result of those studies showed that after giving the treatment the vocabulary mastery of students are increased. While those previous studies have explored the
various teaching technique and media use d to teach vocabulary mastery that show high degree of motivation from students. Because those of previous studies
have not explored the use of mime story technique in vocabulary mastery, I initiatively use mime story technique in teaching vocabulary mastery, through
mime story technique students can easily remember the vocabulary because they learn with body movements. I conducted the research titled “The Effect of Mime
Story Technique in Students Vocabulary Mastery of Surrounding Objects”. This research determined whether there was a significant difference in the
achievement before and after treatment by using mime story technique and found out the effect of using mime story technique in students’ vocabulary mastery.

CHAPTER III RESEARCH METHOD
This chapter discussed several things such as research design, population and sample, hypothesis, instrument to collect the data, data collection technique,
data analysis procedure and testing hypothesis.
A. Research Design
This method use experimental reserach. Experimental is the best of the quantitative designs which is used to decide probable cause effect.
1
Experimental research is the way to find a causal relationship relationship clause in
determining cause and effect. The experimental research design is classified into pre-experimental
design, true experimental, and quasi-experimental. Pre-experimental research does not have random assignment of objects to groups or other strategies to control
extraneous variables. True-experimental research use randomization and provides maximum control of extraneous variables. Whether quasi-experimental research
lack randomization but employ other strategies to provide some control over extraneous variables.
2
In this research, the researcher used pre-experimental research. Pre-experiment research involved only one group which was pretested,
exposed to treatment, and post tested. The success of the treatment was determined by comparing the pretest and the posttest score.

The researcher gave treatment to the student. Before and after treatment, students were tested using pre-test and post test. These tests will chose as they
were available. To know the effect of mime story technique in students vocabulary mastery, the scores of pre-test and post-test were compared. If the
result of the pos-test after the treatment was higher than the pre-test, it means that mime story technique has affected the students’ vocabulary mastery. The research
design is as follows:

X2: Post-test X: Treatment
