But very few places seem to be able to make it happen. I know one example where carpentry and algebra teachers got together to try to work to the same goal. But it is the only case I know. It's so hard. Try mixing computers, biology, and mathematics all at once.
Time is major factor.
And if you have time pressures at the college level, think about moving this challenge down to high school. Time is a real problem there, for both teachers and students. Teachers hardly have the opportunity to talk to others in their own discipline, let along take a year to be comfortable with the vocabulary of another field. Now with all the pressure of standards, teachers are feeling as if they are getting squeezed from every direction. And still not very much new gets accomplished.
