Table 4.4 shows that the result of students‟ score in pre-test 43.33 while students‟ vocabulary in post-test became 78,00. Therefore can be concluded that there is an improvement students‟ vocabulary in terms of noun from pre-test to the post-test, the improvement was 80.00%.
3. Hypothesis Testing
To know the level of significance of the pre-test and post test, the researcher used t-test analysis on the level of significance (p) = 0.05 with the degree of freedom (df) = N-1 (30-1= 29), where number of subject the value of table is 1.699. The t-test statistical, analysis for independent sample is applied.
The following table shows the result of t-test calculation:
Table 4.5.The t.test of students’ improvement
Components t-test value t-table value
Verb 20.7 1.699
Noun 18.9 1.699
The table 4.3 shows that t-test value in terms of verb were greater than t- table (20.7>1.699), it means that there is difference between the students‟
vocabulary in terms of verb before and after using extensive reading. The table also shows that t-test value in terms of noun was greater than t-table (18.9>1.699).
It means that there is significance difference between the students‟ vocabulary in terms of noun before and after using extensive reading. Therefore the null hypothesis (H0) is rejected and the alternative hypothesis (H1) is accepted. That is also can be said that extensive reading is effective to improving students‟
vocabulary mastery at XI MIA 4 of SMA Negeri 2 Takalar.
B. Discussion
In this section, the researcher presents the discussion of the findings about the students‟ vocabulary improvement in terms of noun and verb in teaching learning process by using extensive reading. It indicated by students‟ score in pre-test and post-test.
The implementation of extensive reading could improve the students‟
vocabulary in terms of verb. The researcher found that before implementing extensive reading majority of students in pre-test was poor classification, but after implementing extensive reading students‟ score in post-test went up categorized as fairly good .By using extensive reading approach students can fulfill what they need to memorize the vocabulary because by reading with a lot, students can met words and looked up the unfamiliar word in the reading material. That is supported by Donaghy (2016) said that by implementing extensive reading approach students will meet a new vocabulary, therefore they learn more
vocabulary and memorize them. Nuttall in Ayuningtyas (2012) also said that extensive reading effective way to improve students‟ vocabulary mastery.
Students will have many chances to see word repeatedly by varied of reading material and become familiar with them. Therefore, it can said that there were improvement in students‟ vocabulary after did treatments by using extensive reading approach.
In addition it was supported by the mean score in terms of verb was 42.67 and after students were given treatments become 74.67. It showed that students‟
vocabulary in terms of verb improved better after implementing extensive reading was 75.00%. It meant that the competence students‟ vocabulary in terms of verb more improve after used extensive reading.
Besides that, by implementation of extensive reading could improve the students‟ vocabulary in terms of noun. The researcher found that before implementing extensive reading approach majority of students in pre-test were categorized poor, while after students were given treatments, students score in post-test rose classified as fairly good. Therefore, it could be conclude that there were improvement in students‟ vocabulary in terms of noun after implementing extensive reading approach.
In addition, it was supported by the mean score in terms of noun was 43.33 and after post-test became 78.00. It showed that students‟ vocabulary in terms of noun improved better after implementation of extensive reading was 80.00 %. Therefore extensive reading could help students to improve their vocabulary. That is also supported by Day and Bamford (2004) the students who
read more will not only became better and more confident readers but also the students‟ vocabularies will get richer. Anderson also said by doing activity of extensive reading students‟ reading fluency will increase naturally along with increasing students‟ fluency it become students more easy to understand the material and. also can building students‟ vocabulary because students read as much as possible, so students will met with new words.
The other researchers supported such as Ayu (2018) after implementing extensive reading activities the students got a lot vocabulary and students became more active in learning process. Sudirman (2017) found that by extensive reading could help students to improve their vocabulary. The result before applying extensive reading students‟ mean score in pre-test still poor and after applying extensive reading students mean score improved. That make students more confidence. Ayuningtyas (2011) found that applied of the extensive reading activities successfully improved students‟ vocabulary mastery by using book flood activity and telling truth. The students can memorize the words easily so that their understanding can increase. In addition this activities not only make them enthusiastic but also improve their activeness in the teaching and learning process. Arafa (2018), found that the result of implemented extensive reading activity successfully improving students‟ vocabulary mastery. Not only that the activities make the students more active in learning process and also motivation of the students can increase. Similarly in this research, the researcher developed students‟ vocabulary in terms of noun and verb. After implementing extensive reading not just improved students‟ vocabulary but students also more confidence
and active in learning process because they have many words and looked up the unfamiliar word in the reading material. Therefore it could be conclude that extensive reading approach can help students to improve their vocabulary.
According to Laufer in Tintari (2016) stated that vocabulary learning is at the heart of language learning and language use. Vocabulary has become powerful to improve achievement and can help students to communicate and express their ideas.
