I think the article makes some good points, particularly with regard to having two ways of teaching nothing: first, by teaching nothing, and second, by teaching too much to the point of overload.
I think certain things definitely need to be explained in detail, and seem to fit well within a Western notion of proper education techniques. I have seen too many people, for example, throwing sloppy sidekicks. The kick has a certain way it is thrown, with the foot positioned like this, and the ankle like this, and extend and thrust the leg like this, and strike with this portion of the foot, etc. If this kind of detail is not given, then a sidekick is sloppy and a student will hurt himself if he ever tries to land it, even on a heavy bag, not to mention in a real self defense situation. All the basics need this kind of detail, or they are worthless. This includes all the kicks, stances, hand strikes, blocks, and footwork.
But other things in the Chinese martial arts simply don't fit well into a Western notion of proper education techniques, in my opinion. They are complex, and have many levels to them. A student begins by learning the gross movements, which are built out of properly learned basics. But the gross movements don't include everything. If a teacher tried to give the student everything, all the details at once, the new material would not be understandable. A student needs to grapple with the gross movement for a while, before he is ready for some refinement. And there may well be many levels of refinement, each requiring a prolonged period of work, before the student is ready for the next.
Many people think that every time they go to class, they need to be taught something new. But that is not true. Sometimes a student has taken a big bite, and needs time to chew, swallow, and digest before they take another bite. This means they simply need to come to class and keep working on the material, under the instructors watchful eye. Corrections are given where appropriate, but the student does need to wrestle with it a bit.
Often, new information is given when a student shows he is ready for it. This can come in the form of the student asking questions. When you are ready to ask the question, you are ready for the information. Prior to this, you don't even understand it well enough to ask the question. How do you expect to understand the material, if it was presented to you in a Western style lecture, with all the details given at once? You might understand in a superficial level, but you haven't really grasped it. You could probably regurgitate the material in a Pop Quiz, but that doesn't mean you understand it yet. It is too much info and you aren't ready for it yet.
Just this last Saturday, I had a moment like this with my sifu. We were discussing Tai Chi Chuan, which I have studied under him for almost nine years now. The discussion lead to some questions I had, and the answers suddenly opened my eyes and helped me to better understand the basic theory behind Tai Chi Chuan. But until I was ready to have that discussion, and ask those questions, I wasn't really ready for the information. It would not have meant much to me prior to this. (incidentally, my questions were sparked in part by comments that I had seen in some of the discussions here on Martial Talk. I guess you really can learn some things on the internet).
So I guess what I am saying is that when I hear comments referring to learning theory and technique and such, I think that some things in the martial art would be well taught with this approach. But others would not, due to the nature of the material. Martial arts are simply too progressive and ongoing for some of the Western teaching techniques to be effective, at least all the time.
And I would like to agree with many of the comments that others have made, in that many people don't want to work hard enough to learn real Chinese martial arts. So they don't. They are taught the gross movements, and that suffices as a form of exercise, which is what most of them want anyway. Those that are willing to work hard, and want to know the deeper levels of the arts, and who prove their worth and character to the sifu, will be taught the good stuff. But again, be prepared to work for it, and wrestle with it. Very little is handed over on a silver platter.
