Here's how it's going to work:
I will be using google classroom with each of my classes this year. Students will need a google classroom account AND a Seesaw.com account. SeeSaw is great because it can be accessed on any device. There is a SeeSaw app for smart phones...but if students don't have a phone they can use computers with webcams or chomebooks.
I will assign playing tests on google classroom with specific directions. Students receive a link to a google form which contains instructions for the test as well as a rubric where students will grade THEMSELVES. Students will be instructed to grade themselves carefully. They must PROVE and justify their grade by performing their playing test in SeeSaw. I can then review any video and see if I agree with the rubric students submit. The great thing about SeeSaw is that it creates a portfolio so students can go back and review any playing test. They can see their progress throughout the year.
