The ingenious design at the beginning of a class is conducive to creating a good classroom teaching situation. The use of multimedia in this link can stimulate students' strong thirst for knowledge and improve their learning enthusiasm. Therefore, when introducing new classes, it is a favorite way for teacher China to use multimedia in time. Take my teaching "Fish Swim to the Edge of Paper" as an example. At the beginning of the new class, the topic is first shown in the form of animation: in the animation, several fish swim happily in the water, swimming, and actually swimming on a piece of white paper. At this time, the screen printed the title-"Fish swam to the paper". On the screen, vivid pictures and interesting music immediately attracted the students' attention. At this time, students will show great interest and guide them into the new text they have learned. After reading the question, I asked the students, "What do you want to learn from the article?" At this time, the students became active and asked, "Did the fish really swim to the paper?" "Why did the fish swim to the paper?" Multimedia settings, creating suspense effect is really obvious. It vividly shows us the impossible. How can we not catalyze students' curiosity? They are all eager to find the answer from the class. Driven by such a strong desire to learn, their learning process must be positive.
(2) Additives for creating atmosphere and rendering emotions
In classroom teaching, sometimes there will be a scene that makes our teacher very embarrassed: an article with profound feelings, the teacher has already done as the Romans do, but most students are indifferent and indifferent, and the emotional experience has appeared the phenomenon of "shaving their heads and carrying loads". The rational use of information technology can help us create a good situational atmosphere in teaching, which often produces the effect of "no melody before love" and receives a miraculous effect with half the effort.
During the teaching process of "Soldiers in White Forever", I made a survey of the students, and found that due to the influence of age characteristics, the students knew little about the "SARS" disaster that impressed us deeply in 2003. Without realizing the seriousness of the situation at that time, you can't appreciate the noble demeanor of the characters. Then, how can we make them enhance their understanding of SARS and further understand the lofty quality of Ye Xin's self-sacrifice, thus generating a strong spiritual shock? After studying the textbooks repeatedly, I decided to start with Ye Xin's memorial service to stimulate students' emotions, outline and guide students to study the text in depth. To this end, I collected a large number of relevant materials and carefully produced relevant teaching courseware. In the classroom, in the heartbreaking sadness, when the scene of wreaths like the sea and tears like rain appeared in front of the students at Ye Xin's memorial service, everyone was shocked: an ordinary head nurse, why did so many people come to see her off after her death? Why do people call her "the warrior in white forever"? Looking at the children's surprised eyes, I introduced them to the panic and harm caused by SARS, and let them browse the general situation of life in Ye Xin. The design of this link has created a good teaching atmosphere, played a good role in rendering students' emotions, and played an important role in affecting the whole body.
(C) colorful and passionate reading enhancers
Using modern educational technology, the silent language materials in the text can be transformed into sensible sounds, so that the language images and emotions in the text can quickly penetrate into students' hearts, so that students can be intoxicated with their own voices and feelings and stimulate their desire to read aloud. A text full of beautiful colors, such as "Color Pool", is definitely subject to many constraints in the display of words. However, with the intervention of multimedia, the teaching effect has been significantly improved: with the beautiful melody and beautiful recitation, the colorful pools on the screen have different shapes, and all kinds of lights are shining under the sunlight, which is really magical, magnificent and wonderful. The unique charm of the picture is deeply imprinted in the students' minds and cannot be forgotten. Back in the text, the students' mood is at its best, and a cheerful and lively mood rises in their hearts, which promotes the strong desire of "I want to study". At this time, I take advantage of the situation and guide students to devote themselves to the teaching of reading texts with admiration for colorful pools. As students successfully enter the situation described in the text, they are infected by the magic and beauty of colorful pools, and the passion of reading aloud arises spontaneously.
Second, the use of multimedia teaching to break through the difficulties of Chinese teaching
Obstacles in students' language learning and writing are the difficulties in our teaching. The teaching difficulties of a class often have a certain distance from the students' existing knowledge, which makes students feel confused in their study. The reason is that knowledge is too abstract, too complicated, or too strange. To solve this difficulty, the teacher's explanation alone is often counterproductive. At this time, teachers can play the role of audio-visual media, display knowledge intuitively, vividly and accurately, help students get rid of thinking obstacles, realize a deep understanding of new knowledge, and then highlight key points, break through difficulties, promote knowledge internalization, and achieve the teaching goal of improving their ability.
(A) Turn difficulties into simplicity
In Chinese teaching, it often takes a lot of time and energy to highlight the teaching focus or breakthrough and solve the teaching difficulties. But in this way, students' feelings are still not deep, and they are easy to get tired and even bored. Audio-visual media can activate the scene of the text content, turn the difficult into the easy and promote students' understanding of the text content.
For example, in Zhan Tianyou's teaching, it is said that Zhan Tianyou designed a herringbone line along the mountain. Because these contents are far from students' real life, it is difficult for students to understand and accept the literal knowledge in the rigid literal description. In order to smooth the teaching slope and break through the teaching difficulties, I used the audio-visual media in teaching to design such an animation teaching link: a train, two locomotives move north, the front locomotive pulls, the rear locomotive pushes, and when passing the fork of the herringbone line, it is reversed, and the original locomotive pulls and the original locomotive pushes, so that it can easily climb the steep slope. The animation allows students to watch the whole process of the train climbing the straight slope, and pay special attention to the climbing trajectory of the word "person" flashed in red. Then I asked the students to express their opinions freely according to what they saw, and to talk about how the train climbed the steep hillside, so as to achieve the teaching purpose of deepening the understanding of the text. Thanks to the ingenious use of audio-visual media, students can easily understand the meaning of "herringbone" circuit in a short time, and more specifically appreciate the wisdom and outstanding creative spirit of Zhan Tianyou Superman.
(B) the abstract into concrete
In Chinese teaching, some notional words contain very abstract meanings, which are difficult for students to understand only by the teacher's explanation. If multimedia is used to assist teaching, the reading effect will be twice as effective.
For example, in the rich teaching process of Xisha Islands, students didn't understand the meanings of the words "coastal defense outpost" and "south gate of the motherland" involved in the article, so I first showed the map of China with the media to show the students the map and told them that Xisha Islands is at the southernmost tip of the motherland, and its geographical position is very important, just like the gate of our home, so it was called "south gate", and the students naturally accepted this new meaning.
(C) change static to dynamic
In Chinese teaching, there is often a lot of natural science knowledge. For example, the article "Watching the Solar Eclipse" introduces the causes and process of the solar eclipse to students. Students have little knowledge of astronomy, and the astronomical spectacle of lunar eclipse is not always seen. In order to let students intuitively understand how the solar eclipse was formed and the whole process of the solar eclipse, I used courseware to show three celestial bodies through animation. The sun is the center, the earth revolves around the sun, the moon rotates by itself, and the three balls move at the same time. When the moon moves around the earth to the shadow area of the earth in the sun, the moon gradually darkens from part to all. At this time, there is a partial solar eclipse and the moon. On the screen, the whole process of the eclipse vividly reappears in front of the students, allowing them to be there. The cause and process of the solar eclipse, which is difficult to explain in many languages, are vividly demonstrated in a few seconds of animation.
Another example is the article "Looking at the weather from the clouds". There are three types of clouds: Cirrus, cirrocumulus, Cumulus and Cumulus. These concepts are also abstract and difficult to distinguish. We can use multimedia to show pictures of various clouds in front of our classmates, and then guide students to understand the text and solve difficulties according to proverbs in life and phenomena observed by students. At the same time, multimedia can also be used to show students' personal experience of "seeing the weather in the clouds".
(D) Break through the time and space constraints
Audio-visual education media can not be limited by time and space, but can change the micro and macro constraints, directly express various things and phenomena, so that some things that students can't actually contact in teaching can be displayed through sound and pictures, broaden students' horizons, obtain the materials needed for learning, and provide students with concrete and vivid images, thus breaking through the teaching difficulties.
For example, in the class of "The Rich Xisha Islands", combined with the content of the text, I played some videos depicting the beautiful beaches, islands and underwater world in time, which were dynamic and vivid. The students watched the beautiful scenery of the beach and the island for a while, which made them seem to see the endless beach, with shells of different shapes and huge and interesting turtles everywhere. The island is shaded by trees; For a while, it seemed to dive into the bottom of the sea again and explore the secrets of the bottom of the sea. In the depths of the sea, countless fish swim around and keep shuttling, and beautiful corals have different shapes, as if they heard various sounds from underwater animals. During the whole watching process, the students were as if they were there, with highly concentrated thoughts and high emotions.
It can be seen that audio-visual media has narrowed the distance, made virtual reality easier, and made complex and arduous cognitive activities simple and easy, thus helping students to alleviate the difficulties in abstract thinking, logical thinking and language understanding and expression, reducing the difficulty and making the difficulties in teaching break through smoothly.
Third, use modern educational technology to change students' learning style.
In the traditional teaching process, everything is dominated by teachers, and students can only passively participate in the whole process from teaching content, teaching strategies, teaching methods to teaching steps.
The new Chinese curriculum standard puts forward that in Chinese teaching, we should actively advocate independent, cooperative and inquiry learning methods. This concept not only emphasizes the change of learning methods, but also emphasizes that the subject of learning and development is students, and the subject position of students in Chinese teaching has been reconfirmed.
In the information technology environment, two modes, personalized learning with students' independent exploration as the main form and network-based consulting learning, are the concentrated embodiment of the learning methods advocated by the new curriculum standards. With the help of interactive learning environment such as modern educational technology, students can equally own and enjoy human learning resources, and can choose learning content, methods, strategies and development goals according to their own learning foundation and interests. In this open learning space, students have the possibility of active participation and a world of autonomous learning. Therefore, integrating information technology into classroom teaching can build a new learning mode of "autonomy, cooperation and inquiry", which fully embodies the multidirectional, rich and fast information exchange. We can provide students with three-dimensional opportunities for multi-directional communication through various modes of friendly cooperation, such as teacher-student interaction, student-student interaction, teacher-machine interaction, teacher-machine interaction, vitality interaction and vitality interaction, which is conducive to cultivating students' cooperative spirit.
For example, when I was teaching Qin Terracotta Warriors and Horses, I made full use of multimedia network for teaching, and designed the following teaching links, so that students could make independent exploration and cooperative exchanges around the following issues: ① Search for relevant information about Qin Terracotta Warriors and Horses on the Internet; (2) Self-study the article "Qin Terracotta Warriors and Horses" by using the found information; ③ Interactive problem solving; Introduce the Qin Terracotta Warriors and Horses you learned from the Internet in your own way.
This kind of teaching design gives students the initiative of learning completely, and the teacher's role changes into the guide and organizer of learning activities, so that students can truly become the masters of Chinese learning. They use different methods and tools to accomplish the same task through information technology. They not only felt the scale of Qin Terracotta Warriors and Horses, but also felt the long and splendid culture of the Chinese nation and the wisdom of the ancients, which inspired students' national pride. This further proves that the involvement of information technology has changed students' passive listening and rote learning methods in the past, thus turning into personalized learning methods of active participation, discovery, exploration and full expression.
Fourthly, using modern educational technology to optimize teachers' teaching methods.
The new curriculum goal puts forward substantive content and specific requirements for teachers to fully implement quality education under basic education. The goal is to pay attention to students' learning, let them learn to learn, and promote their all-round development and lifelong learning. Under this background, as teachers, while actively participating in this curriculum reform, we should reflect on the educational concept and teaching process in time, re-examine our teacher role and change our teacher role as soon as possible to meet the requirements of the new curriculum objectives.
In the traditional teacher-centered "transmission" teaching method, teachers are the givers of knowledge and students are the receivers of knowledge. The basic process of learning is students' perception, understanding, consolidation and application. Teachers speak, demonstrate and demonstrate on the platform, and students absorb, remember and store them accordingly. They circle the key points in class and copy and recite them repeatedly after class. Facts have proved that the biggest drawback of this teaching method with exam-oriented ability is that it stifles children's creativity and innovative spirit.
In the information-based education environment, teachers no longer regard whether they can explain the teaching materials clearly and thoroughly as an important criterion for classroom teaching evaluation. In the information-based education environment, the role of teachers must be fundamentally changed, from "acting" at the front desk to "guiding" at the back desk, which requires teachers to delve into teaching materials, devote more energy to providing students with rich and orderly learning materials, create the best learning environment for students, mobilize their interest, enthusiasm and initiative in learning, organize students to think and explore deeply in the learning process, and make them study happily and consciously in a lively atmosphere, so as to maximize their learning.
For example, in the lesson "I love Yangmei in my hometown", through analysis, I first made it clear that the teaching focus of this text is to let students know the beauty of Yangmei tree and the cuteness of Yangmei fruit, get the education of loving their hometown, and learn the author's method of observing things. In order to give full play to the advantages of modern educational technology, help students enter autonomous learning and better complete teaching tasks, I have consulted a large number of materials. Teaching requirements, description of teaching materials, learning methods, announcer's reading recording, analysis of new words' sounds, shapes and meanings, key words and paragraphs, after-school exercises, pictures and video materials of Myrica rubra trees and fruits, the origin and growth of Myrica rubra, its nutritional value, its edible and medicinal methods, the local industry surrounding Myrica rubra, the joyful scene of fruit farmers harvesting Myrica rubra, the value created by Myrica rubra industry for local people and other related materials are expressed in words, with sounds, pictures and words. In the process of classroom teaching, as long as students really integrate into human-computer interaction, they will inevitably enter the active learning state. At this time, the role of teachers has also successfully changed from "front desk" to "background" and from "actor" to "director", creating the best environment for students to learn independently.
