Open Educational Resources
Open Educational Resources (OER) are teaching, learning and research materials in any medium – digital or otherwise – that reside in the public domain or have been released under an open license that permits no-cost access, use, adaptation and redistribution by others with no or limited restrictions. (Hewlett Foundation).
Zero Textbook Cost
ZTC, also known as Zero Textbook Cost or Zero Course Materials, are courses that make use of OER and other proprietary learning materials. These learning materials may be library resources or resources we just don’t have the rights to share.
Low-Cost
A low-cost course a course that costs students a low amount for course materials. This amount is determined by the institution. For example, several institutions consider a low-cost course when students spend a total of $40 or less per course.
