The Research Of Vocational Education Electron Technique Virtual Experimental Teaching's Study Environment Design By The CAS Theory

With the development of CAI (Computer-aided instruction), the research on individual teaching has changed from the simple adaptive system to the complex one. In simple adaptive system, the student's study step is planed by teachers and the study content followed step is selected based on student's reaction. However, in complex adaptive system, various teaching variables (quantity, type, order, exercise and feedback of teaching content) is adjusted based on student's various study variables (preparation knowledge, present knowledge and interest, etc.)In the background of the reform of vocational education experiment teaching, based on the teaching characteristics of electronic technique virtual experiment and actual status, aimed at the education of students'synthesis quality, learning capability, innovation capability and behave criterion, the learning environment design of electronic technique virtual experimental teaching in vocational education is discussed in this thesis with the supporting of modern educational technique and the CAS theory. Directed by theories of mix-learning, teaching design and educational media and in the view of interacting and mutual adapting between learner and studying environment, the design idea to electronic technique virtual experimental studying environment is conducted based on the learner's adaptability grow in the interaction course with studying content, media platform, teacher and other learner in the environment. Such a adaptability optimization of studying environment will improve studying efficiency and teaching effect. At the same time, for such a complex adaptation system, concerned research will advance optimizing of course resource, improve teacher's teaching capability and electronic technique course system in the electronic technique virtual experimental teaching.The Multisim2001 virtual experimental software's function is powerful, it's interface is friendly and it is easy to lenrn and use. It's powerful and convenient stimulation function provided us a wonderful operation possibility and important foundation platform for carrying the design research of electronic technique virtual experiment studying environment by the CAS theory. Not only for choosing and renewing the experiment program, but also for basic and extent to every experiment, the Multisim2001 will meet the learner's demand for the environment. The application part of this thesis focused on the constructing of studying environment and an example of experiment teaching. The teaching design thoughts and practice of electronic technique virtual experimental teaching is described and our research is summarized and reconsidered by evaluating of studying environment.
