In collaboration with researchers from the Center for Economic and Social Research at the University of Southern California, Gibson is currently examining the effectiveness of Knowledge in Action (KIA), a project-based learning approach to teaching Advanced Placement (AP) courses. This randomized controlled trial field experiment in 75 schools across five large U.S. school districts is investigating teachers’ KIA implementation and the impacts of KIA on students’ academic performance as measured by AP exam-taking and scores, critical thinking and problem solving skills as measured by the College and Work Readiness Assessment, and intra- and interpersonal skills and civic engagement as measured by a student survey.
