In my Engineering for Social Good elective I instituted "Lab Practicals" rather than formal exams and quizzes. Mastering Computer Assisted Design (CAD), via Fusion360, has been a constant thread throughout the class. CAD mastery was facilitated through weekly challenges organized in a Padlet "Shelf" where students would respond to a video tutorial by repeating it then making four alterations of their own. Students would then upload their product and explain their modifications in the shelf for all to see. Click here to see student work in padlet. This process facilitated mechanical/algorithmic knowledge of Fusion360, while integration of CAD into our projects and practicals promoted application of CAD.
Keeping the above in mind, for the Lab Practical of the semester I wanted to students to embrace the mission of service central to the engineering elective class while also applying their CAD content. Serendipitously, my freshman Biology class was in the middle of an activity where they were investigating fed blood cells under a Compound Light Microscope. Students were asked to use their phones to capture images of normal and sickled red blood cells. While many students were able to do this, pictures were shaky and the process of balancing the phone limited their ability to zoom in on the red blood cells and take quality images. I know devices exist to balance phones over microscopes for this exact purpose, but then the idea hit me: Why don't I have my engineering students partner with my Biology students and leverage Design Thinking? So that is what we did! and it worked out great!
