CHAPTER I INTRODUCTION
A. Background of Research
Communication is a process of delivering a message. The message should be delivered in understandable language. To be understood by the others, someone needs to know some ways in using the language. Language is a communication device for people to convey what they feel, think, and desire. Thoughts, feelings and desires will be tangible when expressed with language. Language is also used for interaction with the social environment. In the speech, utterances are often used to change opinions, ideas, feelings, desires with the help of symbols called words.Meanwhile, according to Kridalaksana as cited in (Aslinda and Leni Syafyahya, 2010) language is a system symbol of sound used by members of a community to work together, interact, and identify themselves.
Based on the above statement that bilingual society is people who master in two languages. In bilingual community, speaker tends to switch from one code to another so that it can be understood by the other speaker from the other community. The process of switching code is commonly called code switching. According to Clyne as cited in (Rosul and Simin, 2016 ), code switching is a change by a speaker of a language or language variety to another. Many linguists believe that code switching is not only taken in informal situation but also in formal one, including in the classroom. In an educational context, code switching is defined as the practice of switching between a primary and a secondary language.
The fact of the use of mother tongue or first language with foreign language in the teaching learning process which called code switching cannot be avoided. The teachers consider that the use of code switching tend to be able to ease the students in comprehending English material. The other hand, sometimes the teacher switches their talks from English into Indonesia language in order to make students understand toward teacher’s explanation.
education, English is taught from elementary school until senior high school and the government has provided the facilities for it. Then the teacher should give big contribution towards students’ language growth. More English language used by the teacher in English classroom is better than not at all or even change into English-Indonesia. Many English words heard by the students, it’s good for the students. They will accustom to study English independently.
One of the schools which use code switching in teaching learning process is SMP Negeri 3 Purwokerto. The fact was revealed when the writer was doing an assignment to observe SMP Negeri 3 Purwokerto to know the teaching and learning process of English subject. Inspired by those facts the writer wants to investigate the use of code switching in the teaching learning process in a research entitled “A Study on Code Switching of Teacher Talk in
English Classes”. The writer’s reasons in choosing English teachers because
in SMP Negeri 3 Purwokerto, when teaching learning process teacher talks used English is limited and sometimes the teacher switch their language from English to Indonesia language. Looking at those reasons, the writer assumed that there will be a lot of code switching.
B. Reason for Choosing the Topic
1. The topic is very interesting for the writer because the use of code switching is not only occurring in informal but also in formal situation (teaching and learning process).
2. Code switching in a part of language teaching. When a teacher talk in the classroom dialogue is consisted of all English, it will give big contribution towards students’ language growth. More English language used by the
teacher in English classroom is better than not at all or even change into English-Indonesia. Many English words heard by the students, it’s good for the students. They will accustom to study English independently.
C. Problems of the Research
Based on the background above, the problems are formulated as follows: 1. When does a teacher use code switching in her classes?
2. How long does a teacher use code switching in her classes?
D. Aim of the Research
The aims of the research are at:
1. Describing the situations a teacher uses code switching in her classes. 2. Knowing how long a teacher uses code switching in her classes.
E. Contribution of the Research
1. Theoretical Benefit
This research proves the theories of code switching. This research improves language science in field of sociolinguistic. In the interaction between teacher and students in English classes, code switching sometimes happens and the use of code switching has effects to the students’ ability to learn English independently.
2. Practiced Benefit a. For Teacher
To give contribution of information concerning knowledge and comprehension exactly about code switching. The point of this research can give a hand about sociolinguistic strategies. These strategies can be used by teacher in teaching learning process in order to their students easier to comprehend that teacher talk.
b. For Reader
F. Clarification of the Key Term 1. Code switching
Code switching is the case of switching between two languages during the course of the conversation.

Code switches also play the role of defining an addressee as the recipient of a message. Here, the speaker switches to a language the interlocutor knows for example, when conversation is ongoing in a bilingual situation, a switch is made to a particular language especially for someone not immediately involved in the conversation in order to invite that person to participate in the interaction.
2. Teacher talk in English classes
