The massacre at Sandy Hook Elementary was part of a discussion at Fresno State today.
Teachers joined for a workshop on bullying.
They learned how to encourage students to treat one another with kindness and to recognize signs of bullying in a student's writing.
Organizers say that the seeds for disturbing acts like the Connecticut shooting may be planted in childhood.
"Teachers are often called upon to lead their students through these tragic situations, so I think teachers need this kind of support," Kathleen Godfrey said.
This was the second of three workshops for teachers.
