Question 5: What is requirements analysis for multimedia works? What are the main aspects? Multimedia technology is not a simple composite of various information media, it is a text (Text), graphics (Graphics), images (Images), animation (Animation) and sound (Sound) and other forms of information combined together, and through the computer for integrated processing and control, can support the completion of a series of interactive operations of information technology. The development of multimedia technology has changed the use of computers in the field, so that the computer from the office, laboratory in the specialties into the information society of the ordinary tools, widely used in industrial production and management, school education, public **** information consulting, commercial advertising, military command and training, and even family life and entertainment and other fields. Multimedia technology has the following main features: (1) integration of information can be multi-channel unified access, storage, organization and synthesis. (2) control Multimedia technology is a computer-centered, integrated processing and control of multimedia information, and according to the requirements of a variety of media forms to show, at the same time act on a variety of human senses. (3) Interactivity Interactivity is a multimedia application is different from the traditional information exchange media, one of the main features. Traditional information exchange media can only one-way, passive dissemination of information, and multimedia technology can realize the active selection and control of information. (4) non-linear multimedia technology will change the non-linear characteristics of people's traditional sequential reading and writing mode. In the past, people read and write the way most of the chapters, sections, pages of the framework, step-by-step access to knowledge, and multimedia technology will be the use of hypertext links (Hyper Text Link) method, the content of a more flexible, more changeable way of presenting to the reader. (5) Real-time When the user gives an operation command, the corresponding multimedia information can be controlled in real time. (6) Convenience of information use Users can use the information according to their own needs, interests, task requirements, preferences and cognitive characteristics, and take any graphic, text, sound and other forms of information expression. (7) Dynamics of the information structure "multimedia is a book that can never be finished", the user can re-organize the information in accordance with their own purposes and cognitive characteristics, add, delete or modify the nodes, re-establish the chain 1.2 File Representing a variety of media coded data in the computer are stored in the form of a file, is the binary data *** . The naming of the file follows specific rules, generally consists of the main name and extension of the two parts, the main name and the extension of the name between the use of . Separated from the extension, the extension is used to indicate the type of file format. 1.3 types and characteristics of multimedia information (1) Text Text is the text and a variety of special symbols to express the form of information, it is the most used in real life, a way to store and transfer information. Text to express information to the full imagination of people, it is mainly used for the descriptive representation of knowledge, such as the elaboration of concepts, definitions, principles and issues, as well as display titles, menus and other content. (2) Image Image is one of the most important forms of information expression in multimedia software, which is the key factor to determine the visual effect of a multimedia software. (3) Animation Animation is the use of human visual ephemeral characteristics, rapid playback of a series of continuous movement changes in the graphic image, but also includes the picture of the zoom, rotate, transform, fade in and out and other special effects. Animation can visualize the abstract content and make the teaching content which is difficult to understand become vivid and interesting. Reasonable use of animation can achieve twice the result with half the effort. (4) sound Sound is one of the most convenient and familiar ways that people use to transmit information and communicate their feelings. In multimedia courseware, according to its form of expression, sound can be divided into three categories: explanation, music and effect. (5) Video images Video images have a chronological and rich information content, often used to explain the development of things. Video is very similar to what we know about movies and television, sound and color, in multimedia plays an important role. 1.4 Multimedia computer system Multimedia computer system is not a single technology, but a variety of information technology integration, is a variety of technologies applied to a computer system, to achieve information input, information processing, information output and other functions. A complete multimedia computer system consists of multimedia computer hardware and multimedia computer software composed of two parts. First, the multimedia computer hardware The main hardware of the multimedia computer in addition to conventional hardware such as the host, floppy disk drives, hard disk drives, monitors, network cards, but also audio information processing hardware, video information processing hardware and optical ...... >>
Question 6: How to evaluate a multimedia work Criterion 1:
I. Principles of pedagogical
1, describing the scientific nature of the concepts: the courseware is suitable for the material, the content of the scientific, correct and standardized.
2, the accuracy of the expression of the problem: all expressions in the courseware should be accurate.
3, the correctness of the cited information: the correct information cited in the courseware.
4. Reasonableness of cognitive logic: the presentation of the courseware is in line with modern educational concepts. It should be conducive to both the teacher's teaching and the students' learning. The teaching of courseware is mainly expressed in the courseware teaching objectives, content selection and organization of performance strategies.
Second, the principle of control
Classroom teaching time is limited, teachers and students can not make the valuable time wasted on the debugging and control of courseware, but also can not turn the courseware into a movie film, a put in the end. Therefore, the operation of the courseware should be simple, flexible, reliable, easy for teachers and students to control, so that teachers and students can be used flexibly after simple training.
Third, the principle of simplicity
The main channel for students to receive information is visual ***, so the projected picture should be in line with the visual psychology of students. The layout of the screen to highlight the key points, to avoid or reduce the attention of students caused by the interference of unhelpful information. Pay attention to the color contrast between the animal and the still life, the color contrast between the foreground and the background, the thickness of the lines, the size of the characters to ensure that the whole class of students can fully perceive the object. It is best to use fade-in and fade-out for content entry and exit, and avoid fancy movements.
Nail four, the principle of scientific
Scientific is undoubtedly one of the important indicators of the evaluation of courseware, to do a specific analysis of scientific issues. The basic requirement of scientificity is that there is no intellectual error, the simulation conforms to the physical principles. Secondary school physics CAI in our country although there have been twenty years of history, but is still in the exploration of the wandering stage, the preparation of courseware is still in the immature period, if a one-sided emphasis on scientific, will bind people's hands and feet, is not conducive to the vast number of teachers into the ranks of the courseware preparers. So it is appropriate to be coarse rather than fine in the judgment of scientificity.
Fifth, the principle of art
1, picture art: the picture production should have a high degree of artistry, the overall standard is relatively uniform.
2, language and text: the language and text displayed in the courseware should be standardized, concise and clear.
3, sound effects: the sound is clear, no noise, the courseware has a role in enrichment. If a courseware display not only achieve good teaching results, but also pleasing to the eye, so that people get the enjoyment of beauty, it is said that this courseware has a high degree of artistry. Such courseware is a good content and the unity of the form of beauty, the form of beauty can stimulate the interest of students, a better expression of the content. However, taking into account the current level of courseware preparation is generally not high, the requirements of this item should not be high. Standard Two:
I. Educational
1, intuitive: the production of courseware intuitive, image, conducive to students' understanding of knowledge.
2, interesting: help mobilize students to learn enthusiasm and initiative.
3, novelty: the design of the courseware is novel, and further mobilize students' enthusiasm for learning.
4, inspirational: courseware in the classroom teaching has a greater inspiration.
5, relevance: the courseware is targeted and complete.
6, innovative: can support cooperative learning, independent learning or inquiry-based learning mode.
Second, technical
1, multimedia effects: the production and use of courseware on the appropriate use of multimedia effects.
2. Interactivity: the courseware is highly interactive.
3. Stability: the courseware should not fail during commissioning and operation.
4, easy to operate: easy to operate, fast.
5, portability: whether it is easy to transplant, can run normally in different configurations of the machine.
6, easy to maintain: courseware can be easily updated, conducive to communication, improve.
7, reasonableness: whether the courseware is the appropriate choice of software type.
8. Practicality: whether the courseware is suitable for teachers' daily teaching
III. Artistic
1. Picture art: the picture production should have a high degree of artistry, and the overall standard is relatively uniform.
2, language and text: the language and text displayed in the courseware should be standardized, concise and clear.
3. Sound effects: the sound is clear, no noise, and has a role in enriching the courseware.
Question 7: What are the characteristics of multimedia authoring tools function A. What is a multimedia authoring tool?
Multimedia teaching software is a computer application with teaching properties. It is the production of a method is to use high-level programming language preparation ---- programming. Such as the use of vbasic, delphi, c + + language, etc., but these computer languages are more specialized, more suitable for professional programmers to produce the use. Not very suitable for the majority of teachers to learn to use.
The other is a specialized tool software production. This specialized software is called multimedia authoring tools, it is also known as multimedia writing tools (author tool) or multimedia editing software. These authoring tools are designed specifically for the production of multimedia software. Most of them have a visual authoring interface and are intuitive, easy, interactive and easy to learn without programming. Very suitable for the majority of educators to learn and use.
Second, the popular multimedia authoring tools
At present, the editor of the popular multimedia authoring tools are foreign: authorware, director, toolbook, action! See as a simple multimedia writing software, just a little less interactive, can be used as a report on the lecture class auxiliary display.
In recent years, there have been a number of multimedia authoring tools for teachers, all of which are easy to learn and in line with Chinese habits of mind.
Third, the classification of multimedia teaching software and the creation process
(a) the classification of multimedia teaching software:
Multimedia teaching software (hereinafter referred to as courseware) can be divided into: guidance, practice, quiz, simulation and game type of the five categories. Some courseware may also be a combination of multiple types. The application of different occasions can be divided into classroom demonstration and individual learning. Classroom demonstration type is mainly for
Teachers in the classroom to support the use of teaching, the program execution is linear. This type of courseware is relatively simple, and can be produced by teachers themselves. Individual learning courseware is mainly for students to operate their own learning and practice. This type of software is generally very interactive and more complex. Can be organized through the project team, by a number of related personnel involved in research and development.
The general production process of courseware includes:
Objective analysis → scripting → material preparation → creation and design → packing and pressing
1 ) Objective analysis: According to the teaching content, clear teaching objectives to be achieved, as well as ways to achieve the teaching objectives ---- analysis of teaching strategies, to determine the framework of the courseware and the method of expression; the overall design of the courseware.
2 ) scripting: the script of the courseware is the blueprint for the design of the courseware, the author should be based on the teaching objectives, to determine the specific performance methods and content of the courseware, up to the specific content of each screen (page) arrangements, such as the emission position of the various media, the media elements appearing at the moment, the interaction mode, and the link to the screen, etc., should be very specific and clear. The design of the script should also be considered according to the characteristics of the creative tools and the psychological characteristics of people receiving information and other comprehensive factors. The design process of the script is actually a creative process, the creativity of the good or bad depends on the degree of understanding of the content and
The level of the creators, the final quality of the courseware has a great role in determining.
3 ） Material preparation: the basic elements of multimedia courseware ---- material has a considerable part to be prepared in advance, such as text, images, sound, animation, images and other raw materials, need to be collected through a certain method or production, and some need to be pre-processing and editing, such as the courseware required for a certain image of the data we can get through the image library (such as the material CD-ROM), or By taking pictures ---- scanner scanning to obtain, or with a digital camera to take pictures, if indeed there is no, we can also use the image production software production.
4) creation design: according to the requirements of the script design, the use of creation tools to create a variety of media materials integrated into a courseware. After the completion of the courseware, but also after the test run test and use evaluation, if necessary, but also for modification. Whether to achieve the desired effect depends on the authoring tools used and the creator's familiarity with the use of software.
5) Packaging disk: the ultimate goal of the production of multimedia courseware is the application of teaching, so in the final stage of the creation of courseware packaging, according to the size of the software and the need to be copied to a floppy disk or CD-ROM production. Become a can be separated from the creation of the environment (in the other did not install the creation of tools on the computer can also run normally) easy to use utility software. You can also put the courseware on the website for ...... as needed. >>
Question 8: What are the advantages and disadvantages of multimedia teaching? According to the date Shang paperless education on media teaching and traditional teaching methods of comparative research:
First of all, the use of multimedia teaching can make the original abstract, boring learning content through the graphics, animation and other forms of expression and become intuitive, enhance the students' interest in learning.
Secondly, it can effectively implement the teacher-led, student-oriented teaching mode. Because the multimedia teaching system has the characteristics of interactivity, integration and multi-dimensionality, therefore, in teaching, can respect the students' individuality, give full play to the role of the teacher, to achieve two-way communication between the teacher and the students, personalized teaching.
Third, it can promote the transformation of the teaching mode which is mainly based on knowledge transmission to the teaching mode which is mainly based on quality education. Multimedia teaching system can create a teaching environment for students to learn independently.
Fourth, multimedia teaching can improve teaching efficiency. In the use of multimedia systems for the teaching process, the teacher can be in the classroom directly using the remote control of the control room in a variety of equipment for remote control, in order to select or control the playback of the teaching program source. If in some important teaching places assembled with a camera, the teaching activities of each teaching place feedback to the main control room for control, the main control room or the principal's office will be able to see the teaching activities on-site situation, teaching managers can easily watch the teaching process, is conducive to teaching observation and teaching management.
Modern teaching methods and traditional teaching methods have many advantages, but there are also many problems, if not properly handled, it will not achieve the desired teaching results.
First, high cost and large investment. The configuration of other teaching hardware facilities such as computers takes up a lot of teaching funds. Secondly, the opportunity for teachers to communicate directly with students is reduced, and there is a lack of psychological communication.
Third, the teaching speed is too fast, the students can not keep up with the notes, can not keep up with the ideas, affecting the effect of listening.
Fourth, information overload, due to the large capacity of information, the content of the lecture, on the spot digestion difficulties.
Fifth, the production of courseware takes a lot of time, and it is easy for teachers to relax their research on teaching materials and teaching methods.
Sixth, too much dependence on the teaching environment and facilities, losing the flexibility and diversity of teaching methods. The teaching process is too much affected by objective uncertainties, such as power outages, network and computer operation failures, weak light in the classroom, lack of teachers' operating skills, etc., will delay the teaching time, which in turn may affect the entire teaching process.
Question 9: Y what is multimedia courseware 40 points Multimedia courseware "is simply a tool used by teachers to assist in teaching and learning, the creators according to their own creativity, the first from the overall classification and organization of information, and then the text, graphics, images, sound, animation, video and other media materials in time and space to integrate them into one and give them the ability to interact. And give them to the integration of interactive features, so as to produce a variety of exciting multimedia application software products.
Hope to adopt!
