I wonder where your lessons for BASIC and LOGO came from. I've got to think that there's a wide range of quality in lessons and lesson plans. Or at least some lessons are intended for a certain age group or emphasize one type of skill over another.

I'm reminded that when I was taught LOGO in the 70s it was in a class where there was about a 3 to 1 student to teacher ratio and the lessons were far from self-paced. Maybe THAT'S why I have such great memories. It's 'cause I had someone right there to answer questions. And my memories of learning LOGO in the 70s was it was very much like an American Montessori experience. The "teacher" introduced a concept and you got to play around with it for an hour. Then there would be a new concept followed by more play. And as I mentioned, if I found I couldn't do something I wanted to do, the teacher was right there.
