As the main course of electronic information and communication engineering in colleges and universities, the teaching quality of high-frequency electronic circuits is directly related to students' learning efficiency and quality. Next is my paper on high-frequency electronic circuits, I hope it will help you.
This paper first introduces the teaching status of high-frequency electronic circuit course, and based on the analysis of the problems existing in teaching activities, discusses the feasible teaching reform countermeasures, in order to fundamentally improve the teaching efficiency and quality of high-frequency electronic circuit course.
High frequency electronic circuit; Curriculum reform; quality of teaching
As the main course of electronic information and communication engineering in colleges and universities, the teaching quality of high-frequency electronic circuits is directly related to students' learning efficiency and quality. In recent years, with the deepening of the concept of quality education, the disadvantages of traditional teaching mode in colleges and universities have become more and more obvious, and it has been impossible to successfully complete the teaching objectives. Therefore, it is imperative to reform the teaching mode of high-frequency electronic circuit course, which needs the attention of relevant departments of the school.
Problems existing in the teaching of 1 high frequency electronic circuit course
The teaching content of 1. 1 is limited.
As a course, high-frequency electronic circuit does not exist independently, but is closely related to other disciplines, such as circuit analysis, advanced mathematics, signals and systems, analog electronic circuits and so on. Therefore, if the teaching of high-frequency electronic circuits wants to achieve the expected goal, the above contents must be closely linked to form a complete teaching system. However, judging from the current teaching situation of high-frequency electronic circuits, the relationship between disciplines in the teaching process is not obvious, and even some disciplines are ignored. In recent years, the communication system, working frequency band and modulation coding mode of wireless communication in China have changed to some extent, and the circuit design needs to be optimized and improved again. The completion of this task must be based on the integration of new knowledge. At present, the teaching content of high-frequency electronic circuit can't meet this requirement, which leads to students' inability to grasp the practicality of this course and realize the application of what they have learned.
1.2 The teaching method is single.
"Teachers talk and students listen" is the main method of high-frequency electronic circuit teaching under the traditional teaching mode. Although this method can transfer knowledge to students to a certain extent, due to the lack of inspiration and innovation, students' mastery and understanding of knowledge is too simple to understand some concepts and working principles vividly. In this way, the knowledge system constructed by students will lack comprehensiveness and systematicness, and the learning effect will naturally be unsatisfactory. In recent years, the rapid development of computer technology and network technology has created conditions for the renewal and perfection of teaching mode and teaching method. Teachers can enrich teaching methods with the help of computer technology and multimedia technology according to the subject characteristics of high-frequency electronic circuits, which can not only arouse students' enthusiasm and initiative in learning, but also help students grasp knowledge points quickly and improve learning efficiency.
1.3 Theory is divorced from practice.
The organic combination of theory and practice is the basis of improving teaching quality, especially for the highly operational subject of high-frequency electronic circuits, practice teaching plays an extremely important role in teaching activities. In traditional teaching, although teachers are aware of the importance of practical teaching and set up necessary teaching links according to the teaching content, the final effect is still somewhat unsatisfactory. The main reason is that theoretical teaching and practical teaching are out of touch and have not achieved organic unity. In teaching activities, theoretical teaching is the basis of practical teaching, and practical teaching is the embodiment of theoretical teaching. The two complement each other and are indispensable. Therefore, it is very important to integrate theory with practice in the course teaching reform.
2 High-frequency electronic circuit course reform measures
2. 1 Optimize the teaching content
According to the characteristics of high-frequency electronic circuit course, we should optimize the teaching content from two aspects: First, make reasonable adjustments to the contents involved in the course. On the one hand, teaching materials need to be adjusted. With the application of more and more advanced technologies in circuit design, traditional electronic circuits have been continuously optimized. Many contents in the previous textbooks are no longer used in real life. Therefore, these contents need to be deleted from the textbook, and only the contents of classical electronic circuits are kept. On the other hand, we should systematically grasp the integrity of the curriculum. In order to further optimize the course of high-frequency electronic circuit, we can divide the course content into three modules, namely, sending equipment, channel transmission and receiving equipment. Each module has its corresponding key and difficult content, and the three modules form a complete curriculum system, which helps students better understand the relationship between chapters, establish system and engineering concepts, and improve their ability to analyze and solve problems.
2.2 Enrich teaching methods
The teaching of high-frequency electronic circuits can adopt many methods, such as questioning teaching method, heuristic teaching method, communicative teaching method, comparative teaching method and inductive teaching method. Each teaching method has its advantages and disadvantages. Teachers should choose the best teaching method according to the actual teaching content, so that teaching activities can get twice the result with half the effort. In addition, with the popularization and development of computer technology and network technology, multimedia teaching methods are also widely used in the teaching of high-frequency electronic circuits. The reasonable collection and application of network resources can help students to further broaden their horizons and master more knowledge of high-frequency electronic circuits. It can be seen that the effective combination of modern teaching methods and traditional teaching methods can further improve the teaching effect.
2.3 Realize the organic combination of theory and practice
Experimental teaching is one of the main contents of high-frequency electronic circuit course teaching, aiming at cultivating students' operational ability and practical ability, and truly realizing the application of what they have learned. In the traditional teaching mode, high-frequency electronic circuits are generally used in experimental teaching. In practice, students only need to complete the two tasks of circuit connection and measuring input and output, which will naturally reduce the learning efficiency. Therefore, in addition to confirmatory experiments, teachers can also add some comprehensive and designed experiments to experimental teaching. For example, the modulation experiment of amplitude modulation signal, the modulation signal is generated by the signal generator. If the modulation signal is turned into an audio signal and the speaker is connected to the output end of the mediation circuit, students can intuitively feel the experimental results through the speaker. This experimental mode not only achieves the goal of organically combining theory with practice, but also has great significance for stimulating students' interest in learning.
3 Conclusion
With the deepening of the concept of quality education, the disadvantages of traditional teaching mode in colleges and universities are becoming more and more obvious, and it is impossible to successfully complete the teaching objectives. Therefore, it is imperative to reform the teaching mode of high-frequency electronic circuit course, which needs the attention of relevant departments of the school. To sum up, under the premise of deepening the concept of quality education, the research and discussion of curriculum teaching reform has become an important task faced by education departments at all levels. Renewing teaching ideas, innovating teaching models and implementing comprehensive reform of teaching models have also become new requirements for education departments in the new era.
This paper only introduces the teaching reform method of high-frequency electronic circuit, and the teaching reform of other courses should also attract the attention of school leaders in order to improve teaching efficiency and quality through scientific and effective teaching reform measures.
