The network of 10 Regional Educational Laboratories, in partnership with state and local educators, helps schools use research and proven practice to make a difference for children. This report highlights major 1998 accomplishments of the laboratory program supported by contracts with the U.S. Department of Education. In 1998, the Regional Laboratories expanded core support to schools, and new initiatives were mounted. In particular, the Comprehensive School Reform Demonstration Program galvanized activity across the United States, with the Regional Laboratories providing critical assistance. In addition, in 1998 the number of development sites supported by the Regional Laboratories increased from 494 to 615, and the number of application sites increased from 236 to 328. In the same year, the Laboratories more than doubled the number of clients receiving products, and they participated in 171 different partnerships. Laboratories also delivered more than 100 technical assistance workshops attended by 6,000 people. Stories from the individual laboratories illustrate the nature of development and partnership efforts and the products and benefits they offer students, educators, and parents. A capsule description of each Laboratory is provided. (SLD)
