Multimedia teaching means that in the teaching process, according to the characteristics of teaching objectives and teaching objects, modern teaching media are reasonably selected and used through teaching design, and organically combined with traditional teaching methods, * * * participates in the whole teaching process, and acts on students with various media information to form a reasonable teaching process structure and achieve the best teaching effect. Multimedia is an indispensable equipment concept in modern education, such as computer, projector, slide show, booth, video, radio, film, electronic whiteboard, computer and so on. Using modern educational theory and technology, the theory and practice of teaching modernization are realized through the design, development, application, management and evaluation of teaching process and teaching resources.
The function of multimedia teaching equipment in teaching;
1, improve the efficiency of knowledge teaching
The effective amount of knowledge transfer per unit time is an important index to evaluate the efficiency of classroom teaching. In classroom teaching, students mostly use multimedia instead of traditional blackboard writing, wall charts and slides, and teach in spoken English. This method is relatively inefficient because it is abstract and needs to leave students a long time to digest and understand. Multimedia has the function of integrating graphics, audio-visual and animation, and its expression is more direct and vivid, which is convenient for students to understand and master on the spot. Therefore, in classroom teaching, we should make full use of this function of multimedia, and make some abstract theories concrete and visualized by making text textbooks into multimedia; Display some text descriptions with corresponding icons; Show some long-term and slow evolution results through animation; Demonstrate some working processes through images, so that students can easily understand and master what they have learned, so as to learn as much knowledge as possible in unit time.
2. Enhance the effect of interactive discussion.
Students' understanding of what teachers teach is another index to evaluate the quality of classroom teaching. In order for students to fully understand what they have learned, it is necessary for teachers to discuss and interact with students and students. Some teachers put aside multimedia technology when organizing interactive seminars, and still do it through gestures or language. This kind of interactive feedback has less information and low feedback efficiency. Multimedia has the advantages of large amount of feedback information and strong interaction. Therefore, teachers should make full use of this advantage in organizing discussions, feed back students' different understandings of the same problem through multimedia, guide them to compare from different sides, and analyze and demonstrate the results, so that they can consciously form a certain point of view and reach a consensus, so as to understand and master knowledge imperceptibly. For some antagonistic subjects, students can also play and rotate different roles, and use multimedia to perform deduction step by step, so that students can deepen their understanding of knowledge in multi-angle and multi-directional interaction.
3. Improve the quality of situational induction.
It is not enough to learn and understand knowledge, but also to enable students to use knowledge. In order to achieve this goal, students often need to be induced by some situations in teaching. Inductive teaching is generally carried out by assigning homework. Because of its weak sense of reality and fixed routines, it can't guide students to think and deal with what they have learned, so the quality is not high. Multimedia has intelligent characteristics such as simulating reality and scene simulation. Therefore, we should give full play to this advantage when inducing situations. By setting relevant knowledge into some situations and scenes, students can form judgments and operate according to their own understanding, and these situations and scenes can be presented interactively with the operation process, so as to guide students to apply what they have learned in specific operations, thus improving their knowledge application ability.
