Virtual Teaching Assistant

Virtual teaching assistants (VTAs) are AI-powered systems designed to augment human instructors, primarily by automating tasks like grading, providing feedback, and answering student questions. Current research focuses on leveraging large language models (LLMs) and federated learning techniques to create VTAs capable of handling diverse student queries, adapting to various learning styles, and ensuring data privacy. These systems show promise in improving educational efficiency, scalability, and accessibility, particularly in online learning environments, by providing personalized support at scale and reducing the burden on human instructors.
