Most professors have avoided straying far from their original lesson plans, but they acknowledge that the attacks merit attention.
"These events are so important that we can't ignore them," said Douglas Maclean, a philosophy professor.
In lecturing about the attacks and their aftermath, professors said they often find themselves unable to hide their beliefs about recent events.
Journalism Professor Chuck Stone compared the situation in classrooms to the world of journalism, explaining that he believes objectivity is a myth when dealing with such enormous events.
History Professor Sarah Shields said the significance of recent events warrants class discussion, even if it means her personal opinions are included. Shields teaches two classes -- "The Modern Muslim World" and "The Middle East and the West."
"It would not be appropriate for me to keep that out of the classroom," said Shields, a member of the Progressive Faculty Network.
Lindsay Herrington, a student in Shields' "The Modern Muslim World" class, said Shields has managed to share her opinion and remain fair in her lectures. "I think she's been very good about it," Herrington said.
Parisa Haghshenas, a senior from Tehran, Iran, also said she was impressed with Shields' objectivity.
"She's not been biased at all," Haghshenas said.
