STEM Teaching Tools - stemteachingtools.org
The STEM Teaching Tools website site has tools that help teachers teach Science, Technology, Engineering and Math (STEM). Each tool on the site is focused on a specific issue and uses the best knowledge and practices from research to incorporate into the classroom. The tools on the site have been chosen based on what is of interest to teachers.
STEM Teaching Tools also has PD modules. They have posted open educational resource (OER) versions of their PD sessions. They include everything that PD providers and facilitators would need for PD sessions, including slides, speaker notes, facilitator guide, and embedded resources. They say they will keep adding more over time, so continue to check back.
All of the tools and professional development modules on the website are free to teachers.
