I've been teaching F# for over seven years now, both in the public F# FastTrack course that we run at SkillsMatter in London and in various custom trainings for private companies. Every time I teach the F# FastTrack course, I modify the material in one way or another. I wrote about some of this interesting history last year in an fsharpWorks article. The course now has a stable half-day introduction to the language and a stable focus on the ideas behind functional-first programming, but there are always new examples and applications that illustrate this style of programming.
For the upcoming December course in London, I added a number of demos and hands-on tasks built using Fable, partly because running F# in a browser is an easy way to illustrate many concepts and partly because Fable has some amazing functional-first libraries.
