This individualized inservice packet on vocabulary development in the content areas aims to enable teachers to equip students with varied word recognition skills. It is one of a nine-part series of booklets--Teaching Teen Reading--in self-instructional format intended as a practical resource for teachers desiring condensed, readily usable answers to questions regarding reading instruction. The booklet's four main sections deal with the following areas: (1) context clues; (2) structure (compound words, prefixes and suffixes, roots and affixes, and basic principles of syllabication); (3) sound (basic phonic principles); and (4) dictionary skills. A self-corrective post test, a glossary, and a 21-item bibliography are attached. (SR)
