> after San Francisco Unified de-tracked math, the proportion of students failing algebra fell from 40 percent to 8 percent and the proportion of students taking advanced classes rose to a third, the highest percentage in district history. Until 10th grade, students take the same mathematics classes. From 11th grade on, students can choose different pathways. That doesn't seem like much time to choose different math…
Specifically, I had a parent that really, really wanted me to do honors math because my older brother did well at it(and he went on to get a math PhD etc.) and math seemed like a ticket to "success" - and so, in both middle school and high school, I was tracked into the middle options, and then within a few days of starting, parent had pushed around the bureaucracy to get me in honors, where I was not completely hopeless all the time, but suffered quite a lot from pressure to succeed and cheated a few times. Finally in my sophomore HS year I managed to fail a class and got switched to the lower track because for some reason you couldn't go from honors down to the middle option...and then some time later, parent tried to make me talk the school into letting me take the AP Calculus course anyway! Which they said "no" to, of course.
Basically, HS math ended with calculus, but even that "lower" track had a strong pre-calc foundation with some trig, linear algebra, etc. At most there was always about a year of difference at stake, in fact - so the post-tracking setup did not change that much. But when I went off to college all these feelings carried over and could not be left behind: I tried taking the engineering Calc courses, hit a wall with integrals, wasted probably a year trying to prove something to myself and developed a miserable self-outlook, settling on an economics degree because it had easier calc courses. (Had I realized that there was also some executive dysfunction in play it might have all been a lot smoother - oh well.)
Basically, parental worry about math tracking created a huge, huge sideline from taking on activities that would have actually helped along my development. It started early and to some extent wouldn't have been stopped by the system, but it would have presented less of a direct obstacle in daily life.
In contrast, the option of self-study and college courses as a supplement has been the path for the truly gifted learners, especially around SF(CCSF, SFSU, USF, and you can go visit Berkeley if that's not enough). That's a way more straightforward way to go about it w/r to a lot of academic topics.
