tailieunhanh - Serving the Needs of Pre-College Science and Mathematics Education: Impact of a Digital National Library on Teacher Education and Practice

One of these websites is maintained by the Eisenhower National Clearinghouse (ENC) for Mathematics and Science The ENC is a centralized site that gathers educational materials and makes them available from its own computers. Content specialists find and acquire the rights to materials, write abstracts for the resources on the site, enter data, and maintain the site catalog—a resource-intensive process that ensures quality while slowing somewhat the provision of resources. A search engine allows users to find the materials in which they are interested. The site is currently getting more than 2 million hits every month, and the clearinghouse expects that number to grow substantially | Serving the Needs of Pre-College Science and Mathematics Education Impact of a Digital National Library on Teacher Education and Practice.
