                                                        1. Each student will choose a topic area and at

     students. The student will be graded for both
     content and presentation quality.

     questions for each speaker, and will be
     graded on both their understanding of the
     topical area and their critical analysis of the
3.   We are reserving the possibility that each
     student will also undergo a highly structured
     20-minute oral examination on the overall
     course material. Part of the motivation for
     considering this is to improve student
     performance at oral exams.

It should be noted that the subtopics that will be
covered in each offering of the course will
depend on the availability of faculty with the
requisite expertise, stars, and students with
specific interests.

               OTHER IMPACTS

Both the introductory lecture for each topical
area and the "star" sessions will be open to
Computer Science faculty and students, and to
healthcare professionals in the region who are
interested in Health Informatics. External
participation will be facilitated using audio and
document conferencing techniques. In this way,
the course will foster collaboration with
professionals in the health system, and provide
an educational opportunity for interested health
