I teach Mathematics, Physics, Astronomy in a German "Highschool", well comparable with a college somehow.
None of my colleagues uses LaTeX unfortunately, rather Word or OpenOffice/LibreOffice and my oldest colleague provides worksheets with a typewriter and is literally glueing images and texts together, before inserting it into the copier ;-)
I have done multiple presentations on Physics and Mathematics curricula topics with beamer, for its easy reusability (topics do not change that much or often)
