The Practice of the Electronic Technology Practicing Course in the Cold Collection of Electronic Technology Selling and Exemption Conference of Beijing Yizhi Electronic Technology Co., Ltd. Cao Lugong, Tan Changsheng, Qi Xiaoping, Liu Peichao (Department of Electronic Technology, Medical Engineering Department, Beijing Military Medical College, Beijing 100071, China 1 * The new type of electric cups and new medical equipment, persuaded the medical XS (maintenance) specialist to say that cultivating students ’electronic technology application ability and engineering practice ability has become the focus of electronic technology teaching. To achieve this training goal, the experimental class is completed The content can neither be the "verification experiment" of the auxiliary theoretical class or similar to the "factory internship". For a long time, the experimental teaching of the four electronic technology courses in our room is basically attached to the theoretical class, and the experimental content is often theoretical knowledge. Verification and supplementation.
You Xiang's teaching system is adjusted. We teach the theory of Wei in the electronic finance class and the theoretical teaching. To avoid the crotch of electronic technology, we start by revising the teaching concept and break the original electronic technology courses. The experimental division of labor has made a new plan for the content and arrangement of the experimental teaching, and the comprehensive lung method for the organization of the experimental teaching and the test for the ship experimental teaching have been comprehensively covered, and the teaching system for the thief has been deleted. Wei's two-year teaching practice proved that the hips are good.
In order to adapt to the new teaching system, we have revised the electronic technology experiment syllabus. In the revision of the syllabus, we have enriched and adjusted the content of the electronic experiment, so that its electronic technology practice is integrated and standardized in the new In the syllabus, it is clear that the electronic technology experiment course is an examination course. By separately organizing the assessment and recording the results, the form can make the students pay more attention to the study of the experiment class, which is conducive to the quality management of the experiment teaching. The new syllabus fully reflects the many Experimental teaching at different levels, including: (1) The basic vehicle experiment of the instrument, such as: the working principle and shed method of the organ, the working principle of the signal source and the method of using the experimental learning machine, etc.
(2) Confirmatory experiment of basic theory. Such as the measurement of AC amplifier circuit and Av, the measurement method of frequency characteristic of amplifier circuit, the application of operational amplifier, combinational logic circuit and integrated decoder, etc.
(3 Clear design experiments for students to choose. For example, voice-activated flash circuit, membrane switch circuit, programmable amplifier circuit, wired intercom, logic test pen and frequency habit conversion.
(4 large-scale comprehensive skill experiments such as assembling radios, digital frequency meters, and EDA circuit simulation design experiments.
2. Optimizing the teaching content The design ideas for the optimization of the teaching content of the electronic technology experiment course are: a single basic confirmatory experiment, combining related technical projects, adding a "design" experiment, enriching and perfecting comprehensive skill training, and strengthening the student's electronic engineering application skill. In the teaching process of this electronic technology experiment course, we made partial adjustments to the teaching content, and compressed and merged the single basic confirmatory experiments to compress and merge the original 20 basic confirmatory experiments into 16. Save 8 hours, add 4 sets of 32 “designed†experiments for students to choose. In “designing experiments, students’ stomach experiment requirements, use M ’s knowledge of iP wave skills, manuals, and materials to design circuits. , And then complete the experiment in the laboratory. Through the "design" experiment, students can learn the practical work skills of electronic technology nrn personnel through theoretical and practical connection.
By optimizing the content of experimental teaching, students have not only expanded their knowledge in the teaching of electronic technology experimental classes, but also "designed experiments, wings", comprehensive Weiwei "practical planning and open laboratories, strengthened the hands-on diligence and analysis, problem solving skill.
3 Reforming the Electronic Practice | Setting the crotch, changed the pattern of experimental teaching attached to theoretical teaching, and changed the favorable conditions for the content and methods of practical learning. In order to improve the teaching quality and effect of the electronic technology experiment class, we have done a comprehensive work on the concept of experiment teaching, the use and management of the laboratory, the organization, implementation and examination of the experiment while optimizing the teaching content.
(1 Qi experiment teaching is not necessarily synchronized with theoretical teaching. In the past teaching, because the experimental class is attached to theoretical teaching, the experiment must be arranged in accordance with the arrangement of theoretical teaching, that is, the experiment in the theoretical class can only be done. The experimental teaching arrangement will make students have a mentality to passively participate in the experiment. When doing experiments, it is more to compare and verify the theoretical knowledge, which is not conducive to the cultivation of students' comprehensive solid ether energy and innovation awareness. In this electronic technology experiment class, we are conscious It has changed the progress of the experimental class and theoretical teaching, and even multiple experiments are arranged before the theoretical class. After two months of teaching practice in this issue, this experimental teaching arrangement is feasible. Due to the content of experimental teaching The arrangement of Pan Yan is not limited to theoretical teaching. The teaching arrangement is flexible and self-assured. At the same time, because some of the experimental content is ahead of schedule (the experiment of 2 membrane pseudo-electronic circuits and digital electronic circuits is carried out at the same time. There are three laboratories in our laboratory 12 sets of instruments and equipment. Due to the limitations of the experiment site and equipment, each single experiment can only carry out 12 groups at the same time, with 80 people two The calculation of the test rounds, each should be arranged for 3 to 4. In order to improve the quality of experimental teaching and the utilization of experimental equipment, and increase the chances of practical hands-on students, in this electronic technology experiment class, we tried electronic circuit experiments and numbers A new way for electronic circuit experiments to be carried out in two laboratories at the same time. This method of organizing experimental teaching can reduce the number of classes, and the number of people in each experimental group can be reduced to two, increasing the chances for students to operate experiments.
(3 Jing opens the laboratory with the student's self-study time. After the independent establishment of the electronic technology experiment, the enthusiasm of teaching and learning is mobilized. During the design experiment and comprehensive experiment, especially on the eve of the experimental assessment, the student hopes to open the laboratory during the self-study time During the opening of the laboratory, the enthusiasm of the students is very good. There are often students waiting in line outside the laboratory to wait for the opening of the laboratory. Students can come to the whistle for the need of Btglg. It is difficult to overcome the disadvantages of experiments that have been done before but have not been fully understood to consolidate the learned knowledge; some students specialize in learning the application of oscilloscopes and instruments and devices to improve their practical skills. Xianying, it is an indispensable supplement to experimental iology.
(4 Weave a comprehensive electronic technology experiment exam. Arrangement of the electronic technology experiment course assessment independently is a stupid link to realize the integration and standardization of the experimental training and ensure the quality of teaching. By organizing the assessment separately, recording the scores, formally It can make the students pay more attention to the experiment, and it is also convenient for the quality management of the experimental teaching. The evaluation results of the electronic technology experiment are composed of three parts: the usual experiment, the comprehensive experiment and the actual operation assessment. The proportion of the usual experiment score is small (about 2) , But it is conducive to the management of the usual experiments. The proportion of comprehensive experimental scores of high teaching quality is relatively small (40%). Beijing fyzhi electronic technology sales practice will first meet the fmei annual meeting because it is a practical ability for students. , Comprehensive analysis of problem-solving and problem-solving skills. In the past, comprehensive experimental students asked the instructor if they had any questions, often without thinking more deeply. This year we made regulations. The "li" operation of the silver bank should also be deducted points. In this way, the instructor is not playing the role of "crutch", which is conducive to improving the self-determination of the students The ability to solve problems and troubleshoot. The actual operation assessment is a new teaching link after the independent establishment of electronic technology courses this year. The actual assessment requires each student to use the lottery to complete the experiment independently. The instructor based on the completion of the experiment and the questions answered by the students The items that are concealed for assessment and evaluation are part of the open unit experiment. For the student, the student carefully reviewed the usual unit experiment to master the practical theory, operating skills and correctness of the experimental equipment necessary for the electronic technology experiment. use.
4. Youyu â‘´ The experimental content needs to be enriched and adjusted. At present, the teaching content of the analog electronic technology experiment is still formulated by Shifeng. The newly added design experiment is not enough to standardize. Therefore, there is an urgent need to enrich and adjust the experimental content through the development of experimental equipment, and compile an electronic technology experiment guide book needed for the professional development of Sis * modern medical instrument maintenance.
(The strict arrangement of the 2nd degree study is yet to be standardized. Due to the limitations of the laboratory equipment, there are currently many arrangements. The maximum number is 4-5 people. For this reason, it is still to discuss new teaching arrangements for real brewing square pieces.
