The report describes the development and evaluation of an instructional program in tangible graph interpretation for braille readers. Because graphs frequently appear in textbooks and in other printed sources, lack of appropriate translation for blind persons can be a significant educational obstacle. Based on anlyses of typical graph reading tasks, skills and concepts fundamental to the graph reading process were identified and then incorporated into a logically sequenced instructional program. A high priority was given to the application of relevant research findings in the areas of display design and skills training. The effectiveness of the program was assessed using 60 braille readers in grades 5-10. The results indicated that substantial gains in graph literacy could be realized with the program in a relatively short time. (Author/CL)
