Anna Rafferty, assistant professor of Computer Science at Carleton College, will be joining the Department of Educational Psychology as a visiting scholar. She will work with Dr. Keisha Varma in the STEM, thinking, reasoning, and learning lab and Dr. Sashank Varma in the Cognitive Architecture Lab.
Her work at Carleton College combines ideas from computer science, education, and cognitive science. She researches applying and developing machine learning and artificial intelligence techniques to improve educational technologies and better understand human learning.
One of her current projects focuses on developing algorithms to automatically assess learners’ misunderstandings from their actions and using these assessments to provide personalized feedback. She applies the core technologies in this project to several domains, including game-based assessments for experiments about concept learning and interpreting learners’ algebra solving strategies.
Additionally, she explores how reinforcement learning algorithms can be used for experimentation within online courses and materials in a way that meets the goals of both teachers and researchers, and examines how middle school students use and interpret interactive models about science content.
Other general areas of interest include automated scoring and feedback for students, especially about strategies and non-written work; individualizing instruction in educational technologies; and how to draw on the strengths of both human teachers and machine learning to most effectively help students learn.
Welcome to the Department of Educational Psychology, Anna!
