Methods of Collecting Data

26 descriptive qualitative study which focuses on the analysis of the discussion. It is in accordance with Sulistyo 2008:110 who stated that descriptive approach attempts to find an exact and appropriate description for activities, process, and human. The simplest way to define qualitative study is to say that it is a study that involves interpretational data which will be interpreted descriptively.

3.4 Methods of Collecting Data

3.4.1 Questionnaire

Questionnaire deals with a number of relevant questions that should be answered by the students. For the purpose of the research, questionnaires were to find out the internet use among students and their perception of EdukasiNet in supporting their English skill. The hypothesis about the internet use among students and their perception of EdukasiNet in supporting their English skill were: 1 The students used to browse internet in supporting their lesson. 2 EdukasiNet is useful to support students’ English learning. 3 Some of EdukasiNet features are helpful in supporting students’ English learning.

3.4.2 Focus Group Discussions

A few words about focus group methodology are in order. Focus group discussion refers to a nondirective technique that results in the controlled production of a discussion of a group of people Flores Alonso, 1995, p. 84; 27 a moderator typically facilitates the discussion. Participants in focus group discussion constitute a purposive sample of the target population Lederman, 1990, and the number of participants in a focus group can range from 6 to 12 people. Focus group research is considered qualitative research. Qualitative research sometimes sacrifices reliability for validity. This means that although focus group findings cannot be replicated statistically as can sample surveys high reliability, they provide researchers with the opportunity to uncover salient issues high validity. Prior to focus group discussions FGDs, I contacted the teacher to choose the participants. I had to gather the students in the laboratory to ensure they had browsed EdukasiNet before I held FGDs. Therefore, I also asked the teacher to schedule the laboratory meeting. Typically focus group participants are unfamiliar with one another. However, certain school and grade situations make this nearly impossible. I used two rounds of focus group discussions in the study. The first round included 9 students of grade ten whereas the second round included 7 students of grade eleven. These focus group discussions lasted from 20 to 60 minutes. I classified them based on their classes to avoid discouragement among students. In conducting FGDs, Firstly, I gathered the whole participants in the laboratory to browse EdukasiNet. The next meetings, I held a meeting with one group and the next two weeks I met the other group. Having prepared a shortlist 28 of questions concerning EdukasiNet, I asked the students. I also encouraged the participants to discuss anything they believed to be relevant.

3.4.3 Constructing the Instrument

Research instrument is a means which is used by the researcher to collect the data. It is to make the researcher’s work easier and get a better result which is more accurate, complete, and systematic Arikunto 2006:160. It depends on the instrument whether the collected data is good or not. A research instrument has to meet the terms namely validity and reliability. There are some steps in constructing an instrument as follow: 1 Preparation or constructing questionnaire: a. Determining the indicators b. Determining allocated time to work on questionnaire c. Determining the items d. Constructing a questionnaire score 2 Implementation. It is the step where the questionnaire is tested to sample participants. 3 Analysis of the Instrument. It is the step to analyze the result of the questionnaire to investigate the validity and the reliability of the instrument before it is given to the real participants. 29

3.4.4 Validity of the Instrument

When we measure something, it is a must to use an appropriate instrument. Likewise, the questionnaires which are used in this study have to measure what it should measure. It means that the questionnaires are appropriate to measure the extent of the research. Burhan 2005:97 said that instrument validity is the accuracy of instrument to what it measured although it is done for several times and places. Hammersly 1990 in Silverman 2000:175 said that validity is another world for truth. It is interpreted as the extent to which an account accurately represents the social phenomena to which it refers. There are some steps to test instrument validity: 1 Constructing the table to value instrument validity for students’ perception toward EdukasiNet. 2 Correlating score of each item and total score. 3 Consulting the result by using r table. In measuring the validity of questionnaires I used Pearsons’ Product-Moment Correlation The formula for Pearsons’ Product-Moment Correlation is: r xy = } { } { ∑ ∑ ∑ ∑ ∑ ∑ ∑ − − − 2 2 2 2 Y Y N X X N Y X XY N 30 Note : r xy = correlation coeficient N = total of participants X = total item score Y = total score The result of r xy is consulted with product moment critic r xy score which have real level 5 and confidence interval 95. If the score of r xy value is bigger than r table , the item is valid.

3.4.5 Reliability of the Instrument

Burhan 2005:96 said that instrument reliability is the degree of consistency between the instruments and what it is measured. Hammersly 1990 in Silverman 2000:175 said that reliability refers to the degree of consistency with which instances are assigned to the same category by different observers or by the same observers on different occasions. The result of reliability is consulted with r table significance average 5 . If r value is bigger than r table , the instrument is reliable. In testing the reliability of questionnaires I used Alpha: r ⎥ ⎥ ⎦ ⎤ ⎢ ⎢ ⎣ ⎡ − ⎥⎦ ⎤ ⎢⎣ ⎡ − = ∑ 2 2 11 1 1 t b k k σ σ Note: r11 = Instrument reliability 31 k = total item ∑ 2 b σ = total item varians 1 2 σ = total varians Arikunto 2006:196 If r 11 r tabel ,the instrument is reliable. But if r 11 r tabel the instrument is not reliable.
