A student's reading comprehension and vocabulary help to increase her or his ability to write effectively. A technique I use in my classes, in addition to having students complete the worksheets, is to have them copy the reading before completing the worksheet. It seems that many students in my classes have lost (or never really mastered) the mechanical ability and endurance necessary to write an in-class essay. Try the exercise. Have students copy a passage from, say Adam Smith, and ask the student to read what he or she wrote. Both you and the student may be surprised.
