Researches On Dynamic Drawing Sub-system Based On Knowledge Components

Computer Aided Instruction system plays an important role in modern education technology, especially in the field of education informing processes. From the point of macro view, CAI plays an important role in both of the process of the deep-going reform of education and the propelling of quality-oriented education. From the point of micro view, CAI can not only help teachers teaching, but also assist students studying. As the influence of different technologies in different period of time, the developments of CAI are diversities, such as the representations of multimedia and intellectualization. Based on the of mechanical proving theory in artificial intelligence, an intelligent education platform development model of ICAI is put forward by Zhang[1], which is more intelligent and humanity compared with traditional CAI model. A new research field of CAI is opened in the CAI studying world.Based on the intelligent education platform concept of physics [2], the dynamic drawing system is researched and some knowledge elements are carefully studied at the background of the junior high school, especially on the force and mechanical knowledge units. They are also the bases for the future expanded researches.In this thesis, the subjects of the CAI development, the theoretical background of our research, the researching architecture, the design and realization of an experimental sub-system are discussed carefully. In the first two chapters, the history of the development of CAI is reviewed, their current situation is summarized, some related teaching assistant software are discussed and compared, the main features of multimedia and the function structure of intellectualization are analyzed. At last, the historical backgrounds and theoretical base are analyzed, the essential structures are dissected and the key terms are explained as well. In the following two chapters, the design and realization of this system are discussed as follows: the design proposal, the technology analysis and the realization steps, etc, are presented. Besides, the dynamic drawing sub-system is realized, especially on the specific situation calculation and demonstration of part physical components exchange within the ken of force and machinery knowledge. In the last chapter, the summarization of this thesis is done and the future researching plan of this subject is discussed.
