The Chicago Tribune reported National-Louis University is offering a Groupon today for 57-percent off a three-credit graduate-level introduction to teaching course at its Chicago campus. (Regular tuition for the course is $2,232 but Groupon will offer it for $950.) According to Groupon’s communications director Julie Mossler, this is the first time an academic university has used the website as an effort to boost student interest. "There are all kinds of factors in the K-12 world that are really discouraging teachers and people seeking teaching degrees," said Jocelyn Zivin, NLU’s vice president of marketing and communications. "We'd like (potential students) to understand what the realities are, whether you are committed to this profession...and see if you have what it takes."
