Rigor is creating an environment in which each student is expected to learn at high levels,
each student is supported so he or she can learn at high levels,
and each student demonstrates learning at high levels (Blackburn, 2008).

What Happens If We Don't Tell Students It's Too Hard?


I love the story of George Dantzig that Cynthia Kersey wrote about in Unstoppable. As a college student, George studied very hard and always late into the night. So late that he overslept one morning, arriving 20 minutes late for class. He quickly copied the two math problems on the board, assuming they were the homework assignment. It took him several days to work through the two problems, but finally he had a breakthrough and dropped the homework on the professor's desk the next day.

Later, on a Sunday morning, George was awakened at 6 a.m. by his excited professor. Since George was late for class, he hadn't heard the professor announce that the two unsolvable equations on the board were mathematical mind teasers that even Einstein hadn't been able to answer. But George Dantzig, working without any thoughts of limitation, had solved not one, but two problems that had stumped mathematicians for thousands of years.

Simply put, George solved the problems because he didn't know he couldn't.
