The author, a teacher of political science, teaches classes on political violence, terrorism, international relations, and on global security and diplomacy. The author identifies as a Cold War kid, but current students have a very different frame of reference. These students are now the post-9/11 generation--often too young to remember the actual event, though old enough to enlist in the ongoing war that was a response to that attack. What these students know, what they do remember, and what shapes their perspective, are hate crimes, terrorist attacks and mass shootings. These students didn't just duck and cover under their K-12 school desks. They learned to tie tourniquets, and have been taught how to block doors, how to stay silent in a coat closet. These students look for all of the exits at a public event, they are cautious at stores and movie theaters. They carry their phones at all times, not because they are checking their social media, but because they want to be able to reach their parents at any moment. While they do not remember the 9/11 attacks, today's college students do remember others. These students are members of the active-shooter generation, and that means that as a teacher, the author must be prepared to address topics that they have personal experience with as they may arise in the curriculum.
