The best resource I am aware of is Gregor Kiczales’ course How to Code: Simple Data. The course is available for free through edX.

Kiczales Course Structure

The two most important parts of the course (from my point of view) are:

• Module 1b: How to Design Functions. The design process.

• Module 3a: How to Design Worlds. Big-bang.

How to Design Programs Videos

Professor Matthew Flatt has a long list of videos about Racket fundamentals. Of course some of them are slightly different from what we learn, but overall they teach the difficult fundamentals. No graphics when I checked (Fall 2021).

Other Resources

Signing up for a free online course is too much commitment? You could browse the YouTube playlists of Professor Kiczales. The first video of Summer 110 Weeks 3-4 is an introduction to big-bang.
