Make a Prototype and Test Your Design (1-1 1/2 hours) > Print/View All Notes
Students will create a prototype of their designs and solicit feedback from their classmates in this activity. Before the activity begins, consider creating or using an existing Edmodo.com account. Edmodo is a social learning platform where teachers and students can share information. Encourage students to log on to post their PSAs and view their classmates' PSAs. If you use the survey tool in Edmodo, you will need to input the questions from the survey on page 13 in the Engineering Portfolio. If you decide to work offline, have students look at posters or printouts of their classmates' PSAs. Be sure to provide students with additional copies of the survey from the Engineering Portfolio as needed. Each student should complete a separate survey for each PSA. Stress the importance of constructive criticism. Once surveys are completed, results should be given to the appropriate teams to help them evaluate their designs.
The following website provides a tutorial to help you get started with Edmodo: http://www.trschools.com/hsnorth/Edmodo/Edmodo_Tutorial.pdf
If this lesson extends beyond your normal class period, you may want to focus students on completing their prototypes in one class period and using the surveys to evaluate their classmates' PSA's during the next class period.
