, the subjective assessment of sports performance caused by the problems have not been scientifically assessed, with the help of the general theory of psychometrics can determine the source of the error, determine the referee rating reliability and in Therefore, the theory of generalization has great value in the field of sports measurement.
