Several empirical studies have shown that formative assessment improves student learning. We build on those studies by reporting the results of a natural experiment at The Ohio State University Moritz College of Law. Students in one of three first-year sections had the opportunity to complete a formative assessment in their spring-semester Constitutional Law course. The assessment consisted of an essay question that the professor had used on a prior exam. Students who submitted an essay answer received prompt, extensive written feedback; they also had the chance to discuss their answer with the professor.
Over the course of three years, about half of the students enrolled in the section took advantage of the formative assessment. Those students achieved significantly higher grades on the final exam even though the assessment score did not factor into their course grade. Notably, students receiving this formative feedback also secured a significantly higher GPA in their other spring-semester classes. Both of these effects persisted after controlling for LSAT score, UGPA, gender, race, and fall-semester grades. These controls helped reduce any effect of selection bias on our findings.
In addition to exploring these relationships between formative assessment and academic achievement, we discuss several race and gender effects that emerged in our analyses. Women, for example, were significantly more likely than men to complete the formative assessment. Women also received significantly higher grades than men in a spring-semester course on Legal Analysis and Writing; men, conversely, received significantly higher grades than women in a Legislation course. A race effect, meanwhile, emerged for students with LSAT scores at or above the school median: Among those students, nonwhite students who completed the formative assessment achieved significantly higher grades in Constitutional Law than white students who submitted the same exercise.
All of these relationships deserve further empirical study. In particular, our results suggest the importance of examining the transfer effects of formative feedback, gender differences in law school learning, and paths for improving the academic experience of minority students.
