Guest post by Steve Baule, Educational Leadership Professor at the University of Wisconsin – Superior: As the school year begins, one of the struggles many teachers have is finding good repositories of Open Education Resources (OER). The two biggest challenges to using OER sources seem to be finding them and having the time to curate those appropriate for one’s courses. The OER Commons is a core site with resources from pre-school through adult education. MERLOT is a search engine for finding curated OER resources. It provides some curation tools as well as resources. The Orange Grove is the Florida’s OER Depository. Ck12.org provides a find range of student support resources. Opened.com is a resource site that includes a wide range of assessment materials they cover all areas, but seem to have a wealth of math materials for all levels of students. College Open Textbooks is a great site for those looking to support dual credit or Advanced Placement courses. Additionally, College Open Textbooks includes a link to the OER Handbook for Educators 1.0, which is a good primer for those still learning about how to use OER sources. As the new school year starts, ensure your teachers have the resources to be successful in using OER sources. Happy New (School) Year!
