Using todays technology, it is possible for the teacher to remotely interact with students via remote control, either  as an entire class, an individual or a predefined group. But thats not all, realtime application and internet monitoring allows total control over the class, and inappropriate applications or websites can be closed or blocked in a matter of seconds from the teachers computer.  Of course the ability to  exhibit their own screen or another pupils to the rest of the class comes as standard, and does the option to blank the classes screens to ensure their full attention.
