The traditional network interactive teaching system does not consider the real-time interaction of teaching information resources, and there is a problem that students' teaching feedback is not in place. To this end, an interactive teaching system based on MOOC is proposed. The teaching system adopts the B/S mode, and divides the system into a presentation layer, a business layer and a data layer to improve the processing speed. And an interactive communication module is designed, which realises the real-time interaction of the video classroom in the network era, and achieves the purpose of cultivating students' independent learning ability. The experimental results show that the system improves the cognitive ability of students by about 20%, and improves the ability of students to develop learning plans, indicating that the system has a significant impact on the cultivation of students' self-learning ability.

Comprehensively improving the level of vocational education and teaching quality has become an important initiative to meet the new round of technological revolution and industrial change. The traditional teaching mode can no longer meet the needs of industries and enterprises for job competences, and all higher education institutions are actively thinking about how to carry out teaching reform. Virtual reality (VR) can effectively solve the above‐mentioned drawbacks, but the hardware facilities of the existing VR systems are extremely expensive, making it impossible to popularize it in teaching. In this context, this paper is based on VR for the design of an interactive teaching platform. This paper discusses the key technologies of virtual reality, introduces the relevant theoretical foundation, and describes the current virtual reality devices with high popularity and their advantages and disadvantages for systematic analysis. From the perspective of teaching design, the design of human‐computer interaction teaching process using VR technology to develop learning scenes is studied, introducing 3D modeling techniques, model construction, the production of picture and text panels, the production of video materials, and the establishment of virtual tour guide 3D scenes. The principle of this paper is to build a 3D vision for building 3D views of educational needs to design high quality images and video animation using 3DMAX and unity 3D engines. Then, we introduce the use of VR glasses (entry‐level), smart phones (android/ios), and Bluetooth wireless handle to build a simple interactive teaching platform; the platform is of low cost of construction and student coverage, to solve the teaching resources shortage, equipment conditions lagging behind, the curriculum content aging, teachers and students who cannot interact in real time, and a series of problems.

Ever since the new curriculum was implemented, Sichuan Agricultural University that is characterized by agricultural science has conducted ideological and political teaching reform, explored a basic route to integrate scientific outlook on development into theoretical teaching and initially formed a human-oriented interactive three-dimensional teaching system. In the practice of teaching reform, this university has insisted on healthy growth orientation of students and the basic principle of respecting students’ subjective status, stuck to the basic principle of the guiding position of Marxism and the leading position of students, set up the board of studies mechanism to direct students to take an initiative in participating in reform on theoretical teaching, constructed the self-education module of interaction of “explaining the theory” by students, set up the subjective teaching module of teaching leading and interaction between teachers and students and gradually formed the “quaternity” interactive teaching mode in which the four aspects of teachers and students, students and students, intracurricular and extracurricular resources and practice of students inside and outside the school interact with each other in an organic way. The result of the teaching reform practice is of demonstrative significance and promotion value.

At present, informationization education, as an important trend of modern education development, is gradually changing the traditional education system and teaching mode. However, there are many problems in the current ideological and political education model in colleges and universities, such as rigid teaching content, lack of teaching resources and single teaching methods, which seriously restrict the teaching effect of ideological and political courses and affect students' interest and participation in learning. In this regard, based on the actual needs of colleges and universities, this paper will deeply explore the feasibility of the application of interactive teaching mode in the field of ideological and political education, and put forward a set of brand-new interactive teaching solutions for ideological and political education in colleges and universities, aiming at breaking through many bottlenecks in the current ideological and political teaching practice and improving the teaching quality and effect. Practice has proved that the scheme realizes real-time communication and discussion between teachers and students by constructing an interactive ideological and political teaching platform based on WebRTC technology, thus enhancing the activity of the teaching process and stimulating students' interest in learning. At the same time, multimedia teaching resources will be integrated to provide students with richer and more intuitive learning materials and support personalized teaching to meet the learning needs of different students.

The generation and development of virtual reality technology provides new and powerful tools for the management of ideological education in colleges and universities. This paper focuses on exploring the utility of using virtual reality technology in college civic education. By selecting and deploying appropriate virtual reality display devices and development environments, we provide sufficient hardware and software support for the application of virtual reality technology to the ideology and politics classroom in colleges and universities. The browser/server 3-tier architecture model is introduced to develop this paper’s interactive teaching system based on virtual reality technology and integrate it with Civics classroom teaching. Students in the Civics classroom of University A are selected as the research subjects, and the eye movement index experiment is designed, which shows that the subjects’ attention time ratio and first-time attention time when using VR panorama learning are significantly improved compared with that of using static picture learning. The Civics classroom can easily accept this paper’s VR interactive teaching system, as demonstrated by the questionnaire results of the experimental group in two courses in teaching practice. At the same time, the mean values of the experimental group’s mind-flow experience and quiz scores using this paper’s system were 19.76% and 16.30% higher than those of the control group, and the degree of learning engagement was improved by as much as 78.556%, which effectively demonstrates the value and role of this paper’s VR interactive teaching system applied in the Civics classroom.

Modern distance teaching activities have occupied an important position in current education and teaching activities. This research mainly discusses the application of digital image processing technology in remote interactive art teaching systems. In order to avoid complicated calculation and a huge amount of calculation, reduce the difficulty of calculation, and improve the correction speed of distorted image and for qualitative recognition and correction of a large background and small target (or medium and small target) digital images (video is regarded as a special form of continuous image, method-like) that appear in a large number of remote teaching activities, this paper proposes a direct look-up method based on coordinate interpolation, that is, to establish the approximate correspondence between the image coordinate positions before and after the distortion and build a reference model for comparing the two image coordinates through experimental data. The system design includes overall design, functional module design, and database design. To realize the function of distance education, it must have characteristics different from ordinary networks and the most important thing is that its transmission bandwidth should be large. Because the distance education platform needs to be able to transmit the teaching text, hear the teacher’s voice, see the teacher’s teaching image content, and even see the carefully designed animation, the distance education system must have a very wide bandwidth. The database tables are designed using entity attribute diagrams and E-R diagrams. E-R diagram is also called entity-connection diagram, which provides a way to express entity types, attributes, and connections. It is used to describe the conceptual model of the real world. Remote online test management includes test content perform operations such as addition. The art teaching management system designed in the article will make teachers and students no longer be restricted by time and place and can inquire about students’ information, choose courses freely, inquire about grades, and understand the teaching plan anytime and anywhere. This research helps to promote the development of remote interactive technology.
