3. Data Collection Instrument
This study used vocabulary profiler that can be accessed from http:www.lextutor.ca to get the data. This
Lextutor
program is an electronic tool for profiling vocabulary, created by Tom Cobb in 1999. The online program breaks down words in the text to four
classifications which are K1 1-1,000 most common words, K2 1,001-2,000 most common words, Academic Word Lists, and Off-list words.
4. Data Collection Procedures
For the data collection, the main purpose is to provide the text in form of a word document to make them compatible with the vocabulary profiler. In order to do so, this study
used Microsoft Word for the word-processing software. The transcripts of the audio-visual materials were transcribed first. However, during the transcribing process, there were some
categories of words were omitted i.e. names people’s names, brand, and places, foreign
vocabulary items, and abbreviations. Therefore, only the meaningful words to English were involved in the data analysis.
5. Data Analysis
The first step to analyse the data is accessing the vocabulary profiler. Go to http:www.lextutor.ca and then click on
Vocabprofile
. Click
VP-Classic
to get the result categorized into Laufer Nation’s 4-way sorter. Go back to the word document, copy, and
paste the text per chapter into the dialogue box provided. There is a limitation of the text i.e. 200,000 characters or 35,000 words. Finally, submit the word by clicking
SUBMIT_Window
and the program will start doing the analysis.
Lextutor
as the vocabulary profiler analyses the data automatically. The output will be presented in colours indicating the category. The categories are K1, K2, AWL, and Off-list
11 and the colour represent them respectively are blue, green, yellow, and red. This result will be
discussed to answer the first research question. For the second research question, displaying the negative vocabulary profile was done by clicking
VP negative
under the family list of each category. For the third research question, go back to the home page, click
Text Lex Compare
.
D. FINDINGS AND DISCUSSIONS
This part would attempt to present the vocabulary profile of the Academic Listening course material used. The discussion is divided into three parts. The first one is the overall
result to show the vocabulary profile of the Academic Listening course material. The second part shows the negative vocabulary and the list of vocabulary items that were not found in the
course material. The third part is the comparison of vocabulary profile between two materials used in two meetings. This last part shows the repeated and unrepeated words in the material
being compared. The result of the analysis is presented in forms of tables to show the percentage and number of words.
