That’s simply not true, fortunately. All public schools are to follow common core standards and that includes phonics (sounding out words) over sight words and certainly over context guessing. Going contrary to the core is possible, I guess, but certainly not the norm. If you’re curious, the debate was mostly settled in the 90s, during what my PhD advisor called the “reading wars.” Well, mostly settled… sight words still have a place in reading, especially when a word is contrary to its phonics. But basically, policy has prioritized phonics since Clinton, with to only some revision under Obama. That’s not to say Americans aren’t dumb; doesn’t mean much if standards aren’t met. But it’s not as simple as saying we’re taught incorrectly. I could give a variety of reasons, although Lemmy users can probably guess poverty, politics and capitalism are pretty central to a lot of it.
