Discussion on the Advantages and Disadvantages of Multimedia

Paper Keywords: multimedia teaching the main principles of teaching strategies
Abstract: With the era of progress, technological development, more and more schools, institutions, and individuals begin teaching using multimedia technology. However, the over-exaggerated the capabilities of multimedia technology, ignoring the limitations of his own of that teacher in the teaching process makes the dominance shift occurred. This paper analyzes the multi-body techniques in the teaching process to seek the advantages and limitations, and these problems should sound reasonable approach.

Multimedia is the use of computers, projectors and related office applications and other modern means of teaching the process of teaching a series of abstract, through audio, video, intuitive way to show to students of modern teaching aid in a good teaching and improve learning efficiency.

First, the multimedia teaching
1, the more vivid information, driving more efficient teaching. Multimedia courseware is a collection of various types of information as one of the efficient vector, including language, text, still images and video. These novel sensory stimuli can bring students directly intuitive sense of feeling and image, fully stimulate the students interest in learning, stimulate the desire of students, the students changed the previous situation of passive acceptance of knowledge.

2 and improve the coherence of knowledge. Multimedia teaching is the ability to review any past knowledge, writing on the blackboard, after all, is limited, a lesson or a course of information they involve far side of the board can accommodate, so some knowledge on each class were reviewed only by the recollections of when to emphasize that the coherence and effectiveness will be affected, and multimedia teaching to completely solve this problem, it can stop the cycle of play, review, summary , emphasizing the point of knowledge to focus and strengthen student learning and thus to achieve continuity of learning.

3, increasing the amount of information per unit of time the classroom to improve learning efficiency. In the teaching process, the use of multimedia technology can greatly save the time of writing on the blackboard, so that teachers can make the internal energy per unit time passing more knowledge to the students, and greater student receiving information, improve learning efficiency.

4, is conducive to teaching re-breaking and difficult. The advantage of multimedia technology in its presentation in real life can be difficult to duplicate in a short time or is difficult to demonstrate some of the experimental results, the use of multimedia, we can show from all angles, three-dimensional graphics, can make it difficult to understand abstract concepts into concrete images can be observed, graphics, even with the appropriate video and audio to a number of experimental demonstration of the dynamic process of change, can also stages a number of important steps in the conduct of experimental demonstration Enlightenment with the instructor in a timely manner to explain. can make students more easily understand and grasp, heavy and difficult to break through the school.

5, is conducive to the efficient utility of resources. The traditional teaching mode is still very dependent textbooks, instructor, although many have access to new knowledge, however, to be integrated into the knowledge of traditional teaching, it is very difficult. And For the modern undergraduate teaching, many of expertise in rapid, purely relying on textbook teaching is not enough. So we must change our teaching ideas. should aim at training students in the spirit of innovation and participation goals leading teaching. and this premise is that classroom teachers must be as much as possible to collect information on the professional and timely screening to multimedia content up. can be said that the future of Education will be an Education without boundaries, Whether teachers or students can browse through the power of networking to the subject matter of the world in the foreseeable future, the global sharing of teaching resources will become an irreversible trend.

Second, to carry out the problems in multimedia teaching
1, over-reliance on the machine, and weakens the classroom communication between teachers and students. Multimedia teaching in its expression to the image of a lot of abstract concepts and the limited time to show a lot of information, but it is in language, gestures and facial expressions, etc. on the expression does not have advantages in multimedia teaching process, many teachers for a long time, or even a whole class front of a computer mouse operation to explain the knowledge. students can only hope that their claims are often not reflected in its people, the whole class is like a report of the meeting, no passion, no exchanges. Education should be a two-way process, not only have a classroom teacher for the dissemination of knowledge, but also with the timely feedback on student learning. and more importantly the teachers and students between eye contact from time to time. However, these difficult to show in the multimedia teaching. reposted elsewhere in the Research Papers Download http://www.hi138.com 2, courseware production level and presentation quality is generally not high. At present, many teachers To save time, are downloaded directly from the courseware, or with the use of multimedia teaching courseware, courseware and teaching materials to match though, but this kind of teaching is tantamount to full accordance with the book by chapter for justice, without any idea of ​​their own . This is for teachers to enhance their own literacy is very limited. There is also a direct copy of the teachers to other teachers simply courseware. This result is due not involved in the production, resulting courseware is not well suited to the needs of teachers, the ultimate impact of teaching effect.

3, the content is too fancy of teaching. Multimedia courseware can be rich and varied styles, the framework can be varied, but whether the background image animation or music classes are content to do a supplement, which is absolutely not change . But, many teachers in the school Shique just overlooked this point, through the fancy technology with too much additional information and irrelevant information, making the primary and secondary school, regardless of the content changes, so hard to make students concentrate to absorb useful information, a class after the students are just feeling down and stuffed a lot of head stuff, but these things have absolutely no contact between the or logic, and then know what to do. teachers, the most blindly seeking variety of courseware, but forget to provide multimedia services to students, in the learning process must have a main line running through them, and now the situation is the subject of the seemingly active atmosphere, but not a very good learning. Courseware must be drawn so appropriate, properly, should not be too fancy.

Third, the multimedia teaching suggestions for improvement
1, multi-media combination of teaching and traditional teaching. We in the use of multimedia teaching, should be an appropriate combination of blackboard, body language and eye contact, then grasp the rhythm of the classroom to enhance the interaction with the students. The only way to fully mobilize students enthusiasm, stimulate students intellectual curiosity, ability to inspire students to think. teachers in the lecture process, not over-dependent production of good courseware, but should have a clear idea of ​​smooth constraints courseware without conditions, according to student's actual learning to adjust the relative progress of teaching, strengthen the exchange of learning among students, interactive teaching, rather than to passively accept information for students.

2, establish a scientific evaluation mechanism for multimedia teaching. Multimedia teaching and traditional teaching to play the role of a pair of complementary, multi-media teaching not and can not completely replace traditional teaching methods. It can work as a teaching aid. But Now many teachers to link with the new curriculum, unplanned, or excessive use of the multimedia teaching, so that the process of expanding the multimedia teaching some of the pitfalls. in order to better play the advantages of multimedia, you must study in depth the process of teaching professional courses, supporting the design of appropriate courseware, using multimedia technology to make progress with the teaching to match. Meanwhile, the concept of teaching should be updated to strengthen the training of teachers, the times, a more scientific evaluation system for multimedia teaching.

3, guide students to make good use of courseware. Courseware is an excellent instructor, after the work has been carefully prepared, students should make full use of multimedia courseware for review after class, so as to fully digest and understand the classroom knowledge and to improve learning efficiency. Even the classroom After-school teachers can find some additional form of knowledge to share courseware to the students for their after-school use.

IV Conclusion
Overall, the multimedia teaching of modern information technology is booming in the larger environment developed a new teaching model, but not to say that this model can have completely abandoned the traditional teaching methods. Measure of a teaching The quality of teaching methods should be based on whether the practice of teaching to meet the needs-based. in the teaching process, whether traditional or multimedia teaching model teaching methods are just a means of teaching about teaching it, the purpose is to better impart knowledge, they are a complementary, the relationship between each other. in the teaching process, teachers should teach the object based on the specific circumstances of the rational use of modern multimedia technology, and combined with traditional teaching methods, and thus achieve the most optimal teaching. transfected affixed to the Research Papers Download http://www.hi138.com
