The Design And Development Of Computer Aided Instruction

At the information age, with the development of sci-tech and human society, and faced with the challenges of information economy and international competition, education has become the basis for a nation's development. It has become a historical mission to deepen the educational reform and train people with creativity and practical ability. The development of modern educational technology, especially the wide application of information technology based on multimedia and the web in the educational area, has shown an unparalleled priority over the traditional educational media. It plays an irreplaceable role in the process of educational striding development in the modern society where informationalization pushes educational development.Based on the development of multimedia and the web as well as their impact on educational reform, this article puts forward the issue that multimedia and web technology should be widely applied in medical-college education to reform the traditional teaching models and establish new ones. Reform on teaching structure and teaching models is an important task in the educational reform nowadays. To create new teaching structure and teaching model, a necessary precondition is to reform the one-way-information-transfening resource environment. CAI courseware is an important and practical teaching source. The key point of the article is the design and program of CAI courseware.The second part is the core of the article. The implement of CAI teaching mainly depends on CAI courseware . The article presents the definition and characteristics of CAI courseware; then lists the main type of it; and lastly with the help of practice on CAI courseware research, this article mainly discusses such issues as designing principles of medical CAI courseware and the basic procedures of CAI courseware design, including definition of problem under discussion, teaching design, design of system function, design and modification, tryout and evaluation, etc. In the definition of problem under discussion, the necessity to use courseware is demonstrated from the angles of the need of the society and of the students, and its practicality. Accordingly, the issue of course subject choosing and orientation can be determined. Teaching design mainly includes the analyses of teaching objects, teaching content, teaching aim, teaching strategy, teaching media, and the final written manuscript. System design includes designs of structure, navigation, interface, interaction and the final produced script. The practical production refers to the practical realization of CAI teaching software, including the preparation and production of material aswell as the compilation and synthesis of software. Evaluation and modification refer to the trial operation of CAI teaching software and the modification of its defects and limitation for the purpose of perfection. Besides, I also summarize the experience and lessons I got when I produced medical CAI teaching software.The last part of the article discusses the application of CAI teaching software in medicalteaching. First of all, it discusses the application of multimedia technology as well as its impact on educational reform, especially in teaching structure and teaching models. The rapid development of multimedia technology provides advantages for the creation of new teaching structure and teaching model. In order to discuss the topic deeply, it is necessary to explore the definition of teaching structure and teaching model and the principles of constructing teaching models, including principles of educational concepts and value orientation, guiding principles of educational theories, principles of course content and structure, principles of educational psychology and principles of educational technology. And then the main teaching models in medical teaching are enumerated, such as teaching model based on resource, teaching model based on problem. And the next section discusses the promotion of CAI to medical teaching reform in terms of teaching method and teaching c...
