MULTIMEDIA EARTH SCIENCE PROGRAM FOR HEARING IMPAIRED

聋哑生学习成绩不佳， 尤其是在科学上，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， 由于教师的能力不足，教学效果往往不佳 在这一群体的沟通需求方面进行了培训。这个项目将 将最新的技术进步与研究性教学相结合 向聋人和顽固人传授核心地球内容的做法和计划 听力好的学生。这个项目解决了听证的关键问题。 通过以下方式影响教学：有效地向学生展示材料 不同的ASL、英语阅读和听力能力；组织科学 内容促进掌握和更高层次的思维；以及效率 克服当前普遍存在的重大技术问题 听力受损产品。 在第一阶段，我们使用一个 独立的交钥匙系统，包括视盘、计算机、监视器 键盘和耳机。这些经验教训经过了实地测试和 对10名ASL水平较高的中学生进行了评估， 英语阅读和听力能力。 在第二阶段，我们将a)完成包含以下内容的50课序列 地球科学的所有批判性内容和b)进行a 随机对照试验，评价该方案的疗效。 建议的商业应用：该项目将导致阶段 制作初中和高中地球科学节目 为聋哑生和重听障学生准备的。它将包含视频素材 具有ALS，不同阅读水平的文本，以及音频增强。会的 对聋哑人和困难学生的州立、地区和地方学校具有吸引力 听障学生，以及培训教师的机构 耳聋，听力不好。

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.
