Open Educational Resources

What are Open Educational Resources?
OER are resources that have been created by and for teachers, students, and their families.  Something as simple as a YouTube video can be an open educational resource. More formal examples are museum websites and teaching sites such as Khan Academy. This page links to online resources that have been curated by the former and current librarians for their connection to our curriculum and educational goals.
This is only a small sampling of what is available out there on the web! If you need help finding resources for a specific project, class, or interest, contact the librarian.
Who can use them?
All students, family members, and teachers.   Remember, these are available in addition to our research and video databases on the main page.  All students have access to all the databases.
