classroom, whether they give attention, see the visual, read the word, touch the explanation or not.
• Students’ answer sheet There are pre-test and post-test answer sheets in this research, pretest
was given to identify the students’ vocabulary before the method applied while post-tests were given to measure the enrichment of
students’ vocabulary after applying video in English class. 2 The Quantitative Data
Test The researcher gives tests to obtain how far the result of the technique that is
used to enrich students’ vocabulary is. There are pre-test and post-test which are used to collect the data of the enrichment.
D. Data Analysis
Having collected data, the researcher then analyzed the data. The data from the observation are analyzed after the teaching process ended. The
observation focuses on how teaching and learning process runs in the classroom. The data are divided into qualitative data and quantitative data. The
qualitative data consists of the result of observation, field notes, interview, documents and photographs. To analyze qualitative data, the researcher uses
Interactive Model. Miles and Huberman 1992: p.15 say that in general, the data analysis process includes:
1. Data Reduction Data reduction refers to the process of selecting, focusing, simplifying,
abstracting, and transforming the data that appear in written-up field notes or transcriptions. Data reduction occurs continuosly throughout the life of any
qualitatively oriented project. Even before, the data are actually collected, anticipatory, data reduction is occuring as the researcher decides often without
full awareness which conceptual framework, which cases, which research questions, and which data collection approaches to choose as data collecting
proceeds. Further episodes of data reduction occur writting summaries,

coding, teasing out themes, making cluster, making partitions, writing memos. The data reduction transforming process continues after fieldwork until a final
report is completed. 2. Data Display
The second major flow of analysis activity is data display. Generically, a display is an organized, compressed, assembly of information that permits
conclusion drawing and action. As with data reduction, the creation and use of displays is not separate from analysis, it is a part of analysis and the most
usually using narrative form in order to make the verification. 3. Conclusion Drawing and Verification
The third stream of analysis activity is conclusion drawing and verification. From the start of data collection, the qualitative analyst is beginning to decide
what things mean-is nothing regularities, patterns, explanations, possible configuration, causal flows, and prepositions.
Those three streams: data reduction, data display, and conclusion drawing verification as interwoven before, during, and after data collection is
parralel form, to make up the general domain called “analysis”. The three streams can also be represented as shown below:

interview, documents, and photographs describe how the process of teaching vocabulary using optimizing YouTube videos runs in the classroom. After
studying notes of the data, she identifies progresses and advantages as well as problems and identifies possible solution in teaching vocabulary.
Then to analyze data in quantitative method, the researcher uses descriptive statistics to describe the main features of a collection of data. The aim
is to quantitatively summarize a data set, rather than being used to support inferential statements about the population. The writer uses the mean score of
every test that contains pre-test, and post-test. These are to observe whether there are significant differences between the students’ achievement before and after the
action. It can be calculated with the formula:
N x

In which: ∑x = The sum of students’ score before the action
∑y = The sum of students’ score after the action χ

CHAPTER IV RESEARCH FINDING AND DISCUSSION
This chapter presents the research findings and the discussion dealing with the problems formulated in Chapter I. This action research is conducted in
order to investigate whether and to what extent the implementation of YouTube videos can enrich the students’ vocabulary at the fifth grade of SDN Sanggrahan.
Besides, it is conducted to describe the situation of the class when the YouTube videos is applied during teaching and learning process.
A. Research Findings
The research was conducted in collaboration with the English teacher in SDN Sanggrahan. The research was conducted in two sessions. The first was
pre-research and the second was the implementation of action research. In brief, the overall process of the research can be seen in table below:

1. Pre-research
Observing teaching and learning process Interviewing students and teacher
Conducting pre-test
2. Research Implementation
Meeting 1: Explaining and Presenting YouTube video “Listen and Repeat” Meeting 2: Discussing the exercise and Presenting YouTube video
“ Which one?” Meeting 3: Modeling and Presenting YouTube video “ What do you do?”
Cycle 1
Conducting post-test 1 Meeting 1: Modeling, Disscussing the exercise and Presenting YouTube video
“ Read the sentence” Meeting 2: Discussing the exercise, Presenting YouTube video “Which one II?”
Cycle 2
Conducting post-test 2
3. Summary of Findings during the Research
The overall process of the research as summarized in Table 4.1. is described in more detailed as in the following. This section is divided into three
main parts including description of the previous situation, research implementation, and summary of findings during the research. In pre-research, the
researcher observed teaching and learning process, interviewed students and
