Same here, although I went to elementary school in the 80s.
However, in one of my university computer science classes, I think we talked about parse trees in the context of English senteces. I don’t know if that counts.
Never learned it…didn’t even know of it until well after I graduated high school.
Elementary school in both New England and Florida, mid-to-late 80s.
I would have loved diagramming.
When I was about 7 my mom saw that I needed something to do, other than browsing the Childcraft Encyclopedia and memorizing the poems, so she showed me how to diagram sentences. I loved it! It was like doing puzzles.
My elementary school did teach what I see is called Reed-Kellogg in about 4th grade (1963), but only a brief, single lesson.
Me too!
I learned constituency trees, but only at university (late 80s).
No sentence diagramming ever, k-12, central Indiana. Loads of spelling instruction, 1st-7th grades, phonics through third grade, and grammar and composition through 11th. Senior English wasn’t required back then (1978 graduate).
I didn’t know until now that it was called “the Reed-Kellogg system” but I learned about diagramming sentences in elementary school–I don’t remember exactly which grade–but probably sometime around 1980 or so in Cobb County, Georgia (suburban Atlanta).
