When the experts say that algebra should not be taught in 8th grade, and the experts say that guessing at words instead of sounding them out is a better way to learn to read, and the experts say that calc can be replaced with 'data science' which is actually just data literacy, and so on and so forth, I'm not really interested in how the precise definition of 'experts' actually refers to something about 'growing our collective knowledge'. I'm more interested in staying away from all that. It's a fun gotcha to say things like 'well evidence either is or isn't', but it doesn't change the material reality of who's doing what and what they're likely to be doing in the near future. Public schooling is fucked, the group of people saying 'listen to the experts' is the group of people making it worse, a lot of it is explicitly political, and your best options for guaranteeing that you avoid it are homeschooling or parochial school, regardless of what words and rhetoric can be said about it.
