Discussion: Learning Mathematics from the Study of a Video Clip
Iíd like to encourage you to spend some time working on the problem posed in one or more of the tasks Iíve laid out. These tasks have been designed to provide people with opportunities to learn mathematics through working on problems that are similar to those teachers routinely face in their work.
You will notice that some of the problems Iíve posed are closely tied to the things said and done in the video segment while others draw upon the video to launch mathematical work that can be pursued with little reference to the video. In those cases where close viewing of the video seems necessary or useful, there are control buttons on the video viewer that you can use to navigate the video (pause, fast forward, rewind). You can also use the time code in the bottom right-hand side of the viewer to reference particular moments in the video. For example, if you wanted to refer to the place where Keith tries to explain why Riba disagrees, you might point people to the portion of the video starting at 02:39:00.
Iíve started one discussion thread for each task. (Click here to go to this section of the keynote) Please join in the discussion for the task(s) you are most interested in exploring. As you work, try to pay attention to the kind of mathematical work the problems entail, and the mathematical reasoning and ideas you are using as you try to address the questions. We will talk about these observations in another discussion thread, further on.
