One-on-one and small group conversations with an intelligent virtual science tutor.
Computer Speech & Language(2018)
摘要
•My Science Tutor (MyST) is an intelligent tutoring system that engages students in conversations with a virtual science tutor, leading to learning gains comparable to expert human tutors for elementary school students.•The study compared learning gains of students who engaged in one-on-one tutoring sessions with a virtual science tutor, to students in small groups who discussed answers to the tutor's questions. Learning gains were equivalent in the two treatment conditions, and superior to students who did not receive tutoring.•Students provided positive experiences in both conditions. Students in the small group condition reported that they enjoyed arguing with their peers, and believed they achieved a deeper understanding of the science as a result of the discussions.
