Teachers must have modern teaching ideas when choosing multimedia teaching methods, and must have? Student-centered? At the same time, focus your time and energy on the key and difficult breakthroughs in each class. The following is the model essay of relevant papers that I have compiled for you, hoping to help you. For details, please visit (www.oh 100.com/bylw).

This paper studies the application of modern multimedia in science teaching from four aspects: purpose, necessity, classroom capacity and combination with other teaching methods, so as to make science class more exciting and achieve the best effect.

Keywords: multimedia; Science; Teaching application; teaching means

With the development of multimedia technology, multimedia technology is deeply loved by teachers and students in classroom teaching because of its illustrations, dynamic and static combination and excellent audio-visual performance. Therefore, only by combining the new curriculum with traditional teaching and modern technical means can teachers give full play to their powerful advantages. And multimedia teaching courseware should not be simply regarded as? Electronic blackboard writing? It only exists to pursue fashion and show off, and such multimedia teaching effect will not achieve satisfactory results. Therefore, the application of multimedia technology in teaching should be selected according to the teaching content, and at the same time, the necessity and purpose of teaching should be considered, and the courseware content should be appropriate and just right.

First of all, to achieve a clear purpose.

Teachers must have modern teaching ideas when choosing multimedia teaching methods, and must have? Student-centered? At the same time, we should concentrate our time and energy on the breakthrough of the key points and difficulties in each class. Don't cover all the knowledge points, just tell the problems that are really difficult to explain clearly with the unique advantages of multimedia, so that students can really hear clearly and understand. For example, in the second volume of "Teaching Third Grade Science"? Animals? Friends of mankind? When, in order to make a better breakthrough for students to understand? Why are animals friends of human beings? What are the main reasons why animals are endangered? I chose to use multimedia teaching method to implement teaching. Because I consider that different students may like different animals and have different understandings of how people make friends with them, I regard courseware design as selective. In other words, students can choose different animals to understand according to their own preferences, and teachers don't have to introduce every animal to all students. At the same time, when dealing with difficulties, considering that each animal is facing different reasons for extinction, the courseware has also done similar treatment, and students can choose to understand and master according to their own interests.

Second, consider the necessity of using multimedia.

I think we should first make clear which classes need to use multimedia and which classes don't, and we must not use it blindly. For some practical contents, students should be allowed to operate by themselves and experience and think in the process, so that the effect will be more impressive than just putting a few animations. Here we must correct a wrong idea: that is, only the teaching process using multimedia teaching is modern teaching. Multimedia technology is only an auxiliary means in the teaching process, and it is not used in every class. If unnecessary classroom teaching becomes necessary, it may appear? Gild the lily? Otherwise, the teaching effect will not be achieved. Nowadays, when many teachers use multimedia teaching, they just display the classroom knowledge points on the big screen, and then look at the screen with a microphone to give lessons to students. Will the whole class stay like this? Report? In the form of multimedia courseware, it just becomes an electronic blackboard, which is a kind of multimedia classroom teaching for the purpose of using multimedia. If multimedia is not used according to teaching needs, there will be no good teaching effect. Therefore, we should properly choose multimedia according to the needs of teaching content, and really give full play to its advantages, so that it can better help teachers and students to carry out effective teaching. Like teaching? Earth and us? In one class, in order to let students know what kind of human activities will destroy the soil, if students can be organized to go out for investigation, the teacher can not use multimedia, because the effect obtained by personal investigation is much better than using multimedia. However, if you can't go out for investigation, you can use multimedia teaching to show students relevant information and draw a conclusion.

Third, the classroom capacity should be appropriate.

The use of multimedia teaching presents a large amount of information and a fast presentation speed, which may lead teachers to unconsciously speed up classroom teaching, lead students' thinking to be out of sync with teachers' explanations, and fail to keep up with teachers' rhythm, or lead students' classroom notes to be incomplete because of the fast presentation speed of information, which will affect their subsequent review and consolidation. If the pace is too fast, students' understanding of knowledge will be insufficient, incomplete and profound. On the other hand, if the pace is too slow, students' thirst for knowledge will not be satisfied, their attention will be distracted and their interest in learning will be lost. Therefore, when applying multimedia teaching, teachers must ensure that the classroom content is moderate, the courseware picture is concise, the content is concise, the focus is prominent, and the color contrast of the picture should also conform to the students' visual aesthetics. Like what? Do you know about boats? A class contains a lot of knowledge. Before learning the first part, students need to have the basic concepts, basic shapes and various types of ships in order to complete the teaching objectives and rank the following ships according to the development order of ships? .

Fourth, cooperate with other means.

When using multimedia technology in teaching, teachers must grasp the opportunity of using various media and correctly handle the relationship between multimedia and traditional teaching methods, such as chalk, blackboard, teaching AIDS and language expression. In particular, we should consider the time factor and correctly handle the opportunities of using multimedia explanation, blackboard writing and teacher-student communication in class. Only with the organic cooperation of various teaching methods and tools can we arouse students' active participation in various senses and feel the vividness of teaching.

Verb (abbreviation of verb) conclusion

In a word, it is the general trend that modern multimedia technology is widely used in classroom teaching. The application of multimedia means plays a very important role in stimulating students' interest, and proper application of multimedia in science classroom teaching will get unexpected results. However, we should remember that multimedia courseware, no matter how wonderful it is designed, is only a means. It can't replace teachers' emotional input, language appeal and teacher-student interaction. Only by complementing each other and integrating these factors organically can we really serve the classroom, the teachers and the students, and make our science class colorful and achieve the best results.
