Examining the Reuse of Open Textbooks

An important element of open educational resources (OER) is the permission to use the
materials in new ways, including revising and remixing them. Prior research has shown
that the revision and remix rates for OER are relatively low. In this study we examined the
extent to which the openly licensed Flat World Knowledge textbooks were being revised
and remixed. We found that the levels of revision and remix were similar to those of other
OER collections. We discuss the possible significance and implication of these findings.
