Imagine me and my friend Jamie Mullaney at Goucher college are scheduled to teach "research methods" and "social psych" next semester. We decide to collaborate and use the same syllabi. Each of us enrolls 22 students in each class. But rather than teaching in parallel, we decide Jamie will teach social psych and I'll teach research methods. We schedule classes so that students are meeting at the same time on different campuses; my students participate via video when Jamie teaches and as do her students when I teach. I'm in the classroom for both courses at my end and Jamie at her end. She assesses the work in social psych and I assess the work in methods, but we provide face-to-face feedback for our own students. We estimate the added workload of the remote class is maybe 25%, and the work of being the remote assistant for the other instructor's course is maybe 25%. Thus, each of us teaches 44 students at our home institution with about 75% of the effort. The students get a better designed course, interact with two instructors and a wider diversity of students. Both Jamie and I enjoy having a colleague who is intimately involved our teaching.
