Xunzi, a great educator in ancient China, put forward a long time ago: "If you don't smell it, you will have it, and if you smell it, you will not see it." It can be seen that listening and speaking is the basis of teaching. With the help of computer teaching, we can effectively turn abstract things into concrete things, display the contents that are difficult to understand or important to understand the text with computers, mobilize students' visual functions, and let students maximize their potential through intuitive images and vivid sensory stimulation, so as to perceive more information in an all-round way in a limited time, improve teaching efficiency and activate the internal causes of learning. For example, when teaching Underwater World, the focus of the text is to let students understand the strange underwater scenery, which is difficult for students to understand. In order to smooth the slope of teaching, break through this difficulty and better activate the learning atmosphere of students, I consciously use audio-visual media in the teaching process to let students observe the scenery of the underwater world, supplemented by music explanations, so that students can truly appreciate the magic and beauty of the underwater scenery. Let students see at a glance, effectively solve difficult problems in learning and improve classroom efficiency.
2. Using multimedia helps students to understand ancient poetry.
In primary school Chinese textbooks, ancient poetry occupies a certain proportion. These poems are concise in language, beautiful in mood and profound in meaning. However, due to the narrow knowledge, shallow life experience and poor representation reserve of primary school students, they are alienated from the social times, people's thoughts and customs described in poetry, so the teaching of ancient poetry has always been a major problem in the teaching of small languages. The use of audio-visual media in the teaching of ancient poetry and reasonable use will not only help to stimulate students' interest in learning, develop their imagination, promote their understanding of ancient poetry and poetry, but also effectively cultivate their aesthetic interest. For example, the word "sheng" in the ancient poem "Looking at Lushan Waterfall" and "Rizhao incense burner gives birth to purple smoke" is very wonderful, but it is always difficult for students to understand and experience it only by the teacher's oral explanation. And video just solves this problem. When teaching, the teacher first asks: What does the word "student" mean? Why don't poets use "sound" instead of "sheng" Then guide the students to watch the video with questions. On the picture, the vegetation is lush and green, the dangerous peaks stand upright and the mountains are stacked. At this time, the incense burner peak was shrouded in smoke. Under the sunshine, clouds of purple smoke rose from the valley, and the scenery was very beautiful. Video will transform abstract words in ancient poems into concrete dynamic pictures, giving students a kind of beautiful enjoyment. Students are very interested in learning. They actively observed and thought, and soon realized the beauty of the word "sheng" from the dynamic picture of the incense burner peak: the word "sheng" can only see the smoke rising and dispersing in a short time; The word "health" also means "production", which shows that the incense burner peak is always misty. Through this kind of teaching, students not only understand the superficial meaning of language and writing, but also make them realize the deep meaning and emotional color of language and writing.
3. Use multimedia computer to stimulate students' writing will.
In composition teaching, we will find that many students are afraid of writing. When writing a composition, they often knock on their foreheads, frown and bite their heads, so they can't write for a long time. Even if it is written, it is still a few words, and there are many mistakes in sick sentences. Therefore, in teaching, we can choose audio-visual media to create scenes, strengthen students' emotional experience and stimulate students' interest in writing. The ancients said, "The knower is not as good as the doer, and the knower is not as happy as the musician." With interest and the desire to write, they can write attentively, thus improving the teaching effect of composition.
