b. Morphological Structure Awareness Test
The other kind of Morphological Awareness Test used in this research was Morphological Structure Awareness Test. It aimed
at measuring the students’ ability of morphological structure awareness. It required the students to make use
the linguistic knowledge to derive new meaning .
There were ten questions in the test of morphological structure awareness. Each question provided an example
sentence as the clue for the question. The students needed to relate the clue of the example sentence to be applied to the questions as the answer. It required the
students to produce words or phrases after examining the clue in the example sentence. One point was given for every correct answer. The total score was ten.
Correct spelling was important because misspelling might affect the meaning of the words. The questions varied from plural noun, S-V agreement, past verbs, and
compound words.
G. Validity and Reliability of the Instruments
All of the instruments used in this current study were instruments which widely used in the language research. Nation was well known for his instruments
which measure some aspects of vocabulary. One of the instruments was Vocabulary Size Test. The instrument was proven to be valid and reliable. This
current study adopted the instrument to be used to obtain the data of vocabulary size. A pilot project was conducted to get the picture of the data of the tests.
In addition, the current study adopted the instrument of morphological awareness test from the study done by Farsi 2008. Originally, the instrument
45
was adapted from the original version of Morphological Awareness Test by Chang, C. M., Wagner, R. K., Muse, A. Chow, H. S 2005. There were two
kinds of test i.e. Morpheme Identification Awareness Test and Morphological Structure Awareness Test.
H. Data Analysis
The data obtained was analyzed by SPSS program. The statistical technique used to analysis the data was Correlation of Pearson Product Moment
. The first
step the data analysis was about the normality and linearity of the data distribution .
It was used to fulfill the requirement for further analysis. Correlation of Pearson Product Moment was used to measure the correlation of the variables. The
coefficient correlation was used to find p-value for each analysis. The p-value was used to reject or not to reject the null hypotheses. Null hypothesis was rejected if
p-value 0.05, while null hypothesis was not rejected if p-value
0.05. The first data analysis was about the correlation between vocabulary size
and morpheme identification awareness. The null hypothesis “ There is no
correlation between vocabulary size and morpheme identification” was rejected if p-value
0.05. In other word, there was a correlation between vocabulary size and morpheme identification awareness. The second analysis was the correlation
between vocabulary size and morphological structure awareness. The null hypothesis “ There is no correlation between vocabulary size and morphological
structure awareness” was rejected if p-value 0.05. It meant that there was a
correlation between vocabulary size and morphological structure awareness. The
