I first heard about Dr. Robert Marzano's research at a Promethean User Group Conference in 2008. Over the past year I've heard more and more references to his research. Today I sit in an electronic gradebook training and the presenter said that Marzano's grading schema, that allows for individual "algorthimic" grading based on content comprehension that is irrelevant to time, is an option in their system; and that major, national, education leaders are supporting this type of grading.
I'm not sure a grading revolution is on the horizon but here's Dr. Marzano's website. Check out the free resources section. If you're not familiar with his research this will give you an idea of his findings and philosophy.
