Several methods were offered to improve student engagement, but the one that surprised me was team-teaching. That not only included the obvious gen-ed value of finding cross disciplinary connections to content, but emphasized the value of having more than one faculty member present.
What surprised me was the value that having a faculty member out in the audience with the students gave the students was the feeling of connection and interaction with the instructors they didn't get with a single sage on the stage.
In on-line education we constantly harp on the need for "instructor presence" so the student doesn't feel like they're taking the course from a disembodied program. It's interesting to see that this is a issue in face to face courses too.
