What's Old Is New: Improved Learning from Small-Group Tutorials

Abstract

The ubiquity of Large Language Models poses a challenge to student learning in homework-based college courses, where access to easy homework answers devalues the intended productive struggle. To address this concern, we propose Oxbridge-style weekly tutorials, where students present homework problems without notes in a small group with an instructor or TA. We conducted a randomized experiment in an introductory probability class to evaluate the effectiveness of tutorials, finding a significant positive effect of tutorial enrollment on exam grades. We discuss the implementation, challenges, and opportunities in this style of course design.
