The 2013 study, "Interactive Learning Online at Public Universities: Evidence From a Six-Campus Randomized Trial," examined the impact of interactive learning online (ILO) on the pass rates of 605 students enrolled in introductory statistics courses at six public universities. ILO is a form of online course instruction in which computer-guided instruction substitutes for some, though not all, traditional face-to-face instruction. Students learn course material independently and individual student data are used to provide customized instruction. Pass rates in both the intervention and comparison course sections were similar (80% vs. 76%, respectively). The researchers found no statistically significant difference between these rates. This study was well executed and meets What Works Clearinghouse (WWC) group design standards without reservations. Four appendices are included: (1) Study details; (2) Outcome measure for the academic achievement domain; (3) Study findings for the academic achievement domain; and (4) Supplemental findings for the academic achievement domain. A glossary of terms is also included. [The following study is the focus of this review: Bowen, W. G., Chingos, M. M., Lack, K. A., & Nygren, T. I. (2013).
