Abstract

Two methods are used to know the different result of students’ vocabulary mastery in this research.
Those are keyword method and root word analysis. In this research, the researcher used quasi
experiment design. The research was conducted at the second semester of English Department of
Muhammadiyah University of Metro in academic year 2015/2016. The researcher took all of the
students of second semester as the sample, 23 as the experiment class 1 and 23 were included as
experimental class 2 which were taken by using disproportionate systematic purposive sampling. In
collecting the data, the researcher used pre-test and post-test. In analyzing the data, the researcher used
non-parametric formula. After analyzing the result of data by using non-parametric formula, the
researcher gets the result of tratio is 5,096 and ttable 2,02 (on criterion 1) and 2,69 (on criterion 2). It
means that tratio is bigger than ttable, then the criterion of tratio is Ha is accepted if tratio is bigger than ttable.
So, there is the significant difference of learning vocabulary between using keyword method and root
word analysis toward students’ vocabulary mastery at the second semester of English Department of
Muhammadiyah University of Metro in academic year 2015/2016 and keyword method is more
effective than root word analysis toward students’ vocabulary mastery. Keyword method can be used
for increasing the students’ vocabulary mastery.
