To the Editor:
When I wrote my Commentary 鈥淒ifferentiation Doesn鈥檛 Work鈥� (Jan. 7, 2015), I anticipated that it would generate some discussion. Indeed, it has. In reading the comments made directly to Education Week on edweek.org, as well as the dozens of emails I have received from readers in several countries, I can conclude only one thing: Differentiation works 鈥� unless it doesn鈥檛.
Many of those who disagreed with my premise touted their own successes with differentiation, while those who struggled with its implementation (mostly teachers) used terms like 鈥渙verwhelmed鈥� and 鈥渄iscouraged.鈥�
Those opposed to my views called me 鈥渕isinformed鈥� or 鈥渘aive,鈥� while those who liked what I had to say applauded my 鈥渂ravery鈥� and 鈥渃larity鈥� in stating the flaws of differentiation.
A good number of readers assumed that I wanted to return to the days of whole-class instruction (I don鈥檛), and surprisingly few readers expressed concerns for how little gifted students benefit from differentiation in heterogeneous classrooms, which was a major point of my Commentary.
My favorite comment came from a reader who stated that differentiation, as a concept, is 鈥渟ublimely beautiful,鈥� while its implementation has been 鈥渞idiculous.鈥� Amen to that.
I stand by my assertion that differentiation in a heterogeneous classroom setting is a difficult, at times impossible, task to complete for a single teacher.
If students were 鈥渟trategically mixed鈥� (as one reader put it) in classrooms instead of being placed haphazardly, without regard to their readiness to learn, then differentiation would have a chance at succeeding. However, until such time, differentiation will leave more students behind than it propels forward.
Editor鈥檚 note: The Commentary 鈥淒ifferentiation Doesn鈥檛 Work,鈥� by James R. Delisle, provoked an avalanche of reader comments. Because of the extraordinary level of interest in the essay, Education Week is publishing this Commentary by one of differentiated instruction鈥檚 foremost proponents, Carol Ann Tomlinson.
