Preparation of Interactive Digital TV & CD Earth Science Curricular Programs from Existing VHS Analog Vocanological and Geothermal TV Footage

美国国家地质调查局夏威夷火山观测站(USGS-HVO)的档案室里保存着世界上最杰出的一些夏威夷火山的电视画面。该项目将把这个优秀的模拟电视镜头的亮点，以及数百个小时的地热田镜头转换为数字形式，最多有十个节目编辑焦点，适合用于地球科学课程的互动背诵教学模块。这些制作的节目将包括提问/回答部分，在这些部分，观众可以停止、查看、重播节目，甚至可以使用这些节目来进行必要的视觉和时间测量，以回答叙述性提问的实验室风格的问题。因此，数字化使一些非常令人兴奋的互动教学和实验模块成为可能，而数字电视格式使这些类型的互动成为可能，比旧的AV/TV技术更容易。计划中的互动模块将利用火山学内在的视觉刺激，不仅教授地质学、环境科学和岩石学，还将教授相互关联的基本数学、物理和化学概念。该提案承诺了以下六项主要任务：(1)对10个30-50分钟长的火山/地热节目进行数字编辑，每个节目有互动的观众练习(2)对数字编辑的节目进行在校观众测试，特别注意互动部分；将对第4、10和大学水平的观众进行实地测试；(3)这些实地试验将为每个节目产生三个适合观众的互动部分；(4)这些数字准备的材料(包括数字电视和CD)将在全国GSA会议上的NAGT研讨会上介绍；(5)将通过网站技术安排尽可能广泛的免费分发课程成品，以及(6)将技术转移到数百小时火山和地热电视图像的数字数据库。

0003002UlmerVery likely some of the world's most outstanding TV footage of Hawaiian volcanology resides in an archive closet at the United State Geological Survey Hawaiian Volcanological Observatory (USGS-HVO). This project will transfer-edit the highlights of this excellent analogue TV footage, as well as many hundreds of hours of geothermal field footage into digital form with as many as ten programmatic editing foci suitable for interactive recitation teaching modules for geoscience curricular use. These produced programs will involve Question/Answer segments where the program can be stopped, reviewed, replayed and even used by the audience to make visual-and time measurements necessary to answer the narrative-asked, laboratory-style questions. Thus the digitization makes possible some very exciting interactive teaching and lab modules and digital TV format makes these kinds of interaction possible with far greater ease than older AV/TV technologies. The planned interactive modules will use the intrinsic visual excitement of volcanology, not just to teach geology, environmental science and petrology, but also to teach the inter-related basic math, physics and chemistry concepts. This proposal promises the following six major tasks: (1) the digital editing of ten, 30-50 minute long volcanological/geothermal programs with interactive audience exercises in each program (2) in-school audience testing of the digitally edited programs with special attention to the interactive segments; field testing with 4th, 10th, and college level audiences will be performed; (3) these field trials will lead to three audience-appropriate levels of interactive segment for each program; (4) these digitally prepared materials (both digital TV and CD) will be presented at NAGT workshops at national GSA meetings; (5) arrangement to guarantee the widest possible royalty-free distribution of finished curricular products will be performed by a website technology, and (6) the technological transfer to a digital data base of hundreds of hours of volcanological and geothermal TV images.
