After reading aloud from an essay about the fast-food industry, I threw a typical softball question to the students of a UC Berkeley composition class:
"What's the argument of the paragraph?"
Silence.
Written by a former student, the paragraph implied that a rise in American obesity is linked to increased dollars spent on fast food.
I called on a student. "Advertising?" she said, a word that appeared in the paragraph only once. Why did this student, a hard-working athlete, so badly misread the paragraph? Because instead of really interpreting the passage, she used a little clue. "Advertising" had been mentioned in the thesis just a paragraph earlier.
Unfortunately, strategies such as hers aren't uncommon in the college classroom. Within the same lesson, another student made quick assumptions about a sentence's meaning because of its first words. My colleagues and I often swap stories like these, in which our students use faulty shorthand in place of critical thinking.
