"Think you know the best way to study? Better test yourself.
By Daniel Simons, on January 25th, 2011
Imagine you're taking an introductory psychology class and you have to study for your first test. You've read the assigned text, and now you three more days to prepare. What should you do?
1. Re-read the text once more each day
2. Spend each day studying the text to identify critical concepts and the links among them
3. Quiz yourself the first day, reread the text the second day, and quiz yourself again the third day
Do you think you know the answer?
Students in my introductory psychology class regularly come to my office hour after failing the first exam to ask what they did wrong. Some even claim to have spent hours re-reading the text, highlighting important concepts, and even taking notes. Where did they go wrong?
In The Invisible Gorilla, Chris Chabris and I argue that these students fell victim to the Illusion of Knowledge-they thought they had a deeper understanding of the material than they actually did. But why did they have that mistaken intuition? The answer seems to be that they mistook familiarity and fluency for real understanding.
The same principle explains why you might think you know how a toilet works when all you really understand is how to work a toilet-your familiarity with using a toilet leads you to the false impression that you know far more than you actually do. What's most remarkable about the illusion of knowledge is how easily we can overcome it. What's most disturbing is how rarely we actually do.
To determine whether you have genuine knowledge about toilets, just ask yourself a few diagnostic questions and force yourself to answer. For example, how does water fill up the bowl? What causes the water to leave the bowl? Why does water leave the tank? Each time you can produce the correct answer, ask yourself a slightly deeper, next-step question. Eventually, you will reach the limits of your knowledge. You'll
A discussion of "disruptive innovations" and how online learning can be used in brick and mortar schools to engage students in richer, more complex learning experience and increase student/teacher interactions.
