Welcome to the Library Guide on Open Educational Resources

Welcome to the Library Guide on Open Educational Resources of The University of Groningen. In this guide, you can find information on the topic of Open Educational Resources (OER), including what OER are, why and how you can use them in teaching, and how you can make your own teaching materials into OER.

This main page aims to provide a short summary answering the main practical questions about OER: what are they, where can you find them, and what can you do with them. You can also find the latest news about OER-related events at the University of Groningen here. Using the side menu, you can find more in-depth guidelines on different aspects of (working with) OER, inspirational OER examples, and additional resources you can consult for finding (coming soon) or working with OER.

Using OER in Your Courses:

OER are becoming more prominent in higher education. They facilitate a quicker transition to online teaching, help educators reuse and create innovative learner-centered materials, improve access to education, and save resources. This video introduces the topic of OER, explores their practical application in courses, and encourages teachers to use them with the support available at the UG Library.

Would you like to try new and interesting things in your teaching? Do you need some inspiration, practical tools and support with redesigning your courses, making them more open and up-to-date? For the remainder of this academic year (2022-2023), we have two more instances planned where you can get information on and experience with OER.

On May 23rd, the OER team of the library together with didactic experts from ESI will hold an in-person workshop on the topic of OER. You can now sign up for the workshop here via the Library Calendar system LibCal. If you cannot make it to the workshop on this date, you can check out the recording of a previous online version of the general OER workshop (26 October, 2021) and the slides full of useful information on open educational resources.

In March, ESI organizes a Microlab where you have the opportunity to work on your own courses and adapt OER into them. This Microlab consists of an online (to be completed between March 13th and March 26th) and in-person part (March 27th), and you can sign up for it here.
