Student teachers feeling the toll of school violence, educator says

Deena Gumina was in third grade in 1999 when a mass shooting at Columbine High School devastated her hometown of Littleton, Colorado. In the years since, these kinds of violent events have become increasingly common across the country, altering the face of K-12 education in the United States—including for Gumina herself. She graduated from high school at Columbine in 2008 and later taught elementary school for five years in Denver.
