Yes, I wrote about it in my other comment (copy-pasted below). Like I said, I think it's a valid assignment, but the way in which OP's professor frames its purpose is an important distinction "I had to do this for my SLP course in fluency. The intended purpose as it was explained to us was that we ask our clients to practice intentional stuttering in therapy and it makes us more credible as therapists if it's a technique we've tried ourselves. It's not supposed to give insight into what it's like to have a legitimate stutter, it's supposed to give insight into what it's like to stutter on purpose, which is an evidence-based therapy technique."
