The Norman reading for the week should be Chapters 1, 2, & 4. The 4th chapter is where the design ideas really get developed in concrete terms. Approach this book as a fast, light read. It can be dense, but just get a sense of what Norman is discussing. Try to come to class with ideas of what he is discussing.
Cassandra is presenting one of the readings, but there is a slot for someone to present the 2nd reading.
