Philip Sadler-Designing Engineering Challenges

Below: The importance of doing multiple iterations against nature..

• Design iterations should be short in length- 15-20 minutes each- so that:

  • Students can make multiple iterations of designs

  • Students are not overly personally invested in a particular iteration

  • Tests should be against nature- not against other students

  • Teacher should provide a prototype design that works- but just barely- so that all students have success and are able to make improvements
