answer:If I were taking an hour piano lesson every day Monday through Friday, and demonstrated that I was learning during the class, and was walking out each day having mastered a small skill, then it would make sense. And if I couldn’t show by the end of the day that I had it down, the teacher told me to go finish mastering it at home, that would make sense. That’s what the teacher in Texas is doing, and it is a breath of fresh air for teaching. But a piano teacher doesn’t get you for an hour every day, they get you for an hour a week. And learning piano is different from learning arithmetic. Piano requires a lot of muscle memory and practice even at the most proficient levels. A 3rd grader should not have to practice single digit addition every week like a concert pianist has to practice scales.
