With the development of modern educational technology, multimedia, as a new teaching method, has been widely used in various scientific teaching fields. Multimedia classroom teaching has advantages that traditional teaching cannot match.

The use of multimedia-assisted teaching is conducive to deepening students' understanding of knowledge, and it is easy to give play to the main role of students. Foreign studies have shown that people can memorize 15% of the knowledge obtained from hearing through language; 25% of the knowledge obtained from vision; use sound and light synchronization equipment to combine hearing and vision, and can memorize 65% of the content. Political theory is generally abstract and boring. If teachers just explain monotonically, it is easy to suppress students' thinking, make their brains tired and distract them. When teachers teach new knowledge, if they can use multimedia teaching instrument technology to penetrate them, and use advanced computer multimedia tools such as computers, projectors, touch screens, electronic whiteboards, etc. to show students electronic courseware combining pictures, text, sound and images, then It can make the abstract and boring knowledge principles become easy to understand and concrete, and it is convenient for students to understand and master the content of knowledge, so as to achieve the effect of more with less.

Multimedia teaching equipment can display teaching content, display learning goals, and ask questions for reflection and discussion through screens. Students can read, think, discuss, and answer in a targeted manner. Multimedia provides students with learning conditions and answers in a timely and prompt manner. Judgment can maximize the student's main role, and teaching instruments promote students' active learning. At the same time, the use of multimedia-assisted teaching also facilitates timely feedback in the classroom, the transfer of knowledge, and the expansion of abilities, thereby cultivating students' creative spirit and ability.
The use of multimedia-assisted teaching is conducive to increasing the capacity of information in the classroom and speeding up the pace of classroom teaching.

Increasing the amount of information is an important condition for improving the quality of teaching. In the limited time of a class, teachers need to give full play to the role of multimedia teaching in this regard if they want to improve classroom teaching efficiency. As we all know, the timeliness and timeliness of politics classes are very strong; in modern society, the multi-faceted nature of information sources for teaching equipment makes students unsatisfied with the dry lectures and lectures in the classroom. The full use of multimedia means in politics teaching can broaden and deepen the knowledge of teaching materials, enrich teaching content, and enable students to obtain as much effective information as possible in a limited time.

In the information age of the knowledge explosion, how to speed up the pace of classroom teaching and effectively expand the capacity within a limited forty-five minutes is a problem faced by every ideological and political teacher. Multimedia can easily and quickly process information. Whether it is text, sound, or pictures, teaching instruments can be operated as needed. This breaks the traditional teaching mode of "one book, one board, and one chalk", greatly speeding up The pace of classroom teaching is not only limited to teaching materials, but also maximizes the integration of textbook-related content into the classroom, effectively expands classroom capacity, and achieves the characteristics of political classroom teaching that are perfectly and harmoniously linked to reality.
