Description: David McArthur, senior researcher at GoH and consultant to the National Science Digital Library (NSDL), discusses the benefits for continued investment in the National Science Foundation's maturing program in the cover story of the February issue of IEEE Computer (Vol. 41, Issue #2). The article outlines the past, present, and possible future for the NSDL. McArthur sees NSDL "growing both as a platform for improving the productivity of educational resource development and transforming education research, and also as a tool for creating and managing scientific knowledge about education and learning." On a large scale, he says, the NSDL could become a key part of a new cyber infrastructure for education and education research.
