Abstract

<p>本研究は、弱視生徒が数学の計算問題を解く際の困難を考える前段階として、低視力状態及び視野狭窄状態で計算する際の困難を明らかにすることを目的とした。晴眼の大学生12名を対象に、弱視シミュレーションレンズを用いて計算問題を実施した。実験の結果、レンズ装着状態においては晴眼状態と比較して、解答完了率や解答時間、得点に関して有意差が見られ、低視力状態及び視野狭窄状態では、解答時間や成績に影響があることが示唆された。また、視野狭窄状態では写し間違いや書き間違いが有意に多く見られ、全体把握の困難が計算に影響することが考えられた。以上により、弱視生徒に対する計算学習の指導における観点として、「時間がかかる」、「写し間違い・書き間違い」、「全体把握の難しさ」、「視線の移動の難しさ」の4点が考えられた。</p>

<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>
