Oregon State University defines a hybrid course as one that "includes both regularly scheduled on-site classroom meetings and significant online out-of-classroom components that replace regularly scheduled class meeting time."

In practice, face-to­ face meeting time in on-campus hybrid courses is generally reduced by 30 to 70% compared to traditional on-campus lecture courses. The most typical scheduling approach for these courses is one class meeting per week, though this varies especially when a course has a lab or recitation.

The broader term "blended learning" may be applied to various teaching modalities that integrate scheduled synchronous class sessions with substantial asynchronous learning activities.

The number of OSU courses that officially carry the hybrid schedule type grew 33% during the past two years. More than 900 courses now carry this designation and approximately 150 hybrid courses are offered each term. Hybrid courses range across the curriculum from 350-student Bacc Core courses to graduate seminars.

In the Schedule of Classes, the schedule type of hybrid courses is Hybrid (HYB). The face-to-face meeting hours of the course are listed in the schedule. The class notes briefly describe the hybrid nature of the course, for instance by saying, “In addition to classroom meetings, this hybrid section includes significant online components that reduce classroom meeting time.”

Hybrid courses offered during regular daytime class hours on weekdays on the Corvallis and OSU-Cascades campuses are considered on-campus courses, rather than Ecampus courses. Tuition for these hybrid courses is the same as for other on-campus courses. Ecampus offers hybrid degree programs and certificates at other sites such as the OSU Portland Center.

All OSU faculty members are eligible to teach hybrid courses with the approval of their academic units.

A call for proposals is issued multiple times each year for participation in a 10-week Blended Learning Faculty Learning Community. Instructors selected for participation receive professional development funding and consultative support to take part in a learning community offered in a hybrid format and to redesign a traditional on-campus course offered in Corvallis as a blended course.
