I’ve lived and work in both Japan and Taiwan and I can say unequivocally that FUNCTIONAL illiteracy is VERY LOW in both countries.
But then illegal immigration is not a problem in their country.
This might sound racist, but here’s a thought experiment — what if you just measured the WHITE literacy rate in this country?
That’s still 215 million people ( more than the population of Japan ).
I’d be willing to bet that the literacy rate would be just as high as theirs.
Here are graphs showing literacy rates by race and by income.
I have worked with students of all races and SES levels and actually, some of my fastest learners have been minory students of formerly homeless moms in Los Angeles! (Because fthey had no sight wird guessing habits to overcome.)
Most of my middle class students of any race have to untrained from guessing with nonsense words, I have a free game you can print out that makes both real and nonsense words.
Even more powerful than regular phonics is Webster’s Speller, it teaches phonics and spelling to a 12th grade level.
