Answer:
Providing appropriate non violent role model.
Explanation:
Albert Bandura was a social psychologist who worked on observational learning behavior. He discussed how children's behavior can be influenced by observation. The children who watched the aggressive movie act in an aggressive manner. The learning that occurs through watching and imitating and does not influence my personal experiences are called social learning. Thus if children watch or imitate non-violent behavior or action they behave in a non-destructing way.
Thus modeling and imitation are the way through which children can learn a behavior whether it is violent or non-violent.
