Observation Video – Elementary Math
This is a fairly straight forward classroom observation video aimed at helping teach our admins about gathering data. The focus of this particular video was engagement. I’ll be posting the pre-observation interview later.
This is part of our revamped professional growth process. It’s pretty interesting if you’re into that kind of stuff. If you are that kind of person, there’s a lot more information about what we’re doing here.
Bouncing Ball, originally uploaded by baslercast. It’s just another tool and it makes possible some quick connections that lead to bigger things. Connections are good- no matter how trivial they might seem. Last night I noticed Basler bookmarked the same water balloon catapult I did. I mentioned that in a comment. He responded with a flickr link to a water balloon launcher they made for physics last year and then I found the picture above, in which students took a photo and then explained the physics demonstrated by each picture (description below). What a cool idea and it seems to be part of a larger AAPT photo contest. It shows the period of time during which a ball was compressed against the ground after being thrown towards it. During the period of time which the ball is compressing on the ground, the ball’s kinetic energy is transferred into elastic potential energy. The ball is also dissipating some of its energy which results in the ball not bouncing back to its original height.
As a family, we have a tendency to wait until the last minute for most things. My oldest son, wanted Valentine’s Day cards with him hanging off a cliff. Somehow we didn’t get that done and it was suddenly tonight at about 7:00 PM. So, I had him hang off one of the stairs and shot it from above. No flash and crappy lighting but a decent enough shot for what we needed. Five minutes later and we had a cliff view thanks to Google. Another 10 minutes of Photoshop between the two of us and we were able to push the finished shot straight to Walmart for printing.I know but focus on the story. After I got everyone to bed, I was able to pick up 35 copies..09 cents a piece, not too bad and far better than the crap I’d buy in the store. I don’t want to make any sweeping generalizations, I just thought it was pretty impressive that we can do things like that in so little time, with so little effort.
All mobs are self selected and mobs often do very stupid things based on emotion – This post was inspired by some comments at the Edupunk panel at SXSW, which while disastrous as a whole, did have some good pieces. Granted, you had to look very, very hard.Mobs bully/attack other peopleor burn down building etc. but we’re talking Internet “mobs” here but they do so because people have gathered strength from finding other people thinking/feeling just like they do. I think the Internet and all the social media toolsfrom twitter to blogs makes it really easy to surround yourself with the echo-chamber, or a self-selected mob, and then it becomes much easier to start doing dumb things while still feeling like your ideas/actions have been vetted and approved by an unbiased crowd. I’ll also say that the Internet and social media allow you to do the opposite. That is you can surround yourself with vastly different ideas and people from very different backgrounds that will challenge your thoughts and ideas and help keep you from doing or continuing to believe stupid/wrong things. I think far more people do the former. It’s human nature. I try to fight it in two ways. One, I try to get lots of ideas from outside what I do. I try to broaden where my […]
