Generally, teaching adults in a class format is kind of difficult.Adults have their own goal, we cannot really direct them in the direction that is not in their mind. As you may know, Yamaha Music Foundation has never been successful with adult classes, yet they have great success with small kid classes. Adults learn differently from 5 thru 12 years old children. Children do not have long span of concentration. We cannot make children to stick in the same activity more than 7 min. They will get bored and start goofing around. Adult, on the other hand, will not stop trying until they get it. If you make adult doing so many activities in one hour, they will get frustrated and confused. My advice is that do not go to fast with your teaching plan...Unless, your students are music major. Otherwise, those students will get upset...
Well, they're going to have to go in my direction because they will need to prepare to pass the piano proficiency exam. I will certainly take my time with the material so that the class can keep up.
