This paper discusses research findings regarding vocabulary instruction and reading comprehension and suggests methods to develop vocabulary using visual aids. As indicated by the research, vocabulary instruction is necessary and can lead to improved comprehension; there also appears to be a strong need to relate concrete visual experiences to vocabulary development, providing active, meaningful, and repeated word use. Visual methods for developing vocabulary that involve students actively taking part in their reading vocabulary development include using: interactive video; student illustration of vocabulary; computer software packages designed to develop reading skills; activities that involve visual perception; and graphic organizers, including story maps, collaborative rehearsal of new vocabulary, and student-made flash cards. The use of visuals, combined with cooperative learning groups, provides an effective environment for the development of vocabulary and reading comprehension. (Contains 14 references.) (AEF)
