Reflection Questions

How do you see Marlene helping her students focus on the steps of the Engineering Design Process (EDP) as they move through the lesson?

Marlene uses posters (visuals) of the steps of the Engineering Design Process to reinforce the steps students are using. She also has students describe what happens during some of the steps. 

  • Marlene hangs up the poster that relates to each step of the EDP as students move on to that step. (0:35, 7:00)
  • Marlene asks students to describe what they do during the Imagine step. (0:40)
  • When she introduces the Plan step of the EDP, Marlene has students refer to the Plan duplication master. (7:00)

What strategies do you see Marlene using to encourage her students to work as a team?

By allocating time for group discussion, Marlene makes it clear that she expects students to work in teams. She gives them time to share and talk through their ideas, and gives positive feedback to teamwork. 

  • Marlene tells students that after they brainstorm individually, their goal is to share as a group to combine ideas. (1:31)
  • Marlene explains that their goal is to not just use their design, but to mix ideas to create the best design possible. (4:00)
  • Marlene gives groups designated time to share the designs they imagined and think about ways they can combine ideas. (4:20)
  • While sharing thoughts on their designs in a group, one student says, "It works because we put all of our designs together to make one." (10:00)
