>Look at the image below and see if you can pick out the penny that is correct: It’s quite difficult to do, right? And, surely, you’ve encountered the penny hundreds, if not thousands of times Yes, but I don't study the exact details of the penny. I was immediately able to identify any one of the images as "penny", which is what I would expect with the thousands of passing encounters I've had with it. I'm not sure this example gets the desired point across. It might be more on point to have one group of students study several facts simply by reading them repeatedly, while a second group studies by recalling and using the facts in sentences. Then compare ability to recall the facts.
