Abstract
Getting feedback from the students in education is the key to improving the learning experience in education, but reading through hundreds of feedback forms can be overwhelming. Sentiment Analysis (SA), which is a NLP (Natural Language Processing) technique, comes in interprets the emotions and opinions behind their feedback. This review explores how various technologies like machine learning and NLP are being used to understand student opinions about teaching quality, course materials, assignments, exams, instructional behavior and overall learning experience. Sentiment analysis helps educators understand student concerns, thereby improving the learning experience and promoting a student-centered learning environment. The challenges in these technologies are discussed with future directions. This review would serve as a guide to researchers in the same domain.
