交互式模拟在科学教育中越来越重要,但大多数对盲人学习者来说是无法使用的。在开发一个PhET交互式科学模拟的无障碍原型时,我们在提供屏幕阅读器访问方面遇到了重大挑战,包括需要:1)描述不可预测的事件序列,2)提示有效的交互,以及3)同时传达多种变化。为了应对这些挑战,我们扩展了对视觉交互内容进行文字描述的现有做法,并为开发无障碍交互式科学模拟的丰富描述创建了新的策略。
Interactive simulations are increasingly important in science education, yet most are inaccessible to blind learners. In developing an accessible prototype of a PhET interactive science simulation, we encountered significant challenges in providing screen reader access, including the need to: 1) describe unpredictable event sequences, 2) cue productive interactions, and 3) to simultaneously convey multiple changes. To address these challenges, we extended existing practices for verbal description of visual interactive content, and we created new strategies for developing rich description for accessible interactive science simulations.
