The Metiri Group's report disputes the widely debated Cone of Experience theory, which says each of us learns 10 percent of what we read, 20 percent of what we hear, 30 percent of what we see, 50 percent of what we hear and see, 70 percent of what we say or write, and 90 percent of what we say as we do a thing. (The rampant misrepresentation of researcher Edgar Dale's valid model of classifying learning styles is discussed in this entry in the blog of educational consultant Will Thalheimer.) After an extensive search, the report's authors were unable to find any empirical evidence supporting this breakdown. Contrary to popular opinion, research shows that lessons in which students interact with material, rather than passively absorb it, are not always better.
Jeff Johnson on 08 Jul 08I've been getting this question a lot lately from administrators, parents, and taxpayers. The question isn't malicious, but rather comes from folks with a vested interest in making sure that our technology dollars directly benefit students. Does giving teachers laptops directly benefit students? For people who aren't actively teaching in a classroom, that's a hard question to answer. I don't think it's very hard for teachers to answer the question, though, especially at the secondary level. For most people entering the business world, there is no question that they will have a computer on their desk when they are hired. It might be a laptop, a desktop, a shared desktop facilitated with some sort of flextime arrangement, or even a computer allowance so that the new hire can buy a machine that makes them the most productive. However, it's not terribly likely that they'll just be handed a dry erase marker and a whiteboard, pointed towards a copy machine, and told to go for it.
