The prefaces of textbooks have considerable value as aids in helping students profit more from their reading. But they are frequently ignored by most young readers and rarely if ever assigned by teachers in a formal manner as aids to instruction. A model teaching unit originally using a social studies text can lead students to see the value of a preface, but more importantly, to conclude that the preface of every text has value. In, this model, items requiring responses are typed in a worksheet format, photocopied, and then distributed to the students. Students write their answers on scrap paper, edit them, and then write their final answers in the spaces provided on the worksheet. The model is adaptable to a wide variety of circumstances. It is advisable to have a preface unit on file and readily available for each text that will be used extensively. Students will routinely find themselves reading the preface of a text even when they are not required to do so. (The introduction of the textbook on which the model is based and a sample of questions are included.) (HTH)
