57 5. Dialogic validity
It means that the stakeholders who are involved play active roles in the process of the research.
This research involved the English teacher as the collaborator who also observed during the research process. This validity was fulfilled by holding
discussions with the English teacher as the collaborator before, during and after the implementation of the actions.
E. Data Reliability
Trustworthiness is another important aspect that needs to be fulfilled besides the research validity. In this research, to enhance the trustworthiness
of the data and the subjectivity in analyzing them, the researcher used triangulation. Burns 2010: 97 proposes three forms of triangulation: time
triangulation, space triangulation, and investigator triangulation. 1. Time triangulation
The data were not only collected at one time but added and completed over a period of time during the research. Before the research was done, the
data were gained by the observation on the English teaching and learning process. To strengthen the observation result, the interviews were also
done with the English teacher and the students as well to gain deeper information. After that, the data were acquired during the implementation
of the research which were happened for four meetings. The data were
58 obtained through various methods such as observations, interviews and
writing tests. 2. Space triangulation
The data were collected through various processes involving the students with various background of knowledge and different levels of English
proficiency. Since then, the result of the studies conducted was based on different groups. Every student had different characteristics and language
level of proficiency. The classroom consisted of 32 students which provided the various background of knowledge and they could be grouped
based on the characteristics. Therefore, the results of the research were according to different groups on the class.
3. Investigator triangulation In this research, the researcher did not stand independently since the
English teacher was fully involved as the collaborator and observer. The collaborator was actively played the role of being observer and helped the
researcher conduct the research to be succesfully done. The analysis was developed from the English teacher and researcher‟s point of view based
on observations and reflections made during the process of the research. Therefore, vague observation results and perspectives could be avoided.
