The Kaleidoscope Open Course Initiative aims to improve student success, particularly for low-income and underrepresented students, by creating open educational resource (OER) course designs that can be adopted across institutions. Phase I of the initiative developed 11 OER courses impacting 9,000 students, which improved average student success rates by over 10% while eliminating textbook costs. Student feedback indicated that the OER courses were of equal or better quality than traditional materials and that students preferred the free, digital access provided. Phase II plans to develop additional courses frameworks and grow the number of participating institutions.
