What is the medium used?

Question 1: What is the media? 1. Media is art The word "media" is frequently used on many occasions. When people use this word in different environments, "media" will be given different meanings. It is very unwise to make a unified definition of the meaning of "media" in various situations. The famous scholar McLuhan said that "media is information", and he defined it from the perspective of users of media content. If we look at it from another angle, not from the audience's point of view, but from the communicator's point of view, we can define the media as follows: "Media is art", and the definition of art, like that of media, is a rich and controversial focus. The author once expressed the following views in his paper: "Art is a symbolic information transmission process." Art becomes art because it uses a unique symbol system. Art has a symbol system of art, music has a symbol system of music, and movies have a symbol system of film and television. At the same time, art is a process of information dissemination, in which artists encode information and appreciators decode it. From the perspective of art, "communication is an art", and from the perspective of communication, "art is a kind of communication". Professor Hu Zhifeng of China Communication University once put forward the concept of "art communication". Media not only includes many artistic styles in art, for example, newspapers include literary styles, radio includes musical styles, and television includes artistic and musical styles. The media itself is an artistic style, an independent art with a unique symbol system. The symbol system of media includes ideology, media economy, social effect and media ethics. Ideology is inevitable in the symbol system of the media, which is the superstructure of the economic base and is bound by the economic and political systems. Media has been industrialized in the wave of globalization, and culture has been used in business, and culture has begun to make a direct contribution to economic development. To survive, the media must consider economic issues. Social effects also play a role in the media economy to some extent, such as the level of ratings. However, social effect not only refers to people's behavior of receiving information, but also includes psychological effect and action effect after using media. The "reputation" that the media is very concerned about is often directly related to this. Media ethics is called "moral judgment" to some extent. When news events involve values, the media are often good at giving their own judgments. The above four symbols are artistically implied in the information spread by the media. The audience not only accepts the information itself, but also exerts a noticeable influence on the audience. The symbol system of media is the essence of media becoming art. They take news material as the carrier and transmit information outside the news text. This information is usually deep and is the "signified" contained in the symbol with "signifier". The media literacy of the audience determines the decoding process of information. The higher the media literacy, the more media art symbols are solved. Just as ordinary audiences and art critics appreciate a painting at the same time, art critics can often interpret more hidden information. The author believes that the improvement of media literacy should first understand the artistic symbol system of the media and have a clear understanding of how ideology, media economy, social effects and media ethics play a role in the communication process. Secondly, we should be an active audience, actively use the media, and effectively use the media to extend our senses, instead of passively accepting the bombardment of various media information. In the post-modern context, under the impact of foreign culture in the wave of globalization, when new media technologies are full of tricks, it is more difficult for people to find their own direction and are easily disturbed by bad information, so it is necessary to improve media literacy. Artistic interpretation of the media can effectively improve their insight into the media, become an active audience, and feed back our information to the communicators through the media to complete the "two-way flow" in the sense of communication. Of course, the improvement of media literacy depends on the individual cultural quality and cultural environment of the audience, and cultural research also has a unique position in media theory. Second, media and cultural media can be classified into the category of culture in the past social classification, and culture is often used side by side with politics and economy. What is culture? The definition of culture is also rich and colorful. In our discussion of the media, culture can be defined as: "the way of thinking and behavior with communication characteristics formed by people in social life." For example, China has tea culture. After entering the door, the host is polite and the guests think so, so this way of serving tea spreads a specific message. Culture has the characteristics of communication.

Question 2: I am in a hurry. What is the medium of the hard disk video recorder? Hard disk, of course.

Question 3: What does machine media system mean? Hart divided the media in history into three categories:

1. That is, the media that transmit information face to face, such as spoken language and nonverbal symbols such as expressions, movements and eyes. , is a media system executed by human senses or organs themselves. Neither the sender nor the receiver need to use the machine.

2. Copy the media system. Including painting, writing, printing and photography. The sender needs to use the machine.

3. Machine media system. Including telecommunications, telephone, records, movies, radio, television and computer communications. Both sender and receiver need to use the machine.

These three types of media appear in order. It is a process in which human media means are becoming more and more abundant, the information function of human body is expanding outward day by day, and the externalized information system is gradually gaining relative independence.

Question 4: What is the role of the media? First of all, multimedia-assisted teaching methods cannot exclude or replace the traditional classroom teaching mode.

Traditional teaching mode is an effective teaching mode summarized by educators through long-term practice and research. The current teaching mode can not be separated from the traditional teaching methods, and multimedia teaching methods can only play an auxiliary role, but can not completely replace the traditional teaching mode. Some teachers think that multimedia classroom teaching has advantages that traditional teaching mode does not have. Every class must be multimedia, especially open class or demonstration class. It seems that without multimedia, it is not a good class. This understanding overemphasizes the advantages of multimedia teaching, but ignores the students' dominant position, the leading role of teachers and the emotional communication between teachers and students in the classroom, which weakens teachers' teaching art and improvisation ability, which is not in line with students' cognitive law. If we blindly pursue the "luxury" of classroom teaching process, pay attention to sound, video, animation and projection, and pursue the "large capacity" of knowledge transfer, we will eventually either distract students' attention or make them lose sight of one thing and reduce classroom efficiency. Every teacher's specific teaching language, teaching attitude, writing on the blackboard and adaptability are the greatest wealth. Only by organically combining traditional teaching methods, teachers' personal characteristics and multimedia-assisted teaching can the effect of multimedia classroom teaching be truly brought into play.

Second, multimedia-assisted classroom teaching must help to break through the teaching difficulties.

The use of multimedia technology in classroom teaching must help to break through the difficulties of teaching content, otherwise it is unnecessary to use multimedia technology. It is the research direction of multimedia-assisted teaching to show abstract concepts and theories that are difficult to be directly expressed in words in an intuitive and acceptable form, or to show toxic and dangerous experiments in classroom demonstration experiments in the form of playing videos, or to show the microstructure of substances or the motion state of microscopic particles in the form of animation. Multimedia classroom teaching must not remain superficial, computer screen can not be used instead of blackboard writing, and video can not be used instead of all classroom demonstration experiments. Like this class, it is more important for teachers to give students demonstration experiments, because only in this way can students see the reaction phenomenon intuitively, be more convincing and leave a deeper impression on them.

Third, the production of multimedia integrable ware must be scientific.

Science is the first and most important nature in natural science. Without science, the foundation of natural science will be lost. Therefore, when designing integrable ware, we must be careful not to make scientific mistakes, otherwise it will not only help teaching, but also bring greater negative impact to students.

Fourth, correctly handle the relationship between the various elements in the teaching process.

The process of multimedia classroom teaching mainly includes four elements: teachers, students, teaching materials and media, which are interrelated and restricted to form an organic whole. In order to achieve good teaching effect, we must deal with the relationship between the four elements. According to Piaget's constructivist learning theory, teachers are organizers and instructors in the teaching process, helpers and promoters in the construction of knowledge meaning, rather than knowledge agitators in active teaching; Students are the active constructors of knowledge meaning, not the passive recipients of the outside world and the objects of knowledge indoctrination; The knowledge provided in textbooks is the object of students' active construction, not the content instilled by teachers; Media is a cognitive tool for students to create learning situations, actively study, cooperate and explore, and complete the construction of knowledge meaning, rather than a means and method for teachers to instill in students. It can be seen that multimedia-assisted classroom teaching cannot simply replace all kinds of multimedia teaching, and it is still necessary to give full play to the leading role of all kinds of multimedia and the main role of students, and at the same time highlight the auxiliary function of multimedia teaching.

Fifth, the compilation of multimedia courseware should not deliberately pursue three-dimensional animation.

Multimedia classroom-aided teaching can only serve the purpose of classroom teaching, and cannot deliberately pursue the demonstration of three-dimensional animation. At present, it is generally believed that a multimedia teaching courseware must have three-dimensional animation. If there is no demonstration of three-dimensional animation in the courseware, the grade of the courseware is not high. This is a wrong understanding, because multimedia courseware only serves for classroom teaching, and completing the task of classroom teaching should be the first element. If you deliberately pursue the demonstration of three-dimensional animation, it will be a bit wasteful. Three-dimensional animation cannot replace the real model.

Therefore, multimedia-assisted classroom teaching is the supplement and development of traditional classroom teaching mode, and the application of multimedia classroom teaching is also the development of classroom teaching. & gt

Question 5: What does the media mean? Is it similar to the media? Media is a basic title, which refers to the intermediary between information source and information receiver. It can be a person, an institution, or an object that can transmit information, such as a small note:)

Besides the significance of the media, it is more important to emphasize its materiality. For example, television, radio, newspapers and the Internet are the four major media today, and some people understand it as a comprehensive application of various modes of communication such as multimedia.

In fact, media is the abbreviation of media, but now it has its specific meaning, which represents the highest realm of communication, mass communication. They have turned some channels of obtaining information in our lives into media organizations, such as newspapers and radio stations.

Question 6: What media is used for outdoor pull rod audio? There are only two kinds of media, one is wired connection (or built-in) and the other is wireless connection.

Wired connection means using external devices to play sound sources through wires or built-in sound systems (including CD, DVD, computer, USB flash drive reader, etc.). ), and then the audio is amplified by the power amplifier to make a sound.

The wireless connection is realized by a set of wireless transmitters. The transmitter converts and compresses the signal and then sends it to the receiver by radio. The receiver converts it into an electrical signal through decompression, and then amplifies it through an amplifier to push the sound to make a sound.

Question 8: What is the media? What is multimedia? What are its main features? 1. What is multimedia technology? Multimedia technology refers to the information technology and method that takes the computer as the core, interactively and comprehensively processes various media information such as text, graphics, images, videos, sports videos, animations, etc., and effectively controls them through the computer, so that these information can be logically connected to show richer and more complex information. Second, what are the characteristics of multimedia technology? Four characteristics of multimedia technology: 1. The integration of integrated multimedia technology is mainly manifested in two aspects, that is, the integration of various information media and the integration of equipment dealing with these media. 2. The controllability of multimedia technology is also reflected in its friendly interface technology, which can fully enhance and improve the function of man-machine interface, make it more vivid, intuitive and friendly, and express more information. 3. Interaction is one of the characteristics of multimedia technology. Interactivity means that users can interact with various information media of computers, thus providing users with a means to control and use information more effectively. Because interaction can increase the attention and understanding of information and prolong the time of information retention, with the help of interaction, people do not passively accept words, sounds, graphics, images, moving videos and animations, but actively search, ask questions and answer. For example, CD-ROM can easily store dozens of encyclopedias on a CD-ROM, and readers can query and browse the information in the CD-ROM at any time and choose the content of interest to read. This feature is beyond the reach of ordinary books, audio tapes and video tapes, which makes optical discs widely used in the field of education. 4. Digitalization From the point of view of technical realization, multimedia technology must digitize all kinds of media information, so as to integrate all kinds of information on a unified multimedia computer platform and solve the problems of diverse and different multimedia data types, which is also the only feasible method for multimedia technology. Therefore, digitalization is the basis of the development of multimedia technology.

Question 9: What are the motivations for media use in social situations? Different social occasions

Triggered different social needs.

So as to generate different media pair selection.
