PRISM is a free web site originally designed for Indiana middle school math, science, and technology teachers. It links Indiana Academic Standards for middle school science, technology, pre-engineering, and math (STEM fields) to appropriate, teacher-reviewed online learning activities. Users may either browse materials by academic standard or use the keyword search engine to find appropriate sites. With the integration of the Moodle open source Course Management System, PRISM now serves a much larger audience. Teachers from all grades may use Moodle to establish online classroom courses.
