Past MOOC research has tended to focus on learning outcomes valued in traditional higher education settings, such as achievement and retention. This study recognises that student ratings are an important alternative outcome measure in MOOCs. This paper adopted a semiautomatic text mining approach to collect and analyse 8475 ratings and reviews submitted for 1794 MOOCs. The analysis revealed six important themes that contributed to positive ratings: ‘learning’, ‘understanding’, ‘interesting’, ‘videos’, ‘recommend’, and ‘questions’. The paper then investigated the characteristics of each identified theme based on the proximity of themes, distribution of concepts within themes, and important connections. Based on research findings, the paper presents the following propositions to assist educators and providers to enhance the learning experience in MOOCs: (1) provide realistic learning contexts and instructional conditions in MOOCs to facilitate the acquisition of knowledge that transfers more readily to real-world practices; (2) carefully design the instructional conditions so that some mental challenge and stimulation is required for learners to achieve a full understanding of the content, rather than making MOOCs too simple or effortless to complete; (3) design the course content, materials, and communications to generate interest; (4) allocate sufficient resources to create high-quality video lectures; (5) employ video lectures to elicit positive emotions from MOOC learners and simplify complex, difficult concepts; and (6) incorporate discussion boards in MOOCs and invest in human and digital resources to address learners’ queries.

过去的MOOC研究倾向于将重点放在传统高等教育背景中有价值的学习成果上，例如成就和保留率。这项研究认识到，学生评分是MOOC中重要的替代结局指标。本文采用半自动文本挖掘方法来收集和分析针对1794个MOOC提交的8475个评分和评论。分析揭示了有助于获得正面评价的六个重要主题：“学习”，“理解”，“有趣”，“视频”，“推荐”和“问题”。然后，论文根据主题的接近程度，主题在主题内的分布以及重要的联系，调查了每个已确定主题的特征。根据研究结果，MOOC中的现实学习环境和教学条件，以促进获取更容易转移到现实世界实践中的知识；（2）仔细设计教学条件，使学习者需要一定的智力挑战和刺激才能完全理解其内容，而不是使MOOC过于简单或不费力地完成；（3）设计的课程内容，材料，和通信产生兴趣; （4）分配足够的资源来制作高质量的视频讲座；（5）运用视频讲座激发积极情绪从MOOC学习者那里学习，并简化复杂，困难的概念；（6）在MOOC中合并讨论板，并在人力和数字资源上进行投资，以解决学习者的疑问。
