what it is supposed to measure, and should be practical to use. This claim means that the test is said reliable if it is consistent and dependable. Therefore, in the
questionnaire, the researcher included four statements which were wished to raise the students’ perceptions about the reliability of the tests. From the interview
conducted, the researcher attempted to verify the answers acquired from the questionnaire.
It had been shown that there were only 56 students who admitted that the tests were well designed and carefully written. The results of the interview
also demonstrated there were only three out of six interviewees admitting the tests were well designed and carefully written. Moreover, all interviewees suggested
the use of computer to replace the typewriter. They perceived that computer would make the design of the test better. The use of computer had been familiar in
recent days. Hence, it would be better to use the computer to construct the tests rather than the typewriter.
In addition, 92 students confirmed that the tests were really related to the material they had learned. The researcher also found out that the majority of
students felt stressed with the number of test items. As stated, there were 65 students confessing that they felt stressed about the number of the test items.
Furthermore, in correlation to the fourth statement, namely the coverage of the test, 90 students admitted that the tests covered all materials they had learned.
The data gathered from the interview conducted also verified that finding. All interviewees declared that the tests really covered all materials they had learned.
Accordingly, it could be concluded that the weekly tests actually had covered PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI

reliability. However, the use of computer was truly recommended in order to make the tests neat and carefully written.
4. The Students’ Perceptions on the Implication of the Test
The researcher had discussed the students’ perceptions on the process of vocabulary teaching and learning, the validity and reliability of the tests.
Subsequently, the researcher noticed what implications would emerge after the students worked on the weekly tests.
a. Perceptions on the Implication of the Test Based on the Questionnaire
Based on the results of the questionnaire as presented in Appendix 7, it was clear that the students in general had positive perception on the
implementation of the weekly tests. To be detailed, 87 students perceived that the weekly tests were important to enhance their vocabulary mastery. It meant that
actually to have vocabulary test every week was able to improve their capability of mastering vocabulary. There were 53 students who admitted this statement.
Another finding was there were 82 students who felt that the implementation of weekly tests was challenging. They were challenged since they must accomplish a
hundred items in 45 minutes in each test. In addition, weekly tests made 83 students become more diligent learners. Having test every week led them to have
study habit. They were supposed to repeat again and again so that they really mastered the vocabulary items planned to test. Besides, dealing with the
continuation of weekly tests, there were 48 students who remarked that weekly tests should be applied in Vocabulary I class. There were 78 students

considering that having weekly tests in Vocabulary I class had a lot of benefits, especially in enhancing their capability of mastering vocabulary.
From the open-ended questionnaire, 43 students confirmed the importance of maintaining this kind of test. Some students agreed with everything in this test,
but the other students suggested various improvements, such as to add the time allocation, to provide sentences to apply the words, to reduce the number of items
and to make use of computer rather than typewriter to construct the test. Nonetheless, there were 15 students who suggested replacing weekly tests with
two week tests In addition, there were three students suggesting not to implement weekly test anymore.
b. Perceptions on the Implication of the Test Based on the Interview
From the interview, it was found that student A, student B, student C, student D and student F admitted the weekly tests were important to enhance their
vocabulary mastery. In the interview, they affirmed that weekly tests not only enriched their vocabulary mastery, but also led them to memorize every single
word and its meaning time by time. Thus, they would not easily forget the words they mastered. Having a lot of words in mind really supported them in other
English skills as well, such as reading, writing and speaking. Nevertheless, student E had an opinion against the other interviewees. He
argued that the implementation of weekly tests was not important. The more effective way was to make a vocabulary test which provided sentences as context
to apply the words. Then, the implementation of vocabulary test should be once PLAGIAT MERUPAKAN TINDAKAN TIDAK TERPUJI
