Or try the converse, in the UK almost all foreign language content is still dubbed.
Then for foreign language (French and German) classes in state schools in England around 1975 onwards:
We'd often have around 30 pupils.
Time was spend on learning vocabulary and set phrases, but mainly in the written form.
This would be from around age 10 (French) or 13 (German).
It was the first exposure to grammar concepts (verb, noun, etc).
Little time was spent on speaking the languages.
At the end of this most of us we still incapable to speaking the foreign language, let alone being literate in them!
I'm not sure to what extent it has improved since.
