Research shows that reading comprehension improves when students have a strong oral and print vocabulary. By providing students with word-study opportunities, students are encouraged to develop a love of language and an ongoing curiosity about words, their origins, and their multiple meanings and usages. The vocabulary word lists, skills-practice exercises, reviews, and tests provided in these Vocabulary Power Workbooks may be used for systematic vocabulary instruction, enabling students to expand their vocabularies, develop a deeper understanding of language, and improve their reading comprehension. The vocabulary teaching, word lists, and exercise types in Vocabulary Power have been carefully selected on the basis of current research in word study. Sources such as Teaching Reading Vocabulary by Dale D. Johnson and P. David Pearson; Teaching Vocabulary to Improve Reading Comprehension by William E. Nagy; The Living Word, a national vocabulary inventory by Dale Edgar and Joseph O’Rourke; and various articles from the Journal of Reading have been used to help determine the course of instruction and to identify vocabulary words that students should know at each grade level. Therefore, the words selected for study in this workbook are developmentally appropriate and reflect the varied interests and vocabulary of today’s students. Answer keys are included in the Teacher Annotated Editions.
