| The cultivation of "applied-type" talents has become the basic objectives of China's highervocational personnel training. Experimental teaching is the key of fostering practical talents.However, in our higher education, there are many problems in experimental teaching. For along time, the experimental teaching system formed by the limitation of economicdevelopment level and traditional education and teaching ideas has the followingshortcomings: in terms of guiding ideology, focusing on the theory and knowledge andmaking light of practice and engineering; as for the course structure, experimental classes areattached to various theory courses. Priority has been given to the replication experimentcharacterized by relative dispersibility and isolatism, and poor relevance and systematicness.Laboratory equipments are also designed for each course, and there are few comprehensiveand designed experimental content.To improve students'ability of comprehensive use of knowledge and practical engineeringapplication, strengthen the links among curriculums and the application of knowledge system,the author designs and develops the "comprehensive training system platform for electronictechnology." This system mainly designs the DDS-based high-frequency signal source,wireless AM transmitter system, wireless AM receiver system, liquid crystal display module,keyboard control module and so on. The interface is reserved for each module to help studentscomplete the experiments of integrated application of appropriate analog circuits, digitalcircuits, high frequency circuits and SCM, so as to help students flexibly apply the knowledgelearned. The practical test shows the indicators of the system meet the design requirements,and it has good practical value. |
