在本研究中，我們運用模糊統計方法對學生學習成就的評量原理作了嚴格的數學分析。我們利用模糊數學理論探討了評量工作本質的模糊性，並且利用三相模糊統計方法，實驗性地對評估對象作模糊評判。研究結果顯示，基於模糊數學理論的評量方式能夠精確地反映客觀學習成果，並且具有傳統方法無法取代的功能。衡諸目前的評量方式，在傾向於教師主觀思維的經驗判斷情況下，我們的研究結果對於如何作精確評量工作提供了一種新方法。

　　　　　In this study, a rigorously mathematical analysis was applied to the evaluation of learning accomplishment. We used the theory of fuzzy sets to explore the uncertainty of evaluation, and employed the three-phase fuzzy statistical method to analyze the test result. According to our results, the theory of fuzzy sets was able to more realistic handling of imprecision and uncertainty in the evaluation process due to human and behavior through process at work. We concluded that the theory of fuzzy sets would offer a useful approach in the evaluation of learning accomplishment.
