> it's actually not that complicated, just look at what other schools in the country do, or what these did before the change

Except that you have not done that. Where are your data? Did you make sure that the group you compared are representative to each other? How do you correct for all the differences in state (unemployment level, diversity in education, political orientation, level of rurality, ...) that all have an effect? ...

So, no, it is objectively pretty complicated. You should have taken advanced data science, you would understand better that just comparing 2 states is very very naive to draw conclusions.

> remember, you are the one who started these word games by renaming the slow curriculum the normal one, when the normal one is the one they had before these changes, the one which reflected the norm (hence the name) in the US

In fact, I was not the one who started: the measure that is in question in the article has been proposed because people have done a study (a real one, comparing the numbers, you know, the thing that you say one should do before saying if it is slow or not but that you did not do) and concluded that there was a problem.

The document is 1000 pages long, of course it covers the elements that support their proposal (and you should agree with that as you say it's not complicated). These elements were themselves critized (maybe correctly), so it is funny to see that sometimes the argument is "their base study is badly done" and sometimes it is "I claim that I know what is 'slow' or not, without study, which is fine because if someone says it's not, they have just renamed without study"

If a team came up and say "we had a look and concluded that we should replace algebra by data science" and you just say "naaah, I have ZERO study on the subject, but I want to believe that algebra is fine", when someone says "but the point is that algebra is not fine", you cannot say "you haven't done a study": YOU are the one who pretend that the measure is not supported by the data, while you are the one having not looked at the data.

(and don't get me wrong, it does not mean that the study done by the people who proposed these measures is perfect or even correct. On the opposite: such study is difficult. If you now claim their study is invalid, it just show that 1) it is true it's complicated, 2) you don't care about the reality as you didn't even consider that they may have been backed by a study, you just assumed there was none because it was more convenient for you)

> also, the last paragraph of your post presents a false dichotomy: creating a new class doesn't require cancelling advanced algebra (advanced advanced algebra?)

What are you talking about: I'm not saying they had to remove advanced algebra in order to introduce advance data science, I'm saying they decided to replace something that they think is not challenging, engaging and useful enough by something more challenging, more engaging and more useful.

And if you think "aaaah, it's awful because before there was algebra and now there is no algebra, so it tortures the poor students who like algebra", why were you not crying about the poor students who like data science that was "canceled" before this proposal.
