A couple of years ago I felt that there was too little discussion on pedagogics and teaching methodology in HEMA, a feeling I still have even if it is slowly improving, and for this reason I wrote three articles on this particular topic. This material I have also rewritten to some degree for a new book which also has several other chapters added already. The plan is to release a book with a mix of theory, pragmatic advice, tools and examples for teaching HEMA specifically, but also applicable to other martial arts.
You can find the articles here:
HEMA Pedagogics Part 1: The Pedagogics Pioneers & The Role of a HEMA teacher
HEMA Pedagogics Part 2: The implications
HEMA Pedagogics Part 3: How to create a good learning environment
