You must do THREE evaluations per group. You have 30 minutes total, so spend approximately 5 minutes asking questions about a prototype and 5 minutes writing the evaluations for that prototype.
You may use the forms provided in class to take notes while visiting the prototype demonstrations, but you need to transcribe your evaluations to the » Google Form « by the end of the day. If you presented your prototype, do not forget to submit your images to Canvas by the end of the day as well.
Your prototype grade depends both on your prototype images and your evaluations of other students! Keep your feedback constructive and professional, and provide more comments than "Looks great!" on the evaluations. Be specific about what you liked, and what you think could be improved.
