One thing many who do not have a LC education are missing (some with an education as well) is basic language skills. Many of them are simply unable to express themselve better than a mumble jumble of vague pronouns. I have seen some very bright people unable to ask simple questions without needing to explain themselves 4-5 times. I come across this issue not only with business and practicle questions but also when people ask halachic shaylos and I have a very difficult time giving them an accurate psak. I need to pry the real question out from them. The same happens when they are learning with a chavrusa.
This has nothing to do with the English language, but with any language. Someone who can express themselves in yiddish can them adapt to english. It does not make a difference which language it is. Teach english, teach yiddish, teach ivrit, teach lashon kodesh, teach aramaic. Something.
Which is exactly what I said here (emphasis added):
All of the above notwithstanding, I don't think that the term Chinuch Al Taharas Hakoidesh means no English or Math! I absolutely do think that kids should have proper language skills (and if they have an appreciation for that in one language, that will translate automatically to other languages), and basic math skills (which is definitely a part of Torah - my SIL actually created a Torah curriculum through sixth grade that gives math skills, to the extent that upon completion a child can actually create his own Jewish calendar).
This is not a L"C issue, on the contrary, it shows VERY POOR L"K!!!! 99% of הבנה on the basic level is simply being able to read the text properly. I recall how I once gave my son an assignment to learn the first Perek of הלכות חובל ומזיק on summarize it for me in his own words, as a consequence (what some people would call punishment) for something he did. He came back to me with something written, which I had a hard time making heads and tails of. When I asked him to show me what he just wrote in the text, the first thing we discovered that he summarized קיצור שו"ע rather than הלכות חובל ומזיק in משנה תורה להרמב"ם. But then when we tried to go through the text, I had him explain it to me, and where he explained it wrong, it was simply bad reading, which was corrected by having him analyze the logic of what he was saying, and then finally realizing that he just read it wrong.
A child, by the time he is bar-mitzvah, should be fluent in Kitzur Shulchan Oruch (except the halachos which are irrelevant at that stage in life). As long as that is not the case, where's there time to waste on L"C?
