Some are working hard. Others are not. What does a teacher do? I have some students taking their guitars home every night. They are committed to this journey. Others still can't execute chords & recall chords in progressions. There is a huge gap in my classroom. It's alarming. I give students plenty of time to practice; I've been noticing patterns of using the time and NOT using the time. How do I motivate these kids to work at their skills!?
