Detailed course introduction:
①c language
C language is a widely used computer language at home and abroad, and it is a programming tool that computer application personnel should master.
C language has rich functions, strong expressive ability, flexible and convenient use, wide application, high efficiency of object program and good portability. It has the characteristics of both high-level languages and low-level languages. Therefore, C language is especially suitable for writing systems.
After the birth of C language, many things originally written in assembly language can now be written in C language.
Novices should not abuse some error-prone details of C prematurely, such as improper use of++and-side effects. When learning programming, you must learn to use it flexibly. Don't learn to use it, but draw inferences from others, so that you can master a new language quickly when you need it later.
② Advanced Mathematics
Advanced mathematics is an important basic subject in universities of science and engineering. As a science, advanced mathematics has its inherent characteristics, namely, high abstraction, strict logic and wide application. Abstract is the most basic and remarkable feature of mathematics-high abstraction and unity, which can profoundly reveal its essential laws and make it more widely used. Strict logic means that in the induction and arrangement of mathematical theory, whether it is concept and expression, or judgment and reasoning, we must use the rules of logic and follow the laws of thinking. Therefore, mathematics is also a way of thinking, and the process of learning mathematics is the process of thinking training. The progress of human society is inseparable from the wide application of mathematics. Especially in modern times, the appearance and popularization of electronic computers have broadened the application field of mathematics. Modern mathematics is becoming a powerful driving force for the development of science and technology, and it has also penetrated into the field of social sciences extensively and deeply. Therefore, it is very important for us to learn advanced mathematics well. However, many students are confused about how to learn this course well. If you want to learn advanced mathematics well, you must at least do the following four things:
First, understand the concept. There are many concepts in mathematics. Concepts reflect the essence of things. Only by figuring out how it is defined and what its essence is can we really understand a concept.
Secondly, master the theorem. Theorem is a correct proposition, which is divided into two parts: condition and conclusion. In addition to mastering its conditions and conclusions, we should also understand its scope of application and be targeted.
Third, do some exercises on the basis of understanding the examples. Especially remind learners that the examples in the textbook are very typical, which is helpful to understand concepts and master theorems. Pay attention to the characteristics and solutions of different examples, and do appropriate exercises on the basis of understanding examples. When writing a topic, you should be good at summing up-not only the methods, but also the mistakes. You will gain something after doing this, so you can draw inferences from others.
Fourth, clear the context. We should have an overall grasp of the knowledge we have learned and summarize the knowledge system in time, which will not only deepen our understanding of knowledge, but also contribute to further study.
③ Signals and systems
Signal and system is the core basic course of communication and electronic information specialty, and its concepts and analysis methods are widely used in communication, automatic control, signal and information processing, circuits and systems.
According to the characteristics of online courses, this course uses multimedia technologies such as pictures, words, sounds, images and animations to make the content vivid and easy to understand. Supported by network technology, this course focuses on students' autonomous learning, combined with teachers' questions and answers, students' discussions and other forms, which makes the course reflect the characteristics of interactivity, openness, autonomy and cooperation.
Conceptually, this course can be divided into two parts: signal decomposition and system analysis, but they are closely related. According to the decomposition of continuous signals into different basic signals, the corresponding analysis methods of linear systems are derived as follows: time domain analysis, frequency domain analysis and complex frequency domain analysis; Discrete signal decomposition and system analysis are similar processes.
This course adopts the layout knowledge of continuous and then discrete, so we can concentrate on learning the content of continuous signal and system analysis first, and then understand the concepts of discrete signal and system analysis through analogy. Combined with two modules, the state analysis method is given, thus the complete concept of signal and system is established.
In addition to the main contents required by the syllabus, this course also gives random signals through linear system analysis, discrete Fourier transform, FFT and other contents to expand the knowledge.
④ Circuit analysis
Circuit analysis is a very important technical basic course for electrical specialty in engineering colleges. This course not only lays the foundation for the following professional courses, but also plays a very important role in developing students' scientific thinking and cultivating their ability to analyze and solve problems. The main contents of this course include: basic concepts and laws of circuits, equivalent transformation of resistance circuits, basic analysis methods and theorems of linear circuits, circuit analysis with ideal operational amplifiers, steady-state analysis of sinusoidal AC circuits, circuits with mutual inductance, three-phase circuits, periodic non-sinusoidal current circuits, two-port networks, time domain analysis of first-order circuits, time domain analysis of second-order circuits, Laplace transform and its application, state variable method, nonlinear resistance circuits, etc.
⑤ Microcomputer principle
The emphasis of microcomputer principle is to introduce instruction system and interface, which is very important to understand the hardware principle of microcomputer. If microcomputer is needed for control and communication, microcomputer principle is a compulsory course. Therefore, the principle of microcomputer is listed as one of the main courses by most majors.
C language is considered as a programming language between high-level language and assembly language, also known as intermediate language. Many operating systems are implemented in C, such as Unix, Linux, minix and so on. Many low-level communication programs, drivers, encryption programs, etc. They are all written in C, the important reason is that C language is very close to assembly language, in other words, C language is close to computer hardware, but at the same time C language programming is much more convenient than assembly, so many people.
Generally speaking, learning the principle of microcomputer does not need the foundation of C language, but really understanding and mastering C language is a necessary foundation. For example, pointer operation in C requires understanding the structure of microcomputer memory.
Unfortunately, at present, most colleges and universities in China take the C test first and then the microcomputer principle. The author thinks that this is really misleading and is not conducive to the cultivation of high-level talents.
In addition, some people think that microcomputer principle, as an important course connecting hardware and software, has not been paid enough attention in colleges and universities, which is not commensurate with the status of this course.
⑥ communication principle
As a practical system, communication is produced to meet the needs of society and individuals, with the purpose of transmitting information (data, voice and images). The development of communication technology, especially in recent 30 years, has formed the main theoretical system of communication principle, namely coding theory, modulation theory and detection theory.
In the course of communication principle, there are many places to use the conclusions or theorems of information theory. Information theory has become a guide for designing communication systems and conducting communication technology research, especially it can tell engineers the performance limit of communication systems.
There is noise in the channel. Noise and interference are inevitable in communication. With the study of noise and interference, stochastic process theory came into being. The analysis of signals is actually the analysis of stochastic processes.
In the field of communication engineering, coding is a technology that can be realized by hardware. There can be many codes in mathematics, which can be mapped to different spaces, but they can only be applied to codes that can be generated and recognized in communication systems. The combination of coding theory and communication forms two directions: source coding and channel coding.
Modulation theory can be divided into linear modulation and nonlinear modulation. The difference between them is that linear modulation does not change the spectral structure of the modulated signal, while nonlinear modulation changes the spectral structure of the modulated signal, which often occupies a wider frequency band, so nonlinear modulation usually has better anti-noise performance than linear modulation.
The receiver separates the modulated signal from the carrier signal, and the process of recovering the modulated signal is called demodulation or detection.
As a course of communication principle, it also includes system contents, mainly including synchronization and channel multiplexing. In digital communication system, only when the received signal is synchronized with the transmitted signal or the same time relationship is established between the signals, the receiving end can demodulate and identify the signal. In order to improve communication efficiency, channel multiplexing is a protocol or specification that arranges many signals to pass through the same channel at the same time, so that the voice, image and other messages of multiple users can be transmitted through the same cable or other channels at the same time.
On the basis of communication principle, it is a professional course to further explain the design of communication system or deepen a certain theory or technology. To design and manufacture communication systems, we need to know the principle, but it is not enough to know the principle. You must also be familiar with hardware (circuit, microwave) and (system and embedded), which is another branch of the professional course plan.
The teaching of communication principle course is mainly divided into two parts: analog communication and digital communication. The emphasis is on modulation, coding and synchronization of digital communication.
With the completion of the teaching content, students are required to complete the necessary exercises. During this period, some verification experiments are provided, and at the same time, SystemView experiment teaching is used to let students know more about the actual work of communication system.
Because it is difficult for students to understand the communication principle, teachers have strengthened the multimedia CAI teaching of this course, and vivid and intuitive illustrations have assisted the teaching. The electronic lesson plan demonstration successfully developed by the course group and the graphic aided teaching based on difficulty simulation are used for teaching. Greatly improved the teaching effect. At the same time, online experimental teaching is being successfully researched and developed, and the use of teaching instruments and the simulation experiments of important experimental instruments are put online to further meet the requirements of teaching informationization and networking. In a word, this course greatly improves students' understanding of the teaching content of this course through theoretical teaching, experimental teaching, curriculum design, CAI courseware, comprehensive design and network teaching.
⑦ Digital circuit
The basic course of digital circuit starts with the most basic gate circuit, and reaches the basic composition and working principle of various common flip-flops, encoders, decoders, memories and sequential circuits. The course patiently explains the basic knowledge and analysis methods of various digital logic circuits, such as what is truth table, what is competitive adventure phenomenon, why computers use binary in various systems, why we often use 16 system, etc., until we can see the world. After reading these, we can understand the origin of digital circuit and find that it is not mysterious, even simpler than analog circuit! With these basic understandings, we can learn and analyze other advanced knowledge of complex digital circuits by ourselves.
⑧ Analog electronic circuit
First, the nature, purpose and task of the course.
Analog electronic circuit is a compulsory technical basic course for electronic information technology major in the Open Institute of Technology of China Central Radio and TV University. This course not only has its own theoretical system, but also is a practical course. The task of this course is to solve the problem of introduction to electronic technology, so that students can master the basic working principle, analysis method and basic skills of analog electronic circuits, and lay a foundation for further study and practical work related to electronic technology in subsequent courses.
Second, the relationship with other courses.
The prerequisite course is the basis of circuit analysis, which lays the necessary foundation for the following courses (such as Modern Electronic Circuit and Technology, Automatic Control Principle, Microcomputer Principle and Application).
Third, the characteristics of the course
1. Knowledge theory is systematic. Learning this course needs to be based on certain basic theories and knowledge, and it is also the basis for learning related follow-up professional courses.
2. The basic theory is relatively mature. Although electronic technology is developing rapidly and new devices and circuits are changing with each passing day, its basic theory has formed a relatively stable system. Limited school teaching can't cover everything. We should focus on learning and master basic concepts, basic analysis and design methods.
3. The practical application is comprehensive. This course is a very practical technical basic course. Many electronic circuits discussed are practical circuits and can be made into practical devices.
Two. What are the courses for information construction and information management?
Specialized courses of information construction and information management;
Basic majors: computer foundation, management, basic mathematics majors such as calculus, advanced algebra, probability theory and mathematical statistics, discrete mathematics, etc.
Specialized subjects: data structure, introduction to database, introduction to information systems, information management and theory, information construction, information ethics, circuits, etc.
Informatization management is a process of promoting industrialization with informatization and realizing the modernization of enterprise management. It is a process of integrating modern information technology with advanced management concepts, transforming enterprise production mode, management mode, business process, traditional management mode and organization mode, re-integrating enterprise internal and external resources, improving enterprise efficiency and effectiveness, and enhancing enterprise competitiveness.
Three. What is the information-based classroom teaching like?
Informatization teaching is a bilateral activity between educators and learners under the information environment with the help of modern educational media, educational information resources and educational technology. Its characteristics are as follows
Supported by information technology
Guided by modern education and teaching theory
Attach importance to the construction of new teaching mode.
The teaching content is more contemporary and rich.
Teaching is more suitable for students' learning needs and characteristics. Informatization teaching is not only the change of teaching media and means based on traditional teaching, but also a series of reforms and changes of the whole teaching system based on modern information technology.
Information-based teaching design was put forward by Professor Li Touhou of Shanghai Normal University, that is, using systematic methods, taking learning as the center, making full use of modern information technology and information resources, and scientifically arranging all links and elements in the teaching process to optimize the teaching process. The application of information technology to construct information environment, obtain and utilize information resources, support students' independent inquiry learning, cultivate students' information literacy, improve students' interest in learning, and thus optimize teaching effect.
The traditional classroom teaching mode is teacher-centered, book-centered and classroom-centered. The traditional classroom teaching mode often forms a situation in which teachers instill and students passively accept. It is not difficult to see that the defects of traditional teaching mode are very obvious. The key point is that students, as cognitive subjects, are always in the position of passively accepting knowledge in the whole teaching process, and their learning initiative is ignored or even suppressed. Obviously, this does not meet the requirements of modern society for talent training, and this model can not bear the heavy responsibility of cultivating high-quality creative talents. Therefore, it is imperative to change the traditional teaching mode and create an efficient classroom mode that meets the requirements of the new curriculum reform.
Ⅳ What are information-based teaching resources and what are their functions?
Teaching practice shows that the effective use of digital teaching resources is of great significance to the shaping of students' learning ability, problem consciousness and even skepticism. It is an excellent way to cultivate students' autonomous learning ability and entrepreneurial ability by truly using digital teaching resources to stimulate students' learning interest and discovery ability. In the digital age, the advantages of the younger generation usually exceed those of the elderly. This sense of superiority, which is not caused by individual factors, is increasingly recognized, which is also one of the most important gains made by mankind in the digital revolution. The DIY learning concept naturally generated by digital culture has become the symbolic cultural symbol of the network. This cultural concept often cultivates a spirit of interaction, which can help children grow up, cultivate their own values, and train their ability to judge, analyze, evaluate, criticize and help others. In this case, teachers should actively and timely guide students to develop and use digital teaching resources in teaching, so as to cultivate students' ability of discovery, thinking, analysis and judgment. Students can choose and sort out relevant teaching materials and academic information according to their existing knowledge background and thinking structure and their academic needs, build their own knowledge system and get their own opinions.
By contacting with digital teaching resources, students can not only acquire the ability to construct knowledge, but also cultivate information literacy. The ability to construct knowledge is mainly the acquisition of autonomous learning ability. Through the practice of selecting and utilizing digital teaching resources, students' learning has changed from one-way teaching mode of teachers to constructive and exploratory learning, from passive learning to active learning, and from teachers to students to create their own knowledge. Research shows that in the digital age and information society, the important prerequisite for students to realize autonomous learning depends on what kind of information literacy they have. Allowing students to directly use digital teaching resources is undoubtedly a great opportunity to exercise and improve students' information literacy, and it is also one of the best ways and means to test students' learning ability and learning gains.
Compared with students, teachers feel not only convenience but also challenge in the face of digital teaching resources.
First of all, in the digital age, we must have a new understanding and orientation of teachers' role concept. In the traditional teaching mode, limited by conditions, teaching is mostly teacher-centered, and the teaching structure is linear, with teachers' one-way communication as the mainstay. In most cases, students are passive recipients, and the autonomy of learning is difficult to reflect. Teachers' professional background, knowledge orientation and personal preference all have a decisive influence on the teaching content, so in a sense, teachers are in a central and authoritative position in teaching and hold the main right to speak. It should be said that in the era when information technology and digital technology are underdeveloped, the traditional one-way communication (also known as broadcasting) teaching mode is almost the best choice. It has played and is still playing an important role in human education and the history of civilization. However, with the advent of the digital information age, the previous structural model of teaching and learning has been greatly challenged, and the channels and media for learning knowledge are no longer single. Not only the paper media culture, but also the electronic media, especially all kinds of digital knowledge and resources on the network, have challenged the central position of teachers. Everyone is equal before the network and information, and teachers and students have the same information conditions and face the same information resources, which undoubtedly puts forward new topics for teachers. Teachers should not only avoid and turn a blind eye to the advantages of students using digital teaching resources, but also encourage and inspire them. "Disciples don't have to be inferior to teachers", and the essence of education lies in transcendence, which is the essential purpose and appeal of education.
Ⅳ What are the courses of enterprise information management?
Overview of informatization, financial management, customer relationship management, supply chain management, human resource management, etc.
ⅵ How to Really Realize Informationization Teaching
To promote deep integration as the core, explore the means of educational informatization ",and" vigorously promote and deepen the application, and expand the coverage of quality education resources ". Before teaching, we must make a good learning guidance plan, which must reflect the detailed process of "guiding, interacting, encouraging and evaluating" students. In this context, advanced teaching models such as flip classroom and large-scale open online courses have been applied in primary and secondary schools.
Students first watch the teaching courseware recorded by the teacher; On the day of class, students ask questions directly on the basis of preview, and the teacher makes appropriate explanations, answers, supplements or extensions. In this mode, students actively acquire knowledge, find problems and solve problems with teachers and classmates in the form of inquiry, which greatly improves learning efficiency and learning effect.
