In a past life, I used to be a management consultant for some wafer chip manufacturers. Part of the fabrication process included some intensive cleansing protocols both mechanically and physically, so the facilities and also workers needed to be made 'pristine' prior to operations proceeding again. I helped design and implement a successful CBT (computer based training) program which served to be the first step in the on-the-job learning process for new workers, prior to serving an apprenticeship with a senior floor leader. Six months after it rolled out, we measured an improvement of almost 14% in efficiency, which is quite good considering the limit resources invested into the CBT and then rollout training.
So while I understand your point about physical complexity, I don't believe it is an insurmountable problem to address. The goal of the CBT was to give workers enough private 'lab' experience so they could learn more meaningfully when they reached the apprenticeship section of the training. Likewise, I am trying to do something similar here and the project could be intelligently structured between class time and home study to reinforce each other. Just one simple example would be to use the video to only 'chain' the techniques together into an list of consecutive actions. The actual instruction of how to perform each action (down block, stepping, turning, etc) could be reserved for in-class time.
As for wanting to teach everything in person yourself, I can understand that desire. I have a traditional teacher who does the same mostly, or he relies on his senior students to help teach. I myself see a project like this as an effort to extend myself and my knowledge and skill for the benefit of my students. Technology lets us do a lot of things which would have been inconceivable even 50 years ago, and I am inclined to use it intelligently and judiciously where it can be of help.
There are certainly some topics that can be learned in the way you describe, I do not deny that. I simply do not believe that martial arts is one of them. People like to say, "well you can learn THIS in this manner, so why not martial arts too?" Because not everything is the same, not everything can be learned the same way.
here's another example. How about math. You can take a math book, read thru it, grasp the concepts, work thru the practice exercises, and then if the book has an answer key you can check to see if you did the exercises correctly. There is a definite answer, and this lets you know if you have grasped the information correctly. That feedback is immediate. If you got some wrong answers, you have the information you need to go back and rework the problems to see where you went wrong.
With the martial arts, you do not have this. You are simply doing the physical movements to the best that you can according to how you perceive the video. You have no way of knowing if you are really correct, even tho it looks TO YOU like you are. You need to wait until you get back to class to find out, and maybe undo everything that you thought you learned because it was really all wrong even tho you thought it was right. It's easy to watch a video, fool yourself into thinking that you've got it, when you really don't.
You are relying on later classtimes to fix these problems. OK, why not simply use the classtime to teach it properly in the first place?
Don't look for shortcuts in teaching. I do not believe they exist. Intelligent teaching, effective teaching, efficient teaching, sure. But shortcuts to teaching, no.
