Innovation

Fiction. No real student, family or grade appears.

Drawing, panel 73: Design justification and device ethics.

Speed and safety in direct tension. More testing protects people and delays access for people suffering right now.

The people harmed by delay are invisible. The ones harmed by a bad device are not.

Drawing, panel 74: Engineering design.

Design is a loop, not a line. A failed prototype is an input rather than an ending.

Drawing, panel 75: Device and model testing lab.

Our first build failed on trial one. We had not controlled a variable we did not know was a variable. One trial is a measurement. Three trials are evidence.

Drawing, panel 76: Prototype evaluation CER.

Ours partly met its goal and failed on one measure. Writing both, with a specific proposed change, is the assignment.

Drawing, panel 77: Submit innovation package.

Model specs, trial data, CER. The honest version is more useful than the flattering one. That is the most repeated idea in this class.
