There should be a corollary to the admonition [to students], “Bring energy for learning; be interested and engaged,” such as “Faculty will resist talking at you. Instead they will capitalize on your energy for learning by developing personalized learning environments characterized by meaningful interaction.”

Deborah Meier argues in The Power of Their Ideas, “Teaching is mostly listening and learning is mostly telling” (1995, p. xi). Likewise, Decker Walker contends in Fundamentals of Curriculum, “The educative effect is greater when students do something than when something is done to them” (1990, p. 479). University faculty rarely apply these aphorisms because they think of themselves first and foremost as mathematicians, philosophers, and psychologists who also happen to teach. Consequently, scant time is spent thinking about whether conventional teaching methods are working. Even less time is spent crafting alternative ones; as a result, a talking at students status quo prevails.
