To adapt PSI to CS4984, several changes or additions seemed appropriate. First, given limited GTA support, it is necessary for the instructor also to play the role of proctor and tutor, during office hours and during specially scheduled appointments. Second, given space limitations and the current lab situation for Computer Science regarding multimedia technology, it seemed necessary to hold class sessions in Derring 2069 twice, to accomodate two sections. Third, given the availability of computing resources, it seemed sensible to use electronic forms and electronic mail as much as possible, to encourage additional communication with the instructor and to avoid needless use of paper. Finally, given the lab availability and limited software licenses, it was arranged that students would be able to work directly with some software, but for other software would only watch a demonstration.
