Gerunds are words ending in "ing". It is believed that using gerunds can help reinforce the positive behavior another would like to see rather than attacking a bad behavior. For example, a teacher might see students running down the hall and calmly say "walking" rather than yell "stop running" in an agitated voice. He might say "gently" (an adverb) instead of insisting "calm down!"
