Kirk Carapazza & Mallory Noe-Payne:

The next time you pull out your checkbook to pay that hefty tuition bill or pay down your student loan, consider this: there are countries where students pay nothing to attend university. Denmark, Sweden and Germany, all have tuition-free college.

WGBH Radio’s On Campus team wondered how these countries do it, and if there are things the U.S. can learn from their model. Their search to understand how German universities keep costs down and quality up began in the Rhineland.
