At Fossil Ridge High School, every television in the building was tuned to the inauguration so all 2,300 students could see it.
"We have technology that allows us to beam to every classroom, auditorium, cafeteria, everywhere," Principal David Hadley said. "We just thought, 'Why not? It's a great day in American history, and we ought to show it.'"
Students in one classroom cheered loudly when Obama finished taking the oath of office.
"I can say, 'I was in high school, 14 years old, when the first African-American president was elected," freshman Jessica Zeller said.
All Keller students in grades K through 12 watched the inauguration as part of their social studies curriculum.
