Description

<p>The purpose of this study is to clarify the difficulties in solving mathematical calculations with low vision and concentric contraction, at a stage prior to think about difficulties in learning mathematics for low vision students. Twelve sighted university students cooperated in this experiment, and they solved calculations using a low-vision simulation lens. As a result of this experiment, the condition comparing with the lens (low vision) and the sighted, there were significant differences in the “answer completion rate”, “answer time”, and “score”. It has also suggested that students with low vision and concentric contraction have an effect on “answer time” and “score”. Moreover, in the condition of concentric contraction, there were more significant differences due to mistakes in copying and writing, and it was indicated that difficulty in grasping the whole image could affect calculations. Based on the above results, this study could focus on the following four points, the difficulty in learning mathematics with low vision and concentric contraction; “require time”, “copied and written mistakes”, “difficult to grasp the whole image”, and “difficulty in eye movement”.</p>
