My oldest daughter is gearing up to take the PSAT at the local high school next week, so it's been a time of review. When I registered her, I was handed a test prep booklet and a SAT practice test, which has formed the basis of our review. I say "our", because she and I are going right back to Algebra I.
Looking over the booklets, I find I can answer the literature/reading comprehension/writing questions at the speed of reading. This is not difficult at all for me -- it's the kind of thing I do every day. The math was... the math was harder. I have, literally, a high school math education, as do many liberal arts majors who never had to take a math class in college. As I look at the questions, both in the test booklet and on Khan Academy's prep site, I remember doing these kind of equations as a teenager -- pages and pages of equations, hours and hours worth of work each week. I just don't remember
how they were done. Some things I recall. Balance the sides of equation. Consolidate terms. Cross-multiply and divide for percentages. But there are many concepts and processes that I have to relearn -- linear and quadratic equations, polynomials, trigonometry. These things are not instinctive for me.
On the other hand, there certain kinds of percentage word problems and graph reading that I do find more instinctive. Perhaps these are the kinds of things I have occasion to do nowadays, or the kind of analytic reading that one needs dealing with stats in the newspaper, etc. I can interpret charts in the science articles fairly easily, and when the problems are cast in concrete terms (According to the chart, how does the price of gas change from 1972-1985? If Annie bought 73 pieces of fruit and 23% of them are apples and the rest are oranges, and the next day she bought 104 pieces of fruit but the percentage of oranges stayed the same, so how many oranges were there on the second day?), I find them laborious but not impossible to solve. Some of these problems also can be answered by going with the common-sense solution, and my daughter and I have both found that to serve us pretty well in practice questions.

This isn't the only humbling learning experience I've had lately. The same daughter is taking an online biology course, which requires reading and essay questions and lab work. I have tried to read her biology textbook, and it has taught me something: about myself, not about biology. I'm sad to learn that in terms of biology, I'm the counterpart of those obnoxious people who are so proud of the fact that they think the Odyssey is stupid, and they've lived a perfectly fine life, thank you very much, without ever having read some dead Greek writers.
Cell structures, molecules, mitochondria, endoplasmic reticulum, aquaporins: I read about these things, I look at sentences, sentences made of words which individually I understand, and yet these words put together into a concept of biology slide right off my brain. If I look at them long and enough and read them aloud, I can memorize them for a moment, but when I look away from a sentence, I am unable to tell you what it was explaining. I feel like I have biology dyslexia.
My daughter, fortunately, understands what she is reading, and can explain it convincingly (though not in a way that really takes root in my memory). Her main struggle is with the quintessential homeschool maturation process, in which you learn that yes, in a class you really do need to write out the answers and turn them in, even if you feel like you understand the material perfectly, and that your grade is going to be affected if you don't. And thus I put in far more effort superintending a student studying something that I cannot directly help her learn than I do actually teaching other children material I know well.
This biology illiteracy has served to give me much more sympathy with my 8yo daughter, who has difficulty reading. I have always read almost effortlessly, but for my daughter, who has dyslexic symptoms, the words just seem to slide off her brain. Rules such as "when two vowels go walking, the first one does the talking" have to be retaught almost every time. It helps me to be patient with her when I think of my inability to make any sense of the diagrams in the biology textbook and how anything I picked up has been through dint of sheer memorization. I don't understand my daughter's particular struggle -- I have never in my life had difficulty reading -- but my weaknesses elsewhere inform my ability to help her learn.

The PSAT is next Wednesday. Whether we'll have enough time to get through all our review, I don't know. My daughter also doesn't particularly remember how she did a lot of Algebra II, but it's easier for her than for me,and she's younger and more mentally malleable than I am. The benefit of age and experience is increased perspective and a vast mental library, but boy, is it humbling how hard it is to pick this stuff up again.
