In this paper we discuss the role of visual resources, namely Greek Sign Language videos, concept maps and pictures, and their allocation in a multimedia educational software designed to enhance reading comprehension in deaf children. First, we summarize research findings from three bodies of literature that informed the design of the software: reading comprehension and deaf children, the role of visual displays in reading comprehension and multimedia learning theories. In the following part, we describe the software "See and See" and explain how relevant theory and research regarding visual displays and multimedia learning has been applied to its design. Finally, we present a pilot evaluation of "See and See" regarding the students' interaction with the software and its role in reading comprehension.
