I hear you, but I think it still worked. I was in elementery school in the 80s and learned logo (and had it at home on an Apple ][+). My teachers fit your description - they were most excited by the pictures we were able to make. None of them knew how to code. But that didn't keep the students from having the Aha! moments that logo provided, or from developing an understanding of key programming concepts. It was the interaction with logo that taught us, not what our teachers did or didn't explain to us.
