Open-source textbooks increase engagement and satisfaction for students, while reducing the financial burden of college. At WSU, you can have your course designated as either OAT-Z (zero cost) or OAT-L (low cost of $50 or less) under our Open / Alternative Textbook Initiative, which gives your course visibility to students in the schedule as an OAT course. Open-source course materials include: Open-access textbook Library resources Open educational materials Multimedia resources Faculty-authored materials For more information on OAT courses and materials, please visit the Open / Alternative Textbook Initiative, where you can also access the OAT course designation request forms. The deadline to submit OAT designation request forms for spring is Monday, Sept. 30.
