The Commonwealth of Virginia announces plans for a free, open-source physics textbook.

The Virginia Physics “Flexbook” project is a collaborative effort of the Secretaries of Education and Technology and the Department of Education that seeks to elevate the quality of physics instruction across the Commonwealth. Participating educators will create and compile supplemental materials relating to 21st century physics in an open-source format that can be used to strengthen existing physics content. The Commonwealth is partnering with CK-12 ( on this initiative as they will provide the free, open-source technology platform to facilitate the publication of the newly developed content as a “Flexbook” – defined simply as an adaptive, web-based set of instructional materials.
