Exploring Auditory Graphing Software in the Classroom

Abstract

Students who are visually impaired make up a population with unique needs for learning. Some tools have been developed to support these needs in the classroom. One such tool, the Graph and Number line Input and Exploration software (GNIE), was developed by the Georgia Institute of Technology Sonification Lab. GNIE was deployed for use in a middle school math classroom at the Georgia Academy for the Blind (GAB) for 2 years starting in fall 2012. We interviewed the middle school math teacher throughout the deployment to learn about the challenges faced when teaching: lesson planning, execution, and review. We also observed how these changed when using GNIE compared to traditional teaching materials. During these 2 years, we conducted interviews and focus groups with students to learn about their attitudes toward tactile graphs compared to auditory graphs. With these in mind, we present lessons learned from the use of GNIE in a real-world classroom and implications for design of software to aid graphical learning for students with vision impairments.
