虛擬實境學習系統之設計與評估 以高職學生學習銑床為例

隨著科技軟硬體的快速發展，虛擬實境(Virtual Reality，VR)設備相對以前已有較好的體驗與相對親民的價格，使得VR正廣泛地應用於多個領域，如遊戲、影視、展覽、教育和安全訓練等。虛擬實境的應用有助於學習者沉浸於虛擬環境中，並提供較好的互動體驗。透過虛擬環境，學習者能夠進行問題探索、嘗試錯誤、把握重點，同時降低學習成本。本研究以「VR銑床學習系統」為例，根據高職生的銑床學習目標，設計系統的學習流程和互動內容。
研究的第一部分為「學習系統設計」，介紹學習系統的設計過程和互動內容。在第二部分的「專家評估」階段，由專家對本系統的內容正確性進行了評估，並從中獲取建議，以提升教材的互動性和知識傳遞效果。第三部分則是「使用者評估」，將受測者分為VR組和PC組，每組各30人，在使用過程中進行觀察法、易用性問卷進行質性分析。並且在VR組與PC組測試前後進行學習成效的測試與傳統教學進行學習成效比較。
研究結果顯示，此VR學習系統能夠有效提升使用者在銑床基本知識的學習成效。也能夠增強學習者的學習動機和興趣。PC則是較適合大型教學，因為其設備要求較為簡單。本學習系統教學內容結合模擬動畫、圖片和旁白說明，有助於學習者理解銑床的操作步驟。在互動物件增加輪廓線並以說明物件名稱與檔位狀態使學習者能加速理解內容。銑削火花特效和加工音效能夠提醒使用者關注銑床加工的高溫和危險性，促使學習者對該加工技能保持著嚴謹的態度，確保學習的安全性。本研究成果期望能為未來相關VR學習系統的開發和研究提供有益參考，以進一步豐富學習體驗並提升學習成效。
