Home environment – Children learn what they live. If home is a frightening, violent, abusive, neglectful environment, that’s what the child learns to expect.
Depression, stress and anxiety, feeling powerless – All these factors can cause a student to act out in frustration.
Weapons – The easy availability to weapons of all kinds makes it simple for students to get their hands on them.
Media – Some believe that children exposed to violence through movies, television, video games, the Internet, etc. are desensitized to violence, and therefore commit it and accept it more easily.
Peers – Children are influenced by those around them; not just at home, but in school, and in the community as well. They can learn and accept violent behavior as the norm from their friends.
Learning difficulties/health problems – Learning problems, which can be the result of health issues, can lead to frustration and lashing out.
Lack of guidance – Without adult supervision and positive role models, students don’t learn to distinguish right from wrong – acceptable from unsuitable behavior. They can also struggle without the ability to resolve conflict peacefully.
Attention seeking – Violence can be the result of wanting others to pay attention to the student. Even negative attention.
