Evaluating a tactile approach to programming scratch

Abstract

Computer Science in K-12 is continuing to become more prevalent. Because learning syntax and debugging can be burdensome, many teachers in K-12 use block languages to teach their students. Block languages, such as Scratch, allow students to focus on simple programming concepts and logic, and therefore, make computer programming easier and more approachable to students. However, block languages are not accessible to students with visual impairments because of block-environments’ high dependence on visual aspects. This paper describes an innovative peripheral device that can help students with visual impairments access Scratch by simply remembering six buttons and guided by auditory cues generated by the computer. In order to test CodeBox64’s usability and efficiency, a simple user study was conducted. Based on the data collected from the user study, CodeBox64 functioned properly and efficiently.
