Three counties in West Virginia have been selected for a new language and literacy research program that will involve 110 pre-school teachers and more than 1,000 four-year olds. The program, to be conducted in pre-school classrooms in Mercer, Cabell, and Kanawha counties, is funded by the Institute of Education Sciences, the research arm of the Department of Education, and will be carried out by the Massachusetts-based Education Development Center (EDC).
