Questions in the THCI cover the how-tos, demos and faults, but does not touch on correcting established Bad Habits of the intermediate and advance caster. During my formal music educator training day in the late sixties, a strong emphasizes was placed on establishing good habits and how to correct bad habits. The crux of the matter is: it takes 21 days/sessions to correct a bad habit but only seven days/sessions to establish a good one. Looking forwards to hanging up my shingle in the near future as a FFF THCI Instructor (hopefully pass the test in a few Weeks or Months), I have been considering how to approach the Bad Habit thing. I have used successfully in music teaching: Identify problem, Isolated problem, Establish exercise to develop good habit, repeat slowly the correct habit and then place newly learned habit into the overall scheme of things. My question to you is: (1), how do you approach correcting established Bad Habits in your teaching? (2), A fault can be the result of a well-established bad habit that needs to be corrected. How do you go about stopping the bad and introduce the good habit?
