Obviously it will vary by location and age. But I was in high school in the early 80s, and plate tectonics & Pangea were already in our text books. (And in my country it takes forever for stuff to make it into textbooks.)

I don't recall there being any controversy about it - it was used as the basis for a number of topics in geography (Indian Subcontinent forming Himalayas, bio-diversity and gene relations in Biology etc.)

I suspect the real lesson here us that education is far from consistent both regionally, nationally and historically.
