I have a history of leaning towards Open Educational Resources (OER) wherever possible. It saves students critical dollars, is immediately accessible, and I have found the quality of the texts to be excellent, particularly for introductory courses. I have used these at the College of William and Mary, where I obtained a grant to redesign the syllabus around OER and to test supplemental materials. Further work was supported by CSI, where I was a PI on a campus-wide $126k grant to provide incentives for faculty to switch to OER textbooks and pass these savings onto students.
Below are teaching materials commonly requested:
