There have been several questions about teaching with microarray data. Kam Dalquist at Loyola Marymount University in Los Angeles has some interesting resources that you may want to look at. She is a biologist and she regularly teaches with a computer scientist. Much of what she does involves an analysis tool that she is a co-author on called GenMAPP.
Here is a link to information about her bioinformatics course.
Here is a link to a publication titled, “Improving the computer science in bioinformatics through open source pedagogy“.
