Open Educational Resources (OER) are educational materials of all kinds (e.g. e-books, videos, worksheets, etc.), which are of increasing relevance, especially in the university context. Educational resources are characterised by the fact that they are freely accessible and are under a free licence. Licenses indicate the use and further distribution of an educational material. For example, they can be (re)used, modified, republished under a different licence.

Retain:
the right to make, own and control copies of the content (e.g. download, store and reproduce)

Reuse:
the right to use the content in different contexts (e.g. in a classroom, in a learning group, on a website, in a video)

Revise:
the right to edit, adapt, change or redesign the content (e.g. to translate a content into another language)

Remix:
the right to combine an original or edited content with other open content and create something new from it (e.g. when incorporating images and music into a video)

Redistribute:
the right to share copies of content with others, in the original or in your own revisions (e.g. give a copy to a colleague or publish it online)

Under oer.uni-due.de the central OER repository of the UDE is being created in a cooperation of ZIM, UB and Learning Lab. If you have materials that are simply too good to keep to yourself, you can upload them to our OER repository as OER and make them available to the public. All you need to login is your unique identifier.

Join in and help to ensure that the number of free educational materials is constantly growing! Or just have a look if you are seeking materials for your course.

If you have any questions regarding the use of the OER repository, please contact oer-repository@uni-due.de.

OER and the corresponding rights can be recognized by an open license. In most cases this is a Creative Commons (CC) license which is internationally accepted and is an alternative to the ubiquitous regulation to reserve all rights, which strongly limits the further use of educational materials.

Materials that are marked with a CC license may generally be reproduced, used and distributed. The description of the respective license indicates the terms of use:
