Picked this up from Will Richardson’s blog. This article from Nicholas Carr needs to be read and contemplated by all Internet educators.
I know exactly what Nicholas Carr means. More and more I find myself engaged in what I call horizontal learning (skimming multiple resources, multitasking), and have to force myself to engage in vertical learning (prolonged focus on a single topic or resource.) There is indeed a change afoot.
Implications? Identify, make explicit, and teach both approaches. See slides 13- 16 of this presentation for more on horizontal v vertical learning.
Addendum to this post
On a related note I just came across this article today - Society Hard-wired for a fall. More on what computer use may be doing to our brains.
