Resumen
Massive open online courses (MOOCs) have exploded in popularity; course reviews are important sources for exploring learners? perceptions about different factors associated with course design and implementation. This study aims to investigate the possibility of automatic classification for the semantic content of MOOC course reviews to understand factors that can predict learners? satisfaction and their perceptions of these factors. To do this, this study employs a quantitative research methodology based on sentiment analysis and deep learning. Learners? review data from Class Central are analyzed to automatically identify the key factors related to course design and implementation and the learners? perceptions of these factors. A total of 186,738 review sentences associated with 13 subject areas are analyzed, and consequently, seven course factors that learners frequently mentioned are found. These factors include: ?Platforms and tools?, ?Course quality?, ?Learning resources?, ?Instructor?, ?Relationship?, ?Process?, and ?Assessment?. Subsequently, each factor is assigned a sentimental value using lexicon-driven methodologies, and the topics that can influence learners? learning experiences the most are decided. In addition, learners? perceptions across different topics and subjects are explored and discussed. The findings of this study contribute to helping MOOC instructors in tailoring course design and implementation to bring more satisfactory learning experiences for learners.
