poor classroom management often speak in a very high voice

speak from the chest. It gives you power, it’s believable, and it’s not straining. My acting coaches would say, “think low.”

high pitched, it can sometimes sound desperate, apologetic, and it seems as if you are asking students for permission when you are giving directions.

try wording the question a little more provocatively, like: “How does your solution to the scenario differ from the recommended solution provided in the training?”

If you’re primarily an introvert, you’re less outwardly expressive and more likely to process your emotions and thoughts internally. You tend to embrace critical-thinking and you do more listening than talking – but your introspective ways may leave you feeling awkward in social or group settings
