基于文本情感分析的高职学生在线课程学习体验研究

Research on Online Course Learning Experience of Higher Vocational Stu‐dents Based on Text Sentiment Analysis

探讨高职学生在线课程学习体验,可以提升高职院校在线课程教学质量和人才培养质量,促进高职教育教学改革。使用爬虫软件搜集微博平台上高职学生在线课程学习的评论,对采集的文本数据进行清洗、分词、词频统计、词云绘制和情感分析,发现高职学生虽然较为认可在线课程学习方式,但其在线课程学习体验不容乐观,线上教学并不能完全取代线下教学;学习任务重、注意力不集中、自律性差、听课效率低、学习软件过多等问题在一定程度上拉低了学生的在线课程学习体验。为提升高职学生在线课程学习体验,应关注学生在线学习毅力水平,提高学生在线学习动机,提升师生交互水平,增强其社会临场感。
