I disagree.
There are plenty of times that a TV show is a valid teaching tool.
There are SOME times, but most of the time it’s just a crutch for poor teachers. Off the top of my head one time I can think of the TV being actually useful was in American Government, the teacher found a PBS series of round table discussions on various Constitutional points. The show was useful because it presented about a dozen views on each episode, also the teacher didn’t do the typical turn off lights-turn on TV, go sit down; it took us two or three class sessions to get through each 1 hour episode because he would pause it to add his own point and open up class room discussion. In that style the TV can be useful, but that’s so rarely the method used, most of the time it’s turn on the TV and turn off the teacher.
