Editor's Notes
- For Forces and Motion, we developed about 20 learning Goals that we thought would solidify learning and address misconceptions. Here is a subset of the learning goals we want students to achieve in order to better understand velocity. (Again, velocity is just one of the big ideas for Forces and Motion. ) Rachel will discuss how we will measure the effectiveness of our activities during the research phase.
- For this activity, we decided we would like to have a slope tool. The idea is for students to pick two points on a line and find the slope between them. If they can get it right the first time, no scaffolding is required. If they do not get it right, we provide visual clues in the graph, table, and equation to help them. So the scaffolding appears on-the-fly, “just in time.” Demo http://smartgraph-demos.dev.concord.org/sproutcore/example-61-fancier-velocity.html#/shared/what-is-velocity After many iterations of design on paper, we handed the specs over to the developers, who then created a working digital version. After the product is deemed stable, we will test it out with teachers and their students for further review and improvements. We have been lucky enough to observe the local teachers and students directly. Afterwards, teachers provide feedback using an online survey.
