Multimedia teaching has become an indispensable and important teaching aid to improve the teaching effectiveness of ideological and political theory courses. However, there are some problems in practical application, such as emphasizing form over content, emphasizing courseware over teachers and students, and emphasizing modernity over tradition.

? To solve the above problems, we should first improve the quality of multimedia courseware, and at the same time, we should combine multimedia teaching with traditional teaching methods, and pay attention to teacher-student interaction and emotional communication.

With the development of information technology, multimedia teaching has become an important means to promote educational informatization. Computer-centered multimedia teaching has changed the teaching environment of chalk and blackboard in the past, integrating vivid animated images, clear text annotations and beautiful sounds, bringing students into a new world of sound, image, picture and text, and greatly improving the teaching effect. However, multimedia teaching is not omnipotent, and there are also some problems in the application process. Different courses and chapters should choose whether to use multimedia teaching according to the actual teaching needs, and the actual effect of multimedia teaching will vary greatly due to the different course nature and teaching content. Especially for theoretical ideological and political theory courses, the key lies in how to organically combine modern teaching technology with the nature and content of the course to effectively improve the teaching effect. This paper analyzes the present situation of multimedia teaching in ideological and political course in recent years. Generally speaking, the application of multimedia teaching technology is still very obvious in improving the effectiveness of ideological and political course teaching, but there are also some places that need to be improved and perfected in the specific application process.

First, the positioning of multimedia teaching in colleges and universities

Multimedia teaching refers to computer-aided teaching, that is, with the help of pre-made multimedia teaching software (courseware), teaching activities are carried out by computer. It refers to the process of using computers to comprehensively process and control media information such as symbols, languages, characters, sounds, graphics, images, etc., organically combine various elements of multimedia and display them on the screen or projection according to teaching requirements, and add sound coordination and human-computer interaction between users and computers as needed to complete teaching or training. With the application of multimedia education technology, teachers' teaching methods have undergone fundamental changes. As a brand-new teaching method, it integrates computer, projector, video recorder and tape recorder technology to form an operating environment where computers and users can communicate with each other. Therefore, in college teaching, we can apply multimedia teaching mode, rationally allocate teaching resources in different teaching links according to different teaching contents and teaching objects, fully and vividly simulate the teaching environment, and organize students to adopt various effective learning methods to achieve their learning goals in the most economical and direct way.

Second, the main problems in the application of multimedia teaching in ideological and political theory courses

Multimedia teaching has become an indispensable teaching aid for ideological and political theory courses in colleges and universities, and its application has unparalleled advantages in enriching and improving the effectiveness of ideological and political theory courses in some aspects. But in general, the specific use can not achieve the expected results. Through the analysis of lecture records and teaching effects, it is found that there are the following problems in multimedia teaching of ideological and political courses:

(A) courseware making emphasizes form over content.

The production of multimedia courseware is an important factor affecting the teaching effect of ideological and political theory courses. At present, the production of multimedia courseware for ideological and political theory courses emphasizes form over content. Some teachers lack organization and refinement when making courseware. Courseware is purely "textbook transfer" and "handout transfer", and there is no substantial change from traditional teaching. Computer is the memory of teaching materials. Some teachers blindly pursue novelty and movement in form, and use too many strong colors, rich pictures, changeable animations and strong music. Courseware is too flashy and thin, and as a result, it is easy to distract students from learning content and knowledge points and dilute the teaching theme. There are also some courseware with too much information and too short information retention time for students to fully digest and accept; Some young teachers mainly make courseware, ignoring the preparation of other teaching links, which affects the overall teaching effect.

(2) Teaching courseware is lighter than teachers and students.

Because multimedia has many advantages in ideological and political theory teaching, some teachers overemphasize the role of multimedia courseware and rely entirely on courseware teaching. Class is like showing a movie. The teacher keeps demonstrating the courseware, and the students keep their eyes on the screen. The computer and the screen become the protagonists in the class, and teachers and students revolve around it, which greatly weakens the leading role of teachers and the initiative role of students. Teachers and students are the main body of classroom teaching, and computers are only auxiliary teaching means. The purpose of using computers is to better mobilize the classroom atmosphere and stimulate students' enthusiasm to participate in learning, rather than replacing teachers' teaching. However, if we rely too much on courseware, the teaching content will not leave more time for students to think with the browsing of multimedia courseware, and it will be impossible to ask teachers some discussion questions related to the course, thus making the classroom teaching atmosphere dull and the interaction between teachers and students weakened.

(C) modern light traditional teaching methods

In traditional teaching, teachers can communicate with students through body language, and teachers' behavior plays a subtle role in students. After adopting multimedia teaching, some teachers overemphasize modernization and networking, while ignoring the use of traditional teaching methods, and blackboards and chalk become furnishings. In particular, some teachers dub the courseware, or speak in an announcer's tone from beginning to end, turning the teachers into "projectionists" and "broadcasters" and losing the due value of multimedia courseware. The application of modern educational technology is an inevitable requirement to improve the effectiveness of ideological and political teaching, but multimedia teaching does not exclude traditional teaching methods. Although the role of blackboard and chalk is weakening, the experience accumulated by teachers in traditional teaching, especially the improvement of teachers' professional quality and the accumulation of teaching art, still plays a decisive role in teaching effect.

Third, to promote the ideological and political theory of multimedia teaching countermeasures

There is no doubt about the superiority of multimedia teaching in ideological and political theory course, and the existing problems can be solved and improved in practice. In order to overcome the shortcomings of multimedia teaching in ideological and political theory courses, give full play to the role of multimedia teaching and improve the quality and effect of teaching, combined with the current status and development trend of multimedia teaching in ideological and political theory courses, we can make efforts from the following aspects:

(A) comprehensively improve the quality of courseware production

In the multimedia teaching system, multimedia courseware is the most basic and core element. Courseware content should not only be closely combined with teaching content, but also fully reflect students' independent inquiry, cooperative discussion, active innovation and acquisition of knowledge and skills. When making courseware of ideological and political course, we should be guided by educational theory, follow students' cognitive rules, take the teaching syllabus as the basis, aim at specific teaching tasks and teaching objectives, rationally select materials, highlight key points, emphasize difficulties, and flexibly use words, images, animation, music and other elements to suit teachers' teaching style. In addition, you can also make a large number of structural diagrams of knowledge points, and clearly express the contents that are difficult to understand through the structural diagrams, so that the knowledge points can be more closely linked and students can form structured and systematic thinking habits. At the same time, all courses should advocate the collective development of courseware to realize the enjoyment of resources, and the selection of courseware materials should also be strictly controlled. In particular, the selection and playback of audio-visual materials should establish a relatively uniform standard and be as detailed as possible, which not only meets the needs of courseware making but also takes up too many theoretical teaching hours.
