I've never seen it thrashed so thoroughly. I agree w. Schmoker. But I'm wondering what others ( esp. ... but not exclusively.... classroom teachers) think.
I also wonder about the politics of it all. Seems like... among other things.... a good "gotcha" gimmick with which to harass teachers.
Or maybe it's just garden-variety ed. bureaucracy stupidity.

When Pedagogic Fads Trump Priorities
By Mike Schmoker
Several years ago, I had a courteous, if troubling, e-mail exchange with the architect of a hugely popular instructional innovation. She had heard that I had been criticizing this approach. (I had.) In a series of e-mails, I explained my reasons, starting with the fact that there was no research or strong evidence to support its widespread adoption. I asked, with increasing importunity, for any such evidence. Only after multiple requests did I finally receive an answer: There was no solid research or school evidence.
The innovation-Differentiated Instruction-went on to become one of the most widely adopted instructional orthodoxies of our time. It claims that students learn best when (despite some semantically creative denial) grouped by ability, as well as by their personal interests and "learning styles."
I had seen this innovation in action. In every case, it seemed to complicate teachers' work, requiring them to procure and assemble multiple sets of materials. I saw frustrated teachers trying to provide materials that matched each student's or group's presumed ability level, interest, preferred "modality" and learning style. The attempt often devolved into a frantically assembled collection of worksheets, coloring exercises, and specious "kinesthetic" activities. And it dumbed down instruction: In English, "creative" students made things or drew pictures; "analytical" students got to read and write.
In these ways, Differentiated Instruction, or DI, corrupted both curriculum and effective instruction. With so many groups to teach, instructors found it almost impossible to provide sustained, properly executed lessons for every child or group-and in a single class period. It profoundly impeded the teacher's ability to incorporate those protean, decades-old elements of a good lesson which have a titanic impact on learning, even in mixed-ability classrooms (more on this in a moment).
When I shared these reasons with educators, many were glad to hear their suspicions affirmed. They had often been required to integrate DI into all their lessons-against their best instincts-as the program morphed, without any reliable evidence of its effectiveness, into established orthodoxy. Others, however, were angered by any criticism of DI. Their reactions stopped some of my presentations dead in their tracks. These educators, and their districts, had invested enormous amounts of time, treasure, and hope in this pedagogical approach.
