盲人学生需要获得学习材料。这项研究着眼于盲人使用基于课程的教科书学习科学的情况，并将其与使用集成了复杂性聆听 (L2C)（一种在 NetLogo 上创建的基于代理的模型）的相同课程的学习进行比较。 L2C 系统采用声音反馈，同步提供听觉流。本研究考察了化学中气体动力学分子理论 (KMT) 和气体定律的科学概念知识和系统推理的获取。二十名盲人参与了这项研究；他们被分为两个实验组：使用基于课程的教科书的实验组和使用与基于 L2C 代理的模型集成的相同课程的实验组。结果表明，所有研究参与者都获得了科学知识；两个实验研究组在测试前和测试后都发现了统计学上的显着差异。通过 L2C 模型学习的人在后测中表现出更高的准确率；此外，使用 NetLogo L2C 模型进行学习预测了他们在后测中的成功。两个实验组之间学习任务准确性的比较表明，使用 NetLogo L2C 模型进行学习的参与者在使用集成 L2C 模型的五种学习活动中表现出统计学上的显着差异，但在没有集成 L2C 模型的学习活动中没有发现差异。这些研究结果可能会对将可听化模型作为补偿性辅助手段融入科学教育产生有益的影响，为盲人学生提供实践学习体验。整合可听化模型将支持它们在平等的基础上纳入 K-12 学术课程。
Students who are blind need access to learning materials. This study looks at the learning of science by people who are blind using a curriculum-based textbook compared to their learning using an identical curriculum integrated with the Listening-to-Complexity (L2C), an agent-based model created on NetLogo. The L2C system employs sonified feedback that provides auditory streams synchronically. This study examines acquisition of scientific conceptual knowledge and systems reasoning for the Kinetic Molecular Theory (KMT) of gas and Gas Laws in chemistry. Twenty persons who are blind participated in this research; they were divided into two experimental groups: those using an accessible curriculum-based textbook and those using the same curriculum integrated with L2C agent-based models. Results showed that all research participants gained scientific knowledge; statistically significant differences were found for both experimental research groups between pre- and posttest. Those who learned through the L2C models performed with higher accuracy in the posttest; furthermore, learning using the NetLogo L2C models predicted their success at the posttest. A comparison of learning task accuracy between the two experimental groups showed that the participants who studied using the NetLogo L2C models performed with statistically significant differences in the five learning activities with integrated L2C models, but no differences were found for the learning activities without integrated L2C models. These research results are likely to have a beneficial impact on integrating sonified models in science education as a compensatory aid, allowing hands-on learning experience for students who are blind. Integrating sonified models will support their inclusion in the K-12 academic curriculum on an equal basis.
