【 摘 要 】

This study was an initial effort to designand develop an accessible simulation-based science assessment task, involvingevaporation of water, and to examine its usability via a largely qualitative casestudy of the experiences of three grade 8-9 students at a residential schoolfor students who are blind. The task had three simulations of water particlesin various stages of evaporation. Students used the science task in fourconditions: (a) screen reader and supplementary non-speech audio, (b) game-controller-basedhaptics, (c) tablet-based vibrotactile haptics, and (d) tactile graphics. Wefound that students were able to use the task in all conditions with somesuccess, though they experienced a range of usability issues. These issues couldbe addressed through improvements in one or more of (a) student familiaritywith the access technologies, (b) design of the task content, and (c) the accesstechnologies themselves and their applications in assessment settings.
