Abstract
Machine learning is used to analyze student feedback in first-year engineering courses. This exploratory work builds on previous research at the University of Toronto, where a multi-year investigation used an online survey to collect quantitative and qualitative data from incoming first-year students. [1] (N ~1000)Sentiment analysis, a machine learning method, is used to investigate the relationship between hours of study outside of scheduled instructional hours and qualitative survey feedback sentiment. The results are visualized with chronological sentiment graphs, which contextualize the results in relation to key events during the school year.Large drops in sentiment were seen to occur during weeks with major assessments and deadlines. An inverse correlation between hours spent outside of class and feedback sentiment was also noticed
