| Summary: | 碩士 === 國立政治大學 === 資訊科學學系 === 92 === The objective of this research is on developing a Web-based educational system with intelligent media to enhance learners’ learning effects, especially to facili-tate learners’ spatial reasoning on learning spatial geometry topics. The increas-ing computing power allows us to use computers as powerful educational media. Based on theories of pedagogy and educational media, we propose to integrate intelligent media into typical Web-based learning paradigm to improve learning. “Intelligent media” in this research refers to two aspects of considerations. They are media─cognitive media aspect and method─intelligent tutoring aspects. The consideration of cognitive media aims at offering learners the most ease-of-understand presentation of a particular domain. The consideration of in-telligent tutoring targets to offer learners personalized learning experience based on individuals’ learning needs. To achieve better abstraction and flexibility in the adaptive mechanism, we have chosen to separate the concept sequencing from the underlying task of selecting appropriate learning materials.
By considering the characteristics of spatial geometry concepts, a Web-based learning environment called CooTutor (Coordinate Tutor) for learning spatial geometric transformation (SGT) is developed. Interactive 3D media is integrated into the system for delivering domain concepts effectively. Since the domain, spatial geometric transformation is evidently related to spatial ability (a group of human abilities about the use of space). This research attempts to address the relation between spatial ability and interactive 3D media via experimental evaluations. Moreover, learners’ latent traits, including spatial ability and learn-ing styles are considered to be used in adaptive material selection.
The main contribution of this research would be (1) the conceptualization of in-telligent media and the M&M concern for effective Web-based learning, and (2) an innovative approach and tenable architecture of employing 3D computer graphics and adaptive technologies in Web-based learning context for SGT learning.
