3.4 Technique of Data Collection
3.4.1 Observation Method
Observation is a method of data collection in which the interesting situation, action, natural phenomena and the work process are recorded
as an object of research. Sutrisno Hadi 1980 said that the observation is a complex process, a process which is composed of a variety of
biological and psychological processes. Based on the implementation process of data collection, observation can be divided into: participant
observation and non-participant observation. In participant observation, the researcher is involved in the daily activities of the observed object.
In non-participant observation, the researcher is just as independent observers. In this study, the writer tends to choose observation of non-
participant in the process data collection. The writer just sits in the classroom and records all utterances of the teacher in order to know the

The step of observation method is an effort of researchers to give data that are directly related to the investigated problem. The steps of
observtion are: 1. Observing the
object. The writer makes observation to the teacher’s behavior in the classroom when the teacher teaches and interacts
with the student. 2. Recording all the speech and behavior of the teacher when teaching
in the classroom. 3. Formulating a temporary result.
4. Identifying and classifying the data based on various code switching and the theory.

least amount of respondents. Based on the nature question, there are two types of interview, namely structured interview and unstructured
interview. Structured interview is a technique of collecting data with questionnaires that have been arranged. Unstructured interview is an
interview that is a free interview. The researchers do not use systematic and complete an interview guide to collect the data. The guidelines of
