This documentation describes the policies, procedures, and services that existed while NSDL was operated by UCAR.
The APIs access a database based on the learning goals from the AAAS Benchmarks for Science Literacy and the visualizations from the AAAS Atlas of Science Literacy (AAAS Project 2061), which demonstrate the connectedness of ideas and skills that students should develop over time.
The SMS is produced by researchers from the University of Colorado at Boulder and Digital Learning Sciences, and is based on the strand maps developed by Project 2061 at the American Association for the Advancement of Science and published in the Atlas of Science Literacy, Volumes 1 and 2 (2001 and 2007, AAAS Project 2061 and the National Science Teachers Association).
Strand Maps based on the learning goals from the AAAS Benchmarks for Science Literacy and the visualizations from the AAAS Atlas of Science Literacy (AAAS Project 2061) are made available through the Strand Map Service APIs. Developers can use the APIs to insert interactive Strand Maps in to Web pages, navigate the information space and access objects and visualizations. The diagram below shows an overview of the Strand Map Service technical platform.
