Guest-hosting on The Posner Show, Gabriel talks with Sarah Senk, a professor who studies trauma, about the shooting in Colorado and the immediate calls to not "politicize" the massacre. Gabriel and Sarah compare the shooting's aftermath with the reaction to another "national collective trauma," 9/11. They next discuss technology in the classroom: Has it improved pedagogy and the learning experience, or is it all hype? Gabriel gets sentimental for a pre-technologized education, but concedes that technology has its educational uses as well.
