reading reaction

Reading notes will include questions, comments (what was interesting or unique, 

correspondence with other readings), opinions, general thoughts/reactions regarding each of the 

readings assigned for the week.  Copied sentences from the readings will receive no credit. 

These weekly notes will vary in length according to the number of reading assignments, and 

should average about two double-spaced pages per reading (not including any summary of the 

material you may choose to include in your notes).  Please have these prepared for use during 

lecture.
