Table2. The Collecting Data
Those techniques can be explained briefly by following means:
1. The Qualitative Data
1 Interview
According to Burns 1999: 117, interview and discussion is face to face personal interactions which generate data about the research issue and
allow specific to be discussed from other people’ perspectives. In this research, this technique is held in the beginning and ending of the research to know the
teacher’s view of the teaching learning process, students’ vocabulary mastery, students’ achievement in English and students’ motivation before and after the
action. 2
Observation Burns 1999: 80 says that observation is taking regular conscious
notice of classroom action and occurrences which are particularly relevant to the issues or topics being investigated. In this research, observation was done by
21
the teacher. Observations are ways of finding out more about the student’s responses. Students’ behavior and activities were observed during English class.
The observation was focused on the development of students’ vocabulary mastery by using visual aids. A way of reporting observation can be done by
keeping field notes. 3
Documents In this research, the researcher uses some documents, they are:
§ Photographs Photographs are record of activities happening in the class. It could give real
description about teaching learning process. § Students’ diaries
The students’ diaries are used to investigate the student’s undetected responses by both teacher and the observer. The activities refer to the
student’s responses to visual aids displayed in the classroom, whether they see the visual, read their word, touch the things, or not.
§ Students’ answer sheet There are two students’ answer sheets: pre test and post test answer sheets.
2. The Quantitative Data
Test The researcher gives tests to know how far the result of the
technique that is used to improve students’ vocabulary mastery is. There are pre-test and post-test which are used to collect the data of the improvement.
