I just ran across Jeff Chupp’s idea for Writing Hypertext Fiction in Markdown and thought immediately that this is also a fast and cheap way to prototype branching scenarios for courseware where the learner decides from 2-3 deterministic options and sees the consequences of their decisions.
No expensive tools needed. A little markdown is there. Some publishing pipeline steps. Mostly it allows us to focus on the learning content and getting the scenarios relevant to the learner’s performance environment.
