In addition to a counterintuitive organizational scheme, integrated commercial systems have a built-in pedagogy, evident in the easiest-to-use, most accessible features. The focus on presentation (written documents to read), complemented by basic "discussion" input from students, is based on traditional lecture, review, and test pedagogy. This orientation is very different from the development of knowledge through a constructivist, learner-centered, or inquiry-based approach, which a number of faculty use successfully in the classroom.
