Students in the lab working with the annotated timeline of the Microarray Module.

Day 0:

• Students take microarray pretest.
• Homework assignment requires students to read handout and view the DNA Microarray Methodology Animation created by A.M.C. at Davidson College (http://www.bio.davidson.edu/courses/genomics/chip/chip.html).

Day 1:

• Teacher reviews the microarray uses and procedures using the animation or handout.
• Students work on the paper microarray lab created by C.A.Z. (Zanta, 2004).
• The teacher facilitates discussion of how the microarray measures gene expression, why gene expression is important, and how this relates to the cancer scenario of the activity.
• Homework assignment: Outline the wet lab microarray simulation procedure.

Day 2:

• Students work on the microarray simulation and analyze and record their results in groups.
• Teacher facilitates discussion of how the microarray measures gene expression, why gene expression is important, and how this relates to the cancer scenario of the activity.
• The posttest using same exam as the pretest, plus additional open-ended feedback on the entire unit.
