Dan Meyer‘s recent post on how to deliver a “3-Act” lesson really got me thinking that more teachers should be posting videos of themselves teaching. The main point about having a math blog is to become a better teacher. Right now, the way the we achieve this is through sharing ideas, giving and receiving feedback from other bloggers, and reflecting on our practice. Is it possible to go further by recording yourself, and then getting feedback on the actual delivery of the lesson? I feel that I continually create lessons that I have such high hopes for, but rarely ever live up to the amount of time and effort I put into creating them. I think being able to receive feedback on lessons you taught, as well as, seeing how other “expert” teachers deliver a lesson, would be so helpful. It’s one thing to create the perplexing lesson, and I feel like this is getting easier since joining the math blogosphere, but it is entirely different thing to implement it. Steve Leinwand proposed an idea at NCTM 13 of recording teachers every month and then at the professional development meetings, randomly watch one of the videos as a department. I think this would be a great idea, but I also think it would take the right department, and a good department chair to lead the discussion so that it is productive. That is why I think putting the videos online would be much more productive. First, the audience is much more motivated to give sincere and meaningful feedback. Second, it is easier to give and take feedback when it is written down because you have time to process it. If this is already going on, someone please tell me where and how I can join, but I think this is the next place the math blogosphere can go. Is this something other teachers would feel comfortable doing? Is this something that teachers would even want to do? And if it is, what would be the best way to do it? Let me know what your thoughts are on this.
