The paper will discuss the process of code-switching and its cognitive pragmatic motivation from the point of relevance.And code-switching is also regarded as a kind of communicative strategy.The process of the production of code-switching is also the cooperation and mutual constrain of communicator’s cognitive environment and ability.Cognitive effect can be obtained through communicator’s processing cognitive environment with their cognitive ability.In this process,the cooperation of cognitive ability and cognitive environment gives a guarantee to successful communication with code-switching. 展开更多

The idea of codeswitching was proposed since the 1970 s and has been heatedly discussed. This study will particularly focus on the motivations for code-switching on campus, especially for the reason of college students and teachers as frequent users. The study aims to find out if there is any relevance between one's English proficiency and motivation for code-switching. 展开更多

Code-switching between English and Chinese usually occurs in students' talk when they are involved in taking communicative language activities in college English class. This paper studies the situations in which students are likely to use codeswitching and analyzes it from the perspective of the mental world in Verscheren's Adaptation Theory. It shows that inadequate mastery of English language, cultural differences and the improper adjustment to context may lead to students' using of codeswitching. It also shows that the use of code-switching in students' talk adapts to students' cognitive elements and emotive elements as well. 展开更多

In the past 30 years, code-switching has been a focus in the field of linguistics in western countries. Researchers stud?ied it from different angles and have made a lot of findings.However, the researchers in China begin their studies on this issue un?til the last decade. Thus,the relevent empirical studies were less and most of them only use students from the classrooms in the sec?ondary schools or the undergraduates in the universities as the subjects.They paid little attention to the EFL classrooms in the vo?cational colleges. Vocational college students are poor in English foundation. English teachers can not finish their teaching mission in English classroom, so the use of code-switching becomes a very common phenomenon in EFL class of vocational college. In order to make teaching and learning promote and enhance each other, according to previous research findings, this paper do a fur?ther study about the teachers' use of code switching in the vocational college English intensive reading classes in China. 展开更多

This study investigates students’attitudes towards classroom code-switching(CS)between Chinese and English,and how such attitudes are influenced by learning motivation and language anxiety,the two focal variables of the present study.A total of 550 students from a university in northwest China took part in an online survey.The results of quantitative analyses suggest a division of attitudes towards CS,acknowledging its usefulness but dismissing its symbolic value.Such attitudes can be predicted based on the focal learner characteristics.The implications of the findings are discussed vis-à-vis the social psychology of CS and an optimal use of CS to assist language learning and teaching. 展开更多

Quantitative and qualitative research methods are adopted in the study. The case study centers on showing the attitude of teachers and that of students towards the CS to L1. It indicated that both teachers and students had positive attitude toward CS to Chinese in EFL classroom. The results in the classroom recording showed that students’ English proficiency level influenced the frequency of teachers’ CS;teachers alternate to Chinese mainly to facilitate students’ understanding or to emphasize some key points. 展开更多
