2. Today Expert practices The data models The papers Onward
First design exercise

3. Experts test Experts are skeptical Experts simulate continually
Experts draw examples alongside their diagrams
Experts test across representations
Experts prototype concepts
Experts involve the user
Experts are alert to evidence that challenges their theory

4. Experts reflect Experts curtail digressions
Experts retain their orientation
Experts think about what they are not designing
Experts re-assess the landscape
Experts invest now to save effort later

5. The data models Tell us about the data models itself
what do we see?
Tell us about the process of findings the data models
Tell us about the value of the data models

6. The papers

7. Onward
Identify whether and how naming play a role in your system, and bring a printed copy documenting your findings to class next week
Be prepared to talk about your findings
Be prepared to talk about the process of identifying your findings
Be prepared to talk about the value of your findings

8. Onward
No class May 21
Read all of the papers listed on the web site for May 28
Prepare two questions, observations, or assertions about the papers and their overall content (printed, with name and student id)

9. First design exercise – structure
In a team of 4-5, spend two sessions of 1½ to 2½ hours each designing at the whiteboard
Be mindful of the expert practices
Videotape your sessions

10. First design exercise – deliverables
Produce a document detailing your design as it exists at the end of the second session
what are the design decisions so far
what is still left to do
no designing after the two sessions are done, incomplete designs are ok
Document, with seven short video snippets, when and how you exhibited certain expert practices while you worked at the whiteboard
DVD or memory stick (to be returned)
a document that indexes/explains the snippets

11. First design exercise – prompt
Design ClimbingRoutes, an app that:
allows mountain climbers to contribute new climbing routes to an ever-expanding database of such routes
allows mountain climbers to select, view, and navigate a climbing route
ClimbingRoutes is primarily meant to be a visual app

12. First design exercise – due date
May 28, at the beginning of class

13. First design exercise – grading
Design product
innovativeness of functionality
implementability
understandability
Design process
