In this paper, we try to use fuzzy theory and the treating method of quantitative analysis to combine optimally teaching scores of Back-glissade Push Shot skill and to give an objective technical appreciation method. From the test of significance of correlation coefficient in reaching standard scores and technical appreciation scores of students in an experimental class, we find that there is a high correlation between them. The result shows that the fuzzy appreciation method accords with the fundamental law of physical culture technical appreciation and has practical application in objectively appraising sport scores.
