Educator Online STEM Resources

Developed by the University of Berkeley with multiple partners through NSF funding, Project WISE used knowledge integrated learning environments research to develop learning modules or units. Teachers can establish a class and provide access to their students. The system records student comments, work, evidence and observations and provides a report back to the teacher. There are around 50 units for teacher access.

Whyville is a site where millions of registered "citizens" come from all over to learn, create, and have fun together. Whyville is their world. Whyville has places to go, things to do, and of course, people to see. Whyville has its own newspaper, its own Senators, its own beach, museum, City Hall and town square, its own suburbia, and even its own economy - citizens earn "clams" by playing educational games. And much, much, much more!
Teaching the engineering section in the Next Generation Science Standards has posed a challenge for many science teachers. Architecture activities can help connect teachers and students to other science concepts.
The Concord Consortium hosts a vast number resources from research in science, mathematics, and engineering education to teacher ready resources for discipline specific instruction. Lessons, aligned to the new science standards, include online simulations and student directions. These resources are offered open source and free of charge.
The Education Development Center (EDC) is developing, field-testing, and disseminating professional development materials for mathematics teachers in grades 6-12. These materials highlight connections between important mathematics, effective teaching practices, and the implementation of innovative instructional materials for students.
This STEM site has tools that can help you teach science, technology, engineering and math (STEM). We are currently focused on supporting the teaching of the Next Generation Science Standards (NGSS).
Next Generation Science Standards - is an updated approach to teaching science that reflects our modern world.
PHet - An interactive simulations site hosted by the University of Colorado, Boulder. Educators can provide access to student-friendly, scientifically, and mathematically appropriate simulations. In these simulations the students (or teacher if a demo) can manipulate variables and run multiple experiments. 
Developed by the Success for All Foundation, PowerTeaching Math is an instructional approach that links Common Core, state standards, and school curricula to research-proven instructional strategies and classroom resources that promote rigor and student engagement.
