Why Should You Try a Thinking Classroom?

Overheard in calculus class this morning (day 2 of full thinking classroom):

• "I don't think this is going to work"
• "Why?"
• "Maybe we can try..."
• "Shouldn't that happen because..."
• "What does the graph look like?"
• "What if we..."
• "Can you verbally explain what you did?"
• "Can you tell us what we did wrong?" (one group to another group)
• "We were real mathematicians today"
