CHAPTER IV RESEARCH FINDINGS AND DISCUSSIONS
This chapter consists of two main sections, the research findings, and discussion. Those sections aimed at answering the questions presented in chapter
one. The first section provides information about a developmental pattern of Indonesian EFL learners in grammatical aspects acquisitions as the result of the
statistical data analysis conducted in Chapter three. This information on the developmental pattern intended to answer the first research question about the
developmental pattern of the Indonesian EFL learners. In addition, the result statistical analysis also utilized to answer the second research question about the
difference in the development of the acquisition of grammatical aspects of the second semester, the fourth semester and the sixth semester students of English
Letters Department. Further, the statistical data analysis leads to the answer of third research questions about the problematic grammatical aspects encountered
by the Indonesian EFL learners. The second section on the discussion part, there are the elaborations on the research finding related to the theories presented on
theoretical review.
A. RESEARCH FINDINGS
This study requires the obtained data to be analyzed to obtain information to be interpreted to answer the research questions. The obtained data is analyzed
with statistical software named IBM SPSS STATISTICS. In order to be able to determine the most appropriate data analysis technique using the software, it is
54 necessary to conduct a test to check the data normality. Therefore, the test of
normality and homogeneity must be carried out for every obtained data set. When the data is tested and it turns out that the data is normally distributed then the data
will be analyzed with one-way ANNOVA. In contrast, if the test of normality of the data set reveals that the data does not follow the normal distribution, the
further data analysis would be using Kruskal-Wallis H test.
1. The Developmental Pattern of Grammatical Aspect Acquisition
The analyzed data were obtained from the written test given to three groups of students. The test consisted of 36 test items with two sub-points in each
item. Point ‘a’ is intended to measure the learners’ acquisition grammatical aspects usage in a sentence. This point requires the learners to provide the most
appropriate verb form to complete the sentence; the grammatical aspects presented in the sentences become the consideration for the learners in providing
the correct verb form. Point ‘b’ intended to measure the acquisition on grammatical aspects identification. In this point, learners have to understand the
grammatical aspects of the sentence in order to be able to select the correct grammatical aspects whether it is simple, perfect, progressive, or perfect-
progressive aspects. Those 36 test items were constructed from four groups of test items representing each aspect: simple, perfect, progressive, and perfect
progressive aspects. Each aspect was represented in nine test items. As mentioned before, according to the normality test conducted to the
data set of this study the data set does not follow a normal distribution, therefore the Kruskal-Wallis H test was carried out to do further analysis. The following
