| Summary: | 碩士 === 臺中技術學院 === 資訊科技與應用研究所 === 97 === 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.
