Clickers & more

So I love the clickers. I've always thought they were neat and wanted to use them but have now made the time to and gotten a great response. I used it more as a formal assessment as opposed to the express poll stuff, but could see myself using both in the future.
Here are some thoughts on the activity we did after the clicker training. I feel like it was interesting information and that I would potentially use some of the ideas but that there was little in the way of hard examples or "stuff you can use" to borrow a phrase from the Beaver Creek Conference. For example, not giving any zeros to students was an interesting idea that started some great conversations, but I believe the paragraph ended something like. A staff got together and discussed some alternative ideas, the principal picked the best and implemented them....WHAT ARE THE IDEAS!!! I would love to know, because every time I tried to think of something I could easily find the reason it wouldn't work.
As far as A, B, C, D, F vs 1, 2, 3, 4. I don't believe that I understand how they are really different. Maybe in a generation or two the thought pattern will change but I have many friends both in teaching and as parents of school aged children. And while they use the number 1 in conversation, they use it in a way that is completely interchangeable with how they'd describe an A. It would be interesting to see a study of today's high school students and see if they see and A as a 1 and a 1 as an A or not.
