Cool Teaching/Learning Program
Wired recently had an article about a program/technique called SuperMemo (WikiPedia) which uses a pretty sophisticated algorithm to quiz you on information based on a memory reinforcement technique. Basically, you create (or download) a set of "flash cards" for a topic. The program then presents the questions to you, you answer (to yourself - it doesn't interpret your responses or anything) and then you grade each card on a scale of 0-5, where 0 means that you had no idea of the answer, 1 means you remember the subject, but couldn't remember the answer, 2 means you got it right, but it took way too long to recall, 3 means you answered it with some difficultly, 4 means you're pretty sure you've memorized it for now, and 5 means that it's so ingrained in your mind that you're positive you'll remember it for a long time. It goes through each card in the "deck" until you've graded them all with at least a '2', then you're done for the day. The next day (or so) when you run the program, it picks the cards you've graded the lowest and presents them to you. The ones you've graded higher don't always show up, so you may not see a '3' for a couple of days, a '4' might not show up for a week, and a '5' may be up to a month or more. The intervals and technique are based on several psychological studies that chart how long facts hang around in your short term memory and how many times you have to recall them in order to put them in long term memory (the spacing effect and the forgetting curve). It also plays on the psychological finding that being quizzed or tested is the most effective way to study - blind recall and grading/correction has been shown to be much better than re-reading texts, studying notes, or re-copying notes.
It sounded really cool, but SuperMemo is evidently a bit of a mess. The good versions cost money, the web site is pretty ugly, the program has a lot of features for creating content, but it's cryptic and not very user-friendly, etc. That being said, there are some really great resources there on how to write the most effective kind of study questions and I really need to download one of the trial versions and give it a real try..
Since the earlier versions of SuperMemo were free and the algorithms were documented, there is an Open Source version of the same type of tool called Mnemosyne which is much more basic, but free and easier to play around with. The first thing I did was create a deck to teach myself the resistor color code, which I've never really memorized effectively beyond remembering "Bad Boys Rape Our Young Girls But Violet Gives Willingly" and counting on my fingers or looking at a printed chart. After a week or so, I've just about mastered it except for the really odd (and infrequently used) portions, like extremely high tolerances and fractional multipliers.
I wish I'd known about it earlier in the year when I could have got my kids to give it a try. It is particularly good for foreign language vocabulary and for continual reinforcement of things you learn over a whole year. Because of the interval learning, it's not great for stuffing in a bunch of facts to cram for a final. For example, in a history, foreign language, or science class, if you put in your facts and vocabulary at the beginning of each chapter, you can study them up to the test and then keep them in the deck so that you are constantly practicing them up to the final or mid-term. It would have been great for chemistry (memorizing ions and compounds, periodic tables, etc.). Of course, it's not so great for math since it can't "generate" problems.
I'm trying to think of something to memorize next with it to give it a better workout. Any suggestions?
