This week I viewed the Chapter 13 video: Solving a Logical Reasoning Problem. The students worked in small groups to find the minimum travel time in a challenging word problem. Students then presented their solutions to the class using a document cam or SMART board. Overall, I think it was a good lesson. The students seemed to work well together in trying to solve this problem and they did a good job of explaining their solutions and reasoning methods to the class. (I just wish I could get a copy of the problem myself, I want to try it!)
However, I thought that the technology use was weak. The document cam was moderately useful in showing how the students worked out the problem on paper. I’m not sure this was helpful to class overall since I thought it was hard to see and understand the drawings. The first group that used the SMART board merely drew lines and labeled with letters—this could have been done with any old whiteboard. The last group attempted to act out their solution by moving the pictures, but I don’t think this contributed much to the discussion. I think a simple line diagram like the previous group drew was more effective in communicating their solution.
I don’t think the technology used was required for the lesson. I think it would have been just as effective with a simple whiteboard. Unless the students are really going to do something with the SMART board, I think it’s more of a distraction or a toy. I think this video was a tiny bit embarrassing; if I were in a classroom lucky enough to have a SMART board and I was going to make a video of its use, I’d certainly showcase it a little better!
