Alamo Colleges District is looking for ways to encourage faculty to adopt no-cost materials either through conferences or training on operational educational resources. OERs are free educational materials in the public domain and copyright-free. The materials range from textbooks to full course modules, syllabi, lectures and classroom activities designed for teaching and learning.
