It has been said that television is a vast wasteland. Here are some exercises in reality for schoolchildren so that they can judge the value of television for themselves.
Adults can benefit too.
Show the class a typical TV program. The example that I will use shows the so-called hero swinging on a rope from a rooftop onto a very large balcony on another building. The guys on the balcony are, of course, all bad. Our hero has a machine gun slung over his shoulder. Upon landing on the balcony, surprising the bad guys, he un-slings his machine gun and proceeds to shoot down all the bad guys dead.
