This website, Open Education Resource (OER) Commons, is a database of over 50,000 open educational resources and free digital content tools including lesson plans, electronic textbooks, and interactive mini lessons. The database is searchable by subject, grade, and material type. Each entry includes clear terms of use and access to the alignment tool to evaluate against quality standards and align with appropriate learning standards. The site also includes a space to submit resources for possible inclusion, join groups of users with like interests, or use an OER to create and share your own lessons that combine text, audio, and video.
This article by Getting Smart, OER Curation at Scale: An Opportunity to Support Personalized Learning, discusses the importance of open education resources to personalized learning initiatives and the things to consider when trying to scale its usage in a school or district.
