4. The teacher depended too much on LKS and textbook as the main source of learning which caused the teaching and learning process to
be monotonous. The teacher did not supply the students with various type of interesting activities.

facilities in the classroom were limited. There was no projector in the classroom.

problems which have been stated before would need a lot of time and a long work. It would not be feasible to do in one research for the researcher. Therefore, after
discussing the problems with the English teacher, the researcher limited the problem by conducting the research focusing on
improving students’ vocabulary mastery at grade IV of SDN Gambiranom by using wall charts.

of the problem, the problem in this research is formulated as follows: How can the
students’ vocabulary mastery on grade IV students of SD N
Gambiranom be improved by using wall charts as a media?
E. Objective of the research
The objective of this research, based on the formulation of the problem is to improve
students’ vocabulary mastery by using wall charts as a media at grade IV of SD N Gambiranom, Depok, Sleman, Yogyakarta in the academic year of

A. Theoretical Review
1. Vocabulary a.
Definition of Vocabulary
Vocabulary is all the words which exist in a particular language. Vocabulary functions as a cornerstone without which any language could
not exist. The word “vocabulary” generally represents a summary of words or their combinations in a particular language.
According to Richard 2001: 40 vocabulary is one of the obvious components of language. He adds that vocabulary is the core component in
language proficiency and provides much of the basis for how learners speak, listen, read, and write. It is the basic skill to know about the other
skill of language. According to Ur 1996: 60 vocabulary can be defined as the words
teacher teaches in the foreign language. The term ’words’ here means that the new item of vocabulary maybe more than a single word, for example,
father-in-law, police office, which are made up of two or more words but express a single definition or idea.
