While I have created my own way of teaching/curriculum for my two main arts, and have mid way created my 3rd. Currently I am on the rewrite of my 2nd main art. So I don't mind sharing and I'll try and keep it brief.
I teach what we call American Karate but that's for marketing purposes, it's really American TKD. We use the TKD forms but other than that we have no ties to Korea. All of my instructors in karate and TKD have all been American and had no ties to the mother countries so it is an eclectic art, in our parent association we are free to add and subtract what we want (if you want to test in the parent organizations test then there are minimum requirements to be met, but we are given a lot of leeway). What sets us apart from others in our association is in two areas.
1) Self defense Early on I start teaching my students (mostly kids) about weapons defense which is based on my FMA training using material from my FMA class. Also I teach a them sweeps that are influenced from the FMAs or Silat, and for the older kids they get into some locking and fighting from the ground. We'll do some ground work but it is mostly trying to kick or defend from the ground, and we do some defenses against kicks etc. etc. which they defend against, thus taking the person to the ground etc. etc. But the goal is to either fight from the ground and get up or take the person to the ground and get away not wrestle on the ground with another person.
If any thing that is (lack of ground work or rolling) the biggest area my curriculum lacks in. We also are non competing (tournament) focused.
2) Weapons work. Our Kobudo program is also different because a lot of what I teach, I teach from the concept of what I call compound learning; using the same drills, techniques or training concepts over several weapons. So once again my FMA training is grafted over to the Kobudo program (this is the 3rd art I teach and the curriculum is currently on hold, as I'm rewriting my FMA curriculum). This class is generally reserved for the older students in the TKD program and the FMA program.
My FMA program will take longer to explain.
I teach what we call American Karate, too, because you have to call it something. Can't just call it That Martial Stuff We Do because that would look kind of silly on a patch.
