As a music teacher, I have always struggled with assessing student performance standards like singing and playing instruments. Don't get me wrong, I do it every single day. Usually, I take anecdotal notes while everyone is working together. Individually assessing students takes a lot of time and what are the other children supposed to do while I individually assess? The music room has no desks, no independent books, and, frankly, it's hard to be monitoring others while trying to give your complete attention to the student you are assessing. Because of this, student portfolios have always been interesting to me but I have never really mastered how to make it work without a ton of additional things for me to do.
Within Class Dojo, each class has a "story" which allows you to post things for all connected parents in the class to see. Each student also has an individual "story" which allows things to be posted for just their family to see. Or for you to view for the purposes of assessment! A perfect, already organized and created by someone else, spot to record student performances!
I have just began to mess around with this feature but it requires no additional sign in for students and teachers or students can add things to their wall. Here is an example from second grade in which students were practicing creating their own rhythms with a new note, the half note. I traveled around and took a quick video of each student clapping and saying the rhythm they composed. It was a quick post by hitting one button and then it was available for both families and myself to view.
Our school uses Class Dojo quite a bit, so I love that kids already know how it works and could, just as easily as I can, add things in their own "story" or portfolio.
