We need internationally available and effective science inquiry curriculum materials and instructional strategies. Inquiry instruction is especially important to prepare students to deal with the complex science issues we face today such as setting sustainable energy policies, making sensible health-related decisions, and ensuring food safety. We report on a successful, open source learning environment that supports authoring and customization of inquiry science materials. The Technology-Enhanced Learning in Science (TELS) National Science Foundation (NSF) funded center for learning and teaching created an educational accelerator to promote inquiry learning. The educational accelerator includes the Web-based Inquiry Science Environment (WISE), a set of curriculum units implemented in WISE, and a synthesis of research on science inquiry called knowledge integration (Linn & Eylon, 2011).
