Memory Revisited All educational reform documents call for powerful learning in a rich common core curriculum for all students. Certainly, in this age of the information explosion, we must teach our students how to access information and how to evaluate the credibility of what they find. However, they must have an accurate knowledge base or their "powerful learning" will be flawed. Rather than seeing thinking skills as "low" and "high" order skills, I think of them as "foundational" skills. I prefer the analogy of the skills in a continuum, perpetuating one another. In fact, we will be ineffective in teaching our students to synthesize, evaluate, and transfer if they don't have an accurate memory bank from which to draw. Recent brain research has revolutionized the way we teach and the results we are able to attain. The Caine Learning Institute devotes principle nine to the concept of memory. They discuss the fact that we have at least two types of memory—spatial and rote. The spatial memory system allows for instant memory of experiences. In the taxon memory system, things are learned by rote. With taxon memory, "the brain is easily fatigued since there is stress on a limited number of brain cells." (Caine and Caine) Skills for the Rote Memory System Teach students to memorize using their rote memory system with a few of SCORE's learning theories:
- To memorize material, rotate what you are memorizing in sets of three. Material tends to become rote after the third repetition; you can say the same thing a dozen times in a row and not increase learning significantly more than when you have said it three times. This is because the brain "shifts into neutral" at that point, and we cease to think as we repeat.
- Maximum time for memory practice is 5 to 15 minutes. If you concentrate for longer than 15 minutes, your brain tires, and you are less productive. When memorizing, concentrate—give it all you've got—for no less than five minutes. Then take a break or change tasks.
- Material being memorized needs a lag time of 2 to 24 hours. After you've worked for 5 to 15 minutes in sets of three, set your material aside for at least 2 hours. Otherwise you haven't forgotten enough and that portion of your brain hasn't rested long enough for maximum effectiveness. Don't leave it for longer than 24 hours, however, or you will have forgotten too much. You will have to re-acquire information rather than review.
- The more you involve yourself in the learning process, the more you will retain. Research (Glasser) implies that a person retains approximately 10 percent of what he/she reads or hears. A mushroom effect occurs, however, when a second sense is added. If you hear and see, or see and say, you could retain as much as 50 percent, with concentrated effort. So when memorizing, involve several senses.
By orchestrating these theories, your students can memorize quickly and easily. Sometimes an assignment to memorize 15 symbols seems impossible. Most students, however, will readily agree to 15 minutes. And most students can memorize 15 symbols, using proper techniques, in 15 minutes. Cramming is never a good strategy (even though it is widely practiced). However, when cramming is necessary, take advantage of these learning theories. Study intensively for 15 minutes and then do something else for two hours. Repeat this process all night if necessary. Add sleep, where your mind replays what you last put into it, and you will, again, retain more. This is a far more effective method than staying up all night, as many of us did in our pursuit of a degree…unless, of course, you, like I, ignore alarm clocks.
