The main task of teacher teaching is to guide students to accumulate knowledge and expand students' development thinking. As a modern educational technology, audio-visual media can provide visual, intuitive and vivid visual images and visual stimuli. It plays an important role in stimulating students' interest in learning and enriching their perceptual knowledge. In the teaching of primary school Chinese teachers, we should not only use audio-visual means to give students a vivid picture, but should aim at developing thinking, carefully determine the inspiration points according to the key points and difficulties of teaching, and capture the best time to use audio-visual media. Guide students to think deeply, through the perception of image, combine visual, auditory and in-depth thinking, and train the broadness, profoundness and flexibility of thinking. Multimedia technology has injected fresh blood into the Chinese classroom, changed the traditional teaching form of the teacher "chalk + blackboard", and appropriately applied the modern audio-visual media such as physical projection, recording and computer to the Chinese classroom teaching, with light, electricity, sound and image. Static and dynamic, abstraction into concrete, in-depth, is conducive to stimulating students' learning passion, so that students' potential can be better played, which helps speed up the classroom information process and optimize the Chinese classroom teaching process.
First, multimedia makes students' literacy activities more interesting
Students are naturally fun and active, using modern audio-visual media, attracting students' interest through dynamic images, stimulating their cerebral cortex to create a center of excitement, and quickly responding positively to perceived things, making students in a relaxed position. Learn consciously and voluntarily in a harmonious atmosphere. For example, if you teach the word "Cong", the courseware will first show the ears, eyes, mouth, heart, and then the ear will evolve into the word "ear", the eyes will evolve into "ˋˊ", the mouth will evolve into the word "mouth", and the heart will evolve into the "heart". Words, in the blink of an eye, a word of "Cong" appears; like the word "Sen" in teaching, the course pieces are successively appearing from the top, the left, and the right, and the trees are growing in the middle, then flashing into the middle, then flashing into A "森" word. The wonderful picture allows the children to remember the glyphs unconsciously and master the meaning of the words.
In teaching, we often find that students often only pay attention to the general outline of the glyphs. The phenomenon of writing typos sometimes occurs. Some of them are superfluous, some are parts falling off, and some are parts replacement. In the teaching, the modern teaching media is fully used for the glyph teaching. For the parts with easy-to-follow fonts, the eye-catching color is used to compare the characters, especially the key strokes are used to remind the students to pay attention, thus deepening the impression. For example, teaching “drinking†and “thirstâ€, first let the students observe and compare the similarities and differences between the two characters; at the same time of comparison, the courseware uses a striking color to show the difference, while showing the jingle: drinking water to use the mouth Thirsty to drink water. Another example is to use the eye-catching colors and flashing two points next to the wording of the clothes. This will enable the students to deepen their impressions, keeping in mind that there are two points next to the clothes.
In the teaching of the writing of the new words, the modern teaching media can be used to demonstrate the stroke order. The light-colored characters can be presented on the screen first, and then the writing is performed in black with the stroke order, so that the students can remember the writing of the words.
Second, multimedia allows children to experience the situation
Multimedia can break through the limitations of time and space, and reveal the concrete things and phenomena that are difficult for primary school students to perceive in a limited time. In the primary school Chinese textbooks, there are many texts that introduce the famous places in the motherland. For our primary school students, due to the limitations of time and space, their understandings are flawed, which also affects their understanding and experience of the text. In the teaching of such texts, the use of audio-visual media, timely projection, to introduce students to the relevant geographical location, so that students can see at a glance, help students to instantly enter the learning situation, and effective learning. For example, in the course of teaching "Guilin Landscape", after the subject of the book, the students are in a state of eagerness to understand the specific situation of Guilin's landscape, and at this time, a close-up of "Guilin's water" and "Guilin's mountain" can be shown. Students enter the static, clear, green, mountain, show, and dangerous moods, inspiring their love and praise for the beauty of the landscape of Guilin, laying the foundation for students to learn the words in the text, providing a vivid and vivid image. .
Feelings are stimulating to people's understanding and actions. Only when students integrate into the situation and communicate with the image in the works, they can resonate and truly make teaching become the internal needs of students, and achieve the purpose of reading the text, developing ability, and sublimating the emotion.
"Eternal Life in the Sea" is an inspirational and touching text that truly reproduces the grief of the farewell of the people of the country after the death of Deng Xiaoping's grandfather. This touching scene is far from the life of primary school students. Grandpa Deng has done his best for the party and the people, and has died and won the love and respect of the party and the people. In this regard, in order to help the primary school students to understand thoroughly, before teaching this class, students are organized to watch a TV video introducing the deeds of Grandpa Deng to evoke the emotions of the students. In teaching, in order to set off the classroom atmosphere and arouse the emotional resonance of the primary school students, first broadcast the video of Deng’s grandfather’s ashes into the sea, play the sorrowful music, and then create a solemn classroom atmosphere with an emotional lead. Then, while playing the mourning recordings, I read the text emotionally, so that the students can feel the emotional tone of the text as a whole. Through this kind of electrification education, the students' minds and the authors are communicated, shortening the psychological distance between the students and the texts, and facilitating students to generate rich associations when learning the text content to cultivate students' imagination.
The in-depth exploration of multimedia can not only effectively guide students to use their knowledge to analyze, observe, synthesize, abstract, and establish their image, but also enrich the content of incomplete and unspeakable visual materials, and abstract them from many aspects. To sum up, try to say more and update the content to train the students' language and cultivate the students' emotions.
Third, the effective use of multimedia to enrich teaching
Multimedia as an auxiliary means, the role of language teaching should attract the attention of the majority of peers, but this emphasis must adhere to the principle of appropriate and appropriate. Some educators exaggerate the role of multimedia as an auxiliary means, blindly pursuing, blindly thinking that high-quality courses can not be multimedia, multimedia can reflect the modernity of teachers, which will inevitably lead to many misunderstandings of the use of multimedia in the teaching process. Here are some points to the negative impact of inappropriate use of multimedia in the teaching process, hoping to cause peers to think.
1. Improper use of multimedia teaching can make the teaching process mechanized, which is not conducive to students' flexible knowledge and development of thinking.
2. Excessive use of multimedia can shift the role of teachers in a bad direction.
Although multimedia teaching methods can bring us many conveniences and benefits, they are not used as much as possible. Because it is only an auxiliary teaching method, it can't exaggerate its role, let alone replace the creative work of teachers. We can't abandon the reasonable and effective things in traditional teaching methods. The dominant position of teachers in the classroom is not replaced by multimedia. However, some teachers rely on multimedia. Sometimes, a class, students see the teacher playing with multimedia courseware on the podium, busy operating the keyboard and mouse, neither in-depth explanation There is no hard-hitting blackboard, "I only see the machine not seeing people, I can see the picture is not seen", which makes people dazzled. The students' eyes are always on the screen. This is a cumbersome monotony. It is a monotony from the traditional monotony of the past teachers to the new modernization. Sometimes the classroom atmosphere is very busy, the students are very active, and the teacher ignores the teaching density, and the students’ minds are still empty in the after-school. In any case, teachers should be the dominant players in the classroom. Language is a strong subject of "humanity." Some of the subtleties in literary works are difficult to complete, so the role of the teacher cannot be equal to the projectionist. Multimedia teaching can't fall into a flashy situation.
We should continue to explore and study the characteristics of multimedia teaching in the future teaching work, so that it will become more and more perfect, so as to better serve the modernization of Chinese teaching. The primary school Chinese textbooks are rich in content, beautiful in language, rich in image and interesting, and are most suitable for teaching by audio-visual means. The electrified teaching uses its colorful picture to show the meaning of the text and create the desired situation. In the classroom, the framed and silent projection teaching materials, through active guidance, students consciously observe, discover, think, explore, become a line of clear text in the purpose, turned into a sentence of a colorful language, forming a scene of refreshing artistic conception. It plays an important role in cultivating students' ability of listening, speaking, reading and writing, so that the quality of Chinese language is implemented.
