Also, this past year, Immaculata launched a zero-cost textbook program using Open Educational Resources (OER). The ten OER-based courses replaced traditional printed textbooks with a variety of online resources, including online texts from open-source sites, web-based articles and audio-visual resources in the public domain. The University plans to increase the number of OER-based courses available to students.
