The arrival of the era of new media has greatly promoted the reform of ideological and political theory course (hereinafter referred to as ideological and political course) .Taking the exploration and practice of ideological and political teaching reform in Liaoning Agricultural Vocational and Technical College as an example, this paper analyzes the necessity of ideological and political teaching reform by using new media and new technology, and explores a teaching mode which closely combines theoretical teaching, network teaching and practical teaching, so that online and offline, theory and practice can support each other and jointly serve the growth and success of college students. Xi stressed at the National Conference on Ideological and Political Work that "Ideological and political theory courses should be strengthened in the process of improvement, new media technologies should be used to make work alive, and the affinity and relevance of ideological and political education, the sense of the times and attraction should be enhanced." The media is the medium of spreading information, the new media is the new medium of spreading information after the Internet and information technology appear, compared to the traditional media such as newspaper, magazine, broadcast, television, the new media such as WeChat, QQ, cloud class, various search engines, network television, have the characteristics such as instantaneity interaction and openness of information transmission, which have improved the efficiency of information dissemination greatly, and have expanded the scope of influence. New media, like an irresistible trend, has an unprecedented impact on ideological and political teaching. Ideological and political courses in colleges and universities, as the main position of establishing morality and cultivating people, must keep up with the pace of the times, focus on the ideological concerns and talent needs of college students, use advanced technical means and abundant teaching resources, constantly improve teaching methods and innovate teaching art, highlight the dominant position of students, stimulate students' interest in learning, improve students' ability to solve practical problems by using the theoretical knowledge they have learned, and constantly gather consensus and grow in an all-round way in self-study, theoretical discussion and practical training both inside and outside class, online and offline. 1 The Important Role of New Media in Mixed Teaching of Ideological and Political Courses in Colleges and Universities As a teacher of ideological and political courses in colleges and universities, we must study and learn new media, use its advanced technical means and abundant network resources to carry out teaching reform, in order to explore a mixed teaching mode that integrates classroom teaching, new media teaching and practical teaching, so as to integrate online self-study with offline learning, theoretical learning and practical training, so as to achieve the educational purpose of enhancing classroom charm, improving teaching effect and promoting students' all-round growth and success. 1.1 New media provides advanced teaching means for mixed teaching of Ideological and political courses Ideological and political courses in colleges and universities have certain ideological, theoretical Xi Jinping. Speech at the National Conference on Ideological and Political Work in Colleges and Universities. 2020 International Conference on Educational Science (ICES2020) DOI: 10.38007/Proceedings.0000339 ISBN: 978-1-80052-001-1 559 and political nature. It is difficult to stimulate students' interest in learning if teachers only rely on ideological and political courses to teach in the form of language. After the emergence of new media, teachers rely on computers, mobile terminals and Internet platforms to issue questionnaires, self-taught courseware, micro-lesson videos, discussion questions, homework and examination notifications through cloud classes, so that students' learning activities can be expanded from class to extracurricular, from passive acceptance to active inquiry. Through the analysis of the questionnaire data, the teacher grasps the students' ideological dynamics, and prepares and designs the teaching activities according to the problems reflected in the focus. In the course of the class, the main focus is on teaching difficult problems and answering questions. Students can preview what they have learned and master the basic theoretical knowledge well by watching micro-lessons and self-study courseware. Students take questions to listen to lessons and participate in discussions in and out of class, which helps students to form a correct understanding. Online testing enables students to consolidate their knowledge of residential science and reflects the learning effect. New media builds an interactive platform for ideological and political teaching activities, which integrates pre-class preparation, in-class learning and after-class practice, makes students become the main body of learning activities, greatly stimulates learning interest and improves teaching effect. 1.2 New media provides rich teaching resources for mixed teaching of ideological and political courses The so-called mixed teaching is to use new media technology and network platform, network resources to assist the teaching of ideological and political courses, so that advanced technical means and rich network resources can be applied to the teaching activities of ideological and political courses inside and outside the class, which not only plays the leading role of teachers in teaching activities, but also reflects the initiative, enthusiasm and creativity of students in learning activities to achieve the purpose of teacher-student interaction, teaching and learning, teaching and entertainment. With the rapid development of new media and new technology, Wechat, QQ, micro-class, MOOC and other network platforms and cloud class and other mobile phone APP are widely used in ideological and political teaching, injecting a fresh blood into teaching activities and providing rich teaching resources. First of all, the micro-class, MOOC provide a wealth of excellent materials for teachers. Teachers through the study of the national university micro-class teaching competition and other network platform of micro-class video and Tsinghua University MOOC video, can gather the advantages of others, draw on the teaching from famous teachers’ excellent teaching cases and advanced teaching methods in colleges and universities, to make full preparations for the development of teaching activities. Secondly, all kinds of cloud classes provide rich resources of self-study activities for students .Through mobile phone APP such as Blue Moyun Class, Erya Learning Tong and Intelligent Vocational Education Cloud Class, students can check the learning objectives, auxiliary courseware, teaching video, expand knowledge and other resources, and can study online anytime and anywhere after class so as to complete pre-class preparation and knowledge reserve. Finally, WeChat, QQ, Weibo and other network communication platforms become an important way to disseminate and obtain teaching information. Many people have the habit of leaving messages, forwarding articles and comments in WeChat circle of friends, QQ space, and Weibo. By browsing and paying attention to peer teachers, network commentators and others’ WeChat circle of friends, Weibo articles can obtain useful information, edited into vivid teaching cases, through the attention of students' WeChat circle of friends, QQ space can understand their thoughts, in view of their ideological dynamics can make targeted lesson preparation and answering questions and puzzles.
