I think what we are missing is the fact that a child should learn Torah in their own language. It is well known that the Chazon Ish did not put emphasis in learning davka in Yiddish. At that time, there were people who could not speak yiddish, so he said they should be taught in their mother tongue, Ivrit. I have heard the following quote, “A cheder is not an ulpan”.
Therefore, nowadays, besides in the main chassidish centres and ‘American’ yeshivos, ivrit is the language of Torah learning in Eretz Yisroel.
I know many people from yekkish/litvish homes, i.e. english speaking, who learned in Yiddish schools in London (Stamford Hill, where there are no non-chassidish schools anymore), and they can’t read and translate chumash into English. They can translate into yiddish parrot fashion without any understanding at all.
Of course, we want children to open up a hebrew Sefer and give a dvar Torah at the shabbos table, but better to understand your learning in the classroom.
