Research And Practice Of Multisim In Analogous Electric Teaching Of Secondary Vocational Education

With the development of the modern science technology and the popularity of the computer, the computer assisted instruction has already obviously shown its superiority in education and teaching, which prompts education to reform itself, resulting in a huge change in teaching methods and teaching modes, and has greatly promoted the progress of education. In analogous electric circuit teaching, due to the existing disadvantages, the traditional teaching mode and the teaching method can hardly demands of modern society to education. It is required for us to introduce advanced equipments to carry on the reform of traditional experimental teaching mode and methods, with the direction of scientific teaching theories and learning theories.Thought analyzed the theory of constructivism and theory of system science. As well as discussing the characteristics of vocational analog circuit courses and the problems widespread in teaching, the paper presents the necessity and feasibility of introducing computer aid teaching with the conduct of constructivism. Multisim software is introduced into the three important teaching taches: the class teaching ,and practice teaching ,on analogous electric circuit of secondary vocational education. By practicing and exploring the proposed ssumption, this article comparatively analyzes the experimental effect, and proposes the fundamental reason for developing the scientific research.Three parts are included in the paper. In the first part, the paper briefly presents the general standpoint of the teaching theories such as CAI and the theory of constructivism, and it analyzes the widely existing in analogous electric circuit teaching of the middle occupational school, the necessity and possibility of applying CAI to teaching. Through the theories research, it puts forward the assumption of the optimizingteaching. In the second part, it explores the practical teaching mode in which the Multisim software is applied to the theoretical and experimental teaching and the research of applied theories in occupation school under the theory of constructivism, and thus to draw three conclusions about the optimization of analog circuit teaching: first, the abundant study situations which we established in the theoretical teaching would be advantageous for create something and to change their passive learning activities into active investigation, and help to resolve the problem that teaching time is always limited, and it contributes to the reform of education, keeping the content of course always up to date. Secondly as for the experiment class, the mode would enable students to preview and review the experiments conveniently, and train students' creativity; the hours for experiments will be no longer too tight. Thirdly, it could shorten the experiment design cycle, and promote the stability of designing electric circuit, thus to realize the student's designing thought. The paper also provides some typical teaching cases. In the last part, on the basis of summarizing the process of introducing Multisim software to the teaching practices, it points out some shortages and puts forward problems to be studied further. Through the attempt and the exploration of the Multisim software in analogous electric circuit teaching practices. The full paper illuminates the necessity and the importance of CAI from one side.
