基于粗糙集的高职教师教学能力评价模型的构建与应用

教学能力是教师的基本能力，直接影响教师的教学行为与教育质量，提升教师教学能力是高等教育从“数量扩张”转向“内涵发展、质量提高”新阶段的迫切要求，然而科学全面的评价教师的教学能力一直以来都是一个难题。基于粗糙集理论，构建了一套高职院校教学能力评价的指标体系，通过属性约简降低计算复杂度，并实现了指标权重的客观赋权，在此基础上，将粗糙集与模糊综合评价方法结合起来，建立教师教学能力综合评价模型。系统地探讨了模型建立的全过程思路及方法．并通过实例验证了该方法的实用性和可行性。

Construction and Applications of Vocational Teachers Teaching Ability Evaluation Model Based on Rough Set

Teaching ability is a basic ability of teachers, and it directly affects the teaching behavior of teachers and education quality. Improving teachers＇ teaching ability is the urgent request of that higher education develops from ＂quantity expansion＂ to the new stage of ＂the connotation of development, quality improvement＂, however, a comprehensive scientific assessment of teaching ability of teachers is always a difficult problem. A set of index systems for vocational colleges teaching ability evaluation is built based on rough set theory, the computational complexity is reduced and the index weight is determined objectively through attribute reduction. Then, on the basis of the combination of rough set and fuzzy comprehensive evaluation method, the comprehensive evaluation model of teachers＇ teaching ability, is established. The whole process of the thought and method of model establishment are systematically discussed, finally, examples are given to verify the practicability and feasibility of the method.
