摘　　要：学生的学习评价是学校培养学生的重要组成部分,如何科学地对学生进行综合评价,是学习评价的关键问题。云理论主要是把传统的模糊集理论和概率论结合在一起,将概念的模糊性与随机性进行综合考虑,解决了定性值与其定量概念之间转换问题。该系统建立在云理论基础上,实现了学习评价的不确定转换问题,并应用云重心评价法解决了传统学生学习评价的不足,形成了学习综合评价体系。The learning evaluation for the students in school is an important part to train the students. The scientific evalua-tion for students is the key of learning evaluation. The cloud theory is the one that transforms the qualitative index into quantita-tive concept,based on the fusion of the traditional fuzzy set theory and probability theory. The uncertain conversion of learning assessment was achieved based on the cloud theory. The cloud barycenter evaluation method was used to overcome the short-comings of traditional assessment for student learning,and form a comprehensive evaluation system of the student learning.
