Anthony Cody says:

while Gates and his employees constantly talk about growth and constructive feedback, they always seek to embed these systems in the evaluation process, where there will be huge consequences for those involved. 

I asked:

If I am wrong, and the new evaluation system described by Bill Gates really is all about feedback and collaboration, then why not remove the model from an evaluative framework? Make the sharing of videos voluntary and low-stakes. Provide teachers dedicated time for collaboration. Offer a variety of structures such as Lesson Study, Critical Friends, and Teacher Inquiry that have been proven effective at generating authentic reflection and growth.

If I turn out to be right, then smash those cameras, boycott those tests, opt out of the data systems, and refuse to be standardized and scripted.
