This Lastinger Center Research Catalyst project, Enhancing Longitudinal Program Evaluations: Estimating Design Parameters and Illustrating Advanced Quasi-Experimental Methods Using UF Lastinger Center Data, supports methods and applied examples for longitudinal education evaluation.
Within the lab, this project provides an applied data setting for longitudinal design planning and quasi-experimental methods. It connects methods development with Lastinger Center program data so that design guidance can reflect realistic education evaluation conditions.
