Description: In response to the COVID-19 pandemic, many schools in Oklahoma adopted new models of instruction to provide a safe learning environment for students. These models included blended or hybrid models of learning, in which some instruction was delivered in a classroom while other instruction was delivered online. To inform these efforts, the Oklahoma Department of Education asked REL Southwest to provide training and conduct an evidence review on blended learning interventions that are effective at improving student academic achievement.
In conducting the evidence review, REL Southwest reviewed more than 900 studies that had been compiled in the What Works Clearinghouse (WWC) Studies of Distance Learning database. REL Southwest staff then screened the studies to identify those that met the following criteria: were conducted in the last 20 years in the United States; described an intervention that could be used for blended learning; included elementary, middle, or high school students; demonstrated statistically significant and positive findings; and included treatment and control groups.
