Some kids appear to learn faster than others. A few years ago, a group of scientists at Carnegie Mellon University decided to study these rapid learners to see what they are doing differently and if their strategies could help the rest of us.
But as the scientists began their study, they stumbled upon a fundamental problem: they could not find faster learners. After analyzing the learning rates of 7,000 children and adults using instructional software or playing educational games, the researchers could find no evidence that some students were progressing faster than others. All needed practice to learn something new, and they learned about the same amount from each practice attempt. On average, it was taking both high and low achievers about seven to eight practice exercises to learn a new concept, a rather tiny increment of learning that the researchers call a “knowledge component.”
“Students are starting in different places and ending in different places,” said Ken Koedinger, a cog..
