Data analysis technique RESEARCH METHOD

Meanwhile, to assess the reliability of the data, the researcher involved more than one source in gathering the data. The researcher involved the English teacher, the observer, and the students of grade VIII G. Regarding to this validity, some modification were applied so that the implementation of DRTA could be followed by the participants. 4. Dialogic validity Dialogic validity was fulfilled by discussing the research process and finding with the collaborators. The collaborators are the researcher’s colleague in the university. They gave their opinions and criticism about the action every time the meeting was ended. The researcher also had dialogues with the English teacher to ask her opinions and suggestions for the next meeting improvement. Through the dialogic validity, suggestions and correction were proposed by the English teacher and the observers. They were highly useful to evaluate the actions so that modifications could be made to provide the more suitable actions. Meanwhile, the trustworthiness was obtained from the triangulation technique. According to Burns 1999:163 the aim of triangulation is to gather multiple perspectives on the situation being studied. In this research, the researcher employed two forms of triangulation which are described as follows:

a. Time triangulation

Time triangulation means that the data are collected over period of time. It was done to get a sense of what factors are involved in change processes. In this research, the researcher conducted the actions from March-May 2015.

b. Investigator triangulation

Investigator triangulation means that more than one observer were involved in the same research setting. To fulfill the investigator triangulation, the researcher involved at least two observers during the action implementation i.e. the researcher herself and a collaborator. It was done to avoid bias or subjective observations.
