Abstract:
Many students enter high school unskilled in the art of reading to learn from science textbooks. Even students who can read full-length novels often find science books difficult to read because students have relatively little practice with the various types of expository text structures used by such textbooks (Armbruster, 1991). Expository text structures include generalization, cause and effect, classification, sequence, compare and contrast, and enumeration. An author using the generalization structure, for example, states a generalized main idea statement and then proceeds to defend the argument with facts, reasons, or examples--the so-called supporting details. With the compare and contrast structure, an author relates the similarities and differences between two subjects. In an enumeration paragraph, a simple listing of elements is presented. In this article the authors present an activity using a modified form of the sentence completion or "fill-in-the-blanks" worksheet that reinforces students' fluency with expository structures.
