Are you thinking, here we go again with that one-dimension thing? I am. But I need to. Discussions of differentiated instruction needs and challenges could be a transformational school system change lynchpin. I believe that by failure to sort children, through school choice, by ability by subject, we create differentiated instruction needs that only super-human teachers can address. For example, consider this response to Education Week’s second major recent opinion piece, which responded to the first piece that said that adequate differentiated instruction was impossible, and thus was only rarely even attempted: “Because of my constant criticism of differentiation, the district paraded five of the best teachers to show how it is done. But we need a methodology that works for average and below average teachers, too (1/21/15 letters [p 26]).” Indeed, and the rare super teachers can only succeed, partially, because of the limitations of the system and the fact that even super-human teachers still suffer time scarcity and cannot be in more than one place at a time. If we can get that to sink in, the need for transformational school system change becomes an inescapable conclusion.
