Reflection Questions

What strategies do you see Ann using to prepare her students for the testing they will be conducting in this lesson?

Ann posts definitions and handouts when she is discussing them so students are able to make a visual connection. She demonstrates testing procedures, asking for students to help with the demonstration when possible.

  • Ann has students practice lifting the model bag of potatoes (as suggested in the teacher guide), so they have a physical understanding of why ergonomics is important. She then posts the term ergnomics with its definition after they have experienced it firsthand. (2:43–4:59)
  • Ann takes the time to show students how to operate each simple machine station, sometimes bringing up student volunteers to help in the demonstration. (7:06)
  • As she references handouts, Ann posts visuals of the sheets for students to see. (13:21)
