LAWRENCE, Kan. (AP) — The Lawrence school district is preparing to roll out its first class that uses only open-source learning material written by experts, vetted by their peers and posted for free downloading.

To get ready, several administrators and teachers participated in a conference last week in California. The Lawrence Journal-World reports that the conference was part of a U.S. Department of Education campaign, #GoOpen, to encourage states, school districts and educators to use openly licensed educational materials.

In October, it was announced that the Lawrence school district was one of 10 districts nationwide to take up the #GoOpen challenge to replace at least one textbook with openly licensed educational resources within the year.

District administrators have selected seventh-grade English language arts as the subject area for the #GoOpen initiative.
