In a recent study at Georgia State University, students who received timely messages about their coursework from a virtual teaching assistant demonstrated significant improvement in their academic success. Researchers conducted a randomized controlled trial using artificial intelligence chatbot technology from Mainstay (formerly AdmitHub) in an Introduction to Government course to provide students with reminders about course requirements and deadlines; customized feedback on their progress; weekly digests with upcoming due dates and estimated time to complete tasks; practice quizzes; coaching and encouragement; and information on campus support systems, tools and resources.
