Use concrete examples if you have any. The main point is to paint a clear picture for the interviewer about the way you engage with teachers. Walk them through what you might do, step by step, without getting into too much detail.
"I ask the principal if I can take up some time on professional development day for a seminar to teach the teachers about a new technology. I gather all the teachers on that day and I'll give them an overview of the technology. For instance, it might be a new eLearning platform. I'll show them a quick tour of the features and give examples of how they might use them in the class. Then I'll have the teachers interact with the platform for 5-10 minutes, and then we'll have a Q&A session. I take their feedback and then I make sure that they have easy access to me if they have any more concerns or questions."
