Thanks for your kind answers. In grounded theory, Can I present imaginary scenarios (what I meant by case in my previous question) as stimulus for their responses and get their answers accordingly, instead of asking the views of the participants explicitly?

Thanks for your answer. I don't want use vignettes at all my questions. But at first I want to start with vignette because of knowing what they think about willpower. This is my first question: A school administration wanted to know the characteristics of the teachers. And they asked to the students characters of teachers. For a teacher, students said that he has a strong willpower. What do you think this teacher has? Or how this teacher reacted?

Thank you very much for your answer.

Kind regards.

Yes, grounded theory is a great one. Go for it.
