MULTIMEDIA PHYSICAL SCIENCE PROGRAM FOR HEARING IMPAIRED

聋哑生和重听障学生通常表现出较低的学习成绩，尤其是在科学方面。一个主要原因是为既能听又能读的学生设计的科学材料的普遍使用。此外，由于教师没有接受过关于这一群体的交流需求的培训，教学交付往往很差。这个项目将结合美国手语叙事片段大小的经验研究、基于研究的课程设计实践和计算机技术来开发一个有效的计划来向聋哑人和重听学生教授核心物理内容。这个项目通过有效地向依赖ASL的学生展示材料、组织物理内容以促进掌握和更高层次的思维，以及有效地克服当前听力障碍产品中常见的技术问题来解决听力障碍教学的关键问题。在第一阶段，将制作六节原型课、一个实验室和两个活动，并对不同年龄和英语/ASL能力的初中生进行评估。原型将是一个独立的交钥匙系统，包括计算机、显示器、键盘和耳机。在第二阶段，将制定一个完整的65课核心概念物理科学计划，并在随机对照试验中测试其有效性。拟议的商业应用：该项目将导致为聋哑生和重听学生开发初中和高中核心概念物理科学计划的第二阶段。该计划将包括内容动画，文本和ASL解说，词汇工作，实验室和活动。该产品将对服务于聋哑人和重听学生的学校具有吸引力。此外，它还将有效地用于聋哑人和听障教师培训机构。

Deaf and hard-of-hearing students typically exhibit low academic performance, particularly in science. A primary cause is common usage of science materials designed for students who can both hear and read. Furthermore, instructional delivery is often poor because teachers are untrained in the communication needs of this population. This project will incorporate an empirical study of ASL narrative segment size with research- based curriculum design practices and computer technology to develop an efficacious program to teach core physical science content to deaf and hard- of-hearing students. This project addresses the critical issues of hearing- impaired instruction by effectively presenting material to students who rely on ASL; organizing physical content to facilitate mastery and higher order thinking; and efficiently overcoming technological problems common rn current hearing-impaired products. In Phase I, six prototype lessons, one lab, and two activities will be produced and evaluated with middle and high school students with a range of ages and English/ASL abilities. The prototype will be a stand-alone, turn-key system including computer, monitor, keyboard, and headphones. In Phase II, a complete 65-lesson core concept physical science program will be developed and its efficacy tested in a randomized control trial. PROPOSED COMMERCIAL APPLICATIONS: This project will lead to the Phase II development of a middle school and high school core concepts physical science program for deaf and hard-of-hearing students. The program will include content animations, text and ASL narrations, vocabulary work, labs, and activities. The product will be attractive to schools who serve deaf and hard-of-hearing students. Additionally, it will be effective for training institutions for teachers of the deaf and hearing-impaired.
