The knowledge deficit in action

Occasionally Ill stumble across a passage that seems perfectly straightforward to me, but that I see students get confused about  over and over again. One such passage begins in the following way: Through a friends father, Elizabeth found a job at a publishing company. Her parents were puzzled by this. The daughters of their friends were announcing their engagements in the Times, and those who joined the Peace Corps or had gone to graduate school were filed under the heading of Useful Service as if they had entered convents or dedicated themselves to the poor. The passage continues for another couple of sentences, but thats pretty much the gist of it. That my students should have such difficulty with this of all passages was a mystery I had filed away in a mental drawer somewhere, to be trotted out an examined from time to time but never yielding sufficient clues for me to draw any real conclusions from. Then I had a couple of illuminating moments. First, I had a student miss a Writing question because she did not know what the Peace Corps was. This was a girl who liked to read and had already scored a 750 in CR not the type of kid Id expect to have that sort of gap. Next, a friend of mine who teaches high school told me that her AP students did not understand what a mistress was as in, they had never been exposed to the concept and couldnt really grasp it. She also told me the following anecdotes about her son, who had just finished his freshman year of high school: One, he had accidentally bubbled in, on a practice ACT, that he intended to pursue a two-year college degree because shed recently explained to him that it took her two years to get her masters, and he didnt realize that people go to school for four years of undergraduate education before they go to graduate school. And two, while going over a newspaper article with him, she discovered that he did not know what pesticides were. This despite his having attended an à ¼ber-progressive middle school with a community garden! Incidentally, her son is a very smart boy (albeit not much of a reader), but no one had ever bothered to explain to him these very basic pieces of information that most adults take for granted. Everyone, his mother included, assumed he knew them and therefore never saw any reason to discuss them. His mother was absolutely gobsmacked when she discovered what he didnt know. (If youre a teenager reading this, dont be so quick to laugh. I guarantee that there are some very important pieces of information about life in the real world that you dont know either.) The moral of the story? Every time I think Ive stopped taking things for granted, I discover that I need to strip away yet more of my preconceptions about what pieces of knowledge I can and cannot assume students possess. After all that, I started taking a look at the SAT from another angle: that of cultural reference points that most adults dont give a second thought to but that plenty of kids taking the SAT havent picked up. I was inspired, of course, by E.D. Hirsch, but the reference points arent so much Great Events in Western Civilization as they are things you learn from reading a newspaper on a regular basis. Even a really bad newspaper. Then today I happened to be going over the passage cited at the beginning of the post, and suddenly I had a lightbulb moment. Its  chock-full of references that wouldnt give most adult readers pause, but that the average teenager wouldnt be able to make heads or tails of. 1. Announcing engagements in the Times Assumed knowledge: The Times refers to a newspaper, e.g.  The New York Times. When people get engaged, they sometimes post announcements in the local newspaper. Usually the people who do this are relatively well-off or socially prominent, especially in a newspaper like The New York Times. This piece of information suggests that Elizabeths family is probably at least upper-middle class, if not outright wealthy, which in turn suggests why her parents are surprised that she doesnt want to take money from them. 2. The Peace Corps(!) Assumed knowledge: The Peace Corps is a governmental organization that places American volunteers (usually college graduates) in various high-need areas in the developing world. Members may teach English, help preserve wildlife, or run recycling programs. In general, they have a reputation for being left-leaning tree huggers. 3. Graduate school Assumed knowledge: Graduate school refers to any post-college academic program leading to a masters or doctoral degree. Most masters program last two years, and most doctoral programs 5-7. The doctorate is the highest academic degree one can receive. In order to apply to graduate school, you must first obtain a bachelors degree (four-year undergraduate degree). 4. Convent Assumed knowledge: a convent is a place where nuns live apart from the world in order to devote themselves to prayer. For a good part of European history, unmarried women were expected to enter one. By equating joining a convent with Useful Service, the author is being ironic that is, suggesting that Elizabeths parents would have considered it more useful for Elizabeth to renounce all worldly goods and lock herself away than to take a job at a publishing house. Are you starting to get the picture? Technically, it is not actually necessary to understand all of these references to answer either of the questions that accompanies the passage. But that is somewhat beside the point. The point is that if the reader does not have a pretty darn good idea of what these things refer to, the passage itself has the potential to read like sheer gobbledygook. At that point, its not even relevant whether the questions can be answered without that information because the reader is so thoroughly lost that he or she can barely even focus on the questions. Knowledge deficit indeed.
