Hiya Nick, actually my first iteration of commenting on Michelle’s liquid syllabus up (blogpost of mine a few months ago) said sthg similar: let the syllabus be changeable (I already used to do syllabus as google doc but students had never edited it – i do let my teaching emerge, tho, so assignments, deadlines, evaluation criteria, and in-class activities change as i teach in the semester.
One pair of students made their liquid syllabus as a blog with blogposts for each assignment so students could comment and give feedback on assignments. I love that they reached this on their own. But you’ve taken this all further into the notion of forking which i really like (someone made a similar comment on twitter btw – forking seems to be the word of the month?)
