24 actively. He mostly used
Bahasa Indonesia
when talking to Rose at the beginning, but then he tried to use English. Unfortunately, he often created mixed utterances
when he spoke to Rose. Mr. and Mrs. X themselves used both
Bahasa Indonesia
and sometimes Javanese when talking to each other, although Rose was also there. However, they did not address Rose in Javanese.
They were chosen as the supporting participants of the study because they had the most frequent interaction with Rose. Thus, they played a big role in giving
authentic information to support this study. The information was given based on the guidelines from the writer, such as information about the set
ting of Rose’s daily environment, interlocutors, code-mixing emergence, and many more
supporting information see Appendix 1.
D. Research Instruments
There were two kinds of instruments used to collect data for this study, namely, observation sheets and an interview sheet. The following parts provide
more explanation about them.
1. Observation Sheets
This study was provided with some observation sheets as the guideline used to record data. There were two kinds of observation sheet, namely,
observation sheet for Roses parents and observation sheet for the writer. The observation sheet for Roses parents was used by the parents to note any of Roses
mixed utterances when the writer was not observing, whereas the observation sheet for the writer was used when the writer observed Rose directly. All the
25 observation sheets were intended to discover detailed information about
Rose’s code-
mixing production. They covered notes about Rose’s code-mixing production and the date of the occurring products. The example of the observation
sheets can be seen in table 3.1 and table 3.2. Table 3.1 shows the observations sheet used by Roses parents, whereas table 3.2 was the observation sheet used by
the writer.

2. Interview Sheet
In order to support the data collected from the observations, the writer conducted a focused
interview with Rose’s parents. A focused interview is an interview which is done in a short period of time Yin, 2009, p. 107. It allows the
interviewer to follow a certain set of questions Yin, 2009. Thus, it can be said that a focused interview only requires a short period of time because it allows the
26 interviewer to refer to a set of questions prepared previously. The list of questions
used in this study can be seen in Appendix 1. The interview was conducted in Semarang on April 26, 2013 and was recorded in form of notes. It attempted to
note the setting of Roses environment and any kind of informat ion about Rose’s
code-mixing.
