Abstract: Student rating of teaching is the significant component of teaching quality management and plays an important role in the rapid development of universities. A comprehensive evaluation model is proposed based on cloud model. The transform between evaluating factors’ qualitative concepts and their quantitative expressions is executed using backward cloud generator, and the final evaluation cloud model is gained using virtual cloud algorithm. At last, through analyzing the digital characteristics and the cloud drops distribution, evaluation results are obtained. Testified by the experiments, the results are clear and exact, which show that the evaluation method is practical and instructional.

Key words: student rating of teaching, cloud model, backward cloud generator, qualitative evaluation

摘要： 学评教定性评价是高校教学质量管理的重要环节，对高校的快速发展具有积极意义和重要作用。提出基于云模型的学评教综合评价模型，利用逆向云发生器实现评价指标评语的定性定量转换，运用虚拟云的算法获得最终的评价云模型，通过分析数字特征和云滴分布得到评价的结果。实例验证表明，评价结果直观可靠，具有一定的实践意义和指导作用。
