G. Research Procedure
Aiming to find the answers to both research questions, the researcher conducted research on interrogative word question constructions. The research
was conducted in 2012, particularly in the odd semester of 20132013 academic year. The samples of research were students of Mathematics Education Study
Program of Sanata Dharma University batch 2010. Specifically, when conducting the research, the researcher committed to do the steps of conducting survey
research as follows:
1. Preparation
In the first step, the researcher did some preparation. The preparation includes the permission and observation. Before the research was conducted, the
researcher asked for permission to the Vice Chairperson of Mathematics Education Study Program of Sanata Dharma University. After being permitted,
the researcher met the English trainers, who were responsible to the classes of English Course, to ask for permission as well. Then, the researcher made
appointments with the English trainers, whose classes would be used to conduct the research, about the time when the research would be conducted. Next, the
researcher went to do short observation by attending a day-teaching learning

process in the classes where the research would be conducted. The observation aimed to estimate the level of English proficiency of the samples. Besides, the
observation also aimed to see what kind of materials that were being used to taught the students of PMat 2010 to know more about what kind of English they
learnt. Furthermore, the observation was also useful for the researcher to ease the process of designing the test items used as the instrument of the research.
2. Conducting Survey Research
The researcher previously conducted a pilot test. The pilot test was given to the samples of research to measure whether or not the test items were valid and
reliable to answer both research questions. The result gained from the pilot test showed that test items were all valid and reliable. It literally means the test could
be used to answer both research questions. Thus, the researcher could use the whole result gained from the pilot test as the valid data for the survey research.
The researcher was not required to revise the test at all and was not required to distribute another test to the samples.
During the survey research, the test sheets were distributed to the samples of research, which were students of PMat 2010, in the classroom. Each of them
would receive test sheets consisting 3 pages and covering 50 test items. The samples of research were given 45 minutes to answer the whole test items.
Additionally, the samples were given 10 minutes more to recheck their answers. Afterwards, the researcher collected the test sheets to be evaluated.
