OP-ED Using diverse styles of teaching

Against the view that good teachers should use diverse styles of teaching, I propose that no teacher can possibly do so and still engage in the act of teaching. I hold to this proposition: it is practically and conceptually impossible for a teacher to use diverse styles of teaching. First I review the arguments promoting the use of diverse styles of teaching, and then I adduce arguments against it. Although the arguments in favour are appealing, the counter-arguments make for the plain impossibility of using diverse styles of teaching.
