If you're looking for stuttering advice for teachers, I congratulate you. It's very noble of you to be that interested in your student's well being, and I'm sure that he or she really appreciates it.
Here are some things you can do to ensure that the stutterer in your classroom gets the most out of your class:
Don't tell your student to “slow down" or “relax" - that just makes it worse.
Don't finish words for the child, or talk on his or her behalf. At best, speak in an unhurried way, and pause frequently. Give a few seconds after the child finishes speaking before you start to speak. By you having slower speech, it'll be much more effective than criticizing or the dreaded “slow down" or “relax".
Have all of the kids in your classroom take turns listening and talking. All of the children, not just the children who stutter (but especially them), find it a lot easier to talk when there aren't many interruptions and they know they have your full attention.
Know that stuttering has zero impact on intelligence. Don't expect any less from your stuttering students than the others, it's only a detriment to them.
Make sure your student knows that you're listening to what he's saying - not how it's delivered. Use your facial expressions and your body language to convey that the content is the only thing you're concerned about.
Feel free to ask your student if there are any needed accommodations. Obviously you'll want to respect their needs, but you also want to make sure that you're not enabling him or her.
Don't make stuttering anything to be upset about, and make it seem just like any other matter.
If possible, reduce the questions that you ask your student, and instead, simply comment on what they have just said.
Above all, make sure that your student knows he or she is accepted as she is, and that you value him or her. Don't make them seem as if they have any kind of disability, or anything comparable - because they don't.
Again, congratulations on looking this up, and best of luck in the classroom.
