Okay, so there are a lot of replies in this thread that aren't really based in current research in the fields of education, psychology, or special education. I don't want to call anyone out in specific, and it's not really possible to diagnose what's going on in this classroom, with this kid online. Likewise, a blurb in a forum isn't really enough to solve all your problems. However, I can give you a push in the right direction so you can find more information on your own.
There is a lot of research about effective/ ineffective praise. A lot of the websites with praise language post ineffective language/ conditions. Carol Dweck is a good person to start with on the subject, but there are other sources you will find/ should consider after reading some of her work.
Look up ways to systematically increase the student's frustration tolerance and ability to delay gratification. Those are the terms you should use in your search. Those concepts are a more sophisticated approach than was found in the old intrinsic/ extrinsic motivation debate.
Adults, kids, rats, and bacteria are sensitive to reinforcement systems. The people who argued against reinforcement systems did so in books that they got paid to sell and in professorships where they were paid to work. In cases where people think they don't work, the people involved are implementing them wrong, don't understand the process, and/ or aren't collecting/ looking at the data right.
Reinforcement systems are more than just providing candy. In many cases where teachers are seeing behavior problems, there may be multiple reinforcement systems that reinforce competing behaviors. For example, they may offer a candy to people who raise their hand consistently, but acknowledge the calling out of answers. In the case where kids call out in that sytem, attention> candy, but the teacher may be completely confused about why the kids are calling out.
Consistency and format in providing directions and in providing reinforcement is key. In the teachers I've trained, these are usually the biggest issues for improving students behavior. When students are misbehaving, I can always find issues in these areas and help improve practice that produces measureable changes in students' behaviors. It's hard to see on your own, but you could role play from the kids' perspectives. In the order that you are saying/ doing things, could you complete the intended directions? Or put another way, how well do the intended/ actual directions match up? What are all the ways kids are getting reinforced? Are there kids who are not getting reinforced? Are kids getting reinforced for misbehaving?
Look up the words antecedent- behavior- consequence, and see what you can figure out about each specific behavior. Don't lump 3 behaviors together. Also, only think of consequences as what happens immediately after the behavior. If a student acts up and immediately gets put out in the hallway, the student is acting up in order to get put out in the hallway. In that case, the rules around putting the kid out in the hallway is encouraging the student to misbehave.
If this is an issue, somebody should hire me to train up teachers on classroom management/ discipline. I've done it in the States with classes full of students who are violent (e.g. arsonists, rapists) and have histories of abuse. I'm looking for my ticket to Taiwan, and training people/ solving problems in classes with kids like this is something I've done a lot of over the years.
Anyway, I hope this post helps some.
