MULTIMEDIA PHYSICAL SCIENCE PROGRAM FOR HEARING IMPAIRED

聋哑和听力障碍的学生通常表现出较低的学习成绩，特别是在科学方面。一个主要原因是普遍使用为既能听又能读的学生设计的科学材料。此外，教学效果往往很差，因为教师没有接受过这一群体沟通需求方面的培训。本计画将结合美国手语叙事片段大小的实证研究、以研究为基础的课程设计实务及电脑技术，以发展一套有效的程式，教授失聪及重听学生核心的物理科学内容。这个项目通过有效地向依赖美国手语的学生展示材料来解决听力受损教学的关键问题；组织物理内容，促进掌握和更高层次的思维；并有效地克服了当前听障产品中常见的技术问题。在第一阶段，将制作六个原型课程，一个实验室和两个活动，并对不同年龄和英语/美国手语能力的初高中学生进行评估。原型机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，将开发一个完整的65课核心概念物理科学课程，并在随机对照试验中测试其有效性。拟议的商业应用：该项目将导致初中和高中的核心概念物理科学课程的第二阶段的发展，为聋哑和听力障碍的学生。课程内容包括动画、课文和美国手语解说、词汇练习、实验和活动。该产品将吸引那些招收聋哑和听力障碍学生的学校。此外，它将对聋人和听障教师培训机构有效。

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.
