Expanded captions are designed to enhance the educational value by linking unfamiliar words to one of three types of information: vocabulary definitions, labeled illustrations, or concept maps. This study investigated the effects of expanded captions versus standard captions on the comprehension of educational video materials on DVD by secondary students who are deaf or hard of hearing. Participants were assigned randomly to two groups, with each group experiencing both conditions in counterbalanced order.
