- Explorations with Kojo
- Initial Steps in Programming with Kojo
- Programming Fundamentals with Kojo (uses ideas from Challenges with Kojo by Björn Regnell)
- Visual Patterns with Kojo
All except the first one are short books without any prose! These books contain small snippets of code for learners to try out, along with (constructionist) exercises based on code that has been previously seen/used by the learner.
Initial results with this format have been quite promising, and I plan to put out more such books over the course of this year.
