Adding Structure to Courses Reduces Achievement Gaps


Justin’s Recommendation

In this paper, Sarah Eddy and Kelly Hogan show that adding structure to introductory biology results in reduced gaps in student performance based on ethnicity and generation status. This is also the paper that properly defines low, moderate, and high structure courses.

In this study, we disaggregate student data by racial/ethnic groups and first-generation status to identify whether a particular intervention—increased course structure—works better for particular populations of students. We found that a “moderate-structure” intervention increased course performance for all student populations, but worked disproportionately well for black students—halving the black–white achievement gap—and first-generation students—closing the achievement gap with continuing-generation students. We also found that students consistently reported completing the assigned readings more frequently, spending more time studying for class, and feeling an increased sense of community in the moderate-structure course. These changes imply that increased course structure improves student achievement at least partially through increasing student use of distributed learning and creating a more interdependent classroom community.
