How to use multimedia teaching to improve the effectiveness of classroom teaching

It has been proved that a good multimedia courseware should make full use of the principles of contemporary cognitive psychology, so that students can obtain relevant information through multiple sensory organs, improve the efficiency of examination and dissemination, and enhance the enthusiasm, vividness and creativity of teaching. The application of multimedia teaching courseware in classroom teaching reflects this point and achieves the purpose of optimizing classroom teaching. Its performance is as follows:

1, the use of multimedia teaching courseware lectures, can be abstract for the image, become boring for the lively and interesting, enhance the teaching process of fun and credibility, is conducive to cultivate students' interest in learning, stimulate the desire to learn.

The American educationist Bruner said: "The best stimulus for learning is the interest in the material being studied". China's educator Confucius also said, "Those who know are better than those who know well, and those who know well are better than those who know with pleasure." The power of interest is enormous. There are a large number of concepts and principles in the teaching materials of ideological and political courses, which are very abstract and boring to explain with traditional teaching methods. At the same time, there are many concepts, principles, due to the lack of perceptual knowledge of the students, but also makes the teacher's explanation in the minds of students lack of credibility, it is difficult to stimulate students' desire for knowledge and interest in learning. Multimedia courseware using graphics, images, sound, three-dimensional animation technology and other integrated means to a large number of audio-visual information, high-tech means of expression to impact on the excitement of students' thinking, coupled with virtual reality technology, will be the abstract issue of visualization of the boring text narrative becomes lively and interesting, so that the teaching content is rich and colorful, vivid image, thus enhancing the credibility of the teacher's explanation. For example, in the case of the analysis of how to deal with traditional culture on the introduction of the Minnan children's song "sky black black", beautiful music, with the teacher's explanation of concise language, stimulate the students' interest in learning, so that boring learning becomes easy and pleasant to learn, so that the students learn with great interest.

2, the use of multimedia teaching courseware instruction can enrich the teaching content, condensed essence of the material, expanding the teaching capacity.

Multimedia courseware into the classroom, the majority of political teachers can make full use of multimedia technology to capture the rich flavor of the teaching content to enrich and enrich the classroom teaching content, but also can condense the essence of the teaching materials, reproducing the typical historical scene, so that students in a few minutes across thousands of years of history, trekking across a wide variety of disciplines in the field of the effective expansion of the teaching capacity. Mouse click, the world's knowledge are converged on the screen at hand, rich in content and detail, the teacher "like a tiger with wings", students "like a fish in water" not only to emphasize the key points of teaching, breakthroughs in teaching the difficult points, but also to help students better understand and accept the content of the teaching, but also for the teaching of the synthesis of the creation of better conditions. For example, the use of multimedia teaching in the case of the material to realize the review and transfer of knowledge, from the fourth lesson of the third link to the content of the fourth lesson of the second, in the use of knowledge and cited General Secretary Hu Jintao put forward to set up and adhere to the "eight for the honor, eight for the shame of the" concept of socialist honor and shame of the content of the socialist honor and shame of the content of the socialist honor and shame of the students cite the phenomenon of the community or around them, and make a simple evaluation. The students were asked to cite social phenomena or examples around them, and to make a simple evaluation, so that the design not only reflects the times, but also avoids empty sermons; not only mastered the book knowledge, but also current affairs education, ideological and moral education.

3, the use of multimedia teaching courseware teaching is conducive to change the difficult to easy, simplified, highlighting the key points of the material, difficult to improve the efficiency of teaching.

Teachers accurately and reasonably deal with teaching materials, the arrangement of teaching methods, is to affect the quality of teaching, improve the efficiency of teaching an important factor, one of the important point is how to focus on teaching materials, difficult breakthroughs, in order to achieve students to understand the purpose of mastering the multi-media teaching courseware is to achieve the purpose of an effective means. Multimedia teaching courseware can be abstract and complex theories visualized to solve the key points of the material, difficult points. For example, in the study of the spirit of the nation and the spirit of the times, cited the 2008 Beijing Beijing Olympic Games mascot Fuwa, through the observation and introduction of the picture, the students at once on the development of socialist culture, combined with the spirit of the times creatively absorbed all the fruits of civilization, including the traditional Chinese culture, this focus on the knowledge of intuitive and profound understanding.

4, the use of multimedia teaching courseware can optimize the learning process, improve the quality of classroom teaching.

(1) Multimedia teaching courseware multi-angle, multi-level information stimulation, can strengthen students' memory and understanding of knowledge.

In ideological and political lessons, there are many concepts and principles that students need to understand and memorize. Too many, making it difficult for students to memorize; plausible concepts and make it difficult for students to clearly identify. Multimedia courseware sound, graphic combination of students' eyes, ears, hands, brain and other sensory organs are fully mobilized to strengthen students' memory and understanding of knowledge. At the same time, multimedia courseware allows students to y understand the various knowledge points, from local analysis of the intrinsic connection between the knowledge points, and then to the global synthesis, to facilitate the formation of a meticulous knowledge network structure, so that students are more likely to remember, understand and master the knowledge they have learned. For example, in the study of the spirit of hard work this knowledge point, I play the video about the thousand hands of the Goddess of Mercy, so that the students in the sensibility of the information stimulation, the spirit of hard work and the development of the times with this knowledge has a deeper understanding and understanding.

(2) The large-capacity information transmission of multimedia courseware and timely teacher instruction are conducive to the development of students' analytical and synthesizing abilities.

The process of students seeking knowledge is a process of gradually rising from perceptual awareness to rational awareness. Perceptual awareness can only be accumulated to a certain extent from the quantitative leap to qualitative change. If students lack sufficient perceptual knowledge, it is difficult to form a rational understanding of things and problems. The shortcoming of the traditional teaching method of ideological and political class is that it can not provide students with a large amount of perceptual knowledge in the classroom, while the multimedia courseware can enable students to obtain a large amount of perceptual knowledge in the process of using it because of its condensed content and great capacity. In the students to obtain a certain amount of perceptual knowledge, the teacher to explain the timely instruction, can promote students' understanding of things from perceptual to rational, from understanding the phenomenon of things to understand the essence of things, and cultivate students to analyze and synthesize the ability to think. For example, to explain the third grade, the fourth lesson of the "China is facing a serious environmental situation", play the current living environment and environmental problems in China's multimedia courseware, so that students in the playback and discussion of new knowledge, but also cultivate students to analyze the problem, problem-solving skills.

(3) Multimedia teaching courseware can expand students' knowledge and activate their potential creative inspiration.

Multimedia courseware effectively expands students' horizons, broadens students' knowledge, so that students learn more scientific knowledge conducive to innovation. The use of constantly updated multimedia computer technology to improve students' awareness of information technology, stimulate students' curiosity, aggressiveness and desire for knowledge, and enhance the students' sense of innovation. For example, when explaining the knowledge of the scientific and technological revolution, the video of the successful ascension of Shenzhou VI was played, and students were asked to discuss the issue, combine it with the theoretical knowledge in the class, and analyze and explain what is the fundamental reason for the success of the flight of the manned spaceship Shenzhou VI? What knowledge points of the textbook are embodied? Through the group discussion, encourage students to boldly seek new, broaden the students' horizons, enhance the students' sense of innovation, clever classroom classroom and social stage organic combination, so as to realize the knowledge, awareness, ability to lay a solid foundation for the goal of organic unity.

5, the use of multimedia teaching courseware teaching is conducive to play a leading role in teachers, improve the overall quality of teachers.

The use of multimedia teaching courseware for teaching, to the dull traditional teaching classroom brought a revolution, but also brought a refreshing feeling. At the same time, it also brings pressure and motivation to teachers. Teachers' activities will not be as before, solely by a mouth, a chalk, a blackboard or with a simple means of electronic teaching to complete, but the integrated use of a variety of media technology. In this way, the comprehensive quality of teachers put forward higher requirements: teachers should not only master the computer, especially the use of multimedia, but also to be able to use multimedia means of design and implementation of teaching, scientific selection and editing of teaching courseware, guiding students to use multimedia for learning and so on. The use of multimedia teaching courseware in the classroom, the traditional knowledge transfer teaching mode will be broken, the role of the teacher will be more into the core of the teaching activities, and then the leading role of teachers can also be fully realized.
