From the table, there is p-value 0.03 0.05. That is H
is rejected and Ha is accepted. Thus the hypothesis “There is no significant relationship between
vocabulary size and morpheme identification” is rejected. By looking at the table r = 0.267 show us that the degree of the correlation is low. In addition, the
correlation of the variable is positive meaning that the increase of the vocabulary size is in line with the increase of the morpheme identification. To sum up, by
looking at the data interpretation, it can be concluded that there is a positive correlation between vocabulary size and morpheme identification. It confirms the
previous study by Tabatabei in 2011 which studied the vocabulary size and morphological awareness of Saudi Arabia students. The study showed that there
was a positive contribution of the vocabulary size to morphological awareness. In addition, it is in line with the study by Wang and Chen in 2006 which resulted that
Chinese learners got positive advantage by knowing the structure of the English words.
2. Correlation between Vocabulary Size and Morphological Structure Awareness
The next statistical analysis is about the correlation between vocabulary size and morphological structure awareness. The result of the statistical analysis
by using Correlation of Pearson Product Moment is as follows.

. Correlation is significant at the 0.01 level 2-tailed. The second result is to test the second hypothesis H
“ There is no correlation between vocabulary size and morphological structure “ and Ha “There
is significant relationship between vocabulary size and morphological structure”. From the table there is p-value 0.001
0.05. That is H is rejected and Ha is
accepted. Thus the hypothesis “There is no significant relationship between vocabulary size and morpheme identification” is rejected. By looking at the table
r = 0.404 show us that the degree of the correlation is moderate. In addition, the correlation of the variable is positive meaning that the increase of the vocabulary
size is in line with the increase of the morphological structure awareness. It is in line with the study by Tabatabei in 2011 showed that the students had better
morphological structure awareness if they had more vocabulary size. Another study conducted by Deacon and Kirby in 2004 found that morphological
awareness could help the learners to reach better reading comprehension. Since
54
the reading comprehension was greatly influenced by vocabulary coverage and learners
’ vocabulary size, it was believed that indirectly the study showed the contribution of the vocabulary size and the ability to construct new meaning of the
words. To sum up, by looking at the data interpretation, it can be concluded that there is a positive correlation between vocabulary size and morphological
structure.
3. Correlation between Morpheme Identification Awareness and Morphological Structure Awareness
The last statistical analysis is about the correlation between morpheme identification and morphological structure. The table below will show us the result
of the analysis.

The third result is to test the second hypothesis H “There is no correlation
between morpheme identification and morphological structure “ and Ha “There is
55
significant relationship between morpheme identification and morphological structure”. From the table there is p-value 0.023
0.05. That is H is
rejected and Ha is accepted. Thus the hypothesis “There is significant relationship between vocabulary size and morpheme identification” is rejected. By looking at
the table r = 0.279 show us that the degree of the correlation is low. In addition, the correlation of the variable is positive meaning that the increase of the
morpheme identification is in line with the increase of the morphological structure. A study by Tabatabei 2011 found that the ability to break down the
words structure influenced the ability to construct new words. The learners developed receptive and productive skill of words formation if they had complete
thought of the words formation. To sum up, by looking at the data interpretation, it can be concluded that there is a positive correlation between morpheme
identification and morphological structure. Feldman 1995 suggested that the learning of morpheme should be done in whole mode. The students should
develop the awareness to recognize the elements of the words and synthesize the words elements to ensure that they could use the words in macro skills.
B. Discussion
The questions addressed by this current study are whether correlations exist between vocabulary size and morpheme identification; vocabulary size and
morphological structure; and morpheme identification and morphological structure. It was expected that the number of vocabulary size will positively
correlate with morpheme identification and morphological structure. In addition, this current study also assumed that there is a positive correlation between
