Multitasking: Nonproductive Yet Lingering Myth
Solving two problems with one action is hitting two birds with one stone. This is certainly productive but this is different from performing two acts at the same time. "No man could serve two masters" is a favorite verse from the Scriptures. No one would be happy to see his or her surgeon texting while performing a surgery. No one should be texting while driving. Yet, we see plenty of examples out there. The following diagram shows why texting and driving severely lengthens the reaction time of a driver:
Texting is in fact worse than being intoxicated. The unexplainable part is that people already know this. The following is a graph from a recent paper in the Journal of Experimental Psychology: Applied:
When I look at a classroom and I see a teacher who is so worried about what is going at home, I can imagine what this actually does to learning inside a classroom. If a society is unable to support a teacher's need to support his or her family, what kind of performance are we to expect inside a classroom. When a teacher does other activities totally separate from teaching in order to augment one's income to support a family, should we really expect 100 percent? It does not make sense to expect teachers to be capable of multitasking when no one really is. I guess the answer is simple - We do not really care.
