Often when I am teaching or watching others teach kendo, I find that waza drills take considerably longer than the time allocated to them. This is because I and most other instructors like to break techniques down to their constituent parts and build up to the finished technique.
I am sure that you know the sort of thing I mean. For instance, men suriage men; where kakarite starts by attacking men at close distance, then motodachi responds by sliding his shinai up against the down stroke and when he gets that right he moves on to striking men in response. When it’s all working, both parties build distance and speed to approximate a real-time opportunity. Well that is the theory anyway.
What invariably happens is that at the most basic stage, the instructor notices fundamental flaws with posture, or footwork, or grip and then tries to correct that before moving on. This is of course a far bigger task than anticipated and sometimes, when the class has a high proportion of less experienced kenshi; it never gets out of the correcting basics stage. It could of course be argued that this happens because the teacher is asking students to practice new techniques before they are ready to try them, but as most kendo classes consist of mixed abilities, should we aim to stimulate the more advanced student or keep it within the ability level of the newest?
I personally am happy to practise the most basic techniques and can see the value of constantly repeating suburi and uchikomi drills for basic shikake men attacks, many instructors however are worried about losing students to boredom, if obvious progress is not confirmed by them learning more complex techniques.
