6. Benefits of Knowing Low and High-Frequency Words
Laufer 1999 stated that classifying the high and low frequency words are principally required for educators, because it can be a useful help for them to know the current
vocabulary development stages of the students. However, educators are usually found spending time on teaching the low-frequency words and the learners will get the minimal
advantage from knowing them Laufer, 1999. Therefore, Nation 2014 suggests that learning the high frequency words will be well repaid because of the high chance of meeting
and using them. Therefore, after knowing the distinction between high and low frequency words, the teacher could emphasize more on the most common words of academic
vocabulary and design the exercises in which the students will be using the vocabulary.

7. Relevant Previous Studies
The previous study by Farjami 2014 using the vocabulary profiler was aimed to provide a specific detail about the vocabulary coverage in seven English textbooks used in
Iranian context. The researcher excluded the marginal information such as the table of content, page numbers, and the index at the end of the book but included the metatextual
information such as instructions and summaries to be analyzed. The result was presented in the form of table showing the numbers of the frequency profile of vocabulary in those seven
textbooks. From the analysis, the researcher could notice that the lexical input containing high frequency and academic vocabulary in the material should be developed.
Another study was conducted by Liontou 2015. VocabProfile 3.0 was used to examine the lexicogrammatical differences between intermediate and advanced reading
comprehension tests in Greek. The program was utilized to analyze 135 texts and the result showed Fhigh differences between those two levels. The text in the intermediate level
contained a higher proportion of unique words, whereas the advanced level is richer according to the lexical density.
The two previous studies mentioned above utilized vocabulary profiler generated by Cobb. They described the representativeness of exposure to English in the texts analyzed. In
addition, Farjami also investigated the word recycling index.
C. THE STUDY
This study was aimed to investigate the vocabulary profile of Academic Listening class material used by English Language Education Program in the Faculty of Language and
Literature in Satya Wacana Christian University. The descriptive method was chosen for this
9 study because the result of the vocabulary profile reported will aspire to describe the word
frequencies of the material.
