OK, here’s a report!
I love Supermemo. Although we didn’t study so much over the summer, we continued to do Supermemo review daily. During summer we stopped adding questions and tried to get the daily commitment down to something manageable, but then about a month ago I decided to upgrade to the latest Supermemo which enabled us to put questions in priority order and “postpone” any items that are left over. So now we review 40-50 questions per day, no more. Now we’re adding lots of questions every day, 10-15 per day I guess. We now have over 1,000 questions in the database, and according to Supermemo’s statistics, he has 92% retention of this material. It used to be 95%, but went down after we started using the priority+postponing feature. This is to be expected: if you increase the amount of material in the database more than you can effectively memorize, your retention rate will drop. But I say it’s better to have 90% retention of virtually all the material we want to retain than 95% retention of only a very modest amount of material. The most difficult part of the priority+postponing feature has been going back and prioritizing ~800 old items. I still have 400-500 items to prioritize. But it’s really a great system–works excellently. We almost always review the stuff that I think is important, and we do eventually get around to less important stuff.
We’ve added questions from two new sources. Beginning this new school year, H. has been reading (to himself, during his hour-long reading period) Tom Sawyer and Treasure Island, the originals, without much complaint and even with a bit of enthusiasm. But since these are quite advanced, of course he doesn’t know quite a bit of the vocabulary. So I sit him down with my iPad, with the dictionary app open (and a stern warning not to open any other apps), and he looks up words he doesn’t know. Afterwards, sometimes (only 1/3 or 1/2 of the time) I mine his words looked up for items to add to Supermemo. He has memorized a few dozen vocab items that way. Another thing he does now is read to himself nonfiction a half-hour and sometimes a full hour, in addition. This is because I am now using mealtimes to read to baby E., not H. Since I have no time to read and analyze this nonfiction material for him, I have him make questions after he’s done reading. He ends up making far too many questions, half of them being about trivia that he needn’t memorize, but half of them being perfectly fine. This is also an excellent way to get him to think about what he has just read. I type in a selection of his questions and I think he enjoys seeing material that he read to himself.
This has made it possible for him to read and learn a lot from various books about the human body (his latest “what I want to be when I grow up” is a doctor). We got the entire “Horrible Science” series in a box, $50 or so for 3000+ pages (http://www.amazon.com/Bulging-Box-Books-Horrible-Science/dp/1407110357), which looks great and he’s been reading them just for fun quite a bit. It has a lot about the human body, about 5 books relevant. Very much a boy’s series of books. Anyway, sometimes he makes questions about those, but more often his questions are from the “True Books” we got.
In just the last week we switched from one long review, which was cutting into evening reading time, to three short reviews, before breakfast, after lunch, and before bedtime reading, each session 15 questions in 7.5 minutes. Often we do more than 15 which is good. Timing the review sessions keeps H. on track–otherwise he gets distracted. 7.5 minutes turns out to be an excellent review length: long enough to do a substantial amount, short enough to seem, well, short. Occasionally we’ve done 10 minutes three times a day but that seems like a little too much.
H. can do review by himself, although I don’t usually ask him to. I’m fairly confident that when E. is ready to start Supermemo, when he’s 4 or 5 or so I guess (I wouldn’t have wanted to do it with H. before age 5), then H will be 9 or 10, and I think he’ll be able to take over all aspects, question-writing and review. I’ll be sad because I won’t be able to learn everything H. is learning. I’m learning a lot too!
Occasionally H. resists review, but not as much as in the past. Doing it three times a day has made him even more amenable. He is often quite enthusiastic about adding questions and requests that questions be made out of this or that.
One excellent side-benefit of this system is that there is now an easy way to get H. to solidify his memory of all the little pieces of background information: time, measurements, directions, family birth dates, etc. We also use it to solidify his memory of things like skip counting by 3s, 4s, and 6s, and the random addition or multiplication fact that just isn’t sticking.
The bottom line: H. really is learning a lot. If we keep it up, then I am convinced that with significant time investment and support from me, in the first years of doing it, he’s going to know boatloads about everything by the time he is 10. He’ll have memorized zillions of facts he has studied about every period of history, every branch of science, geography, math, grammar, etc.
Reading Bear’s benefactor is very interested in adding a spaced repetition feature to Reading Bear. This will take money and time so I don’t know when you might see it.
H. is no longer reviewing recordings…it just occupies too much time and we couldn’t fit it in along with the Supermemo review.
End of brain dump!
