The quality of online education is closely related to the realization and effect of modern distance education theory in teaching practice. The communication and interaction between teachers and students is the basic guarantee for the success of distance education; Distance education institutions and educators should give more continuous care to learners; Students' autonomous learning and communication between teachers and students should develop in a balanced way. Therefore, teacher-student interaction is the basis of online teaching, and the quality and effect of teacher-student interaction is directly related to the quality of online learners' autonomous learning. ?

First, the status quo of online autonomous learning?

Autonomous learning in online education refers to learners' active, positive and conscious learning activities with the help of online education support system under the guidance of teachers and the cooperation of peers. Online autonomous learning has the following characteristics:

First, initiative. Learners decide their own learning methods, learning time and place, learning activities are initiated by learners themselves, and the completion of learning tasks mainly depends on learners' own consciousness and initiative. Second, independence. In online learning, learners do not rely on teachers or others to carry out learning activities alone, but mainly rely on learners' self-learning ability and self-control ability. Third, openness. The whole process of online learning is open, and learners can get other information related or unrelated to learning at will, even there is no fixed path for learning. Fourth, electronization. The medium of online learning is computer, and the learning resources it faces are the Wang Yang sea of Internet information. The presentation form of information is completely different from traditional classroom, showing the characteristics of electronic multimedia. ?

Network autonomous learning is mainly embodied in autonomous learning of network multimedia resources, which requires students to have different network learning ability, computer network operation ability, multimedia selection and use ability, hypertext reading ability, network interaction ability and so on. However, at present, the subjective and objective conditions of distance learners enrolled in online teaching institutions are diverse, and there are individual differences in age, learning experience, knowledge level, professional background, family life background, living environment, learning environment and learning motivation. Poor learning ability, many difficulties in learning, especially lack of confidence and motivation in learning, especially in economically underdeveloped or remote areas, there are few network computers, poor computer operation ability and poor network. ?

Second, efficient teacher-student interaction is the key to improve online teaching?

Generally speaking, students are not divorced from the guidance of teachers in the process of autonomous learning by using the network, but rely more on the guidance and help of teachers. Teachers publish teaching information through the network, assign teaching tasks, give appropriate guidance according to students' feedback information, and adjust teaching plans in time; Students accept the teaching information, explore and learn independently, ask the teacher about the doubts in learning, complete the learning task under the guidance of the teacher, submit the learning results to the teacher, and then know their own learning results according to the teacher's feedback information, so as to make necessary adjustments for the next step of learning. ?

Teacher-student interaction is the most important interaction in online teaching. Only when students interact with teachers and have individual guidance, guidance and help from teachers can learners' autonomous learning be lasting and effective. Let every learner feel the interest in learning and promote their interest in learning, so as to achieve the best teaching and achieve teaching goals. Therefore, only by making teachers and students interact happily can teachers and students gain something in teaching and students construct knowledge independently. ?

Under the network environment, because of the virtual teaching environment, teachers and students are in a state of quasi-separation, and the significance of teacher-student interaction is more significant, so it is very important to meet the needs of students' autonomous learning. The position, function and importance of teacher-student interaction in online autonomous learning are reflected in the following aspects: through interaction, teachers and students can inspire each other, promote each other and deepen their understanding, thus establishing a harmonious teacher-student relationship and creating a good online learning environment; Guiding students to carry out online autonomous learning is the most important position; It is an indispensable teaching link to ensure teaching quality and provide support services for students. It is an important means to turn the virtualization of network teaching into reality and create a better classroom atmosphere; It is a link to strengthen the contact between teachers and students and emotional communication. ?

Teacher-student interaction is very important for online autonomous learning for the following reasons:

(A) Teacher-student interaction is the basic point and starting point of online teaching?

The so-called interaction is communication, that is, communication between people. Interaction is an indispensable social activity for human beings. Through the interactive exchange of ideas and information, human beings turn one-way thinking into multi-way thinking, thus synthesizing new knowledge and promoting development. ?

In educational activities, interaction is the main way for teachers and students to exchange information. Teacher-student interaction runs through the whole teaching process, which is an indispensable and important means to cultivate students' learning interest, learning ability, develop students' intelligence and improve their learning level. It is also an effective way for teachers to understand students and adopt targeted teaching strategies. The success of education depends on the quality of teacher-student interaction. However, the characteristics of the network, that is, breaking through the limitations of time and space, provide very favorable conditions for the interaction between teachers and students, and can give full play to the advantages of network remote communication, so the interaction between teachers and students is the basis of network teaching. ?

(2) Is teacher-student interaction the need of students' dominant position in online education?

In the process of teacher-student interaction in network teaching, teachers should pay attention to student-centered, put students in the main position, always think of students and serve them everywhere. The interactivity of online teaching highlights the students' dominant position. To some extent, students are both recipients of knowledge and participants in education. Therefore, in network teaching, on the one hand, we should give full play to the leading role of teachers, and at the same time, we should stimulate students' subjective role and establish students' subjective consciousness. This determines that online education needs timely interaction between teachers and students and attaches importance to personalized learning guidance. In the process of interaction, teachers should pay attention to individual differences, teach students in accordance with their aptitude, meet students' requirements and adapt to the characteristics of autonomous learning. Fully stimulate students' enthusiasm for learning, give play to students' subjective initiative and creativity, and change passive online learning into active online learning; Decided that online education should focus on personalized autonomous learning, strengthen online autonomous learning guidance, and answer students' questions in time; It is decided that online education should interact with teachers and students through forums, answer students' difficult questions and make up for the shortage of teaching resources. It is decided that online education should strive to eliminate the sense of alienation and estrangement between teachers and students brought by the network environment, "all for students, all for students, all for students", impress students through their own words and deeds, gain their full trust, and establish a new relationship between teachers and students through timely interaction and communication. ?

Looking at the actual teaching situation of online education, the interaction between teachers and students is still not satisfactory. No matter between teachers and students, there is no really communicative interaction, and the quality and effect of interaction are still not high, which can not meet the learning needs of students and play a positive role in promoting students' autonomous learning. In order to solve the above problems, promote the sustained and healthy development of teacher-student interaction teaching activities and continuously improve the level of teacher-student interaction, effective measures and methods should be taken from teaching practice. ?

Specific to the current teaching practice of online education, "teaching interaction" is mainly reflected in a series of interactive activities between students and teachers in the learning process. There are many ways, such as students learning online courseware through online classroom, students communicating with online courseware and lecturers, and students interacting with teachers through bbs. It is also possible to provide a platform for students to communicate and understand through the construction of subject channels, where students can learn about the development of cutting-edge courses related to their majors and interested majors and other issues of concern. ?

In order to do a good job of teacher-student interaction and improve the quality of online autonomous learning and online education, we must treat online teaching with a brand-new concept, support online teaching with brand-new means, provide students with a good learning environment, and pay attention to enriching the content of online teaching so that students can always gain practical benefits. Therefore, as long as careful planning, careful design and full implementation, we can make a breakthrough. ?
