Final Design Proposal (parts 3–4)

Facilitation guidance from the lesson plan — what to notice in student thinking and how to respond while teaching.
What to do
Part 3
Present your research
In this section students explain what components they are keeping in their design and what components they are not keeping in their designs based on feedback they received on Stakeholder Feedback Form and in their notebooks when they explained constraints and prioritizations around their design. If students simply need to see what they listed as primary, secondary, and tertiary, this is available on Decision Matrix. They should be able to use these three pieces of data to complete this section. Guide students to look back at these as they complete this section.
Part 4
Justify your design decisions
- Suggest students complete the first two columns first using what they have completed on Stakeholder Feedback Form and Decision Matrix and what they have written in their notebook around why they made the decisions they did for their design.
- Students have already spent time at the end of Lesson 14 considering the effects of each trade-off. Refer students back to their notebooks to find their ideas over why these choices and prioritizations were made.
Say, Though you’ve got some great ideas for how to improve your designs for our consumers, how could you use this way of thinking to evaluate and test designs that other engineers come up with for any proposed collision mitigation design solution? You will now use what you have figured out about contact forces and designing solutions and apply it to a new phenomenon scenario. This will be your final assessment of our unit.
