The Office of Educational Research and Improvement (OERI) of the U.S. Department of Education supports educators and policymakers in their efforts to solve pressing education problems through a network of 10 regional educational laboratories. These regional educational laboratories try out new approaches to teaching and learning; provide training and technical assistance to teachers, administrators, and policymakers; and disseminate knowledge and findings about what works with diverse student groups under a variety of conditions. This document describes this program. It begins with a map of the United States depicting the regions served by each of the laboratories and lists the 10 laboratories with their addresses. Information abstracts are given for each, including address, executive director, deputy director, board chair, and region served; a description of the laboratory; a listing of the projects carried out by the laboratory; and the name of the OERI liaison responsible for the laboratory's work. The name of the contact person for each laboratory follows the program description in parentheses. (JLB)
