reversely K. literacy Bill Drayton believes we’re in the middle of a necessary but painful historical transition. For millenniums most people's lives had a certain ___1___. You went to school to learn a trade or a skill-baking, farming or accounting. Then you could go into the workforce and make a good living repeating the same skill over the course of your career. But these days machines can do pretty much anything that's ___2___. The new world requires a different sort of person. Drayton calls this new sort of person a changemaker. Changemakers are people who can see the patterns around them, identify the problems in any situation, figure out ways to solve the problem, organize fluid teams, lead collective action and then ___3___ adapt as situations change. For example, Ashoka fellow Andrés Gallardo is a Mexican who lived in a high crime neighborhood. He created an app, called Haus, that allows people to ___4___ with their neighbors. The app has a panic button that ___5___ everybody in the neighborhood when a crime is happening. It allows neighbors to organize, chat, share crime statistics and work together. To form and lead this community of communities, Gallardo had to possess what Drayton calls "cognitive empathy-based living for the good of all." Cognitive empathy is the ability to perceive how people are feeling in ___6___ circumstances. "For the good of all" is the capacity to build teams. It doesn't matter if you are working in the cafeteria or the inspection line of a plant, companies will now only hire people who can ___7___ problems and organize responses. Millions of people already live with this mindset. But a lot of people still inhabit the world of following rules and repetitive skills. They hear society telling them: "We don't need you. We don't need your kids, either." Of course, those people go into reactionary mode and strike back. The central ___8___ of our time, Drayton says, is to make everyone a changemaker. In an earlier era, he says, society realized it needed universal ___9___. Today, schools have to develop the curriculums and assessments to make the changemaking mentality universal. They have to understand this is their criteria for success. Ashoka has studied social movements to find out how this kind of ___10___ shift can be promoted. It turns out that successful movements take similar steps.
