If this can help you ... From my own experience, I advise you that you should also ban music, external noises and any other distractions ... Basically to make your students bored and that the only thing that "entertains" them is to code in the computer.
By the way, I would be interested to know more about your project and its progress, if you could give me some form of contact I would greatly appreciate it.
