Flexibility and willingly changing your plans to fit the needs of students. Allowing them to draw to music and share their thoughts worked best for them and it really worked.
I think EVERYTHING worked!
Can I go to ALL the music PDs next year?
Maybe next year students can play their pieces, record it, then read their reflection piece over the recording so it is all media based...no live performance. This would be good for students that are shy and do not like to present in front of people. They will still get to share their work at the assembly but in a different way, also it will cause for less keyboard malfunctions.
