Predicting student success in MOOCs: A Comprehensive analysis using machine learning models
Abstract
Background: This study was motivated by the increasing popularity of Massive Open Online Courses (MOOCs) and the challenges they face, such as high dropout and failure rates. The existing knowledge primarily focused on predicting student dropout, but this study aimed to go beyond that by predicting both student dropout and course results. By using machine learning models and analyzing various data sources, the study sought to improve our understanding of factors influencing student success in MOOCs. Objectives: The primary aim of this research was to develop accurate predictions of students' course outcomes in MOOCs, specifically whether they would pass or fail. Unlike previous studies, this study took into account demographic, assessment, and student interaction data to provide comprehensive predictions. Methods: The study utilized demographic, assessment, and student interaction data to develop predictive models. Two machine learning methods, logistic regression, and random forest classification were employed to predict students' course outcomes. The accuracy of the models was evaluated based on 4-class classification (predicting four possible outcomes) and 2-class classification (predicting pass or fail). Results and Conclusions: The study found that simple indicators, such as a student's activity level on a given day, could be as effective as more complex data combinations or personal information in predicting student success. The logistic regression model achieved an accuracy of 72.1% for 4-class classification and 92.4% for 2-class classification, while the random forest classifier achieved an accuracy of 74.6% for 4-class classification and 95.7% for 2-class classification. These findings highlight the potential of machine learning models in predicting and understanding students' course outcomes in MOOCs, offering valuable insights for improving student engagement and success in online learning environments.
