科学教学通常高度依赖于通过教科书、教师演示和基于计算机的多媒体材料传达的科学概念的视觉表示。对于有视觉障碍的学生如何获取和解释这些类型的依赖于视觉的教学材料知之甚少。本研究探讨了新型触觉（模拟触觉反馈和动觉）教学技术在向视力障碍中学生教授细胞形态和功能方面的功效。该研究调查了学生之前在课堂教学中学习细胞和细胞功能的经历，以及触觉反馈技术如何影响学生对动物细胞的 3D 性质、细胞器的形态和功能的认识，以及学生对触觉技术作为教学工具的兴趣。二十一名有视力障碍的学生参加了这项研究。学生们使用触觉点探针探索了细胞的触觉模型，使他们能够感觉到细胞及其细胞器。结果表明，学生们识别细胞器的能力得到了显着提高，并发现该技术作为一种教学工具非常有趣。讨论了针对有视力障碍的学生对额外自适应技术的需求。
Science instruction is typically highly dependent on visual representations of scientific concepts that are communicated through textbooks, teacher presentations, and computer-based multimedia materials. Little is known about how students with visual impairments access and interpret these types of visually-dependent instructional materials. This study explored the efficacy of new haptic (simulated tactile feedback and kinesthetics) instructional technology for teaching cell morphology and function to middle and high school students with visual impairments. The study examined students’ prior experiences learning about the cell and cell functions in classroom instruction, as well as how haptic feedback technology impacted students’ awareness of the 3-D nature of an animal cell, the morphology and function of cell organelles, and students’ interest in the haptic technology as an instructional tool. Twenty-one students with visual impairment participated in the study. Students explored a tactile model of the cell with a haptic point probe that allowed them to feel the cell and its organelles. Results showed that students made significant gains in their ability to identify cell organelles and found the technology to be highly interesting as an instructional tool. The need for additional adaptive technology for students with visual impairments is discussed.
