Using OER you have found and decided to adopt is as easy as embedding a link to the material into your Canvas course site. And you can definitely use it just as a free class text or a regular exercise or assignment. However, consider the interesting opportunities that having an editable course text or other resource offers, you might want to consider open pedagogy.
OER are:
- Free to access
- Free to reuse
- Free to revise
- Free to remix
- Free to redistribute
The question becomes, then, what is the relationship between these additional capabilities and what we know about effective teaching and learning? How can we extend, revise, and remix our pedagogy based on these additional capabilities? There are many, many potential answers to this question.
...we hope to provide some tools and techniques to those who want to build a more empowering, collaborative, and just architecture for learning.
