The researcher developed robust m...

The Postdoctoral Research Training Program in Education Sciences provided interdisciplinary training in methods for education research, including statistical methods, measurement methods, evaluation methods, and research design to seven fellows

Carnegie Mellon established the Program in Interdisciplinary Education Research (PIER) with funding from a 2004 IES grant. With the 2009 grant, PIER continued to train scientists to conduct rigorous research on learning conditions related to curriculum, instruction, and assessment to improve academic outcomes for diverse prekindergarten through postsecondary students.
