3D虛擬儀器之合作學習系統設計

The Design of Collaborative Learning System for Operating 3D Virtual Instruments

近年來「合作式學習」在教育上是相當受到重視的學習方法，是一種結合教育學、社會心理學的分組教學設計，主要是利用小組成員之間的互相研討、支援、並分工合作進行學習。目前網際網路合作式學習系統的設計，大多是提供一個方便的網路環境，讓學生可以在線上進行理論課程的學習，卻鮮少提供在網路上透過3D虛擬實境進行儀器操作的網路合作式學習環境。本研究提出一個可操作3D虛擬儀器的網路合作式學習系統設計，系統結合虛擬實境、遠端控制參數傳遞及PC Broker設計等技術，架構一可在網路上合作操作虛擬儀器的合作學習環境。系統不僅提供學習者透過網路遠端連線共同實習操作3D虛擬電子儀器（訊號產生器、電源供應器等儀器），亦提供學習者即時文字交談討論及3D益智遊戲之合作操控等功能，並藉此培養學習者在合作學習的積極互賴特質，有效提升學習興趣，改善合作學習效果。

Recently, the academic community has been giving much attention to collaborative learning system, a group learning method combined with pedagogyand social psychology. It allows group members to gain knowledge through collaborations and interactions. Nowadays, most Internet cooperative learningsystems are designed to provide students mainly with a convenient online environment to study theoretical courses but rarely with a 3D virtual reality to operate practical instruments. Hence, this paper designed a 3D online collaborative learning system for operating virtual instruments. By integrating with virtual Reality, Remote Control Parameter Transmission and PC Broker techniques, this system gives learners not only a cooperative learning environment via networking to jointly operate the 3D virtual instruments (for example, signal generator, power supplies and oscilloscopes) but also the functions of instant messages and 3D puzzles to interact with one another. Therefore, learners can effectively improve learning interests and efficiency.
