36 Both LPD 2008 and CEPD 2011 provided a great help in comparing the
recordings with the correct pronunciation. Then, the researcher laid out not only the correct and incorrect stress placements but also the phonetic errors found in each
word.
F. Research Procedure
The following was the procedure the researcher followed to conduct his research. Each step was an essential progress towards the success of this research.
1. Identifying the Research Problems
Since the researcher was interested in English pronunciation, stress placement became the major focus of the research. The researcher finally came up
with an idea and sought to investigate ELESP students’ mastery of English suffixed
words. The first research question addressed students’ belief about the English word stress and the English suffixed words while the second research question asked
about students’ pronunciation mastery of English suffixed words.
2. Designing the Research
The researcher assumed that a mixed method would be a better approach to answer both research questions. However, after reading four books on research
design and research method, the researcher began to understand the nature of qualitative and quantitative methods better so that the researcher fully utilized a
37 survey method to answer all the questions. In applying the survey, the researcher
used an oral test and a questionnaire as the instruments that he piloted first.
3. Gathering the Data
In order to gather the data, the researcher defined the population and the sampling. It was determined that 116 students were the samples and were the
appropriate representation of 165 students – the accessible population. A
questionnaire was used to gather students’ responses related to their belief about the research topic. In addition, an oral test was also administered to record students’
performance in pronouncing English suffixed words. All prospective participants were given an oral consent form prior to being given a questionnaire.
Having done that, the researcher managed to continue the research in September. At this point, an oral test was administered to answer the second
research question. The speeches of the participants were recorded using audio- recording application available in every computer at Multimedia Laboratory. The
recordings were then transferred into a laptop.
4. Analyzing the Data
