10:40 am. Dr. Kelley will be administering course evaluations. I appreciate your objective feedback on the course re. things you appreciated and ways to improve. Realize that these evaluations are completely anonymous; all written comments are retyped, so that I do not see the handwriting. I also will not see these until late June, so they cannot positively or negatively affect your grade. I especially appreciate constructive written comments, as the bubble sheet questions provide just numbers but no specifics.

UAMS needs to fill summer
positions in their USSEP program for this summer. The program provides instruction in the basic
sciences during the summer for minority students. Not only is the instruction free, but they
are offering a stipend. If you have
minority students (especially freshmen or sophomores) who plan to apply to
medical school, this is a tremendous opportunity and I hope that you will make
them aware of it. Not only that, but
they will likely come back to UCA in the fall as better science students in
your classes. The necessary forms are
attached or you may have them contact me.

sciences (e.g. biochemistry, immunology, cell biology, etc.). Sign-up sheets are available in the Chemistry
Dept Office (LAN205) or in the Biology Dept Office (LSC180) or students can
contact me @ 852-2655. I
have attached an seminar announcement flyer, so please make any
students you think may have an interest in biomedical research know about this
event.
