| Summary: | 碩士 === 國立中央大學 === 網路學習科技研究所 === 94 === In this paper, an innovative and manipulative learning tool was proposed. We called it “Web3D Virtual Classroom System”. We used it to improve geometry problem solving based on the pedagogical theory: “The learning representation mode is from the concrete items to abstract ideas through physical or mental manipulation“. In Taiwan 9-year integrated curriculum syllabus, emphasizing the importance of learning geometric concept through real life experience. By that we hope for children can find the factors and relations from different kinds of geometric objects, and then to construct correct geometric concept. In recent years, the Virtual Reality technology has been applied in military training and video games etc., but it was rarely employed in formal educational context. And especially for geometry learning, learners should promote their understanding through coordination, integration and structuring activities with geometric objects.
For above reasons, we have developed “Web3D Virtual Classroom System” by integrating virtual manipulative and multimedia whiteboard. That was mean learners can solve geometric problems with manipulating objects, and propose their solution on multimedia whiteboard. Furthermore. And we also involved the asynchronous cooperation by introducing peer assessment and solution revision mechanism.
This paper was divided into two parts. In first part, we described literature discussion, system design and system development. In the second part, we investigated perceived acceptance of proposed system and students' solving methods from two system studies. The questionnaires' result showed that subjects agreed our proposed system is useful and they also had positive attitude to ease of use.
