Abstract
近年來由於科技不斷的創新及改變，將擴增實境的技術運用在教育上受到許多學者討論與應用。擴增實境以其具有將真實物件與虛擬資訊結合並產生互動的特性，創造出一種新形態感官體驗的學習方式。在眾多的應用中多數都以單影像的方式呈現，對於需要將多種概念產生關聯的議題難以同時呈現。因此本研究將擴增實境具有的特色，運用在自然科學課程的潮汐與月相變化單元中，設計一個連動式多影像擴增實境潮汐模擬系統，本系統的「連動式」是指畫面中所呈現的四個視窗畫面具有連動的功能，依據學生操作月球與地球模型轉盤，視窗畫面能同步隨著使用者旋轉模型的角度變化跟著產生相對應的影像位置變化，「多影像」則是指將四個表達不同概念的影像畫面同時呈現在一個畫面中，藉由連動的方式讓四個畫面同步產生相關聯的變化，讓學生透過操作月球與地球模型轉盤，觀察月球公轉時，對地球潮汐變化及海水平面漲、退潮的多重概念。
本研究主要利用擴增實境技術，探討建置一個連動式多影像擴增實境系統時，需要考慮的因素與限制，並探討系統運用在教學活動時，使用者對系統的操作介面、顯示介面的滿意度及使用意願之研究。利用ADDIE模式，透過分析、設計、發展、實施及評鑑等階段開發此系統，並以問卷調查及訪談方式，探討使用者對系統的操作介面、顯示介面的滿意度及使用意願。
研究結果顯示，學生對連動式擴增實境教學系統的操作介面認為：在操作上並不會困難、系統整體的運作流暢、互動性良好；對系統顯示介面使用多視窗顯示方式呈現的訊息更能讓學生瞭解、能把月球運行對潮汐變化的影響關聯在一起、每個視窗所呈現的訊息都能清楚表達意義；利用AR輔助教學的學習方式覺得有趣、可提高學習興趣、願意再次使用。希望研究的結果能對後續開發建置多影像擴增實境系統融入其它議題時，互動介面設計之參考。
In recent years, Augmented Reality (AR) has been widely employed in educational settings. By displaying virtual images/animations that superimpose onto the real objects, AR is capable of achieving interactive simulations. Most instructional ARs developed so far only dubbed a single interactive AR image onto a single object, however, more complicated concept learning may require liking two or more correlated phenomenon. The correlation between the revolution of moon and tidal effects on earth is one of such correlated concepts. In this study, a multi-image instructional AR toolkit was developed that is capable of synchronously illustrating the relation of moon revolution and tidal effects. By rotating the earth-moon physical model, students will be able to view on computer screen the phases of the moon and coordinated tidal effects on earth synchronously. The ADDIE (Analysis, Design, Development, Implementation, and Evaluation) model was used for the construction of the purposed AR instructional toolkit. Student’s satisfactions on AR operations, screen interfaces, and desire to use the AR toolkit were analyzed by questionnaire surveys and interviews. The results of this study would inspire the development of more innovative AR toolkits for instructional applications.
