To help in this process, experience can be gained from projects and initiatives which have acted as forerunners to this movement. Here we present the experiences gained and lessons learnt from one such project based around the open sharing of reusable learning objects in health sciences education. In particular we share our experiences of reuse, its patterns, measurement, drivers, barriers, and tools designed to balance the pedagogical tensions between use and reuse. Like many in the OER movement we promote an emphasis on the role of community-building. We also argue that in order to produce materials that are worth sharing, value must firstly be placed on developing materials suitable for primary use, including robust evaluation and an alignment to real-world learning needs. Lastly, unlike the prevailing trends in OER we urge a consideration of quality assurance and outline the role that it can play in promoting sharing and reuse.yeshttp://dx.doi.org/10.5334/2010-4http://dx.doi.org/10.5334/2010-4168-1747-1-PB.pdf
