Masters Wu Chien Chuan and Wabu Young in the picture. My own teacher states that Young Wabu was dominated by Wu Chien Chuan when they met and "compared" skills. Young Wabu was no doubt very skilled at Tai Chi. However, if we say that Wu Chien Chuan passed on all or even part of his skill (note I did not say his curriculum) it also raises the “how to gain skill” question?
There is a fairly extensive curriculum in Classical Tai Chi but it also matters what method(s) are used to study. Whether DVD or “online” Classical Tai Chi @ Teachable.com it also matters how the curriculum is studied. In the picture, Master Hwa is demonstrating how to do a posture to me. How did I learn to do the posture on my own and gain skill in it?
I first “Blocked”, then “Serialed”, then “Randomed” my practice of that posture.
Blocked Practice
Blocked practice involves practicing a Tai Chi posture (single motor skill) repeatedly before moving on to another skill. I had to isolate that posture on the DVD and nowadays online,not doing any other movements. In the lexicon of blocked practice it requires:
- Constant practice
- Fixed practice
- Drills
- Repetition (often described as "repetition without repetition" in contrast to random practice)
- Low contextual interference practice
Serial Practice
Serial practice involves practicing a set of motor skills in a specific, repeating, and predictable order.
Random Practice
Random practice involves practicing multiple skills in a mixed, unpredictable order, creating high contextual interference.
These practice schedules are often discussed along with what is called “Contextual Interference Continuum” ( C I C), with blocked practice at the low end of interference and random practice at the high end.
