◇ Teaching content system structure, organization and purpose
Combined with the rapid development of electronic materials and related fields at home and abroad in recent years, the inherent characteristics of electronic science and technology (solid electronics) and the characteristics of this course, and considering the important influence of this major in our school, we mainly grasp the following three principles when designing the course system structure, organization method and teaching content:
① The combination of dielectric semiconductors is the future development direction and training characteristics of this major;
② Use the combination of materials, devices and systems to broaden students' knowledge structure;
③ Take material-device-integration-packaging-design as a social demand.
At the same time, in the construction of teaching materials:
In the form of circular rolling, the evaluation and transformation will be carried out every three years, and the construction idea of one procurement, one preparation and one planning will be adopted.
The teaching content of this course is divided into nine chapters: introduction to electronic materials, conductive materials, resistive materials, superconducting materials, semiconductor materials, dielectric materials, optoelectronic materials, magnetic materials and sensitive electronic materials. This paper systematically introduces the manufacturing methods, structural characteristics, electromagnetic properties, component design, application development and other basic knowledge of major electronic materials involved in the electronic information industry. According to the characteristics and requirements of this major, the sixth and eighth chapters are the focus, the second and third chapters are self-study, and other chapters are generally explanations.
Design concept of practical teaching
The design concept of practical teaching takes the comprehensive cultivation of knowledge, ability and quality as the requirement, and aims at improving students' "independent thinking ability", "autonomous learning ability", "ability to analyze and solve problems", and enhancing students' "professional consciousness" and "innovative consciousness".
Under the guidance of the established practical teaching design concept, the teaching content is carefully refined. The characteristics of experimental teaching content mainly focus on:
(1) integrates theory with practice, and the experimental content is novel and applied. Experimental teaching especially emphasizes the combination of theoretical teaching and experimental links. The theoretical teaching content of 4 hours focuses on the relationship between the preparation process, microstructure and performance evaluation of electronic materials and component manufacturing, analyzes the common methods and key steps involved in the preparation process of electronic materials, and compares the adaptability of these methods. The teaching content comes from scientific research projects, which is innovative and academic. The experimental projects carried out by students are all derived from the research contents of scientific research projects, with novel experimental contents and advanced technical means, thus ensuring the academic and technological advancement of experimental contents and enhancing students' awareness of engaging in scientific research.
(2) The whole teaching process from material technology, test analysis and performance characterization to parts manufacturing. The experimental teaching content of this course is developed from three aspects: preparation technology of electronic materials, microstructure and performance characterization, structural design and trial production of components. Through process experiments, students are familiar with the preparation methods, processes and key processes of electronic materials, understand and master the influence of key process parameters on the structure and performance of electronic materials, and fully understand the importance of preparation technology and process control of electronic materials; By analyzing the microstructure and electromagnetic characteristics of samples made by students in the process, students can master the commonly used evaluation methods of physical and chemical characteristics of electronic materials and the characterization techniques of dielectric and magnetoelectric parameters, and cultivate their awareness of electronic materials research from three aspects: adjusting material preparation technology, controlling microstructure and phase composition, and optimizing electromagnetic characteristics of electronic materials. According to the specific functions shown by the physical and chemical properties of different material samples, we try to make components with different functions, cultivate students' ability to apply the functional characteristics of electronic materials, and enable students to acquire certain ability of component design and development.
The experimental teaching of this course emphasizes the cultivation and improvement of students' scientific research and development quality and production practice ability. The characteristics of experimental teaching methods are mainly manifested in the following two aspects:
(1) experimental teaching and practice are combined with the scientific research and development of the school and the industrial production of the enterprise. The understanding of electronic materials and device manufacturing broadens the industrial vision and enables students to fully understand the position of this discipline in the electronic information industry. In addition to using the school's scientific research platform to carry out experimental teaching, experimental teaching also combines the cooperative enterprises transformed from scientific research achievements of this discipline to carry out in-depth practical teaching, thus effectively mobilizing students' experimental enthusiasm and stimulating students' experimental interest.
(2) The interactive experimental teaching method combining group experiment with concentrated discussion is adopted. On the basis of the tutor's introduction of the experiment to be carried out, the students will conduct the experiment in groups. After completing this experiment or the intermission of experimental work (such as waiting for the equipment to heat up), the experimental principles, experimental techniques and methods, experimental phenomena and results, as well as the scientific research and industrial application involved in this experiment are discussed, so that students can deepen their understanding of the basic principles and knowledge from the experiment as much as possible, fully understand the basic experimental techniques and methods, and fully understand the experimental ideas and work spirit of scientific research.
To sum up, correct teaching guiding ideology, novel and practical teaching content and advanced teaching means and methods ensure good teaching effect. (1) Strengthen the course of process experiment to improve students' practical ability. After nearly five years of practice, it has been proved that students' practical ability has been generally improved, which has been greatly welcomed by enterprises. My major has maintained 96% employment rate for three consecutive years, benefiting from the reform of curriculum and practice. (2) Inter-school cooperation to promote curriculum reform through communication. Our school's curriculum reform is coordinated with peer schools such as Tianjin University, Xi University of Electronic Science and Technology, Huazhong University of Science and Technology and Shanghai Jiaotong University, while maintaining their own characteristics. For example, the University of Electronic Science and Technology of China has maintained its influence advantages in the field of electronic ceramics and magnetic materials at home and abroad for 45 years, and these two aspects are the mainstream in the course embodiment, supplemented by other aspects, to promote inter-school cooperation, maintain characteristics and develop together.

teaching method
According to the characteristics and basic teaching rules of electronic materials, through the continuous exploration and reform of this course group for many years, the theoretical teaching, practical experimental teaching and assessment methods of this course are effective and the course characteristics are obvious. In teaching practice, we mainly use the methods of "combining traditional teaching methods with modern educational technology", "combining emphasis with generality in classroom teaching" and "combining theoretical teaching with experimental teaching". Teaching methods such as "combination of on-campus practice teaching and off-campus practice base", "combination of counseling and answering questions and extracurricular activities" and "combination of theoretical examination and practical skills" have improved students' independent thinking ability, "autonomous learning ability" and "ability to analyze and solve problems", enhanced students' professional awareness and "innovative awareness", and enabled graduates to have strong research and development capabilities in electronic materials and components and related fields.
teaching means
1. Classroom teaching means-the combination of multimedia teaching and traditional blackboard writing teaching;
Traditional teaching method is a teaching method in which teachers use blackboards, chalk and lesson plans in ordinary classrooms, while multimedia-assisted teaching method is a new teaching method in which teachers use projectors, computers, networks and other modern media to teach in multimedia classrooms. In the classroom teaching of this course, we carefully designed the Powerpoint multimedia handout of this course. The handout is illustrated with pictures and texts, entertaining and entertaining, which makes abstract questions vivid, helps to cultivate and stimulate students' interest in learning, and facilitates students' understanding and application of knowledge points. Through the use of multimedia courseware, it can also save the time of traditional blackboard writing, increase the amount of information in classroom teaching and improve learning efficiency. Secondly, the proper combination of blackboard writing and the calculation process on the blackboard can not only make students feel bored, but also keep their thinking synchronized with the teacher.
2. Modern teaching methods-online teaching:
This course also makes full use of modern teaching methods. Rich network teaching resources provide convenience for students' self-study and review, and also greatly enhance the interaction between teachers and students, breaking the relative isolation between teachers and students. This kind of interaction is almost real-time and can be realized through various channels, such as e-mail, BBS, online chat and so on. The syllabus introduces the teaching purpose and requirements of this course; Electronic courseware is a PowerPoint multimedia courseware for classroom lectures. It is made into the form of web pages, which is convenient for students to preview and review what they can't understand and master in class. The electronic teaching plan (Word document) points out the key points and difficulties of each chapter in the course and explains them. Through online practice, students can get timely feedback and targeted diagnosis about their learning process, so that students can adjust their learning in time; The combination of network with multimedia technology and virtual reality technology can realize virtual library, virtual laboratory and virtual classroom, provide students with multi-level and all-round learning resources, and guide students to change from passive learning to active learning. Ask online questions and answer online, and you can answer students' questions at any time; Online discussion is a free forum for students and teachers to participate, and students can also exchange experiences with each other.
3. Auxiliary teaching means-the combination of experimental teaching and theoretical teaching
On the basis of theoretical teaching, we also carefully designed related experiments, such as the observation of ceramic microstructure, the resistance-temperature characteristics of PTC thermistor, the volt-ampere characteristics of PTC thermistor and so on. Through these experiments, students can fully grasp the structure, composition, impurities, defects of electronic ceramics and the influence of technological process on the structure, performance and electronic technology of electronic ceramics, and strengthen the understanding of classroom teaching content.
