Abstract:	「地球運動」的學習內容對大部份國小兒童而言，易形成迷思概念，而虛擬實境支援經驗學習、發現式學習等學習理論，又能夠以不同角度去觀察現象，在解釋物體的空間關係及變化過程佔有優勢，所以在教育上的應用有很大的潛力。本研究旨在以虛擬實境來發展教材並設計教學策略及學習活動，將虛擬實境實際應用於國小地球運動課程之教學中，協助學生釐清地球和太陽的運動、日夜及四季的形成等迷思概念，希望藉此瞭解其學習效益，以及虛擬實境對教與學的影響。首先進行課程需求分析，了解未融入虛擬實境教材前之教學困難，以及虛擬實境的優點及限制，再依此以虛擬實境來發展教材，並且設計虛擬實境之教學策略與教學活動。虛擬實境教材是提供一個豐富資訊、讓學習者可以動手探究、觀察、發現的學習環境。在教學策略及學習活動的設計方面，則以引導學生在虛擬環境中發現知識為原則。本研究的實驗對象是台北縣某國小六年級的學生共21人，包括7位女生及14位男生，總共上課6次，教學時數共500分鐘，其中實際操作此一虛擬實境教材的時間有255分鐘(佔51%)。研究工具包括前測及後測所使用的同一份兩段式成就測驗，用以分析學生的學習成果；在課程期間，以錄影、筆記、照相等方式做課堂觀察，並於課程結束後對師生進行訪談，再以問卷做態度及系統使用調查，藉以了解虛擬實境支援老師教學的程度，以及學生使用虛擬實境的經驗及反應。依據研究結果顯示，學生的學習結果有顯著的成效。研究發現之重點概述如下，在以虛擬實境發展教材方面，本研究提出在環境設計的自由度及視角切換上需取得平衡的考量、需提供充分的資訊及輔助支援給學習者、需精準計算模擬環境中的重要數值等建議。在應用虛擬實境於教學方面，老師及同學皆肯定虛擬實境是一種有用的教學工具，並從實際動手操作中，清楚了解地球運動中各種運作的歷程及現象，另輔以網頁、flash動畫等教材在呈現內容資訊方面的優點，可彌補虛擬實境無法呈現太多文字資訊的缺憾。另方面，虛擬實境教材需配合教學策略及學習活動，並與其他形式之教材做互補教學才能使虛擬實境的教育價值發揮地更好。本研究的結果，希望作為有效發揮虛擬實境的教育特質，以及提高「地球運動」課程教學效益之參考。 The concepts of “earth motion” in Astronomy are misconceptions for most pupils. The virtual reality is a potential educational tool. So in this study, we developed a learning environment and designed activities integrated with virtual reality, and implemented in the earth motion curriculum for the elementary students. The purpose here is to explore a little further into the effectiveness of teaching and learning with virtual reality. The study was conducted to evaluate the effect after the development. 21 students in grade six participated in the study to learn earth science through this curriculum integrated with virtual reality. The results show that there is a significant difference between pretest and posttest. This curriculum we developed can assist children to clarify their misconceptions. According to the conclusions of this study, the following recommendations are purposed for developing virtual reality environment: the necessary of sufficient information and assistant aids on object, the balance consideration between the freedom environment and the clear views, and the calculation accuracy of the environment. The main findings of applying virtual reality in the teaching can be described briefly as follows. It was agreed that virtual reality is a useful instruction tool, because it showed the whole process through learning by doing and helped students to understand the astronomy phenomenon. And assisting virtual reality with webpage, PPT, and flash animation’s material can recover the drawback of the 3D virtual reality with displaying information.
