Answer: D - Ms. Glenn could intervene in this situation by modeling one or two techniques that can be used to resolve such a disagreement. Modeling is an excellent way for young children to see how adults resolve their conflicts so that they can mimic their methods. Children will argue, and setting up rules that prohibit it creates an environment that could inhibit the timely development of necessary social skills. Punishing Sarah would likely increase her anger toward Ann, which could result in strengthening the conflict. Calling the girls’ parents may be a good idea, but it does not teach the girls the necessary social skills to avoid and resolve conflicts in the future.
