摘要

合作式學習是近年來教育界著重的研究項目，合作式學習模式讓學生在學習的同時能夠發表意見，提問問題。合作式學習的方式，從最初的一群人聚在一起討論，發展到現在的網路合作式學習，例如視訊會議，電子郵件和討論區等等，儘管克服了距離上的限制，但就互動性而言，還是無法滿足使用者的需求。由於新科技的發展，我們可以很輕易的達成合作式的虛擬環境，使用者只需要一台個人電腦及瀏覽器外掛，即可進入虛擬實境的世界。
本研究以Extensible-3D (X3D)語言建構一個3D人體器官合作式學習系統(3D-HOLS)，利用X3D與Java程式語言，完成可供多人線上練習與討論的虛擬學習環境。系統以人體器官教學為主，使用者可以對3D的虛擬人體器官進行操作，並且利用系統所提供的功能進行合作式學習，創造更具效率的學習模式。本研究依據科技接受模式(TAM)及虛擬實境的特性設計問卷，並於使用者實際操作後，利用該問卷對本系統進行評估。
實驗的結果顯示，本研究所建構之3D人體器官合作式學習系統具有高度的融入性，表示系統成功的讓使用者沉浸於虛擬實境與合作式學習的環境當中。系統融入性成功的預測出使用者的認知易用性和認知有用性，並且提高使用意願。

Collaborative learning has been the focus of many education researches over the last twenty years. Collaborative learning allows learners to express opinions or ask questions while receiving information. Forms of collaborative learning have been evolved from traditional real person group discussions to Internet-based collaborations. Although spatial barriers had been overcome, interactivities provided by Internet-based collaborative learning systems had not yet met users’ demands. Fortunately, with the new Web3D standards, VR multimedia data and user’s control data can be easily transmitted over the Internet. Contrasting with traditional virtual reality, users only need a basic personal computer and browser plug-in to interact with the virtual reality environment.
In this research, we built an interactive and collaborative 3D human body learning system (3D-HOLS) by using Xj3D. Learners can obtain knowledge of 3D spatial relationship among human body organs. 3D-HOLS establishes a multi-user and multi-platform virtual learning environment. Under this environment, learners and instructors are able to perform collaborative learning and engage in group discussions regardless of their locations and types of computer systems.
In this study, we surveyed users who tried using 3D-HOLS. The questionnaire was designed such that it follows Technology Acceptance Model (TAM) and takes characteristics of virtual reality into account. The survey results indicated that 3D-HOLS is highly immersive. The system had successfully led users to immerse in the virtual collaborative learning environment. The system’s immersive feature positively influenced users’ perceived ease of use and perceived usefulness and increased users’ behavior intention.
