With the development of the times and the progress of science and technology, modern educational technology is constantly improving. One of the greatest achievements of human science and technology in the 20th century-computer multimedia technology and network technology have been introduced into the education and teaching process. Students read not only words and pictures, but also a large number of audio books, a large number of animations and a large number of video materials.
With its distinctive teaching characteristics, rich teaching resources and vivid situations, it fully mobilizes students' subjectivity, makes students truly become the subject of information processing and the active builder of knowledge in the learning process, and becomes the technical basis for reforming classroom teaching mode, cultivating students' innovative ability and autonomous learning ability, and realizing educational modernization. Our school began in 1997, and multimedia has been widely used in teaching. Here are some of my experiences.
First, it can fully mobilize students' emotions and stimulate their interest in learning.
Students' yearning for learning, good interest and motivation, and happiness and enjoyment in learning activities are all the goals pursued by our teachers in classroom teaching. However, interest and motivation are not innate, but arise from the novelty and uniqueness of external things to meet the needs of students to explore psychology.
In classroom teaching, the media is the carrier of teaching information and the tool and means to transmit information. Its function is not only to convey the teaching content, but also to change the traditional teaching methods and learning methods, adjust the classroom atmosphere, create learning situations and stimulate learning interest.
Cultivating students' learning motivation and interest is one of the important tasks of school education. Interest is the tendency of people to try to understand something or like an activity. The role of learning interest is enormous. Regarding the relationship between teaching and learning, Confucius said: Knowing is not as good as being kind, and being kind is not as good as being happy.
Zhu in the Southern Song Dynasty also pointed out that if you are not happy, you will not learn. Piaget, a famous educator, said that children are not passively stimulated by knowledge or environment, but active people, and their activities are dominated by interest.
Interest is the best teacher, and the use of multimedia can stimulate students' interest in learning more easily, so that students can experience and understand knowledge under the guidance of strong interest. For example, in the lesson "Little Wolf Looking for Mom", we should understand the difference between three words: face up, catch up and swim across. Teachers alone cannot make students understand. Moreover, this knowledge point is a bit boring for junior students, and students' interest in learning is not high, so the teaching effect is naturally not good.
It is much easier to use multimedia. A few interesting animations, coupled with the teacher's proper explanation, can make students feel happy, and at the same time, the difference between these three words can be easily solved, achieving twice the result with half the effort.
The advantage of multimedia CAI courseware is that it can synchronize intuitive media information such as words, pictures, animations, sounds and images. It is impossible for other teaching media to display related words, images or animations on the same screen at the same time. In teaching, if we can make full use of this advantage, we can change abstraction into intuition, change static into dynamic, and effectively complete teaching tasks by showing students the teaching situation.
In classroom teaching, the proper use of modern educational technology is the best way to create situations. For example, there are two knowledge points in the article about eclipse: the change of eclipse and the reason of eclipse, especially the reason of eclipse, which is difficult for students to understand. Multimedia is used to naturally introduce students into the scene.
It not only turns abstract knowledge into vivid pictures, but also makes students have a strong interest in this natural phenomenon, and also makes them have the idea of wanting to learn and loving learning. They can perform easily and have the attitude of a small scientist.
Second, it can broaden the space of students' positive thinking and cultivate innovative spirit.
Today, when quality education is advocated, teachers' teaching is by no means to restrain children's thinking space, on the contrary, it is to encourage them to expand their thinking space, that is, to think in other's shoes. Present the thinking process, provide rich perception and representation, form a dynamic thinking field, build a bridge for students to realize the leap from concrete perception to abstract thinking, and cultivate innovative spirit.
The best way to achieve this goal is to use multimedia. For example, in the article "Weighing Elephants", students saw the four steps of Cao Chong's weighing elephants through multimedia. Through the pictures of these activities, students not only understand and master these steps, but also sprout new ideas.
A child said, "Teacher, I don't think Cao Chong's method is good enough, because the stone is very heavy, and it is not only time-consuming and laborious for soldiers to move around, but also not necessarily accurate. I think we can let the soldiers get on the boat one by one until the lines are drawn. Then let the soldiers report their weight ashore. Isn't that the weight of an elephant? This saves time and effort. "
On the spot, all the teachers and classmates admired him. Call him? Quot saicaochong. It can be seen that multimedia has really played an inestimable role in expanding children's thinking.
Third, it is conducive to optimizing the classroom teaching structure.
In the traditional teacher-centered teaching method, the teacher is the giver of knowledge and the student is the receiver 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, whether teachers can clearly and thoroughly explain the teaching materials is no longer an important criterion for classroom teaching evaluation.
Under the information education environment, the role of teachers has undergone fundamental changes, from the front desk? Quot: As a backstage guide, it is important to prepare lessons in advance, which requires teachers to delve into the teaching materials, devote more energy to providing students with rich and orderly learning materials, create the best learning situation for students, mobilize students' interest, enthusiasm and initiative in learning, and organize students to think and explore in the process of in-depth learning.
Let students study happily and consciously in a lively atmosphere, and let students give full play to their enthusiasm and initiative.
The teacher said that the teaching time for students to listen is gone forever. A teacher is more of a guide and consultant, a participant in exchanging opinions, rather than an arbitrary authority based on students' passivity and ignorance. So how to achieve this effect? Naturally, we must rely on our multimedia to help.
I watched a great Chinese class "Grey Bird". The teacher made full use of multimedia. The whole class only asked three questions. The students talked a lot and discussed a lot. In this process, the teacher also praised and affirmed the students with multimedia. Teaching is lively, harmonious and enthusiastic.
What is even more surprising is that with the influence and help of multimedia, the theme of "Jade Bird" has sublimated students to the realm of man and nature, and students' subjective consciousness has been fully exerted. To achieve this effect, multimedia is indispensable.
Fourth, provide more updated and broader knowledge points and broaden your horizons.
In traditional teaching, teachers rely on textbooks, especially science and social studies. Due to the limited materials provided by the textbooks and the limited time for a class, as teachers, students can only accomplish their tasks by mastering a few knowledge points. Imagine how such learning can broaden their horizons and gain more updated and broader knowledge points.
How do we meet the challenges of the information age? However, the application of multimedia immediately changed this phenomenon obviously.
For example, teaching social studies class "Japan", the traditional teaching is to tell the geographical location of Japan with a wall chart, read textbooks to understand some situations in Japan, and make your teacher drool, but students still can't lift their spirits. Why? The hearing is empty, seeing is believing! Using multimedia, students' energy is completely different, and the geographical location can be displayed from small to large, so that you can see it clearly.
When it comes to Japan's economy, we can see the prosperity of Tokyo: when it comes to the symbol of Japan, we can see the majestic posture of Mount Fuji and the beauty of cherry blossoms; Speaking of Japanese customs, you can see girls wearing kimonos, characteristic umbrella dances and highly respected sumo wrestling; Speaking of Japanese snacks, you are dazzled and drooling. ...
You can have a panoramic view of Japan in just 40 minutes. The students are not satisfied, which not only increases their knowledge and broadens their horizons, but also makes them fall in love with this subject from now on. Anyway, the role of multimedia is really different!
In a word, multimedia-assisted teaching is a new and effective teaching method, but it requires us educators to make a lot of high-quality multimedia teaching software to promote the development of teaching to modern teaching methods and make our due contribution to improving students' ability, implementing quality education and improving teaching quality.
