The knowledge deficit in action

Occasionally I’ll 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 friend’s 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 that’s 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 I’d 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 couldn’t 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 she’d recently explained to him that it took her two years to get her master’s, and he didn’t 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 über-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 didn’t know. (If you’re a teenager reading this, don’t be so quick to laugh. I guarantee that there are some very important pieces of information about life in the real world that you don’t know either.)

The moral of the story? Every time I think I’ve 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 don’t give a second thought to but that plenty of kids taking the SAT haven’t picked up. I was inspired, of course, by E.D. Hirsch, but the reference points aren’t 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. It’s chock-full of references that wouldn’t give most adult readers pause, but that the average teenager wouldn’t 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 Elizabeth’s family is probably at least upper-middle class, if not outright wealthy, which in turn suggests why her parents are surprised that she doesn’t 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 Elizabeth’s 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, it’s 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.

Hard questions, easy answers (or: when you hear hoofbeats, think horses, not zebras)

Perhaps you’ve heard the saying “when you hear hoofbeats, think horses, not zebras.” If you’re not familiar with the expression, it means that when searching for an explanation, you should always consider obvious possibilities before thinking about more unlikely options. Whenever I tutor the Writing section of the SAT, I find myself uttering these words with inordinate frequency.

I’ve worked with a number of students trying to pull their Writing scores from the mid-600s to the 750+ range. Most have done well on practice tests but then unexpectedly seen their scores drop on the actual test. Unsurprisingly, they were puzzled by their performance on the real thing; they just couldn’t figure out what they had done differently. And at first glance, they did seem to know what they were doing. When I worked very carefully through a section with them, however, some cracks inevitably emerged. Not a lot, mind you, but just enough to consistently pull them down. They would be sailing along, identifying errors like there was no tomorrow, when all of the sudden they would hit a question whose error (if any) they simply could not identify.

When that happened, they would stop and read the sentence again. And when they couldn’t hear anything wrong, they would read the sentence again, slowly, trying to hear whether something was wrong (mistake #1). Then, if they really didn’t want to choose “No error” but weren’t sure whether something was truly wrong, they would start searching for an explanation, usually a somewhat convoluted one, for why a perfectly acceptable construction was ambiguous or awkward or otherwise wrong (mistake #2). Almost always they did so when the actual answers — answers based on concepts they understood perfectly well — were staring them right in the face.

One of things that it’s easy to forget — or, in the case of many natural high-scorers who haven’t needed to study the framework of the test, to never realize — is that “hard” questions are not necessarily hard because they test hard concepts. Most often, they are hard either because they test (relatively) simple concepts in hard ways or because they combine concepts in unexpected ways.

Hard questions can — and often do — have “easy” answers. That does not mean that the answer is the option that sounds weird (that’s the distractor answer). It does, however, mean that the answer is likely to be an extremely simple word like “is” or “are” or “it.” It also means that the answer probably involves an extremely common error, like subject verb agreement or pronoun agreement, not some obscure rule you’ve never heard of.

The challenge is figuring out which concept is being tested, not understanding the concept itself. So when people who can usually hear the error come across a question whose answer they don’t instantly hear, their instinctive reaction is to look for something outlandish to be wrong with it, not to think systematically about what the most common errors are and check to see whether the question contains them. In others words, they hear hoofbeats and imagine that a herd of zebras is about to come racing around the corner.

For example, consider the following question, which a very high-scoring student of mine recently missed:

 

(A) Thanks to the strength (B) of the bonds between (C) its

constituent carbon atoms, a diamond has exceptional

physical properties (D) that makes it useful in a wide

variety of industrial applications. (E) No error

 

If you spotted the error immediately, great, but bear with me for illustrative purposes. The sentence itself is rather challenging: it discusses a topic (chemistry) that many students are unlikely to have unpleasant associations with, and it also contains the word “constituent,” which many weaker readers will have difficulty decoding, and whose meaning many slightly stronger readers will not know or be able to figure out. So right there we have two big stumbling blocks likely to distract from the grammar of the sentence. Many test-takers are also likely to think that “Thanks to” sounds too casual and would be considered wrong on a serious test like the SAT. Many other test-takers are likely to just not hear any error.

In that case, the most effective approach is to consider the structure of the test. The most common error is subject-verb agreement, and when in doubt, it’s the error you should always check first. There is exactly one underlined verb in the sentence: “makes.” It singular (remember: singular verbs ends in “-s”), which means that it’s subject must be singular as well.

But what is the subject? “Physical properties,” which is plural, so there’s a disagreement. The answer is therefore (D). The sentence should read “…physical properties that make it useful.”

The moral of the story is that if you don’t spot an error immediately, whatever you do, don’t fall into the loop of endlessly rereading the sentence and trying to figure out whether something sounds funny. Instead, check systematically for the top five or so errors: subject-verb agreement, pronoun agreement (check “it” and “they”), verb tense (pay attention to dates and “time” words), adjectives vs. adverbs (easy to overlook), and, if you’re at the end of a section, faulty comparisons.

If all of those things check out, the sentence is probably fine.
