B. Theoretical Framework

In order to conduct this research, the researcher presents a theory in which appropriately suits as a framework to excavate and analyze the data of the research. Moreover, theories used by the researcher will be a starting point to answer two problem formulations questioned by the researcher. The researcher employs a theory of types of code switching, which are tag-switching, intrasentential switch, and intersentential switch, from Stockwell 2002 in order to answer the first problem formulation. This theory will be a basis to reveal the first problem formulation which is used to analyze types of code switching occurs in Facebook, particularly those Facebook users whose pages contain the data that being targeted. This theory is selected because the researcher finds it easy to comprehend and it is sufficient enough as a tool to answer the first problem formulation. In the matter of revealing the reason for doing code switching within Facebook, the researcher combines theories from Crystal 1987 and Wardaugh 1992. The combination of those theories is employed because those theories have similar interpretation in revealing the reason for code switching. As a result, there are three possible reasons for doing the language phenomenon. The combination of possible reason for code switching will be constituted as follows. 1. The first theory of reason for code switching is taken from Wardaugh 1992. Code switching is employed because the speaker has linguistic deficiency in order to communicate in one language. Otherwise, the speaker is not able to communicate the expession in one language. 2. The second theory is taken from Crystal 1987. It happens when the speaker switches his or her codes to have distinguished social status social recognition and it is used due to the situation where the speaker is in. 3. The last theory of reason for code switching is taken from Wardaugh 1992. Code switching is employed because of the choice of topic. Since the topic under discussion has special term, then Facebook users switched their language. All the theories presented by the researcher above will be the framework to analyze the research and hopefully those theories will help to answer problem formulations formulated by the researcher. encompasse this kind of social phenomena that occurred within social networking website Facebook. It was also essential thing to reveal reasons of using code switching used by Facebook users in their pages since the phenomenon of code switching was considered as social phenomena that occurred in social community. Merriam 2002, p. 2-3 stated that the understanding of the nature of qualitative research could be situated with the idea that meaning was socially constructed by individuals in interaction with their world, in which there were some actions or process of flowing of multiple constructions and interpretations. On the other hand, the meanings and interpretations they made might be changed continuously. Merriam 2002, p. 5-6 stated several characteristics of qualitative research in his book All qualitative research is characterized by the search of meaning and understanding, the researcher as the primary instrument of data collection and analysis, an inductive investigative strategy, and a richly descriptive end product. Thus, using qualitative research was the most appropriate method to convey this research, since the understanding was the goal of this study, and the human instrument came across as a tool of collecting and analyzing data.
