Exercises are provided in a set of five workbooks designed to aid data processing students in building vocabulary and reading skills. Each workbook borrows from the data processing vocabulary to provide explanations and exercises for a sequential series of learning objectives. One workbook concentrates on developing the ability to determine word meanings through contextual inference. Exercises in this booklet are designed to demonstrate the variety of meanings a word can have in different contexts and to caution students about the limitations of using context clues. Another workbook provides exercises focusing on common suffixes and prefixes which can help the student recognize and define words with which he/she may not be familiar. A third workbook presents exercises which promote efficient dictionary usage, by reinforcing students' understanding of alphabetical order and of the components of a dictionary entry. The fourth workbook illustrates learning strategies that can be used in mastering technical vocabulary encountered in reading assignments, and the fifth booklet presents exercises in inference, which help students recognize antecedents of pronouns, read literally, understand what is implied by an author, and contrast what is implied with what is said. Accompanying the exercises in the workbooks are pre- and post-tests to help students assess their progress in terms of each of the instructional objectives covered. (JP)
