Toru Iiyoshi, who directs the Knowledge Media Lab at the Carnegie Foundation for the Advancement of Teaching's Academy for the Scholarship of Teaching and Learning, has written a provocative essay entitled Opportunity is Knocking: Will Education Open the Door?. Iiyoshi argues that the wide-spread adoption of open educational resources is stymied by three major hurdles. The first is that we don't do a good job of describing how to use educational resources in such a way that someone else can adapt and adopt them. He writes "although the tools and resources are readily available, transferring practical knowledge about how to use them is not easy.... Thus, a crucial task before us is to build intellectual and technical capacity for transforming "tacit knowledge" into "commonly usable knowledge." Second, the academic reward structure has stacked the deck against pedagogical innovation by not rewarding the sharing of information about teaching. He writes "If there are no incentives for faculty to use and enrich open educational goods to transform their teaching and student learning, pedagogical practice will always struggle to advance." Third, the deck is further stacked by virtue of our existing organizational structures and publication schemes. He writes, "...we must look beyond institutional boundaries and connect efforts among many settings and open source entrepreneurs."
