Tailored Nudges Improve Students’ Scores on Mastery-based Assignments
Becky Matz / University of Michigan
Abstract: Mastery-based assignments typically provide students with multiple opportunities to improve their performance, but getting students to take advantage of these opportunities is difficult. We report on the implementation of a two-part series of nudges designed to improve students’ engagement with and performance on mastery-based assignments in high-enrollment, introductory undergraduate courses. Students received one or two email-based nudges for each assignment, providing both decision information and decision assistance. Delivered via email by a digital coaching system that provides tailored support to students, we evaluated the effectiveness of viewing versus not viewing these personalized nudges across introductory courses in mathematics, computer science, and engineering over five terms at a large, research-intensive university. We find that viewing versus not viewing nudges is significantly related to improved outcomes. Viewing the first of the two-part nudge series is associated with a 3% increase in scores on average. Importantly, we found a significant interaction with prior academic performance such that students with the lowest average academic performance across all courses are predicted to benefit the most—up to 9%—from nudging.
