It’s true that in the pods-and-pinwheel design students can more easily work in smaller groups, but such pods, of course, also offer more opportunity for subterfuge and mutiny.
The blackboard-centered classroom offers more than pedagogical efficiency; it also offers an effective set of teaching possibilities. In such a classroom students are focused on the teacher (on a good day), but most importantly, they are focused. The teacher is not the focus of the class but rather a lens through which the lesson is created and clarified. The teacher draws the class toward her, but she projects the lessons onto the blackboard behind her, a blank surface upon which smaller ideas may be gathered into larger ones. The blackboard is the surface of thought.
The physical dramatics of the classroom – all those bodies and brains ritually focused – can create a new and singular mind, and foster in the individual student an urgent hunger to learn. A good teacher … can, with a nod or a wink, or by simply repeating a key phrase slowly and with certain emphasis, maybe leaning toward her student body, deliver a chapter’s worth of information instantly and unforgettably. Otherwise, we might as well stay home and read to ourselves. The teacher commands her audience, conducts them.
So, basically, the blackboard is desirable because it’s an instrument for teacher control over mutinous students…
