Aha! is a smart camera that gives teachers the power to easily capture video of their classroom to investigate specific questions they have about their teaching practice.
Teachers are given a lot of standards and are being increasingly evaluated based on quantitative measures. Reform leaders like Bill Gates has even begun collecting thousands of hours of video to determine how teaching can be scored and best practices extracted.
I believe that the availability of inexpensive hardware and open source technologies make it possible to flip the script a bit. What if we enabled teachers to evaluate themselves, privately, without judgement, and to do so on a daily basis. An iterative and reflective approach to teaching breaks with how we typically think about teaching and stands to increase the pace of change.
