Performance Analysis of Learning Efficacy of Interactive Foreign Language Teaching under the Network Environment

With the rapid development of computer technology and network technology, the integration between information technology and teaching promotes the development of interactive teaching under the network environment, which has a great impact on teaching philosophy, teaching method, teaching mode, etc., as well as brings concerns on learning efficacy under network environment to foreign language teaching. Analyzing learning efficacy for interactive teaching under the network environment is of vital significance for implementing the network teaching. Through making the survey of a total of 153 valid undergraduates’ questionnaires, and analyzing 153 undergraduates’ performance under the interactive network teaching environment via SPSS 17.0, the research shows that cultivating strategies of promoting students’ learning efficacy under the network environment should consist of improving network handling capacity, reducing computer anxiety, enriching successful network experience, etc. For foreign language teachers, more attention on students’ psychological behavior phenomenon in networking learning will also effectively promote the implementation of interactive foreign language teaching under the network environment.


Introduction
Under the network environment, interaction is playing a vital part in teaching process, and interactive teaching is closely linked with learning process and learning outcome. As the unification between learning process and learning a better understanding of learning efficacy under the network environment and to effectively promote the implementation of interactive teaching under the network environment, especially the interactive foreign language teaching under the network environment, it is necessary to make a performance analysis of students' learning efficacy under the network environment.

Interactive Teaching Theory
Interaction is one of the most fundamental methods of teaching. Interactive teaching idea emerged when the ancient Greek philosopher Socrates and traditional Chinese thinker and educationist Confucius sermoned and educated their students through conversational mode. With the constant development of philosophy, pedagogy, psychology, scholars have obtained more profound understanding of interactive education. In the mid-20th century, American psychologist and educationist Bruner stated the learning method based on psychological theory. He held that the learning process of students is an active knowledge discovery process, and believed that only by participating in cultural interaction can human brain be fully developed. Brown applied the idea of interactive learning into language teaching, systematically expounding the methods of interactive foreign language teaching and proposing corresponding teaching principles. He stated that interactive learning is that "two or more people work together, exchanging ideas, feelings or thoughts, to influence each other." (Brown, 1994). In fact, he thought that "interaction is the core of communication and is the core of the whole communication." (Brown, 1994). The cycle of any teaching processes must deliver, receive and explain information, and complete the stated teaching task together by discussing and understanding the meaning of language information in a specific context, so as to achieve the teaching goal. However, no matter how complex these processes are, interaction is always a vitally important part in the teaching process.

Concept of Learning Efficacy
At present, there is no uniform standard of the definition of "learning". On the whole, learning is a process in which learners spontaneously build their own cognitive structure. In the aspect of psychology, learning is the continuous change of experience action and thinking. In terms of the definition of the "effectiveness of learning", scholars hold different views. In China, Xiong et al. (2009) define the learning efficiency as: the sum of all learning-related resources which influence learners' learning effect is the effectiveness of learning goal, and learning efficiency is the multifactorial multi-dimensional structure. Yu (2012) holds that learning efficiency refers to the ability of obtaining knowledge, im- states that learning efficiency is inversely proportional to the working hours and learning time of learners, which is reflected in the learning effect. Jia & Lu (2014) thinks that learning efficiency is the measure of learning outcome, and learning efficiency, learning effect and learning benefit are the basis of measuring the learning efficiency. In foreign countries, learning efficiency mainly includes learning effect and learning satisfaction, in which the learning effect mainly focuses on the outcome of learning or the obtainment of knowledge and thinking skills. For quite some time, our country keeps emphasizing the choice and selection towards student assessment, focusing obsessively on result, ignoring the process, and neglecting the development of acquiring knowledge, ability, emotion and value. Development evaluation is to promote students' personality and integrated development, stressing process evaluation, emphasizing the new evaluation methods of improving and reward functions, paying attention to students' needs and evaluating in the process, in addition, students lay emphasis on their subject role, fostering knowledge, technique, thinking ability, innovation awareness and emotion value, as well as their learning, including learning strategy, learning motivation, learning attitude and so on.
Based on learning theory and development evaluation of constructivism, learning efficiency is mainly interpreted from the perspective of learning process and learning outcome (Ardura & Galán, 2019). Based on the connotation of effectiveness, the learning efficiency is defined as learners' degree of educational objective by using the research on learning efficiency of domestic and foreign scholars. The learning efficiency is interpreted as the following points: learning efficiency is the unification between learning process and learning effect, both of which are the efficiency of learning, and conform to the educational objective and current national quality-oriented education philosophy. The learning efficiency stresses not only the importance of learning effect, but also the internal psychology and behavior of learners in learning process.

Linguistics and Interactive Foreign Language Teaching
The teaching methods of any foreign languages have a guiding effect with linguistic theory, the influence of foreign language teaching theory on foreign language teaching is also applied in the foreign language teaching, and linguistic theory forms a significant branch of applied linguistics. Hence, its key point is "the systematic language teaching and learning based on language acquisition". Interactive foreign language teaching also has a solid language foundation. 1) Dialectical relationship between language and speech and interactive foreign language teaching Since the publication of Saussure's Course in General Linguistics, the philosophical principle of form and content and universality and particularity have been widely applied in the field of linguistics. As the social and systematic part of language, speech has universal motion laws, and as the use of language by individuals, speech is also the shell and form of the language and is restricted by language rules. In the process of interactive foreign language teaching, language serves as the basis of interaction, and is the specific content of the interaction, without language, the whole teaching process will be meaningless; On the other hand, without words to say, there will be no content in the whole teaching activity. Therefore, language and speech are two dialectically dependent necessary factors in language teaching. "Managing the relationship between language and speech in a correct manner is the key of foreign language teaching," Wang (2009) said. Traditional foreign language teaching theory is to learn language based on acquiring the language system. Therefore, we have acquired the language system of one language, but we still cannot correctly use it, and our language competence is not good enough. The foreign language teaching theory of constructivism emphasizes the structure of language form, students are able to make sentences which conform to grammatical rules, but these sentences are hard to be applied in real-life foreign language, there is a lack of elasticity in the language which is impacted by the native language. The interactive teaching theory combines the development of language and speech, seemingly providing a perfect answer for the language and speech issue.
2) Linguistic theory of constructivism and interactive foreign language teaching In the process of interactive foreign language teaching, teachers play a leading role and students play a subject role. During foreign language learning, students construct discourse by their own language knowledge to express thoughts and have information communication with teachers, classmates, computers as well as other external factors. On the other hand, they also construct text for new language materials in environment (including teachers, students, textbooks, computers, etc., and can provide various factors of language information), and construct personal foreign language system to achieve the interactive cycle between language and speech, so as to realize the purpose of mastering a foreign language (Zhang & Qin, 2014).
3) Cognitive linguistic theory and interactive foreign language teaching Cognitive linguistics is not only the reflection of brain's outside world by language, but also the results of understanding the outside world. The learning of language knowledge is achieved by the interaction between subjective world and objective world. For example, the establishment of the concept of language category is based on experience and imagination, which is the interaction result between subject and object. The way of classification can be sensory, kinaesthetic, metaphorical or image schema thinking. We cannot obtain the meaning of category through abstract and meaningless symbol operation. The meaning of language is mainly derived from the interaction between human and objective world, from the viewpoint of users to the objective world, it is the result of con-Z. X. Wei Open Journal of Modern Linguistics ceptual process. As a result, language is not only a thing with form and a set of rules system, but the assistant instrument and means for the interaction between human as the subject and objective world as the object (Saussure, 2001). Language system is dynamic and comes from the language use. Language subsystem has the characteristics of interactivity, hierarchy and timeliness. Grammar changes gradiently, and learning is progressive, existing in specific environment and completed by a specific participant with a clear aim.

Experiment and Analysis
To get a better understanding of learning efficacy of interactive foreign language teaching under the network environment, a survey of undergraduates' learning efficacy under the network environment is made through the experiment, in which the questionnaire and data statistics methods are mainly adopted. During this experiment, it should be explored: Does the gender, the grade or the major category of undergraduates relate to network environment learning efficacy, if it does, how to affect network environment learning efficacy? Which feeling (ability) affects undergraduates' network learning activity and learning behavior and to which extent?

1) Analysis of the basic information of questionnaire
In this experiment, random sampling is undergraduates from freshman to se-  Table 1.
Overall, the structure of the samples surveyed is relatively balanced and is suitable for research. According to Table 2, the mean of gender is 1.5686, which is biased towards 2, indicating that the number of females is greater than that of males. The mean of grade is 2.4183, which is between 2-3, indicating that there is a relatively large number of sophomores and juniors. The mean of major category is 1.3922, which is biased towards 1, indicating that the major category of samples is scientific technology rather than literature and history. 3) Tabulating analysis is conducted combined with the difference of the feeling of competence between gender and major category.
According to Table 4, there is a significant difference in the network environment efficacy of undergraduates of different majors. The mean of the feeling of competence and hard work of male undergraduates in science and engineering is 17.92 and 16.95, respectively, and that of the male undergraduates in literature and history is 18.48 and 17.37, respectively, showing that the feelings of these male undergraduates are generally similar, but the male undergraduates have slightly Statistical drawing analysis is conducted for the difference between grades and dimensions stronger feelings. Observing the data in Table 4, we can see that the feelings of control and environment of male undergraduates in literature and history are generally similar to that of the male undergraduates in science and engineering, but the latter's feelings of control and environment are slightly stronger. According to Table 5

Summary of the Survey of Undergraduates' Network Environment Efficacy
The structure of constructing undergraduates' self-efficacy scale network environment includes four dimensions, network learners' self feeling of competence, self feeling of hard work, self feeling of environmental control and self control of own behaviors (Durak, 2018). Research shows that the personal basic condition of undergraduates has an influence on their self-efficacy in network environment, the network environment self-efficacy level of male undergraduates is higher than that of female undergraduates, the self-efficacy level of undergraduates in literature and history is higher than that of those in science and engineering, and there is a significant positive correlation of hard work between feeling and control level. The cultivating strategies of promoting undergraduates' network environment efficacy consist of improving undergraduates' network handling capacity, reducing computer anxiety, enriching successful network experience, etc, whose validity is verified through experiment.

Conclusion
With the deepening of research on psychological behavior phenomenon in using network, the research of network learning self-efficacy has drawn increasingly more attention, especially in interactive foreign language teaching under the network environment (Bajorek & Gawroński, 2018). As the above research shows, the gender, the grade and the major category of learners are related with network environment learning efficacy. Hence, to effectively improve learning efficacy of foreign language teaching, it is necessary to construct a personalized independent network-related learning environment, to create more learning activities that can enhance the information literacy of learners. Besides, the cultivating strategies to promote learners' network efficacy can be adopted, such as enriching successful network experience, strengthening learner's network handling competence and forming the male-together with-female learning community, which will be beneficial for learner's efficacy of interactive foreign language teaching under the network environment.
