This particular list of characteristics appears in an excellent book that is all but unknown in the states, Learning to Teach in Higher Education, by noted scholar Paul Ramsden. In the case of what makes teaching effective, he writes, “…a great deal is known about the characteristics of effective university teaching. It is undoubtedly a complicated matter; there is no indication of one ‘best way,’ but our understanding of its essential nature is both broad and deep.” (p. 88–89). He organizes that essential knowledge into these six principles, unique for the way he relates them to students’ experiences.
