Some schools in Arizona have taken a low-tech approach to education, preferring to focus on the fundamentals. Officials, who expect enrollment at the "basics" schools to grow, say students learn in rows and teachers stand at a chalkboard. "It cuts way down on distractions when a classroom is teacher-centered," said Patti Karr, a fourth-grade teacher. "Kids aren't sitting in groups, and they aren't relying on someone else to do their work. They learn to be independent learners."
