Not everybody is behind this shiny friendlliness... https://www.familiesforsanfran... from that article: "Goal 1: Reduce the number of students forced to retake Algebra 1, Geometry, or Algebra 2 by 50% from numbers recorded for 6/2013 Claims: In a September 2017 press release SFUSD claims a "dramatic increase in student comprehension" and a drop in Algebra 1 repeaters from 40% to 7%. The press release states that this was found through a “longitudinal data” review of the last class of high school graduates who completed Algebra 1 in 8th grade (Class of 2018) and the first class of high school graduates who were prohibited from that option (Class of 2019). A 2019 case study also attributes the reduction of repeat rate to detracking. Rating: Misleading Facts: The grade distribution we received from SFUSD showed no improvement at all in Algebra 1 grades. The repeat rate did come down, but only because in 2015 SFUSD eliminated the requirement to pass the Algebra 1 California Standards Test (CST) exit exam as a condition of progressing. The effect of this change was later partially acknowledged by the Math department in the speaker's notes in one of their presentation slides in 2020: "The drop from 40% of students repeating Algebra 1 to 8% of students repeating Algebra 1, we saw as a one-time major drop due to both the change in course sequence and the change in placement policy." Finally, in conducting our review of SFUSD’s claims, we were unable to obtain any such “longitudinal data” they refer to nor could we replicate the repeat rate numbers quoted by SFUSD using data obtained via a CPRA request. We have deep concerns that SFUSD is claiming credit for student achievement that is either untrue or unsubstantiated by the data or both."

I started on twitter when the #mtbos had a contest for math teacher types to make a video critiquing Khan Academy. #mtt2k .... I *hate* twitter chats because indeed, you can write little bumper sticker sized answers to complicated problems in 280 characters but ... your crowd better already know what you mean. Sharing links to new math stuff though...

Duly note taht there never was any such research, and that actually, it does matter what the order is (there are some you can get away with switching, and some that you can't), and that actually, a whole lot of people *do* struggle with reading this stuff (as evidenced by actually measuring their speed & comprehension, as opposed to whether they post "it is easy."

However, it needs to be noted that how good readers read is not necessarily the same as how people learn to read. (Programmers: Do you code the same way that you did when you were learning it? Or are there a few zillion shortcuts that are automatic now?) We may recognize words by shape, but the letters still represent speech sounds, and *learning* what they are is rather important for learning to read fluently. There are also different ways the brain is wired for different people (f'rinstance, when females are processing language, it tends to go to more parts of the brain than when men are processing language).

Not going to defend stupidity here. However, drivers have many, many, many, many more cues and feedback RE: what they should be doing. The lanes and rules are set up and widely explained. It takes more jerkiness to be a jerk. And how often, exactly, do you see that happening? What percentage of the cyclists you see... oops, and the ones not noticed at all 'cause they're not interfering...

"But hey, if you want to go to the worst drug infested part of town that you can find, waving around a fist full of cash, and screaming "what n***** thinks he can take this from me", well, have at it. It's your life, and you are still responsible for your own behavior." THink about this. Why should getting to work on my bike on the best route I can find be equated to that? What are you saying about the roads and drivers ? -Guess what, I don't scream and flail when I'm riding into work... yet, you seem to be implying that even my mellow behavior is enough to incite behavior comparable to that of desperate criminals... I mean, how long a blind curve are we talking about? Seems we went from "passing going around a blind curve" to holding up traffic for five miles. Welp, actually, I'm not going to do that -- just as in the days when we had an old VW, up those mountain hills you pull over to let folks by who had a little more power. I think the silly laser lights are cute but don't think they're designed with traffic engineering in mind. "Not an expert but" -- if I were driving I'd be distracted by them in a negative way, and my eye would be drawn to the lines instead of the lines doing that instant "guide me away" thing that the painted ones do.

And why are they jerks? Imagine if a population were plunked down into an infrastructure of signage and roads... and the roads and facilities weren't actually designed for the vehicles in question. Welp, they *originally* were - bicycles were the reason for lots of roads to be built in the first place - but since then design has gotten carcentered. You pull up to a place where you're supposed to wait for the light to turn to green... only it never does. The sizes of lanes and visibility, etc. aren't set up for your vehicles. You're told "follow the rules of the road" but often that simply doesn't work. Which rules? Should you ride with or against traffic? How do you make a left turn? Most folks aren't going to go out of their way to research the stuff out... they're going to figure it out as best they can on the fly -- and be "jerks" sometimes doing it. Add to that some of the simply counterintuitive realities (like that riding against traffic is more dangerous)... I ain't sayin' it's a good thing, but I'm suggesting that drivers would fare no better.

Passing me so closely you endanger my life does have something wrong with it. The "if I can kill you, you should jsut get out of my way" attitude that you're projecting -- oh, in nicer words, but that's how bullies phrase it -- is chilling and all too common in driving and other human interactions. Major stress and inconvenience? Count the seconds. If your infrastructure is such suckage that it's significant, then it's the infrastructure that is at fault, not the cyclist.
