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.
