For science faculty:
Give it a try! Try also inter-disciplinary (e.g. writing in math and links to biology -- Math 107 last semester: Probability and Genetics)
What is the relevance to you of writing in math/science classes?
Reverse it: Why not put some (or more) math/data into non-science course assignments/reports?
A skill demanded in the "Real World" is: being able to combine writing/analysis with mathematical/numerical information in a coherent fashion.
. Numbers, functions, and graphs alone often are not convincing enough (nor, sometimes, even comprehensible without context).
. Written analysis without these, often not precise enough to be convincing (particularly in an increasingly information-based world).
.Today's world often demands both!
