DIR is pleased to announce that today (August 1, 2017) the National Center for Education Evaluation and Regional Assistance (NCEE) announced the release of three new reports:
- “What is Design-Based Causal-Inference for RCTs and Why Should I Use It?”
- “Multi-Armed RCTs: A Design-Based Framework”
- “Comparing Impact Findings From Design-Based and Model-Based Methods: An Empirical Investigation”
These reports can help education researchers use new design-based methods to analyze data from impact evaluations. The novel design-based approach uses the building blocks of experimental designs to develop impact estimators with minimal assumptions, and has important advantages over “model-based” methods that have typically been used in education research. The reports were authored by DIR’s partner, Mathematica Policy Research, Inc., commissioned by DIR, and funded through our Analytic Technical Assistance and Development (ATA&D) contract with the Institute of Education Sciences (IES) in the U.S. Department of Education. DIR, with Dr. Russell Jackson, DIR’s president and CEO as project director, leads the team providing support to Regional Educational Laboratories and other National Center for Education Evaluation (NCEE) contractors for IES.
