The Design Exercises on this site, like the Design Explorations in the book, are appropriate thought exercises for designers which should help them to think outside their disciplinary training and focus on the collective process of inventing the medium.
For students, these Design Exercises are appropriate for short weekly assignments to develop the habit of critiquing design with carefully chosen words and specific examples. A good way to organize this assignment is to have students submit a 50-200 word text and an image with link to an online video, app, or live website as appropriate, and to have them look at one another’s submissions by posting them to a shared page, like a wiki or a page generated by php from a shared folder. They are a good complement to courses that also include substantial hands-on project development.
The Design Explorations in the book can also be used in the same way but they tend to be more open-ended and time-intensive group activities, suitable for an in-class design lab or longer-term student project development.
