Field trips to museums, historic sites and other traditional landmarks are occurring virtually these days, as schools rely more on online broadcasts and interactive programs because of budgets cuts and tight testing schedules. While in-person trips would be ideal, Nina Corley, a high-school history teacher in Galveston, Texas, says the electronic versions are great opportunities for students to interact with experts on location in such places as Colonial Williamsburg, Va. "They [students] are able to watch what's going on, ask follow-up questions and play games all in one sitting. It really gets them involved," Corley said.
