Traditional classroom teaching is often criticized for its inherent weaknesses. However, in the foreseeable future, classroom teaching will still be the main way of school teaching activities. The rapid development of information technology has promoted the overall reform of education from purpose, content, form, method to organization. It is absolutely necessary for teachers who stand in the front line of education to re-understand the teaching process. The Outline of Basic Education Curriculum Reform (Trial) points out: "Vigorously promote the universal application of multimedia information technology in the teaching process, promote the integration of information technology and subject courses, gradually realize the changes in the way of teaching content presentation, students' learning methods, teachers' teaching methods and teacher-student interaction, give full play to the advantages of information technology, and provide a colorful educational environment and powerful learning tools for students' learning and development. "It can be seen that using modern information technology and giving full play to the unique function of information technology-assisted teaching are important ideas for teachers to improve classroom teaching. In order to use information technology reasonably and effectively in teaching, we first need to fully understand the role of information technology in classroom teaching.
First, the use of information technology to change the traditional teaching methods
The realization of good teaching effect in classroom teaching depends on advanced teaching media to help students make various learning reactions. In the traditional teaching mode, teachers' teaching activities are limited to a textbook, a blackboard and a simple slide. Dull and boring, students' initiative and creativity can not be fully exerted. After the introduction of multimedia information technology into teaching, it is like a spring breeze, which promotes the transformation of our educational concept and mode, enables our teachers and students to enjoy high-quality educational resources and cutting-edge teaching resources, and brings opportunities to the reform and development of basic education. It has completely changed the traditional education and teaching mode and liberated teachers from heavy repetitive work.
Second, the use of information technology to strengthen the leading role of teachers
After information technology enters the classroom, in classroom teaching, students are the main body, teachers change the traditional teaching methods, and guide students to take the initiative to acquire knowledge by using learning materials and teachers' help in certain situations. The teaching method of information technology has replaced the daubing of chalk on the blackboard and turned into exquisite pictures and video materials to be displayed on the screen. Students create situations in intuitive feelings, and experience language as a flesh-and-blood figure enters their thinking, participates in students' understanding and appreciation, collides with the protagonist's thoughts and feelings, and realizes emotional communication. Classroom teaching content is richer and more vivid, creating teaching scenarios, mobilizing students' life accumulation and inducing students to actively participate in the learning process. All this is the result of teachers using information technology to assist teaching, which further embodies the leading role of teachers. For example, when the teacher teaches the text "Weighing Elephants", he plays the courseware in time according to the content of the text, so that students can form exactly the same pictures or things in their minds. In addition, modern information technology provides a broader space for teaching, and teachers learn from each other through resource sharing, which plays a better role in providing students with learning resources and helping students solve difficulties. When preparing lessons, teachers can first enter keywords, search relevant information on the Internet, and make courseware by classification. In the process of guiding students' learning, you can use the mouse to call it up quickly as needed, which is convenient and fast. Students can study according to their own needs or interests. Only in this way can students' initiative be truly realized, and teachers have truly become students' helpers and promoters. In the teaching process, teachers guide students to broaden their horizons. With the accumulation of a large amount of materials, students really enliven the classroom atmosphere and stimulate their awareness of actively acquiring knowledge. It fully embodies the leading role of teachers.
Third, the use of information technology is conducive to improving students' interest in learning and invigorating the classroom atmosphere.
Interest is the best teacher. Good interest brings good learning motivation, but not every student has good learning interest. Curiosity is the nature of students. They are interested in new things and things they know but have never seen. To stimulate students' enthusiasm for learning, we must meet these needs. However, traditional teaching and many current teaching are carried out in strict accordance with the syllabus, which closes students in boring textbooks and monotonous classrooms, completely isolating them from rich resources and reality, resulting in a decline in students' interest in learning. Integrating multimedia information technology into the teaching classroom, using the characteristics of multimedia information technology, such as illustrations, audio and video synchronization, and dynamic and intuitive images, we can create various situations for students, effectively reproduce the considerable attributes of physical objects, make students perceive the artistic effects of things, form vivid pictures in their brains, create certain scenes, and make students feel immersive, so as to truly enter the role and experience emotions. So as to effectively mobilize the participation of students' various senses, stimulate students' strong desire for learning, stimulate their learning motivation and interest, help to create a relaxed classroom atmosphere, let students sort out their learning ideas with vivid pictures, enter the same realm as the author, and thus understand the main idea of the text. For example, Lin Hai is a beautiful text describing the Daxinganling Mountains. Teachers can make courseware reflecting the scenery of mountains, forests and flowers in Daxing 'anling in advance when explaining paragraphs, so that students can witness endless green forests with their own eyes on the screen. The rolling mountains are like rolling waves. In the text, "Everything is green when you look around." "Lin Hai" and other contents can be easily solved. With the sweet explanation, the students saw the snowflakes flowing in the video, and the trees pulled out new branches and grew young leaves. Look at the laughter of lumberjacks and the hard work of tree planters. Galloping trains continuously transport timber to all parts of the country. At this point, with a little help from the teacher, students can understand the general idea of this text: it is written that Daxinganling cannot be separated from the construction of the motherland. Really understand the meaning of the word "rejuvenating the country and securing the country". When the teacher reasonably shows other designs of Daxinganling scenery, students will sincerely feel that Daxinganling is indeed a huge treasure house. Therefore, the language in the text has become the words that students are eager to express. Faced with the teacher's questions, the interest in learning arises spontaneously, and the classroom atmosphere is active. For another example, when the Soviet Union published two ancient poems, Happy Little Shepherd Boy, a teacher showed pictures with courseware. The shepherd boy rode on the back of the cow and sang happily.
Teacher: (emotionally) Look, listen, the little shepherd boy is riding on the generous back of the cow. He rocked and rocked as if he were sitting in a cradle. Really comfortable! In the Woods, flowers are laughing, the wind is blowing and butterflies are flying. How beautiful! How happy I am! The little shepherd boy couldn't help singing loudly, and the song flew out of the jungle. Let's read these two lines.
