Peer reviewedAdedokun, Omolola A.; Childress, Amy L.; Burgess, Wilella D. – American Journal of Evaluation, 2011
A theory-driven approach to evaluation (TDE) emphasizes the development and empirical testing of conceptual models to understand the processes and mechanisms through which programs achieve their intended goals. However, most reported applications of TDE are limited to large-scale experimental/quasi-experimental program evaluation designs. Very few…

Abou-Sayf, Frank K. – Community College Review, 2008
The impact of an experimental, one-semester suspension of mathematics and English prerequisites from 12 courses is investigated. Data on enrollment, student performance, and instructor opinions are analyzed for the total group, and results concerning English versus mathematics prerequisites are compared. Implications for further research on the…
