I think reminding students about the expectation before or during lessons is important and may help limit shouting out. Maybe even having a ball to pass out to students when it is their turn to talk may limit the number of shout-outs.

I would watch the way I call on students and ask questions in class. Not too fast in succession, more succinct and orderly. These students just want to show that they’re capable and hard working. A strategy I would implement is having a reward system but ONLY rewarding students if they raise their hand. This way, they learn that shouting out in class does nothing for them.

Always set your expectations before class begins, this will ensure that the students know what you expect from them before class starts. I would also suggest, if they are not following the expectations on purpose, to create some form of punishment. I don't mean punishment in a way that is rude or embarrassing, but I think if students are not following expectations that taking 5 minutes of recess would get them to think twice before ignoring your requests. I would also say that with adding a punishment, it takes time for students to break bad behaviors, so if you see a student correct themselves or apologize, don't use the punishment then, this is for the cases where it is necessary.

This is something that maybe you could create a point system, rewarding them for good behavior. Not just them but the whole class. Give them warnings and possible consequences for if they keep doing it. This could also be a behavioral issue and should be consulted with the other teachers to see if that is something that only they do in your class or if they do it in other classes.

Maybe come up with a creative new way to "raise hands" such as having a "talking ball" where only students who are holding the ball can speak out. This would help eliminate the calling out in class.

Try to not acknowledge a student's answer if they call out. Also, going over classroom rules before starting a lecture can be helpful. Perhaps also use a virtual hand-raise platform, one where students press a keyboard button if they know the answer and the teacher chooses the first name to pop up on the screen to answer.

Track their behavior using points that only you and the student are aware of. The more points the more severe it gets, less recess, up to call home.

I have witnessed teachers that have a system for signals their students can show with their hands that shows "agree" and "disagree". This gets the students in a habit of raising their hands to answer, so when it is time to call on a student to answer orally, their first instinct is to raise their hand instead of calling out.

Warn the students that you will not acknowledge their answers unless they raise their hands. Encourage the students to raise their hands by only calling on those who put their hands up and thanking them for doing so.

I think that maybe coming up with a new method or having a few classes where everyone is silent until called upon may be neccessary.

I would use a point system. If the student were to call out, I would ignore them and call on a student who has their hand raised and reward them. If it continuously happens, especially with the same individual, I would talk to them privately. If it continues, I would send a letter home.

Implement a system of hand signals that students can use to indicate they have something to say. One such gesture is to raise one finger. As a reminder, post a visual indication in the classroom, such as an icon of a raised hand. When students correctly raise their hands, praise them and give them a reward to reinforce the desired behavior. Make expectations and consequences for shouting out while not raising your hands clear. Students should be encouraged to observe their peers who constantly raise their hands. Students that shout out a lot should be reminded of the rule and its significance in a private discussion.

You could also use a talking stick.

If it becomes too much of a distraction in the classroom I would pull them aside after class to remind them that they should raise their hand before speaking. If they keep shouting out after that I suggest writing a note home, maybe the parents can get through to them and tell them that it is disruptive and occasionally rude to shout out.

Instead of simply telling the child to stop, enforce consequences to stop the behavior. If the behavior persists, involve parents or administration.

I would use sentence structures or do more student talk so they are all able to share something with a group of students.

I would ignore the students until the appropriate classroom procedure is used.

Ignore responses that are shouted out. They will get the point when they are not acknowledged. They may be upset at first but if they want to participate then they must behave in the way that has been shown to them by example.
