OER/Low Cost Adoption

OER/Low Cost Adoption Process

Provide an explanation or what motivated you to use this textbook or OER/Low Cost option. I chose OpenStax because the offer their online textbooks completely free of charge. The offer material in many subjects. I browsed the book a bit and determined it was user friendly with short sections, illustrations, and review questions to help with understanding.

How did you find and select the open textbook for this course? I have heard great recommendations of the OpenStax textbooks.

Sharing Best Practices: The sustainability of open education relies on sharing with others. Please give suggestions for faculty who are just getting started with OER or Low Cost options.  List anything you wish that you had known earlier.


Describe any challenges you experienced, and lessons learned. The book is free so it does not compare against economics textbooks from the large publishers. The interactive features that often help with understanding (common with large publishers) are not available for the OpenStax book I use. It is lacking in some topics but I have learned to make up for it by creating my own worksheets and spending more time on those lessons.
