This study examined the usability of an assessment-for-learning (AfL) system that provides audio-tactile graphics for alegbra content (geometric sequences) for individuals with visual impairments -- two who are blind and two with low vision. It found that the system is generally usable as a mathematics AfL system. [ABSTRACT FROM AUTHOR] |
