From Affordable Learning Georgia's website:
"Open textbooks are like any other textbook, except that a dedicated team of authors, instructional designers, and/or organizations have made them available for free and have given users the power to adapt them for their students and pedagogy.
Open textbooks are usually licensed under Creative Commons licenses, which give permissions to all open textbook users to revise, remix, redistribute, retain, and reuse them. Although new commercial programs for instant access to textbooks exist, such as inclusive access programs, only open textbooks allow adaptation and remixing, and they do so at no cost to students.."
NOTE: For more information on Open Educational Resource and Open Textbooks, see Affordable Learning Georgia's excellent website on using and implementing OER in the college classroom.
Adopting, modifying, or creating an open textbook for your course is a big decision, requiring you to evaluate new resources often on your own. When you begin evaluating open textbooks, use the following criteria:
Is the content, including any instructions, exercises, or supplemental material, clear and comprehensible to students?
Is the content well-categorized in terms of logic, sequencing, and flow?
Is the content consistent with its language and key terms?
Is the content accurate based on both your expert knowledge and through external sources?
Are there any factual, grammatical, or typographical errors?
Is the interface easy to navigate? Are there broken links or obsolete formats?
Is the resource in a file format which allows for adaptations, modifications, rearrangements, and updates?
Is the resource easily divided into modules, or sections, which can then be used or rearranged out of their original order?
Is the content licensed in a way which allows for adaptations and modifications?
Is the content presented at a reading level appropriate for higher education students?
How is the content useful for instructors or students?
Is the content itself appropriate for higher education?
Is the content accessible to students with disabilities through the compatibility of third-party reading applications?
If you are using Web resources, does each image have alternate text that can be read?
Do videos have accurate closed-captioning?
Are students able to access the materials in a quick, non-restrictive manner?
Does the OER contain any supplementary materials, such as homework resources, study guides, tutorials, or assessments?
Have you reviewed these supplementary resources in the same manner as the original OER?
This repository has all of the Affordable Learning Georgia completed Textbook Transformation Projects. All of these materials are available for free and were authored by USG faculty. It is searchable by course code, course title, or discipline. There are open textbooks available as well as ancillary material. Below is a selection of available textbooks.
These books are peer-reviewed, completely free as an e-book or $50 for a print copy. Some textbooks are optimized to partner with low-cost technology projects such as Carnegie Learning, Cengage, eMath, WebAssign, and more.
Most textbooks also include Instructor Resources such as answer guides, tests, PowerPoint slides, a sample syllabus, and worksheets
