Anyone who gives in-class tests will now need to monitor student's wrists to see if they are wearing one of these cunningly designed cheating devices. They even have "panic buttons" that can be pressed to reveal a regular watch face that shows the time.
The deeper significance of this whole scheme is the way the popular culture now views education primarily as achievement, success and failure.

The ability to succeed on tests is more a function of the ability to memorize or retain specific information than it is about meaningful learning.
