Eisenhower National Clearinghouse for Mathematics and Science Education (ENC) - The ENC is funded through a contract with the U. S. Department of Education to provide K-12 teachers with a central source of information on mathematics and science curriculum materials. ENC was established in 1992 at The Ohio State University and is located in Columbus, Ohio.
LETSNet - LETSNet is a dynamic on-line environment where teachers can develop their understandings of the Web and find ways to effectively use - or make sense of - the World-Wide Web in their classrooms. To help teachers achieve these goals, we have organized teaching resources around classroom teachers' stories, including lesson plans, curriculum standards and guides, pointers to e-mail discussion lists, and many other Internet and Web materials. The stories we have collected about teachers document their feelings about their successes, lessons learned, and plans for future Internet activities with their students.
