BYOL-Increasingly, educators are attempting to integrate technology-based practices and resources into classroom instruction. Hanson and Carlson (2005) found that 100% of teachers could articulate benefits of using digital resources in the classroom, but teachers also noted that finding useful digital resources takes too much time and the resources themselves need significant modifications before they can be utilized.

Educational digital libraries seek to provide teachers and learners with access to high-quality, online educational materials by cataloging only resources that meet standards for instructional value and accuracy (NSDL, 2010). The search tools provided by the National Science Digital Library (NSDL) may support efficient identification of educational materials for the classroom because searches conducted using the NSDL return only instructionally-relevant resources that have met preexisting quality standards.

Thus, we hypothesized that searches conducted within NSDL would be more likely to provide high-quality, reusable curriculum materials compared to a commercial search engine. In a study with preservice teachers, we examined how search tools provided by the National Science Digital Library impacted the success with which participants identified relevant educational resources that they deemed appropriate for classroom use.

Findings demonstrated an advantage of NSDL Science Literacy Maps over keyword search tools. NSDL Science Literacy Maps may be effective because they provide teachers with an organized representation of domain learning goals that can help structure the search for educational materials in a domain. We will discuss these results and their implications for practical strategies to support the search for online, educational materials.
