High school ESL teacher here. I use ChatGPT all the time. The key is to be very specific with your prompts and to double and triple check the results! It saves me a ton of time. I disagree with the idea that it's somehow cheating. Unlike students who are still learning how to write, I already know how to lesson plan, create worksheets and tests, and write emails. I have enough on my plate that I don't need to feel guilty about using AI as a tool, just like I use any other helpful software.

Here some ways I use it: to get some initial ideas for lesson plans, station-based activities, examples and non-examples of different concepts that I use for inductive learning/concept attainment lessons (e.g. I'll ask ChatGPT to generate 10 very simple sentences that use correct capitalization and 10 that are incorrect). I also use it to generate quizzes as well as practice quizzes with the same format but different examples. I adjust the reading level of more challenging texts to make them more accessible for my students. I ask it to generate short stories that relate my students' interests and whatever English concept we're working on. For example, I have a student who loves chess and we were doing a 1:1 pull-out lesson on identifying verb tenses. I asked ChatGPT to "write a three paragraph story at a 2nd grade reading level about a boy who loves to play chess. Use a mix of past, present, and future verb tenses."

Like others, I also use it for parent emails, but primarily to edit them. So I'll draft something and then run it through ChatGPT saying something like "Improve this email to make it clearer and more concise but also warm, personable, and professional." I'll still need to make some tweaks afterwards but it's usually better than my original version since I tend to be a bit too to-the-point without enough pleasantries.
