The role of multimedia in teaching

Question 1: What are the advantages and disadvantages of multimedia teaching? A comparative study of media teaching of jujube merchants based on paperless education and traditional teaching methods;

First of all, the use of multimedia teaching can make the original abstract and boring learning content intuitive through graphics, animation and other forms of expression, and enhance students' interest in learning.

Secondly, it can effectively implement the teacher-led and student-centered teaching mode. Because the multimedia teaching system is interactive, integrated and multidimensional, we can respect students' personality, give full play to teachers' role, realize two-way communication between teachers and students and carry out personalized teaching.

Thirdly, it can promote the transformation from the teaching mode based on knowledge transfer to the teaching mode based on quality education. Multimedia teaching system can create an autonomous learning environment for students.

Fourthly, multimedia teaching can improve teaching efficiency. In the process of teaching with multimedia system, teachers can directly use the remote controller to remotely control various devices in the classroom control room to select or control the teaching program source. If cameras are installed in some important teaching places and the teaching activities of each teaching place are fed back to the general control room for control, the general control room or the principal's office can see the teaching activities, and the teaching managers can easily observe the teaching process, which is beneficial to teaching observation and teaching management.

Compared with traditional teaching methods, modern teaching methods have many advantages, but there are also many problems. If it is not handled properly, the ideal teaching effect will not be achieved.

First, the cost is high and the investment is large. The configuration of computer and other teaching hardware facilities occupies a lot of teaching funds. Second, the opportunities for direct communication between teachers and students are reduced, and psychological communication is lacking.

Third, the teaching speed is too fast, and students' notes and ideas can't keep up, which affects the effect of listening to lectures.

Fourth, the amount of information is too large, and it is difficult to digest it on the spot because of the large amount of information and many teaching contents.

Fifth, it takes a lot of time to make courseware, which is easy for teachers to relax their research on teaching materials and teaching methods.

Sixth, relying too much on teaching environment and facilities has lost the flexibility and diversity of teaching methods. The teaching process is greatly influenced by objective uncertain factors, such as power failure, network and computer failures, poor classroom lighting, and lack of teachers' operating skills. This will delay the teaching time and may affect the whole teaching process.

Question 2: What are the advantages and functions of using multimedia teaching? Thank you's 20-minute multimedia technology teaching can integrate pictures, texts, sounds and images, making teaching and learning activities more colorful, and can also contain vivid images of knowledge learning, skill training and intellectual development, thus stimulating students' interest in learning, turning hard learning into interesting learning and enriching students' imagination.

Question 3: What are the functions of multimedia courseware in teaching? 1. Multimedia courseware is conducive to creating situations and better stimulating students' interest in learning.

2. Multimedia courseware is conducive to scene reproduction, guiding students to feel the text.

3. Multimedia courseware helps to turn abstraction into intuition and cultivate students' thinking ability.

4. Multimedia courseware is conducive to breaking through the time and space constraints and promoting the development of students' thinking.

(1) Show the macro and micro world with the help of multimedia courseware.

⑵ Demonstrate the changing process of things with the help of multimedia courseware.

⑶ Display physical images from multiple angles with the help of multimedia courseware.

5. Multimedia courseware helps to increase practical ability and improve students' application ability.

Question 4: How to play the role of multimedia in teaching is the need of educational reform and development, and it is also the development direction of teaching reform. At present, multimedia teaching equipment has spread to all kinds of schools at all levels, including the most basic rural primary schools. Teachers' enthusiasm for applying multimedia equipment to teaching is very high, especially in high-quality class competitions. People generally like to use multimedia teaching in open classes, thinking that without multimedia, they can't give full play to the advantages of classroom teaching and can't have a good class. Indeed, the use of multimedia in teaching can solve many problems that were difficult to solve in the past. Through multimedia teaching, the phenomenon can be more intuitive, the effect more obvious, the students can accept it more easily, the teachers can relax and the classroom capacity is larger. It does show the benefits of multimedia teaching, but I think we should grasp several principles when applying multimedia to teaching. First of all, we should make full use of multimedia teaching in physics teaching and change the traditional teaching methods. In the past, we emphasized the role of experiments in teaching. In classroom teaching, we get phenomena through teachers' demonstration experiments and draw conclusions through students' own experiments. But the effect of some experiments is not obvious, and we can only draw conclusions by imagination. For example, when talking about current, the directional movement of charge forms current, and whether the charge really moves can't achieve this effect. When playing through multimedia, the effect is very obvious.

Question 5: What is the function of multimedia teaching? What are the teaching methods? The application of multimedia computer-aided teaching can stimulate learning interest, mobilize learning enthusiasm and improve the quality and efficiency of classroom teaching. What are the teaching methods? 1) Language methods: including lecture method (telling, explaining, reading and talking) and conversation method (inspiring, asking and answering, guiding conversation). (2) Intuitive methods: including demonstration, visit and field trip. (3) Practice methods: including practice (oral practice, written practice and operation practice). (4) Methods of autonomous learning: including reading guidance, discussion and cooperation. In short, the choice of teaching methods should be based on teaching objectives and tasks, subject characteristics and learning content, students' age characteristics, teaching environment and teaching equipment.

Question 6: How to give full play to the teaching function of multimedia technology;

First of all, teachers should "know how to use"

Mankind has entered the information age, and the continuous development of modern technology with computers and networks as the core is changing our production mode, lifestyle, working mode and learning mode more and more profoundly. In primary school mathematics teaching, multimedia-assisted teaching should be properly selected in time, and teaching style scenes should be created with concrete images, words, sounds and images, so as to make abstract teaching content concrete and clear, make students' thinking active, participate in teaching activities with interest, make them pay attention to practical operation, scientifically remember knowledge, help students play their subjective initiative and actively think about problems, and make teachers' teaching orientation become students' learning orientation. Mathematics teachers should study how to use modern information technology to help their own teaching from the perspective of their own disciplines, and integrate modern information technology into the teaching of minority subjects ―― just like using blackboards, chalk, paper and pens, it is natural and smooth, so that school education will develop towards independent and distinctive curriculum teaching.

Teachers must be proficient in using multimedia equipment, be familiar with and learn to design and write multimedia teaching software, and truly master the theory and skills of modern educational technology, so as to play their due role in the education and teaching reform and meet the challenge to educators in China in the 2 1 century.

Based on this, we can let teachers participate in some training, invite some experts to give lectures or improve their ability to use multimedia technology through self-study by teachers.

Second, teachers should make good use of it.

The characteristics of primary school mathematics are abstraction and generalization, while the age characteristics of primary school students are easy to accept intuitive images. Reasonable and appropriate use of multimedia-assisted teaching can not only strengthen intuition and help abstract generalization, but also effectively avoid learning weariness, reduce students' excessive learning burden, and keep students excited, happy and curious. This has played an important role in optimizing the mathematics classroom in primary schools.

(A) the use of multimedia guidance, the creation of learning situations, to stimulate students' participation motivation and interest.

Creating a situation is to induce students to be in a vivid learning scene through the situation created by teachers, introduce new lessons vividly and skillfully, entertain and entertain, and make students curious and eager for new knowledge in a pleasant situation, thus improving their learning enthusiasm. If we can properly use multimedia courseware to complete this process, it will get twice the result with half the effort. For example, when teaching "the understanding of circle", the teacher asked the students at the beginning: "What shape is the wheel?" Students think this question is too simple, so they answer with a smile: "round", and the teacher asks: "Why did you make a round one?" At this time, the students don't know how to explain. The teacher said, "Today, the teacher took everyone to see the performance of animals in the sports meeting." Play rally: pigs drive square wheels, rabbits drive oval wheels and monkeys drive round wheels. When the game started, all the students laughed. At this time, teachers can design some commentaries to increase the atmosphere. He said, "What happened to piggy and bunny's car today? It's up and down, and it's hard to drive! Little monkeys are the easiest, much more stable than them, and they are fast. Students, why do you say that? " The situation created in this way gives students a sense of freshness, so that students can experience the math problems around us and realize the significance of problem thinking. So as to encourage students to actively participate in classroom learning and form a good learning atmosphere.

(2) Turn static into dynamic, and break through teaching difficulties.

The teaching content of mathematics is abstract, and some traditional teaching methods are not effective, so some contents are difficult for students to master, which forms the difficulty of teaching. The focus of teaching is what students are required to master in the teaching process. Traditional teaching often spends a lot of time and energy on highlighting teaching key points and breaking through teaching problems. Even so, students are still not deeply touched, and they are easily tired or even bored. Changing teaching methods is an effective way to highlight key points and break through difficulties. Due to the concrete image of multimedia, the combination of dynamic and static, and the combination of sound and emotion, if properly used, it can turn abstract into concrete, mobilize the synergy of students' various senses, and solve the content that teachers can't explain clearly and students can't understand, so as to effectively achieve intensive lectures, highlight key points, break through difficulties, and achieve teaching effects that traditional teaching methods can't match.

For example, when teaching "cylinder".

Question 7: What do you mean by the advantages and optimization of multimedia teaching? Please refer to.

Quality education is the trend and mainstream of current education reform. The implementation of quality education should run through the classroom teaching of specific subjects, and classroom teaching is the key and main channel to implement quality education. First of all, only by changing the teaching concept can we reform the teaching mode and optimize the classroom design by using multimedia information technology. Taking students' learning as the center and conforming to the teaching law and students' cognitive law as the premise, rational selection of multimedia can greatly exert its advantages, which is conducive to the implementation of quality education and the cultivation of students' memory and thinking abilities.

First of all, the author expounds what is quality education and the role of multimedia technology. Then, it specifically analyzes the role of multimedia-assisted teaching in promoting quality education:

Proper use of multimedia can cultivate students' active learning ability. This is reflected in two aspects. First, teachers design, make or choose multimedia courseware suitable for teaching content and teaching objects, and organically run through their own teaching objectives and learning-oriented teaching ideas; Second, in the process of watching multimedia courseware, students can stimulate their brains to review and reproduce the original or learned knowledge, and creatively apply the old knowledge to learn new knowledge, at the same time arouse their interest, curiosity, memory and emotion in new knowledge, thus generating the desire of active learning. The author cited the multimedia courseware of "meiosis" and "homologous chromosomes" in biology teaching to illustrate this point.

Multimedia environment can effectively promote memory and cultivate memory ability. Multimedia integrates pictures, words, sounds and images, which means that the visual and auditory centers of students' brains are in an exciting state, and relevant knowledge will leave a deep impression on their brains. Multimedia conforms to the process of human memory. Multimedia shows the connection of knowledge space, systematizes knowledge and forms a network, which is beneficial for students to compare, process and summarize knowledge and form a memory based on understanding.

Multimedia-assisted teaching is helpful to cultivate students' analytical and inductive thinking ability. Multimedia teaching is convenient to provide students with knowledge materials, and each student can build a knowledge system according to his own cognitive structure, which provides great convenience for teachers to change "conclusion teaching" into "process teaching". The author uses the teaching of breathing method to illustrate this point.

Multimedia-assisted teaching is helpful to inspire innovative thinking and cultivate innovative ability. Multimedia-assisted teaching can optimize classroom design, give full play to students' dominant position, create a democratic, harmonious and equal atmosphere, facilitate the mobilization of students' learning enthusiasm and give full play to students' dominant role, thus enabling students to establish innovative consciousness and improve their innovative ability. The author uses the teaching of "the discovery of photosynthesis" and "the discovery of auxin" to illustrate this point.

The author's analysis has been thorough, and what I feel most about multimedia is that it can improve the efficiency of class. Because teachers don't have to write books on the blackboard when giving lectures in class, it can save a lot of time. But it is necessary for students to concentrate on 12 and take notes carefully, because if you are not careful, you will miss your notes, so you will not be absent-minded. If you really miss the content, you can watch it after class. Another point is that students should read, listen and write. The so-called eyes look at six roads, hands look at six roads, and ears listen to all directions. Therefore, the whole class process must be highly focused. However, some courseware is too vivid and will distract students' attention. For example, some teachers put a lively little animal in some corners, which has nothing to do with classroom teaching. Although it can stimulate students' interest, it is easy to have a negative impact. Therefore, it is necessary to use multimedia teaching reasonably. Therefore, the more you use multimedia, the better the effect. Teachers should properly choose multimedia according to students' cognitive rules and characteristics, so that multimedia can become a tool to enlighten students' cognition and thinking, rather than a tool to display teaching content.

Practice and Exploration of Network Teaching

Entering the 2 1 century, with the continuous development of computer network technology and Internet, online teaching has become a reality. The so-called online teaching means that teachers use computer networks to transmit teaching information to students, or students acquire learning knowledge through computer networks. Of course, it also includes teaching resource scheduling, teaching plan management, student status management and so on. Because online teaching has the characteristics of timeliness, enjoyment, interaction and personalization, how can teachers give full play to the leading role of teachers in the teaching process according to different teaching modes of online teaching, stimulate students' autonomous learning and make students become the subject of understanding? It is necessary to understand the teaching mode and characteristics of online teaching, and constantly practice and innovate in teaching work.

Multimedia teaching network

Question 8: How to use the advantages of multimedia technology to promote subject teaching? The application of multimedia is the fastest developing and most active technology in the field of information technology, and it is also the focus of the development and competition of the new generation of electronic technology. Multimedia is a computer application technology that comprehensively processes text, images, graphics, animation, audio, video and other information by computer. Using multimedia technology to assist classroom teaching has been widely used in the development of modern educational technology.

First, the advantages and disadvantages of multimedia teaching in teaching

The advantages of multimedia education technology are incomparable to traditional teachers. It is interesting and intuitive, which is not available in traditional teaching methods. It can fully mobilize the enthusiasm, initiative and creativity of teachers and students, break through the difficulties in teaching, thus making it easier to achieve teaching objectives and enabling students to acquire knowledge in a pleasant and relaxed environment. In addition, the repeatability and interactivity of multimedia courseware also give full play to the advantages of multimedia technology. Therefore, multimedia-assisted teaching has gradually become one of the mainstream teaching technologies. As the front-line educators of secondary vocational education, we are constantly exploring the role of multimedia in promoting modern education, gradually improving multimedia-assisted teaching methods, and contributing to the modernization of secondary normal education.

However, multimedia teaching also has its inherent shortcomings and many negative effects.

First of all, some teachers rely too much on multimedia courseware. This will make the interaction between teachers and students useless, and it is difficult for students to play the main role in the classroom. Second, the content of the courseware is flashy. Third, multimedia production needs technical support. Fourth, "auxiliary" teaching is regarded as "alternative" teaching.

Second, make use of the advantages of multimedia technology to promote its application in teaching.

The new curriculum reform advocates the use of information technology equipment in the classroom and the organization of teaching through multimedia means. Multimedia intervention in the classroom breaks the traditional indoctrination teaching mode and is an important symbol of the modernization of teaching methods. Multimedia is used to assist teaching, and its starting point and destination are to improve teaching effect. Teachers' over-reliance on multimedia teaching not only can't give full play to the advantages of multimedia teaching, but also may be counterproductive, resulting in the phenomenon of "full house irrigation" in disguise. As a teacher, we should first grasp our leading position and role in teaching, and carefully use, apply and use a lot of media. Only in this way can multimedia teaching be more scientific and reasonable.

1, in math class, using multimedia to strengthen abstract thinking.

For students in secondary vocational schools, especially liberal arts students, like our kindergarten teachers. They are not very interested in mathematics. One of the reasons is that the content of mathematics course is too abstract for students to understand. However, the use of multimedia technology can not only show students concrete images, make them experience the relationship between images and abstraction, but also improve their mathematical thinking ability. Multimedia students have two major difficulties in secondary vocational mathematics: plane geometry and solid geometry and application problems. You can use courseware to make some three-dimensional renderings, so that they can easily understand the meaning of the questions and solve problems. Another example is that teachers make courseware for the "opposite" and "opposite" application problems when they cross the bridge, and use many different ways to express the relationship between distance, time and speed when they meet. The use of multimedia courseware can not only improve students' enthusiasm and curiosity, but also enable them to learn mathematics actively.

2. In English class, multimedia is used to enhance the audio-visual effect.

Students in kindergarten teachers' schools generally work in kindergartens after graduation. However, nowadays kindergartens generally start bilingual teaching from small classes. This shows the importance of students learning English. In the traditional teaching mode of blackboard and chalk, a single teaching method is easy to make students feel bored, but the use of multimedia can greatly stimulate students' learning enthusiasm. Bring students to a colorful audio-visual world to study freely. In addition, under the traditional teaching mode, English teachers have a heavy workload of writing on the blackboard in class. In the multimedia teaching mode, the courseware used by teachers is made in advance, and the efficiency is obviously improved by clicking the mouse in class.

3. In chemistry class, multimedia is used to strengthen the demonstration of experimental effect.

As we all know, chemistry assists experiments, but many chemical experiments are toxic and dangerous. What can we do at this time, as long as a multimedia animation can solve all the problems, such as sulfur spontaneous combustion. Some experiments that are not easy to see the experimental effect immediately can also be demonstrated in a few minutes with multimedia, which not only saves time, but also accelerates the pace, enlivens the atmosphere and makes the experimental phenomenon more obvious.

4. In physics class.

Question 9: What are the benefits of learning multimedia technology for kindergarten teaching?

1, optimize the teaching content. Multimedia teaching can vividly display teaching contents, enrich teaching forms, make teaching contents visible, audible and easy to perceive and understand, expand teaching information, broaden children's knowledge, help children perceive and understand new knowledge, and understand the laws and changes of things in exploration. For example, in the "role of magnets" in small class science activities, multimedia technology is used to show the objects that magnets can attract one by one, and the original boring content is made intuitive and easy to understand through courseware.

2. Optimize the teaching situation. Interest is the best teacher. Using relaxed, lively, smooth and free situations can effectively stimulate children's learning motivation. Multimedia teaching can also integrate teaching and demonstration. In the colorful and changeable information two-way transmission, children learn happily, naturally and actively. Therefore, multimedia technology has created a good scene for kindergarten teaching activities and created a relaxed and natural learning atmosphere. For example, in the "classification and counting" activity of mathematics in middle class, the abstract and boring teaching content is transformed into vivid and interesting teaching software, and the form of penguin magic and playing games with children runs through the whole activity. Whenever the computer shows that the little penguin is singing beautiful songs while flapping its wings, bringing out all kinds of colorful geometric figures and piecing together beautiful pictures, this colorful and varied visual picture greatly stimulates children's desire to learn. At the same time, the computer judges whether the children's answers are correct, vivid and harmonious by singing or being angry with the little penguin, which optimizes the teaching situation.

Question 10: How to give full play to the effective role of multimedia in classroom teaching? First of all, multimedia courseware can give full play to students' subjective initiative, stimulate experimental interest and cultivate the spirit of inquiry.

In science teaching in primary schools, we should use a variety of teaching media to cultivate students' innovative ability, and carefully design the timing and usage of modern educational technology, so as to achieve the best timing and usage of modern educational technology. Teachers present the learning content through the media, guide the learning direction, and let students' eyes, ears, brains and other organs participate in the whole process of teaching activities. Students get the maximum information capacity in unit time, which strengthens their attention, association, language understanding and expression ability, thus improving their learning ability. The best opportunity of modern educational technology should be to give students a more vivid and intuitive picture when they have a strong interest in learning content and are eager to express their thoughts and thoughts, so that the language preserved by students can burst out under the specific image provided by modern educational technology, thus achieving the best effect. For example, in the teaching of "sound transmission", some different types of sounds are played through multimedia at the beginning, so that students can judge their own voices. In the teaching process, we should follow the direction of * * * self-made courseware "The Spread of Sound" to stimulate students' interest in learning, create concrete and intuitive teaching situations, and resolve the key and difficult points in teaching. In addition, some extra-curricular knowledge has been added, such as a device for playing astronauts talking on the moon with video, which further broadens students' knowledge and provides a broad space and environment for students' innovative learning. Also, when reviewing, I present some related questions and exercises in the form of games, imitating the puzzle game program of Happy Dictionary, so that students can master knowledge and learn to learn when they pass the test.

Another example is the teaching of the course "Properties of Electromagnets". When teachers use multimedia courseware to show ducklings swimming and paper butterfly magnet toys flying by themselves, the visual sense immediately activates the pupils' nature of loving and liking small animals, and then shows good psychological mood and strong interest. With the teacher demonstrating these toys one by one, the students' activated psychology and good mood make them pay great attention to the teacher's demonstration, and sprout an essential and primitive inner desire from the deep heart to understand this phenomenon. When this increasingly strong inner demand turns into a huge driving force, students' own instinct makes them have a desire-the desire to explore, so they can't help but devote themselves to interesting exploration activities. Therefore, it is very necessary to grasp the seedlings of students' interest, stimulate students' interest in learning, induce their desire to explore actively and create an effective classroom atmosphere. .

Secondly, multimedia courseware can improve students' observation ability, thinking ability and imagination ability.

Experiment is the most commonly used and important teaching method in science teaching, which plays an important role in helping students understand and master theoretical knowledge and cultivating their practical ability. Especially after the new curriculum reform, students pay more attention to finding evidence and draw correct judgments and scientific conclusions. Observation is a kind of perceptual activity that uses the senses to perceive things purposefully and systematically. The application of modern teaching media (video, projection, network, multimedia, etc.). Integrating science teaching can greatly improve learning efficiency, save teachers' energy, and integrate students' classroom learning with observation, operation, inquiry, discussion and interactive learning, so that students can fully experience the process of scientific exploration. So when I was teaching compressed air, I did a test in the middle class I taught. The results show that the experimental class has certain advantages over the control class.
