C. Research Instruments
Instruments used in this study were questionnaires. Seligeer and Shohamy stated that a questionnaire is a printed form of data collection, which contains
questions or statements for subject to respond, often anonymously 1989. The advantage of a questionnaire is its ability to obtain data from a large number of
samples in a relatively quick and economical way. Ary, Jacobs and Razaveih 2002 said that there were two types of
questionnaire; structured and unstructured questionnaires. In structured questionnaires, both questions and answers are provided. Participants have to choose
the responses that best represent their own opinions, beliefs and suggestions using their own words. This model is easier to construct yet harder to analyze. In this study,
the writer distributed a questionnaire which combined those two types of questionnaires.
Instruments used in this study were needs analysis questionnaire, expert validation questionnaire and user validation questionnaire. The needs analysis
questionnaire was distributed during the research and information collecting step, while the expert validation questionnaire and the user validation questionnaire were
distributed during the preliminary field testing step. The needs analysis questionnaire aimed to collect information on learners’ characteristics, whose results would serve as
the basis for developing the materials. Therefore, needs analysis questionnaire covered areas such as the needs, capabilities, interests, academic factors, learning
styles and learning conditions of the learners. The needs analysis questionnaire was distributed to twenty staff of Bank Mandiri Yogyakarta.
Meanwhile, the expert validation questionnaire and the user validation questionnaire served as the evaluation sheets for the participants to assess the
designed materials. Evaluation was done based on the criteria provided in the questionnaires. The questionnaire itself consisted of two parts. In the first part, the
participants stated their degree of agreement on the statements constructed to assess the essential aspects in the materials, such as the relevance of the contents with the
learners’ needs, the elaboration, the activities and the outlook of the designed materials. There were four degrees of agreement to choose: strongly agree, agree,
disagree, and strongly disagree. The more the respondents agree with the statements, it can be inferred that the better the materials were developed. In the second part,
there were essay questions enquiring the respondents to write their comments and suggestions to improve the designed materials. The results of both parts would be
used as the input to revise and improve the materials. The user validation questionnaire was given to two English instructors of English for Specific Purposes
from Global Lingua Yogyakarta. The expert validation questionnaire was distributed to two English lecturers of the English Language Education Study Program of Sanata
Dharma University. Based on the explanation of the research instruments above, the writer
presented the data collection in Table 3.1. 45
