48,33 Based on the table above, it can be concluded that there is improvement of
students’ score at pretest and posttests. It also can be seen that the students gained a good achievement at posttest 2.
2. Research Discussion
The last step of action research was discussing the research result. The objective of this research was to enrich students’ vocabulary mastery and improve
classroom situation. Based on the data obtained from research findings, it could be seen that the implementation of YouTube video gave its contribution toward the
attempts on enriching the students’ vocabulary mastery. Those findings are discussed as follows:
a. YouTube video can enrich students’ vocabulary
YouTube video that the writer implemented in teaching learning process during the research could improve the students’ vocabulary. This improvement
include: 1 students could recognize vocabularies related to the topic given; 2 students could mention vocabularies given before; 3 students could grasp the
meaning of words well; 4 students were able to pronounce words correctly; and 5 students could write words correctly. These findings are supported by the
research result stated in pretest and posttests that there is improvement of students’ score that higher than the passing grade, 70.
The finding of this research show that the students could recognize the words given easily since they learned by using YouTube video because it not only
shows the writing of words but also its pictures. It is supported by the article entitled “Learning Vocabulary through Authentic Video and Subtitles” no-name,
undated that the great value of video lies in its combination of sounds, images,

and sometimes text in the form of subtitles. Subtitles can be used together with authentic video to improve word recognition and vocabulary acquisition skills in
the EFL class. As stated by TE Editor 2003 young children love to hear stories again
and again and the same goes for video. By watching a video several times, children can learn by absorption and imitation. This statement supports the
research finding that students could mention words given before easily because they have memorized them in their mind. More often the students watch
vocabularies shown on the video, it will be much easier for them to memorize it. In this study, the findings also show that the students can be easier in
grasping the meaning of words. Wade 2010 states that visual images of video help to convey meaning. Similarly, Wilson 2000 who suggests that images
contextualized in video or on its own can help to reinforce language learning, provided the learner can see immediate meaning in terms of vocabulary
recognition. By applying YouTube video in teaching-learning process, the students
could learn by practicing the exercise given. In pronouncing words, the video pronounced word first then asked the students to repeat it. It could be done
repeatedly until the students were able to pronounce words correctly. There are some advantages of using video stated by Irina 2010. In term of pronunciation,
the students can improve their pronunciation by listening to the language of native speakers and imitating it.
While in writing words, the findings show that the students could also practice writing directly as guided by YouTube video. First, it asked students to
write word they already heard, and then checked together by watching its spelling shown on video. It is supported by the statements quoted from an article entitled
“Learning Vocabulary through Authentic Video and Subtitles” no-name, undated that in this context, authentic video and subtitles can precisely play an
important role to help learners increase and strengthen their foreign language vocabulary, given the appropriate guidance. Any well-prepared learning task

using subtitles in authentic video will encourage a better understanding and acquisition of new vocabulary.
In conclusion, the use of YouTube video was able to make the students easier in learning vocabulary. The learners who saw video pictures were able to
produce a higher percentage of acceptable vocabularies than the learners who read only the lists of vocabulary given. It is supported by Marshall 2002 who cites
the conclusion of Wiman and Mierhenry 1969, extending Dale’s “Cone Experience” that people will generally remember: 10 of what they read; 20 of
what they hear; 30 of what they see; and 50 of what they hear and see.
b. YouTube video improves classroom situation
