Mike Petrilli points out the growing attention to using video in education and channels James Q. Wilson’s smart lessons. But Petrilli doesn’t really differentiate between whether video in schools should be used for accountability, improvement, or both. And that’s a key question.
If the purpose is merely accountability then there are less expensive ways to achieve that necessary goal. The real promise, it seems to me, is using video (and ideally interactive simulations) to train new teachers and help those on the job improve through coaching based on actual performance. That requires a set of investments not only in the technology itself but the supports to use it. But if you look at a variety of endeavors from training fighter pilots to professional athletes and a host of more commonplace professions in between this is not a great unknown, our field is just late to it. There are some companies in this space right now and expect more interest as the demand for observational tools and better training increases.
