A recommended practice is a one hour class
in which the black belts work with the lower ranks, a short
break, and a 30 minute to 1 hour practice period following
the class in which the high ranks may work together and the
lower ranks may practice the lesson they have just received.
All teaching methods must and should be positive and
uplifting in nature. Remarks that might be taken as personal
should be avoided. Of course, when danger is involved the
safe method should be explained quickly and directly.
