Web-based Multimedia Science Instruction for the Deaf

该项目将结合最新的硬件和软件的进步，一个行之有效的，多媒体科学计划，提供有效的基于网络的科学教学，在初中和高中的聋人和听力困难的学生。这类学生通常在科学方面表现出较低的学习成绩。科学成绩不佳的一个主要原因是使用了为既能听又能读的学生设计的科学材料。此外，聋人和重听人的教师往往没有受过美国手语的培训或培训不足，或科学背景不足。本项目将通过以下方式解决这些关键的教学问题：（a）使用互联网提供一个有效的科学教学计划，该计划提供专门为依赖ASL的学生设计的视觉丰富的多媒体内容，（B）组织内容以促进掌握和高阶思维，以及（c）使用互联网向学生提供这种教学。在第一阶段，将制作四个关于基础化学的原型课程，供网络交付，并对不同年龄和英语/美国手语能力的初中和高中学生进行评估。在第二阶段，将开发一个完整的30课核心内容化学课程，通过网络提供，并在随机对照试验中进行评估。拟议的商业应用：该项目将为初中和高中聋人和重听学生制作一门关于化学核心概念的网络课程。该计划将利用美国手语，多媒体，替代签署和文本水平，音频叙述结合一个有效的课程。这将吸引任何学校服务聋人和听力困难的学生在这些年级。

This project will incorporate recent hardware and software advances with a proven-effective, multimedia science program to deliver efficacious web-based science instruction to deaf and hard-of-hearing students in middle and high schools. Such students typically exhibit low academic performance in science. A principal cause of this poor science performance is the usage of science materials designed for students who can both hear and read on grade level. Furthermore, teachers of the deaf and hard-of-hearing are often untrained or poorly trained in ASL or have an inadequate science background. This project will address these critical instruction issues by (a) using the internet to present an efficacious science instruction program that provides visually-rich multimedia content specifically designed for students who rely on ASL, (b) organizing the content to facilitate mastery and higher- order thinking, and (c) making this instruction available to students using the Internet. In Phase I, four prototype lessons on basic chemistry will be produced for web delivery and evaluated with middle-school and high-school students with a range of ages and English/ASL abilities. In Phase II, a complete 30-lesson core content chemistry program will be developed, delivered via the Web, and evaluated in a randomized control trial. PROPOSED COMMERCIAL APPLICATIONS: This project will lead to the production of a web-based course on the core concepts of chemistry for middle-school and high-school deaf and hard-of-hearing students. The program will utilize ASL, multimedia, alternative signing and text levels, audio narration in conjunction with an efficacious curriculum. It will be attractive to any school serving deaf and hard-of-hearing students in these grade levels.
