ng countries. Then, because many of the Indonesian people nowadays are good at English, those famous expressions or sayings can be quoted intact in their original language.
3. Being emphatic about something
Usually, when someone who is talking using a language that is not his native tongue suddenly wants to be emphatic about something, he/she, either intentionally or unintentionally, will switch from his second language to his first language. Or, on the other hand, there are some cases where people feel more convenient to be emphatic in their second language rather than in their first language.
4. Interjection (Inserting sentence fillers or sentence connectors)
Language switching and language mixing among bilingual or multilingual people can sometimes mark an interjection or sentence connector. It may happen unintentionally or intentionally.
5. Repetition used for clarification
When a bilingual wants to clarify his/her speech so that it will be understood more by the listener, he/she can sometimes use both of the languages that he masters saying the same utterance (the utterance is said repeatedly).
6. Intention of clarifying the speech content for interlocutor
When bilingual talks to another bilingual, there will be lots of code switching and code mixing occur. It means to make the content of his/her speech runs smoothly and can be understood by the hearer.
7. Expressing group identity
Code switching and code mixing can also be used to express group identity. As it has been mentioned previously, the way of communication of academic people in their disciplinary groupings, are obviously different from other groups. In other words, the way of communication of one community is different from the people who are out of the community (Barnett, 1994: 7).
E. Procedure of Research
This part presents the method of research, respondents, data resources, technique of data, and technique of data analysis. Each of them will be briefly described as follow:
1. Method of Research
In conducting this qualitative research, the researcher will use descriptive method to describe the result of the research. The collected data in the form of member’s responses to questioners and also study of the books will be identified and classified into certain categories. And finally, the data will be presented based on the analysis related to the research questions. This is accordance with Lexy,
“Bahwa penelitian kualitatif adalah penelitian yang bermaksud untuk memahmi fenomena tentang apa yang dialami oleh subjek penelitian. Misalnya perilaku persepsi, motivasi, tindakan, dll. Secara holistic. Dan dengan cara deskripsi dalam bentuk kata-kata dan bahasa, pada suatu konteks khusus yag alamiah dan dengan memanfaatkan berbagai metode alamiah” (1989:31).
2. Data Resource
According to the Creswell (1994:148) qualitative data can be collected through document analysis or visual material. The main data for this research will be taken from Social Networking Facebook and Respondents.
2.1. The Social Networking Facebook
The main data will be collected from Social Networking Facebook. Almost all of English Department Students are having facebook. Most of them connected one to each other by using facebook. There is also a group on facebook which overshadowed all English Department Students and the officials who are exist on facebook, this group also has a function as a forum to share all about English Department. In this group, the big family is gathering together. It make me easier to find out the data.
Beside that, the data will be taken from taking a questioner with the respondents I choose. The respondent is the member of social networking facebook. They are about 20 English Department members who surely always exists on that social network and also know much about the language they used on their sentences. Those are in line with Patton’s argument (1990:70) that is cited by Maxwell “Purposeful sampling is strategy in which particular settings, persons, or events are selected deliberately in order to provide important information that can not be gotten as well fr
