MULTIMEDIA EARTH SCIENCE PROGRAM FOR HEARING IMPAIRED

聋哑和重听学生学习成绩差， 特别是在科学领域，这在很大程度上归因于不适当的科学， 假设学生既能听又能读的材料。 此外，委员会认为， 教学效果往往很差，因为教师不足以 在这一人群的沟通需求方面受过训练。 该项目将 将最新科技发展与以研究为本的教学结合起来 向聋人和有困难的人教授核心地球内容的做法和方案， 听力学生 这个项目解决听力的关键问题 通过以下方式削弱教学：有效地向学生呈现材料， 多样化的美国手语、英语阅读和听力能力;组织科学 内容有助于掌握和更高层次的思维;和效率 克服当前常见的重大技术问题 听力受损的产品。 在第一阶段，我们开发了四个原型地球科学课程， 独立的交钥匙系统，包括视盘、计算机、监视器 键盘和耳机。 这些经验教训经过实地检验， 对10名具有广泛ASL的中学生进行评估， 英语阅读和听力能力。 在第二阶段，我们将a）完成一个50课的序列，包括 地球科学中的全部关键内容，以及B）进行 随机对照试验，以评估该方案的疗效。 建议的商业应用：该项目将导致阶段 制作一个初中和高中地球科学节目 为聋人和听力困难的学生。它将包括视频材料 与ALS，文本的不同阅读水平，和音频增强。它将 对州、地区和当地的聋哑学校有吸引力， 听力学生，以及培训教师的机构， 又聋又聋

Poor academic performance among deaf and hard of hearing students, particularly in science, is greatly attributable to inappropriate science materials that assume students can both hear and read. Furthermore, instructional delivery is often poor because teachers are inadequately trained in the communication needs of this population. This project will incorporate recent advances in technology with research-based teaching practices and programs to teach core earth content to deaf and hard-of- hearing students. This project addresses critical issues of hearing impaired instruction by: effectively presenting material to students with diverse ASL, English reading, and hearing abilities; organizing science content to facilitate mastery and higher order thinking; and efficiency overcoming significant technological problems common in current hearing-impaired products. In Phase I, we developed four prototype earth science lessons using a stand alone, turn-key system including videodisc, computer, monitor, keyboard, and headphones. These lessons were field tested and evaluated with ten middle school students having a wide range of ASL, English reading, and hearing abilities. In Phase II, we will a) complete a 50-lesson sequence that encompasses the full range of critical content in earth science and b) conduct a randomized control trial to evaluate the efficacy of the program. PROPOSED COMMERCIAL APPLICATION: This project will lead to the Phase II production of a middle school and high school earth science program for deaf and hard-of-hearing students. It will incorporate video material with ALS, text of different reading levels, and audio enhancement. It will be attractive to state, regional, and local schools with deaf and hard-of- hearing students, as well as to institutions which train teachers of the deaf and hard-of-hearing.
