Blended Learning and resources
Most academics create their own lecture notes and presentations and make them available to students through their Virtual Learning Environment (VLE). Podcasts, ie audio recordings, may also be created.
Open Educational Resources (OER)
OERs are "educational materials, technologies and resources offered freely and openly for anyone to use and under some licenses to re-mix, improve and redistribute.” http://openlearn.open.ac.uk/course/view.php?id=3636
