4. Catalytic Validity
A research is valid if all participants are able to deepen their understanding of the social realities of the context and how they can make change within it. The
students’ perceptions related to the problems in this research were monitored and they were assisted in the implementation of the actions in order to allow them to
deepen their understanding and they can make change within it. 5.
Dialogic Validity Dialogic Validity is a process of peer review that is commonly used in
academic research. In this research, there were interviews with the English teacher and students to settle on the next actions. The interviews were related to the
implementation of the use of videos in the teaching learning process including the strengths and weaknesses to be improved in the next cycle.
To fulfill the reliability or trustworthiness of the data, the researcher used time and investigator triangulation proposed by Burns 1999: 164. In this
research, time triangulation was employed since the data were collected over a period of time to identify the factors entailed in the process. This research was
conducted from 1
st
April 2015 to 29
th
April 2015. Then, the researcher used investigator triangulation in which there was another observer who was the
English teacher as the collaborator in the same research setting to avoid observer bias and provide checks on the reliability of the observations. The researcher and
the collaborator observed the teaching and learning process and collected the data from the teaching learning process conducted by the researcher.
