Maybe a strike to the throat would startle the student exascerbate the stomping action? But then again what would a punch to the head do? I never expected to be seriously considering using blows against a student.

Unless you are a trained martial artist or EXTEMELY strong, you will not be able to kill someone with a blow to the throat from that angle.
But I'd recommend a blow to the side of the neck with your forearm or the side of your fist, this will get their attention and maybe incapacitate them with almost no chance of serious injury. If you hit the front of the throat you might possibly damage the trachea (medical emergency).
Actually the thumbtack idea is the best one I've heard so far.
