I put this infographic together to help many instructors that are struggling with this issue as they teach and are trying to keep students from using AI when they are not supposed to. Be sure to take every opportunity to help students learn about AI Literacy when you can, even when telling them that for this assignment/eval they won’t be able to use it.
You as the instructor are the subject matter expert and must be the one deciding how AI will be used in your classroom and for your assignments/evaluations. For some assignments, the use of AI may not be the right answer in that you are trying to help them develop skills mastery, so they can properly gain the skill of what “right” looks like. Be sure to fully explain that to them so that they have full relevancy and understanding as to why they can or can not use AI.
