The Texas teacher is part of a small but growing movement of K-12 educators that is latching on to educational resources that are "open," or free for others to use, change, and republish on Web sites that promote sharing. The open-content movement is fueled partly by digital-creation tools that make it easy to create "mash-ups," or digital medleys of content of various types.

Educators and education-oriented groups advocating open content say it saves schools money by spreading the time and expense of developing curricular resources over many contributors.
