Greek verb forms must be mastered before Plato can be translated. The full light of knowledge is perceived in stages. Learning is hierarchical even if imparted dialectically, for all subjects are better at the beginning than at the end. Teachers resistant to that simple truth about teaching and learning will flounder and will confuse their students. The value of a good lecturer is to know where to begin, what to include and leave out, and by what stages to lead a student to mastery of a subject.
Interactive pedagogy has some uses.
It can serve a purpose or two without pretense to ruling the roost. For example, students can gain experience working with one another by discussing critical questions after the professor has laid a foundation for the discussion. Such an approach probably works best in small groups, such as seminars. But in much of higher education, no interactive model can substitute for a well-organized lecture that structures a mass of information, illuminates basic concepts, suggests applications, reviews relevant literature, and major interpretations, and displays what it means for someone to care about learning, inquiry, and teaching. A responsible lecturer displays lucid exposition,, cogent argument, and enthusiasm about the subject.
