Reflection Questions

What evidence do you see that children are weighing the impacts of variables as they make decisions about improvement ideas?

When talking about the improvement ideas students are clearly thinking about the scoring system and how changes they make might be reflected in their total points. We also see some interesting discussions about trade-offs. 

  • When discussing improvement ideas we see students talking about tradeoffs for changes they will make. For example, one group mentions that if they use an area with rocky soil instead of organic soil so they won’t need to do any compaction since that type of soil will hold the dowel more firmly.

  • When reporting out to the class, we see one team explaining how they took three points off their score. They are able to differentiate that it was partially due to increasing weight it could carry and partially due to lessening the amount of soil compaction. (12:40)
