项目摘要

Students with disabilities often have fewer opportunities for experiential learning, an important component of quality STEM education. With continued shifts toward the use of digital media to supplement instruction in STEM classrooms, much of the content remains inaccessible, particular for students with visual impairments. The promise of technology and use of tactile graphics is an effective, emerging innovation for providing more complete access to important information and materials. Tactile graphics are images that use raised surfaces to convey non-textual information such as maps, paintings, graphs and diagrams. Touchscreen-based smart devices allow visual information to be digitally and dynamically represented via tactile, auditory, visual, and kinesthetic feedback. Tactile graphic technology embedded in touchscreen devices can be leveraged to make STEM content more accessible to blind and visually impaired students. This project will develop a learner-centered, perceptually-motivated framework addressing the requirements for students with blindness and visual impairments to access graphical content in STEM. Using TouchSense technology, the investigators will create instructional materials using tactile graphics and test them in a pilot classroom of both sighted and BVI students. The investigators will work with approximately 150 students with visual impairments to understand the kind of feedback that is most appropriate for specific content in algebra (coordinate plane), cell biology, and geography. Qualitative research methods will be used to analyze the video-based data set. This project is supported by NSF's EHR Core Research (ECR) program and the Discovery Research PreK-12 Program. The ECR program emphasizes fundamental STEM education research that generates foundational knowledge in the field. Investments are made in critical areas that are essential, broad and enduring: STEM learning and STEM learning environments, broadening participation in STEM, and STEM workforce development. The program supports the accumulation of robust evidence to inform efforts to understand, build theory to explain, and suggest intervention and innovations to address persistent challenges in STEM interest, education, learning and participation. The Discovery Research PreK-12 program (DRK-12) seeks to significantly enhance the learning and teaching of science, technology, engineering and mathematics (STEM) by preK-12 students and teachers, through research and development of innovative resources, models and tools (RMTs). Projects in the DRK-12 program build on fundamental research in STEM education and prior research and development efforts that provide theoretical and empirical justification for proposed projects.

残疾学生通常有更少的体验学习机会，这是质量STEM教育的重要组成部分。随着持续转变数字媒体来补充STEM教室中的教学，许多内容仍然无法访问，尤其是视觉障碍的学生。技术的承诺和触觉图形的使用是一种有效的，新兴的创新，可提供更完整的重要信息和材料的访问。触觉图形是使用凸起的表面传达非文本信息的图像，例如地图，绘画，图形和图表。基于触摸屏的智能设备允许通过触觉，听觉，视觉和动力学反馈以数字和动态表示视觉信息。可以利用嵌入在触摸屏设备中的触觉图形技术，以使盲目和视力障碍学生更容易获得STEM内容。该项目将开发一个以学习者为中心的，感知动机的框架，以解决失明和视觉障碍的学生的要求，以访问STEM中的图形内容。使用触摸索技术，研究人员将使用触觉图形创建教学材料，并在视力和BVI学生的试点教室中对其进行测试。研究人员将与大约150名视觉障碍的学生合作，以了解最适合代数（坐标平面），细胞生物学和地理的反馈。定性研究方法将用于分析基于视频的数据集。该项目得到了NSF的EHR核心研究（ECR）计划和Discovery Research Prek-12计划的支持。 ECR计划强调了基本的STEM教育研究，该研究在该领域产生了基础知识。投资是在重要，广泛和持久的关键领域进行的：STEM学习和STEM学习环境，扩大参与STEM以及STEM劳动力的发展。该计划支持积累强大的证据，以告知努力，以理解，建立理论来解释并提出干预和创新，以应对STEM兴趣，教育，学习和参与方面的持续挑战。 Discovery Research Prek-12计划（DRK-12）试图通过研究和开发创新资源，模型和工具（RMTS）的研究和开发，从而显着增强PreK-12学生和教师对科学，技术，工程和数学（STEM）的学习和教学。 DRK-12计划中的项目基于STEM教育和先前的研发工作的基础研究，这些研究为拟议项目提供了理论和经验的理由。
