While it may be bullshit that America is currently falling behind China and India, the fact that the majority of American adults are not functionally literate is a serious problem. Americans can never ever achieve any real scientific literacy at their current reading literacy levels. It's flat out impossible, and the fact that the authors of this article are complaining about scientific literacy out of context shows you that they don't know shit about the causes of the various problems within our schools.
Hell, roughly half of American adults are so illiterate that they can't even read the one sentence instructions on their medications. That's why you have stuff happening all the time like this:
"A two-year-old is diagnosed with an inner ear infection and prescribed an antibiotic. Her mother understands that her daughter should take the pre- scribed medication twice a day. After carefully studying the label on the bottle and deciding that it doesn’t tell how to take the medicine, she fills a teaspoon and pours the antibiotic into her daughter’s painful ear."
To quote the most recent report on health literacy, "90 million adults with limited health literacy cannot fully benefit from much that the health and health-care system have to offer."
Despite all the media jokes about people researching their own diseases, the fact is that only roughly 10% of American adults are even literate enough to read popular articles about medicine, and only ~3% are able to actually understand the academic literature. When they say that 90 million adults can't participate in the medical system, they aren't talking about adults who can't research their own symptoms and medications and help the doctor on collaborating on a diagnosis and treatment; rather, they're talking about people who literally can't even do what their doctors tell them to do. Roughly 25% of all doctors visits result in the patient not doing what the doctor tells them to do, and a large percentage of the time it's because they literally can't understand the simple instructions the doctor is giving. We spend roughly 1.2 trillion per year on the health system, which means that up to (but probably significantly less than) 300B of that is going right out the window due to poor adherence, especially since those with low adherence have good outcomes roughly 26% less of the time than those with high adherence, so they end up costing a lot more money in the longrun. I forget what percentage of low adherence is due to literacy/education, but I know that it is one of the largest factors.
The fucked up thing is that "among those scoring in the lowest level on the prose literacy scale [1st-ish grade level], only 29 percent reported they did not read well and only 34 percent reported they did not write well. The majority of those performing at this level perceive their reading and writing skills to be adequate. Among those in the next highest level [4th-ish grade level] the results were even more surprising, as only 3 percent said they couldn’t read well and 6 percent said they couldn’t write well (Kirsch et al., 1993; see Chapter 2 for more information on the NALS)."
If you ever actually go into a real science classroom you'll see that if the teacher actually tried to teach science it would be a complete waste of time. Virtually none of the kids would actually be able to understand any of the lessons, let alone transfer them to real life situations. And while it's true science textbooks and the way science is taught is terrible, the vast majority of students aren't going to become scientifically literate no matter how you try to teach it.
