IamNicklaus: On a serious note , interested to hear what you think of the reply in that link , when you have the time .
As mentioned in the link you shared, I think one of the biggest issue is a lot of our conclusions really seem based on anecdotal evidence. We need more large-N studies of digital natives. As the research develops, I think we'll see two things.
On the one hand, we'll see the mean level of computer literacy to be fairly low. On the other hand, I believe the variance will be quite high. In other words, we're likely to see some type of bi-modal distribution (individuals clustered at either end of the computer literacy spectrum).
At this point, all I know is (every semester), I have students who will say to me, "I'm just not good at computers." And the tasks we're talking about are fairly basic.
