explanations” p. 35. In doing the interview, the researcher conducted a structured interview. As supported by Mackay Mountford 1978, “one
advantage of a structured interview is that none of them will be left answered and clarify
the misunderstanding that may happen” p. 22. For the procedure of the interview, the researcher first contacted the
related stakeholders and respondents to make appointments of where and when the interview would be conducted. On the defined time and place, the researcher
interviewed the stakeholders and respondents. The interview was recorded. The recorded interview was then transcribed and analyzed. Whereas, in conducting
interview with the selected wedding organizer in which the materials are implemented, the interview was also done in planning and main field testing. The
practicality of the interview is that the research asked the members and the members answered the questions one by one. This kind of interview is well-
known as focus group interview. According to Gall et al. 2007, “a group
interview involves addressing questions to a group of individuals who have been assembled for specific purpose” p. 244. Additionally, the answer delivered by
one member might support oth er members’ answers. Therefore, the interview is
addressed to the group of the members, not individually.
c. Observation
Observation is done in both preliminary field testing and main field testing. Gall et al. 2007 state that observation is an activity to observe the
behavior and the social physical environment of the individuals being studied p. 263. However, the observation conducted in the research is not as deep as what
70
other observers do in other fields. It means that, the observation results support and complement the results of other data gathering technique in this research.
In the research, the observation was done by both the evaluators of the materials and the researcher as the practitioner of the materials in the
implementation. The evaluators will given enough time to observe the materials, so that they can give developing comments and suggestions for the better version
of the materials. Meanwhile, in the materials implementation, the researcher observe students’ behavior and also difficulties toward the using of materials in
the classroom.
d. Test
Implementing test in the research has two purposes. The first one was to obtain the learners’ English proficiency and the second one was to validate
whether the learners can successfully achieve the objectives of the materials or not.
According to Brown 2004, “a test is a method of measuring a person’s abi
lity, knowledge, or performance in a given domain” p. 3. Test, in the research, was conducted through pre-test and post-test. It would be used to
measure students’ ability before and after joining the English course. Moreover, Gall et. al. 2007 state that:
A test is any structured performance situation that can be analyzed to yield numerical scores, form which inferences can be made about
how individuals differ in the performance construct measured by test p. 193.
The results of the tests in determining the success of the learning
objectives would be used as the guideline for the researcher to revise the materials as well as become reflection after the materials were being implemented. The
