Research and Application of "Electrical and Electronic Technology" Networked Teaching System

"Teaching and Research of Electrical and Electronic Technology" Research and Application of Networked Teaching System Xu Shuhua's electrical and electronic technology courses are highly practical, and most science and engineering majors must provide a basic course. Through the study of this course, learners can obtain the basic theory, basic knowledge and basic skills of electrical engineering and electronic technology. The course involves almost all fields of electrical and electronic disciplines, with many courses, large amounts of information, and broad knowledge. Especially in the information age of the 21st century, science and technology in different fields will be creatively integrated. Each science and technology major will use the intersection and integration with the electrical and electronic disciplines to promote the development of this discipline and open up new discipline areas. The course requires appropriate selection of basic content, strong foundation, clear concepts, and emphasis, embodying new technologies, emphasizing practicality and practicability. With the rapid development of electrical and electronic disciplines, teaching and experimental content needs to be constantly supplemented and updated. On the basis of traditional theoretical practice teaching, some new devices and new technologies in development must be reflected in the classroom and experiments at any time. This puts forward higher requirements for the distance teaching of electrical and electronic technology, and makes the adult education of this course more difficult.

The development of "Electronics and Electronic Technology" networked teaching system is a good opportunity to solve this problem.

"Electrical and Electronic Technology" networked teaching system is a virtual multifunctional teaching environment based on network technology. The system also includes supporting teaching materials, experimental instruction books and other learning materials.

Course introduction: including course introduction, syllabus, teaching requirements and learning progress. To enable learners to clarify the basic requirements and teaching process of the course.

Multimedia classroom: including multimedia chapters of each chapter, chapter points), teaching points of each chapter, analysis of key and difficult points, example questions, summary and materials, etc. Learners can get a vivid and vivid analysis of all the content of the course from the multimedia classroom. They can learn step by step according to the requirements, or they can choose and repeat a certain part of the content arbitrarily according to the needs of the individual.

The above three parts belong to the shared space. )) Virtual laboratory: a simulation experiment platform composed of EDA technology and EWB software established on the Internet. With this platform, learners can carry out various types of experiments of various electrical and electronic technologies such as verification, testing, error correction, design, and innovation. They can also simulate in real time. During the simulation process, learners can change at any time Circuit structure, change circuit parameters, measure data, observe waveforms until the circuit is optimal. The experimental results can be submitted to the teacher's judgment at any time, and can also be exported to common printed circuit board typesetting software to automatically discharge printed circuit board drawings to complete the actual circuit production or product development.

/) Exercise library: The exercise library organizes many practice questions according to the new electrical and electronic technology teaching system, on the basis of its large modules, and arranges them according to the textbook chapters. Question types include concept questions, analytical calculation questions and comprehensive design questions. The content goes from easy to difficult, step by step. The difference between the system problem bank and the conventional problem bank is that it also includes problem solutions, answers, and interactive self-test functions, which are convenient for learners to practice. After the learner enters the question bank, they can browse all the exercises by chapter and by the type of exercise, choose what suits their needs, and submit the system after the calculation is completed. The system immediately gives the score and gives the correct answer in error; the exercise bank facilitates the learner Consolidate the review of what you have learned.

0) Question answering classroom: The learner enters the question answering classroom and can perform real-time and interactive question answering with the teacher, and can also provide automatic question answering service, or discuss through e-mail. As long as one teacher enters the Q & A classroom, he can answer all the questions raised by students in different places. For the questions that teachers cannot answer at once, they can be answered online after collective discussion. Some typical problems are sorted and stored on the Internet for the computer to answer questions automatically.

7) System examination room: The system examination room is used for self-examination and final examination. To enter the examination room during non-examination time, you can enter the self-examination practice page, and select a chapter according to your learning situation. According to the degree of difficulty, the system uses the random questioning method to automatically generate questions. When the learner is doing the question, the system can automatically time it. After finishing the question or when the time is up, submit the system to automatically judge the paper, get the score immediately, display the result, but do not write it into the database. Students need to enter the student ID and password before entering the normal exam. After submitting the system to confirm, they are allowed to participate in the online exam. The test questions are designed by the teacher in advance to create the question parameters, such as the amount, type, difficulty level, time, etc. of each knowledge point After the students enter the exam, the system randomly selects questions from the question bank according to the preset parameters, so that each student's test questions are different. During the process of making a question, the system can automatically time and display the countdown time. After finishing the question or when the time is up, submit the system to automatically judge the paper, get the score immediately, display the result, and write the score into the database, which is convenient for teachers to print and process statistical reports. The system test room provides learners with a platform for testing learning effects.

1) Evaluation of teaching quality: Through various questioning and feedback surveys, the networked teaching system of electrical and electronic technology is evaluated, and if deficiencies are found, the teaching strategies are adjusted in time to add new content. Students can submit their opinions and suggestions to the system through this webpage at any time, so as to continuously improve and perfect the system.

The above five parts are interactive spaces.

The "Electrical and Electronic Technology" networked teaching system integrates classroom teaching, experimental teaching, counseling and answering questions, usual practice exercises and final theoretical exams into one system. Most modules are interactive. On the premise of fully demonstrating the advantages of networked teaching, the system maintains the mutual relationship between the teaching links of the traditional teaching model and maintains the advantage of easy communication between teachers and learners. It not only displays the course content on the Internet through colorful multimedia courseware, but also moves the laboratory to the network, so that the learner can complete the course learning on the Internet, at the same time, through the corresponding experiments to test, and even the product circuit design, Development. The entire experimental process, including the experimental circuit and simulation results, can be provided to teachers immediately. Teachers can also guide learners online. "Electrical and Electronic Technology" networked teaching system is an attempt to online teaching of practical science and engineering courses.

The development of the "Electrical and Electronic Technology" networked teaching system can further update teachers' concepts in the process of educational information networking, give full play to the role of teachers as knowledge spreaders, organizers and managers of the teaching process, improve teacher retrieval The ability to process information such as screening, identifying, using, expressing and outputting information. And further reform the teaching content, publishing teaching materials suitable for network teaching. The electrician and electronic technology networked teaching system and various supporting learning materials are presented to learners at the same time. To provide learners with a brand-new, advanced and practical learning environment, which is more conducive to learners' online learning.
