Great idea! I believe that teachers feel like data is mostly about grading them and their students, and not about improving the educational experience. Some "Get it" but most either lack the tools, the support, or the mindset.
Then throw in classes with 600+ students requiring multiple teachers. Trying to align fairness (rubrics), plagiarism (tools like Turn-it-in) and the uniqueness of teaching style is difficult.
We'll, I think it is more about teachers being overloaded with the minutiae of data that causes them to lose focus of the bigger picture (education). Actually, in my opinion, education has lost focus on the bigger picture of education and may have never really had it.
This. Solutions like these are good in that they'll help schools get the space they need to be able to consider good reform, but said reform isn't a conversation that Americans seem capable of having.
