I worked with Google add-ons (gClass Folders, Doctopus, and Goobric, specifically) and Audioboo to record and assess performances by my students. In the past, I would listen to the students perform individually during class time for our concert music assessments. This usually took two full days to complete, and I never got to hear every student play everything or give them appropriate (and timely) feedback. I used a paper rubric and I would do the best I could to add some comments. Then, I would alphabetize the sheets so I could more easily enter the scores into the gradebook, enter grades, spend class time passing sheets back, and then I would find half of the sheets on the floor at the end of class. The sheets that actually went into backpacks probably disappeared there eventually, too. I know many teachers can relate to these challenges!
Solution: Google add-ons and Audioboo!!
