【摘要】："慕课"是在线教育领域的新事物,处于快速的发展和变化之中。与学术出版物相比,博客讨论可能更贴近最新和最普遍的观点。为使国内学者能快速而全面地了解这些话题,文章运用文本挖掘技术对国外研究者近期关于慕课的博客文章进行了分析,用主题聚类和层次聚类概括出当前讨论的主要话题。研究结果表明,学习者、供应商和那些开发了慕课并进行慕课教学的教授,都是慕课的受益者。文章将聚类结果与学术文献结合起来分析和讨论,认识到博客文章的主要话题与学术文献的观点是能够相互印证和补充的。但研究也发现,制约慕课发展的几个关键性因素如课程质量、完成率和评价手段等在博客中讨论得很少。博客讨论中还有一些令人感兴趣的话题,或许从中可以预见后续的研究方向。
