On the main role of the media in the information-based teaching mode are as follows
With the development of the times and the progress of science and technology, modern educational technology means also continue to improve, one of the greatest achievements of human science and technology in the twentieth century - computer multimedia technology and network technology was introduced into the education and teaching process, the students' reading Objects not only text and pictures, but also a large number of audio books, a large number of animations, a large number of video materials.
It is with its distinctive teaching characteristics, rich teaching resources, vivid image of the situation, fully mobilize the student's subjectivity, so that students in the learning process really become the main body of information processing and knowledge of the active constructor, and become a reform of the classroom teaching mode, cultivate students' creativity and independent learning ability, to achieve the technological basis of the modernization of education. Our school in 97 years, multimedia has been widely used in teaching, the following talk about some of my experience.
One can fully mobilize students' emotions, stimulate interest in learning
Students' desire to learn, have a good interest and motivation, in the learning activities to obtain happiness and enjoyment, are not our teachers in the classroom teaching in the pursuit of the goal. However, interest and motivation is not inherent, but through the novelty and uniqueness of the external things to meet the needs of students' psychology of inquiry and caused.
In classroom teaching, the media is the carrier of teaching information, is a tool and means of transmitting information. Its role is not only used to transmit the content of the teaching, but also to change the traditional teaching methods and learning methods, regulating the classroom atmosphere, create a learning environment, stimulate interest in learning.
The cultivation and development of students' motivation and interest in learning is one of the important tasks of school education. Interest is the tendency of people to strive to know something or love a certain activity. The role of interest in learning is enormous. In the relationship between teaching and learning, Confucius said:The one who knows is better than the one who is good, and the one who is good is better than the one who is happy.
Southern Song Dynasty Zhu Xi also pointed out that: teaching people do not see the interest, will not be happy to learn. The famous educationist Piaget said that children are not passive to receive knowledge, not passive to receive environmental stimuli, but has the initiative of the people, his activities by the domination of interest.
Interest is the best teacher, the use of multimedia is more likely to stimulate students' interest in learning, so that students are guided by a strong interest in experiencing and understanding knowledge. For example, in the lesson of "The Little Mantis Looking for Mother", it is necessary to understand the difference between the three words "welcome", "chase" and "swim". If you rely on the teacher's words alone, the students will never be able to understand them. Besides, this knowledge is a bit boring for the lower grades, and the students' interest in learning is not high, so the teaching effect is naturally not good.
Using multimedia, it is much easier, a few interesting animation, coupled with the teacher's appropriate explanation, the students in the look at the happy at the same time, the difference between the three words will be solved, to achieve the effect of twice the result with half the effort.
Multimedia CAI courseware with text, pictures, animation, sound, images and other intuitive media information can be synchronized advantages. On the same screen at the same time to display the relevant text, images or animation, which is other teaching media can not be achieved. Teaching, if you can make full use of this advantage, change the abstract into intuitive, change the static into dynamic, by showing students the teaching situation, effectively complete the teaching task.
In classroom teaching, the appropriate use of modern educational technology is the best way to create a situation. For example, in the article "watching the lunar eclipse", there are changes in the lunar eclipse and the cause of the eclipse of the two knowledge points, especially the cause of this scientific knowledge is not easy for students to understand, the use of multimedia, the students were naturally introduced to the scene.
Not only does the abstract knowledge become an image of the picture, but also makes the students have a strong interest in this natural phenomenon, but also makes them want to learn the idea of learning, perform with ease, and have a small scientist's frame.
Two, can more widely expand the space of positive thinking, cultivate the spirit of innovation
In the promotion of quality education today, the teacher's teachings are not to bind the children's thinking space, on the contrary, to encourage them to expand their own thinking space, that is, different thinking. Presentation of the thinking process, to provide a rich perception, representation, constitute a leaping thinking field, for students to realize the leap from concrete perception to abstract thinking to build bridges, cultivate the spirit of innovation
The best means to achieve this purpose is the use of multimedia. For example, in the article "Weighing the Elephant", students saw the four steps of Cao Chong weighing the elephant through multimedia. Through these moving images, students not only understood and mastered these steps, but also developed new ideas.
One child said, "Teacher, I think Cao Chong's method is not good enough, because the stones are very heavy, and it is not only time-consuming and laborious for the soldiers to move them around, but also not always accurate when they are weighed. I think we can just let the soldiers get on the boat one by one until the place where the line is drawn. Then let the soldiers go ashore and report their weights, and then add up the weight of the elephant, right? That would save time and effort."
On the spot, the teacher and his classmates were very impressed with him, calling him ?quot;Sai Cao Chong. It can be seen that multimedia does have an inestimable role in expanding children's thinking.
Three, is conducive to the optimization of the classroom teaching structure
The traditional teacher-centered delivery method of teaching, the teacher is the transmitter of knowledge, the students are the recipients of knowledge, the basic process of learning is the student perception, understanding, consolidation and application. Teachers on the podium to tell, demonstration, demonstration, students accordingly absorb, memorize, store, circle the key points in the classroom, repeated copying and recitation after class.
It has been proved that the biggest drawback of this kind of teaching method, which aims at test-taking ability, is that it stifles children's creativity and innovative spirit
In the information-based education environment, it is no longer based on whether the teacher is able to explain the teaching materials in a clear and understandable way and analyze them in depth and thoroughly as an important criterion for the evaluation of classroom teaching.
Informationalized education environment, the role of the teacher has undergone a fundamental change, from the foreground ?quot: acting to the background of the guide, to put the main effort on the preparation of the lesson beforehand, which requires teachers to study the materials in depth. Put more energy into providing students with rich and orderly learning materials, creating the best learning situation for students, mobilizing students' interest in learning and enthusiasm, initiative, and organizing students to go deeper into the learning process to think about the inquiry.
To make students in a lively atmosphere in a pleasant and consciously active learning, so that students can maximize their enthusiasm, initiative.
The teacher speaks, students listen to the teaching era is gone. Teachers are more of a guide and counselor, a participant in the exchange of views, rather than built on the basis of student passivity and ignorance of the arbitrary authority. So how to achieve this effect? Naturally, it is again with the help of our multimedia.
I observed an excellent language class "Gray Sparrow", the teacher made full use of the multimedia, the whole class only raised three questions, the students said more, more discussion, in the process, the teacher also used multimedia to praise and affirmation of students, teaching anger and harmony and warm.
What's more surprising is that, under the influence and help of multimedia, the theme of "Gray Sparrow" allows students to sublimate to the realm of man and nature, and the students' subjective consciousness to the fullest extent. To achieve this effect, multimedia is a great credit.
Four, to provide more, newer, broader knowledge, broaden the horizons
Traditional teaching, teachers are dependent on the textbook lectures, especially in nature, society and other courses, due to the materials provided by the textbook is limited, a class of time is limited, as a teacher only to let the students master a few knowledge points on the completion of the task, imagine how the learning can let students broaden the horizons. The first step is to make sure that the students have a good understanding of the subject matter and that they have a good understanding of the subject matter.
How can we meet the challenges of the information age? However, the application of multimedia, immediately make this phenomenon has changed significantly.
For example, the teaching of social studies "Japan" class, the traditional teaching is the use of wall charts, talk about the geographic location of Japan, read the textbook to understand some of the situation in Japan, any teacher you talk about spit and fly, the students still can not raise the spirit, why? Hearing is not believing, seeing is not believing! The use of multimedia, the student's energy is completely different, geographic location can be changed from small to large display, so you can see clearly, clearly.
Speaking of Japan's economy, you can see the prosperity of Tokyo: Speaking of Japan's symbols, you can see the majesty of Mount Fuji, the beauty of the cherry blossoms, speaking of Japan's customs, you can see the young girls in kimono, quite distinctive umbrella dance and highly respected sumo wrestling: speaking of Japan's snacks, but also to let you see the dazzle, drooling --. ----
Short forty minutes, you can let you take in the whole picture of Japan, but also let the students can't get enough of it, not only increased knowledge, broaden their horizons, but also let them from now on fell in love with the subject. How is it, multimedia role is really different from the ordinary it!
In short, the use of multimedia to assist in teaching is a new and effective means and methods of teaching, but this requires us to produce a large number of high-quality multimedia teaching software for educators, prompting the teaching of the modern means of teaching to move forward to improve the ability of students, the implementation of quality education, improve the quality of teaching and learning to make their own due contribution.
