As regular readers of this blog and my books know, I’m a big believer in inductive learning (see More Info On Why Inductive Learning Is So Effective and Is This The Most Important Research Study Of The Year? Maybe).

One effective way to use inductive learning is through the use of data sets. You can see examples of these in my ASCD article, Get Organized Around Assets and in a couple of pieces I’ve written for The New York Times.

A key element of inductive learning is having students put the items or passages into categories — that’s a given.

NPR just published a piece this morning on some research that reinforces the importance of this step. The study itself is a bit convoluted so, instead of describing it here, I’m just going to suggest you go over to their site and read Thinking Like A Scientist Can Help Overcome Allure Of Appearances.
