The study examined perceptions of instructional practices and achievement data from 1,828 students and 141 teachers at 23 sites in 12 states (California, Florida, Iowa, Illinois, Indiana, Massachusetts, Maine, New Hampshire, New York, Ohio, Oklahoma, and Pennsylvania), looking specifically at Edmentum’s online solutions in three instructional settings (pure virtual, blended, and classroom/lab) across four purposes (original credit, credit recovery, intervention, and Advanced Placement). MRL adapted the Marzano Observation Protocol, a comprehensive framework for effective instruction, into student and teacher surveys that measured perceptions of instruction and administered the surveys to the study participants. In addition, student achievement data was collected to analyze the relationship between teacher practices and learner outcomes.
