虚拟学习社区学习评价指标体系的设计

The Designing of Learning Evaluation Index System in Virtual Learning Community

虚拟学习社区学习评价对于规范和约束学习者社区行为具有重大作用，更是提升社区学习者学习效率的重要保障。虚拟学习社区的学习评价指标体系的研究十分重要。研究在理论剖析与原则构建的基础上，初步设计了虚拟学习社区的学习评价体系，进而采用问卷调查的方法开展研究，通过问卷的发放和收回，经过SPSS处理得到问卷的信度和效度检验，得出了虚拟学习社区的学习评价指标体系。依据该评价指标体系，运用层次分析软件计算权重，用模糊综合评价方法，对在虚拟学习社区中学习的某学习者进行了实践评价运用。即首先要确定被评价对象的因素集；然后分别确定各因子权重及其隶属度向量，得到模糊评价矩阵；最后模糊判断矩阵和因子权重向量进行模糊操作和归一化得出模糊综合评价的结果。

Since learning evaluation in the virtual learning community has a significant role in regulating and restraining the behavior of learners in community and also is an important guarantee to improve the efficiency of community learners， the study on learning evaluation index system in virtual learning community becomes highly meaningful. We conducted the research according to theoretical analysis and principles of construction and preliminarily designed learning evaluation index system in the virtual learning community. We implemented questionnaire method to carry out this research by issuing and collecting surveys. We found out the reliability and validity of questionnaire processed by SPSS and obtained the learning evaluation index system in the virtual learning community. Based on this evaluation index system， we used analytic hierarchy process software to calculate weight and performed the evaluation practice on a learner in the virtual learning community through fuzzy comprehensive evaluation method. That is， first of all， to establish factor set of the object being evaluated; and then determine the weight of each factor and its subordinated vector and obtain the fuzzy evaluation matrix. Lastly， by using fuzzy judgment matrix and factor weight to perform the fuzzy operation and normalization to acquire the result of the fuzzy comprehensive evaluation.
