Gifted Issues Discussion homepage Forums General Discussion Differentiation Doesn't Work

Starting with the gifted-education community in the late 1960s, differentiation didn't get its mojo going until regular educators jumped onto the bandwagon in the 1980s. By my count, the Association for Supervision and Curriculum Development (now known simply as ASCD) has released more than 600 publications on differentiation, and countless publishers have followed suit with manuals and software that will turn every classroom into a differentiated one.

There's only one problem: Differentiation is a failure, a farce, and the ultimate educational joke played on countless educators and students.

In theory, differentiation sounds great, as it takes several important factors of student learning into account:
• It seeks to determine what students already know and what they still need to learn.
• It allows students to demonstrate what they know through multiple methods.
• It encourages students and teachers to add depth and complexity to the learning/teaching process.

Sounds wonderful, doesn't it? The problem is this: Although fine in theory, differentiation in practice is harder to implement in a heterogeneous classroom than it is to juggle with one arm tied behind your back.

Case in point: In a winter 2011 Education Next article, the Thomas B. Fordham Institute's Michael Petrilli wrote about a University of Virginia study of differentiated instruction: "Teachers were provided with extensive professional development and ongoing coaching. Three years later the researchers wanted to know if the program had an impact on student learning. But they were stumped. 'We couldn't answer the question ... because no one was actually differentiating,' " the researcher, Holly Hertberg-Davis, told Petrilli.
