Samuel Aina’s Three Minute Thesis


Effects of Videocases on Teacher Learning and Classroom Practice: A Meta-Analysis

Studies have shown that videocase analysis, the process of having teachers record, watch and analyze their own teaching, is a powerful approach to developing teacher quality. However little is known about how contextual factors affect the effectiveness of videocases. Do teachers learn better when they watch their own video or a professionally shot video of other teachers? Should they watch their video alone or with other colleagues? How do these and other contextual factors help teachers learn better from videocases? This meta-analysis examined the aggregate effects of videocases on teachers’ learning and practice.

Samuel Aina’s research focus is at the intersection of multimedia learning design, video study, teacher and teaching quality, mathematics education, teacher education reforms, evidence-based practices and meta analyses.

He is currently pursuing a Ph.D. in the Educational Psychology program at Washington State University. His background in teacher education, training development and instructional technology has largely informed his research interests.

He hopes to be a researcher, policy analyst, and professor of educational psychology and teacher education.
