Evaluation Strategy for NSDL

The overarching question for the NSDL evaluation should be, "How does this online network of learning environments and resources support education?" Implied within that question are crucial ones about the NSDL as a defined technology, such as "How are people using it? How well do the mechanisms of acquisition, classification, access, and retrieval work? What is the quality of the resources?" as well as questions about the construction process, such as "How are the collections and tools changing? How well does the distributed development process work?"
