In 30 years we may have a good model

I heard an interesting piece of information from Kristen L. Huff at the College Board during an AERA session. She said that there was a cognitive map made for density which took five years to construct. I’m thinking that we may eventually be able to develop cognitive models in 30 years of sufficient complexity to model 21st Century Skills. But we simply don’t have the time. ETS may believe it won’t take so long given their new “Cognitively Based Assessments of, for, and as Learning”. It gives me insight into the fact that we can’t wait 10 years to perfect this test – we just don’t have the time. I think we do need to have something ready within two-four years. Imperfect yes but a leap ahead.
