外方在线课程质量评价研究——以学生、教师评价为中心

Study on the Quality Evaluation of Foreign Online Courses:Based on the evaluation of students and teachers

随着互联网教育时代的到来,在线课程的推广普及已成为全球教育改革发展的热点。结合国内外多个在线课程质量评价标准,基于BERT-LDA-TextRank(基于TextRank算法的双向Transformer编码器结合隐含狄利克雷分配的模型)与结构方程模型,分别构建“以学生评价为中心”和“以教师(同行、督导)评价为中心”的外方在线课程质量评价指标体系及模型,实现对外方在线课程的多级评价并以学生-教师多视角分析互相佐证,为教学监督及教务管理部门制定具有可操作性的外方在线课程质量监管与评估文件提供行动指南。

With the advent of the Internet education era,the promotion and popularization of online courses have become the hot spot of global education reform and development.Combined several online course quality evaluation standards at home and abroad,based on the BERT-LDA-TextRank(bidirectional encoder representations from Transformer-latent Dirichlet allocation-TextRank model)and structural equation model,the quality evaluation index system and model of foreign online courses are constructed based on“student evaluation as the center”and“teacher(peer and supervisor)evaluation as the center”respectively.Realizes multi-level evaluation of foreign online courses and supports each other with multi-perspective analysis of students and teachers,enriches the theoretical system of foreign online course quality evaluation,guarantees the quality of foreign online courses in all aspects,and provides an action guide for teaching supervision and academic affairs management departments to formulate operable documents for monitoring and evaluating the quality of foreign online courses.
