Kim Krawczyk was teaching a math lesson for her freshman students on a Wednesday in 2018 when shots rang out in the building. The attack on Marjory Stoneman Douglas High School in Parkland, Fla., would leave 14 students and three staff members dead.
While no shots were fired into her classroom that day, she and her students were traumatized, and she says school shootings like the one last week in Uvalde, Texas, resurface the experience for them.
