B. Respondents
As mentioned earlier in chapter one that the study conducted at Faculty of Engineering, Yogyakarta State University. This faculty is located in
Karangmalang, in the Sleman District of Special Region of Yogyakarta. As stated by Dornyei 2010, the sample size for research participant
should be large enough to reach statistical significance, and certain statistical procedures may require a certain number of participants. The sample was taken
referring to Issac and Michael with the degree of significance of 1, 5 and 10 presented on the table. According to Isaac and Michael, with margin of error of
5, the population of 1000 participants need, at least 258 for the sample size Mulyatiningsih, 2012:18.

the frequencies and percentages for gender as well as academic majors. As for gender, about 67.8 of the respondents were male, and about 32.2 were female.
In terms of academic major, 18.2 of the participants majored in Civil Engineering Education and Planning, 7.8 majored in Fashion Design, 7 major
in Culinary, 6 major in Informatics Engineering Education, 7.8 majored in Electronic Engineering Education, 7.4 majored in Mechatronic Engineering
Education, 7.8 majored in Electronic Engineering Education, 7.4 majored in Electrical Engineering Education, 10.9 majored in Automotive Engineering

C. Instrument
The main instrument of this reserach is questionnaire. As defined by Brown 2001, “questionnaires are any written instruments that present
respondents with a series of questions or statements to which they are to react

either by writing out their answe rs or selecting from among existing answers” p.
6. Also, Mackey and Gass 2005 suggest that the questionnaire is one of the most common measures of collecting data on opinions from a large number of
participants in second language research. As pointed out by Dornyei 2010, the main advantage of questionnaires is their efficiency in terms of research time,
research effort, and financial resources. This study used a new design instrument of linkert-scale questionnaire as
the main instrument. The questionnaire contained 30 statements followed by column showing the range of responses from extremely agree, agree, disagree,
and extremely disagree. The respond item of “doubt” was deleted in order to
avoid the bias interpretation. The statements in the questionnaire were written in Indonesian to make sure the respondents understand the meaning of the
statements. This questionnaire was designed to
investigate students’ beliefs of language learning, which was devided based on the literature in 1 theory of
language, 2 language skills, 3 language learning, 4 self-esteem, 5 learning sources, 6 being English learner. Each theme refers to the following components
to address as presented below in Table 3.4. Table 3.4. the questionnaire blueprint
