AEA 2011 conference presentation by Andrei Streke and Tsze Chan. The What Works Clearinghouse (WWC) offers reviews of evidence on broad topics in education, identifies interventions shown by rigorous research to be effective, and develops targeted reviews of interventions. This paper systematically reviews research on the achievement outcomes of computer-assisted interventions that have met WWC evidence standards (with or without reservations). Computer-assisted learning programs have become increasingly popular as an alternative to the traditional teacher/student interaction intervention on improving student performance on various topics. The paper systematically reviews computer-assisted programs featured in reading topic areas. This work updates previous work by the authors, includes new and updated WWC intervention reports released since September 2010, and investigates which program and student characteristics are associated with the most positive outcomes. #metaanalysis #Prek-12EducationalEvaluation #2011Conference
