Dr. Danielle Dupuis of the University of Minnesota's Center for Applied Research and Educational Improvement conducted a study on extant data from Read Naturally Live. The focus of the study was Grade 2. The data showed the Grade 2 students who completed more than 24 stories gained 1.57 Average Weekly Improvement (AWI) Fall to Winter and 1.40 AWI from Fall to Spring. These gains are significant when compared to the typical Grade 2 student’s 1.15 AWI.
