在线课程质量综合评价模型的设计和验证

Design and Verification of Online Course Quality Comprehensive Evaluation Model

摘要: 课程质量是开放大学发展面临的最大挑战之一。为了保证课程质量，远程教育机构有必要对课程的结构和组成成分，以及课程规划、实施及其效果开展综合评价。然而，现有的在线课程质量评价标准维度不一，测量指标差异很大，且很少同时兼顾对课程本身质量和课程规划、实施和结果质量的评价。本研究在文献综述和内容分析的基础上，参考已有在线课程质量评价标准，通过对专家、授课教师和在线学习者的问卷调查法、成熟度模型(CMM)分析方法，构建一个涵盖对在线课程本身质量和课程规划、实施和效果进行持续评价的在线课程质量综合评价模型，并利用德尔菲访谈法和层次分析法，确定测量指标的权重赋值。最后，通过邀请远程教育专家、任课教师和在线学习者利用构建的模型，对随机挑选的课程独立评价的方式，对提出的在线课程质量评价指标体系的信效度进行交叉验证。最后，提出完善在线课程质量测量指标体系的建议和在实践中推广测量指标体系的策略。

Abstract: Course quality is one of the biggest challenges facing the development of open universities. In order to guarantee the quality of courses, it is necessary for distance education institutions to carry out comprehensive evaluation on the structure and composition of courses, as well as the planning, implementation and effect of courses. However, the existing online course quality evaluation standards have different dimensions, and the measurement indicators vary greatly, and rarely take into account the evaluation of the quality of the course itself and the quality of the course planning, implementation and results. On the basis of literature review and content analysis, referring to the existing evaluation standards of online course quality, this study constructs a comprehensive evaluation model of online course quality that covers the continuous evaluation of the quality of online course itself and the course planning, implementation and effect through questionnaire survey and maturity model (CMM) analysis of experts, teachers and online learners, and uses Delphi interview method and analytic hierarchy process to determine the weight assignment of measurement indi-cators. Finally, by inviting distance education experts, teachers and online learners to use the con-structed model, the reliability and validity of the proposed online course quality evaluation index system are cross-verified by means of independent evaluation of randomly selected courses. Finally, the paper puts forward suggestions to improve the online course quality measurement index sys-tem and strategies to promote the measurement index system in practice.
