Saylor Foundation launches open online K-12 courses
Cable Green, July 18th, 2013
The Saylor Foundation recently launched a new K-12 program on Saylor.org, debuting courses for grades 6-12 in English language arts and mathematics. A team of experienced educators and staff are developing courses fully aligned to the US Common Core State Standards. Like Saylor’s college-level courses, the K-12 program incorporates open educational resources (OER), making the courses, as well as their contents, widely reusable by students, teachers, and parents nationwide. The course frameworks and instructions are available under a Creative Commons Attribution (CC BY) license. Thus, while the courses are ready for use as-is, anyone may also reuse, revise, remix, and redistribute their courses to meet local needs.
Following its higher education model, Saylor’s K-12 team focused on reviewing and vetting an existing pool of OER, selecting the best OER to develop instructions and learning outcomes. With Common Core standards providing a framework for each course, Saylor aims to make K-12 OER easy to find and use. Saylor is currently working on 18 additional courses which will be rolled out as they are completed. Read more.
