Research and Practice of Ideological and Political Teaching in Networking Technology Course

: Based on the orientation of the school, and the needs of the training goals of applied talents in computer science and technology majors, the employment-oriented, ability and quality assessment, as the center of the examination concept is explored in the new stage of the development of computer technology and the new situation of constantly changing teaching methods. While exploring the new ideas and contents of "Networking Technology" course in teaching content and teaching methods, integrating ideological and political elements, improving learning interest, stimulating innovative thinking, enhancing enterprising spirit, and cultivating students' comprehensive ability and quality.


Introduction
The ultimate goal of higher education is to cultivate morality and cultivate people, cultivate socialist pioneers and inheritors with a sense of social responsibility, practical ability and innovation ability [1][2] [3] .Therefore, ideological and political education is not only the task of ideological and political theory courses teachers, as every teacher in colleges and universities, should establish the consciousness of ideological and political education, and effectively realize the ideological and political work of colleges and universities from ideological and political courses to the transformation of ideological and political courses.
"Networking technology" course is a professional course for computer majors which combines theory and practice, involves a wide range of knowledge, has a great influence, in the traditional teaching focuses on imparting knowledge and training skills, but ignores the educational function of the course.Nowadays, the vast majority of college students are born after the "00" in the Internet information age, so their thoughts are easily influenced by various values and lack the initiative of independent learning [4] [5] .Therefore, teachers should not only do a good job in guiding students to be positive, optimistic and upward, shaping students' correct values, but also stimulate students' interest in professional knowledge learning and improve students' enthusiasm for independent learning.Under the mode of ideological and political education, on the basis of student-oriented knowledge impartation, the ideological and political resources in the course of "Networking Technology" and the strategic thinking of network power are deeply excavated, and the ideological and political education and the network power thinking education run through the professional knowledge teaching of computer science and technology courses.Through the close integration of professional knowledge education, network power thinking and ideological and political education, the value shaping, knowledge impartation and ability training are integrated, which has important practical significance for three-dimensional education.

The overall objective of ideological and political education in curriculum
The teaching object of "Networking Technology" is the third year undergraduates of computer major, who have certain basic computer knowledge and theoretical accomplishment.Knowledge objectives: mainly cultivate students to master the basic knowledge of network technology, strengthen the learning of core knowledge and frontier theory, and expand students' horizons and broad interdisciplinary knowledge.Competency objectives: through the study of this course, students have the basic ability to configure switches and routers skillfully, and the basic ability to design and build LANs.They have the ability to deploy TCP/IP applications, the preliminary ability to analyze protocols, and the ability to track new network knowledge and new technologies.In particular, they pay attention to the cultivation of practical and innovative ability, in-depth and independent learning ability.Quality objectives: cultivate students with a pragmatic spirit, based on disciplines and industry fields, pursue excellence and hard work, and become applied talents with patriotic feelings, social responsibility, innovative spirit and practical ability [6] .Through the integration of professional knowledge education and ideological and political education, value shaping, knowledge impartation and ability training are integrated.It is mainly reflected in the following three aspects:

In terms of ideology
Through the guidance of values, students' sense of value is cohesive;

In terms of content
Combining professional characteristics and trainings, with the help of "school-enterprise cloud", "rain classroom" and other teaching platforms to carry out teaching contents, so as to effectively integrate ideologicals and political elements and professional skills;

In effect
Increase the students' recognition of the socialist core values, and establish a correct concept of network security.
The implementation of ideological and political education in curriculum.
In order to better integrate the education of network power into the course of networking technology, in the teaching practice, the use of "Rain Classroom", MOOC and other online and offline mixed teaching methods, so that the ideological and political teaching of the course throughout the whole process of teachings, improve the overall awareness of participation.In the classroom, the full use of project-driven method, case analysis method, analogy heuristic method, task-driven and other teaching methods, while increasing the interest of theoretical knowledge, effective ideological guidance.With the goal of cultivating applied talents, and in accordance with the development trend of computer technology, the emerging teaching reform measures in the field of computer education are explored from the aspects of teaching content, teaching form, teaching means and so on.Centering on MOOC, SPOC and other methods, new teaching methods and new contents suitable for computer education are discussed, and the teaching reform attempts to stimulate students' learning interest and conform to the direction of technological development are highlighted.Effectively integrate online and offline education and teaching, the MOOC/SPOC-based course construction is built, and the research and application practice of new teaching models such as flipped classroom and blended learning are studied.
"Networking Technology" course is a basic course of computer majors on the basic knowledge of network technology in colleges and universities.Therefore, according to the teaching objectives and teaching content of the course, the ideological and political teaching of the course is implemented in the course, so that students of multiple majors in the computer college of colleges and universities can benefit at the same time.

The main elements of ideological and political education in curriculum
