A research should not only be valid but also reliable. Reliability is used to enhance the trustworthiness of the data and to avoid the subjectivity in analyzing
the data. Burns 2010:97 proposed four forms of triangulation. However, this research applied only two of the triangulations. They are:
1. Time triangulation
Time triangulation means that the data are collected at different points in time. In this study, the data were collected from the month of February until
April. During that period of time, the research was done in two cycles, in which each cycle consists of two meetings. In total, there were four meetings
needed to conduct this research.
2. Researcher triangulation
In this triangulation, the data were collected by more than one researcher. The researcher investigated the research not only by herself, but
also by the English teacher and the researcher’s colleague. This is done to avoid bias or subjectivity.
Sugiyono 2013: 173 stated that an instrument can be said as reliable if the instrument had the same data when it was used more than once to the same
subject. The realibility of this research is tested using the Cronbach Alpha test in the SPSS 16 computer program. The instrument can be said as reliable or not after
the r
cronbach
is compared with the r
standart
. If the r
cronbach
is less than 0,600, the instrument is less good but still acceptable. If it was more or the same as 0,700,
the instrument is good and acceptable. An instrument is good if the r
cronbach
is more or
the same as 0,800. After analyzing the data using SPSS 16, the set 1 instrument
’s r
cronbach
was 0,914. Compared with the r
standart
which is 0,600, it meant that the set 1 instrument used in this research could be said as good. The r
cronbach
of the second instrument was 0.868. It also meant that the set 2 instrument was good.
