Design And Application Of Interactive 3D CAI Courseware

With the rapid development of computer hardware and software,3D CAI courseware is gradually rich in content.The degree of its application is more and more deeply.Interactive 3D courseware can reveal the non-intuitive,abstract form of structure,rules and principle of the content of teaching.It combines the knowledge points in textbooks and three-dimensional space structure,and changes the set thinking of the 2D space formed by the learner in the learning process.Compared to the traditional multimedia courseware,3D CAI courseware has its own unique advantages,such as immersion,interaction,autonomy,etc.Therefore,researchers from the sector in the field of education gradually put more and more attention to it.Interactive 3D CAI courseware is the type of interactive operation.It combines a variety of technologies,such as multimedia technology,3D animation technology and VR technology,etc.This courseware can create an object model realistically,and reproduces the spatial structure of the object and sports relations.What's more,it has highly interactive operation,and can achieve two-way transfer of information,including the transfer,exchange and feedback,between the user and the computer.This paper systematically describes the basic concepts,elements and design principles of 3D CAI courseware.Under the guidance of the integration of information technology and Curriculum,it summarizes the development 'process and functional structure of interactive 3D CAI courseware.This article explores the courseware design inspired from the situated cognition,teacher-led and learner-centered teaching model and the law of creative thinking theory.Moreover,it makes a needs analysis,instructional design,scripting,and functional structure design for interactive 3D CAI courseware.By analyzing of the status of tools and the technical characteristics of 3D courseware,this paper describes the steps of creating and displaying the 3D model scene,animation and interactive features based on WPF 3D.Finally,according to the proposed design and development process of the interactive 3D CAI courseware,the specific knowledge of the Earth moving parts in the high school geography is selected as the courseware content.From the starting of the needs analysis for the courseware,the last section of the article clears courseware knowledge of the entire body of knowledge.And it sets the goal of teaching,designs the courseware script,and completes courseware by the WPF 3D.At last,the paper shows the realized effect and evaluates of the courseware.This paper systematically studies the design and production process of the interactive 3D CAI courseware.It provides theoretical guidance and technical support for the first teachers in producing 3D Courseware.The study not only has practical significance for the development of CAI courseware,but also is important practice of the integration of information technology and curriculum.And it also is the deepening of the applications of virtual reality technology in the field of education.
