We were excited to learn more about Google Course Kit at InstructureCon but disappointed when we returned home and experimented with it. The biggest downside is that the submission does not display in Speedgrader. Our teachers# depend on Speedgrader. With Google Course Kit we found that the teacher graded it outside of Speedgrader. There were other negatives for us - We found the Google LTI does certain things better and the Course Kit does certain things better but it's seem silly to run both of them. It's too confusing for teachers.
