Here is a free copy of my new reflection letters (en français). There are 2 copies, one that just students and parents sign, and one that admin also signs. I find these are helpful as music teacher to have on hand because some of us have hundreds of students and it is a huge challenge to communicate sometimes when there are issues in class. I know these letters have improved my communication with parents this year in a big way.
In these letters, students fill out the "Aujourd'hui en musique" section with their side of the story. Then they have a chance to reflect on what they could have done better in this situation. I find letters are better received from parents when they already come with a solution on them. This was the solution comes from the student so it is more meaningful. I keep these letters in students files for when parents come to meet with me.
