網路虛擬同步加速器光源建置及其教學應用

本論文主要目的，在研究如何應用Web3D和虛擬實境等技術來建置虛擬同步加速器光源網站，以供國中、小學生參觀與學習之用。此虛擬同步加速器光源是模仿國家同步輻射研究中心的設施所建造，共分成四個主要場景：第一個場景是大廳，提供學習者通往其它區域之入口；第二個場景是控制室，以互動式操作介面加上文字介紹同步加速器的出光流程；第三個場景是設備區，裡面展示了同步加速器的各項主要設備，並以電腦模擬電子通過各項設備的情形，讓學習者能夠觀察行進間的電子放射出光束的現象；第四個場景是實驗站，本研究以古蹟鑑定為例，讓學習者在此進行虛擬實驗，以瞭解同步加速器光源亮度高且能顯示物質內部細微構造的特性，並藉此模擬情境體驗同步加速器光源與一般光源之差異。本研究將虛擬加速器光源網站融入國中、小「自然與生活科技」領域教學，以瞭解學生的使用態度及意見，研究結果發現：．網頁內容方面：國小高年級學生認為網頁內容非常豐富，而國中學生則認為網頁內容可以更詳細的解釋物理現象。．介面與設計方面：虛擬實境網站操作簡單、內容有趣，能讓學生想進入參觀，若以小地圖之方式導引將更為方便使用。．多媒體特性方面：透過3D動畫逼真的特性，能夠引起學習興趣，但需考量教學環境之電腦硬體與網路限制。．回饋與支持方面：3D動畫輔以文字說明及提供象徵性之圖示，在探索與學習的過程中扮演建構抽象概念的重要角色。．吸引性方面：透過任務導引與互動式虛擬實驗，可吸引學生想要使用虛擬實境網站去學習科學新知。建置符合師生需求之虛擬實境教學網站可以輔助課堂教學，且能符合科學教育中「觀察」之教育理念，並能藉此引發學生對課程的學習動機。本研究透過虛擬加速器光源的建置和數位教材的研發，將加速器光源的知識和概念，融入國中、小「自然與生活科技」領域的課程中，讓這群未來的使用者瞭解加速器光源應用在各種科學領域的可能性，並從小培養探究這項尖端科技的興趣。

The major purpose of this research is to study how to use Web3D and virtual reality technologies to build a virtual synchrotron light source website for elementary and junior high school students to visit and study. The design of virtual synchrotron light source was based on the National Synchrotron Radiation Research Center (NSRRC) at Hsinchu, Taiwan, and it contains four main scenes. The first scene is the hallway to provide the entrance to all other areas. The second scene is the control room, providing interactive user interface and texts to explain the operational process of synchrotron light source. The third scene shows the representative equipment of the synchrotron light source, using 3D animation to simulate electrons passing through the equipment to produce synchrotron light. The fourth scene is an experimental station, where learners can play the role of a researcher to identify antiques. Learners will discover that the high brightness of synchrotron light source can show the internal structure and composition of materials. They can also understand the difference of synchrotron light source and general light sources by doing virtual experiments. The results of this study include the attitudes and opinions of students after using Web3D virtual reality website as following: ．Web content: the elementary school students believed the web contents were very rich, and the junior high school students thought the web contents could be more detailed in the explanation of physical phenomena. ．Interface design: the website provided interesting contents to allow students to browse, and it would be more appropriate if the virtual scenes could be guided by a small map. ．Multimedia features: 3D animations with lifelike characteristics could usually enhance students’ interest in learning, but one needed to consider the restriction of computer and network in learning environments. ．Feedback and support: 3D animations, texts and provision of symbolic icons played an important role in developing abstract concepts in the process of exploration and learning. ．Attraction: the guidance of task and interactive virtual experiments could attract students to use Web3D virtual reality in learning new knowledge. This research built a Web3D virtual reality website according to the requirement of teachers and students to support classroom teaching, which conformed to the ＂observation＂ concept of science education and could enhance the learning motivation of students. This research integrates the knowledge and concepts of synchrotron light source into the curriculum of Science and Life Technology in elementary and junior high schools by developing the virtual synchrotron light source model and its digital learning contents, hoping to increase the interest of elementary students in discovering and learning this advanced technology.
