Palm Beach County, Fla., schools have spent about $500,000 on classroom tools, such as student clicker systems and interactive whiteboards, during a time when the district cannot afford teacher raises. Some question whether the high-tech gadgets are worth it. Many teachers, however, said technology enhances learning. One principal said technology doesn't negate the need for an effective teacher. "You're still seeing a human being explain and interpret," he noted. "The teacher is still front and center."
