U.S. Education Secretary Arne Duncan continued his tour of the Southwest on Wednesday with stops in Arizona and New Mexico to discuss education technology and college affordability. Duncan rode the bus with middle-school students and discussed the transition to the Common Core State Standards in speaking to teachers and students. "We think a lot of the tests you take -- fill in the bubble tests -- are not that great," he said. "Our hope is that the new tests will test more of your critical thinking skills. More thinking, more problem-solving, working together and less rote memorization," Duncan added.
