Reply To: Implementing my ideas
If you are not evaluating the outcomes of your instruction and considering how they play in their quarterly report card marks, then you must be marking purely on attendance or behavior. When I was teaching high school, I tried to hear every student individually once a quarter. You can have them play excerpts from the forthcoming concert, but you can include scales, arpeggios, a rhythmic exercise, even sigh treading.
Especially since you have an assistant teacher, this ought to be possible. If nothing else, set up a video recorder in a side room; split the playback with your helper.
Music is a PERFORMING ART. What grade they earn really ought to reflect how they play.
Does this make any sense?
