RESEARCH INSTRUMENTS, DEVELOPMENT OF THE INSTRUMENTS, AND DATA COLLECTION

 * 1. Research Instruments

The instruments were the questionnaire and the guideline questions of the roundtable discussions.

The questionnaire was developed by the researcher; it has seven parts:


 * 1) General Information
 * 2) Identity and Perception of the Thai Academic Community
 * 3) Perceived English Ability
 * 4) Use of English within the Community
 * 5) Perceived Language Problems
 * 6) Perceived Language Coping Ability
 * 7) Perceived Support Needed from the University.


 * 2. Development of the Instruments

Two measures were implemented to ensure the high quality of the data collection instruments: content analysis and reliability analysis.

After reviewing the relevant literature, we constructed the questionnaire. For the analysis of the contents, we asked a panel of five EFL experts to decide each of the item within each construt. The index obtained was the ratioi between what was regarded as being relevant and necessary for the measurement of a particular construct and what was deemed to be unnecessary and irrelevant. The technique was called Content Validity Ratio or CVR, which has been widely used among researchers. Lawshe's CVR, hence, was used to determine whether the items were essential/necessary for the measurement of the designed constructed.

The CVR values range from +1 (All of the experts agree that the statement is necessary for the measurement of the construct) to -1 (They all say that the statement in question is unnecessary. Therefore, the values that are closer to +1 indicate that the experts are in agreement that the item is essential to content validity. See Appendix A for the detaled report of the analysis.

Once the content analysis was completed, the remaining items were selected to form the questionnaire. The trial was conducted to analyze its reliability.

The reliability of the constructs within the questionnaire is as the following:


 * 3. Data Collection

Quantitative Data

Quantitative data were collected from parts 1, 3, 4, 5, 6, and 7 of the questionnaire. The questionnaire was distributed through the cooperation from the graduate school of Dhurakij Pundit university.

Qualitative Data

Qualitative data were collected from two sources: (1) Data from the open-ended questions (Part 2 of the questionnaire) and (2) Data collected from the two focus group discussions.

DATA ANALYSIS
The data were analyzed using the following statistical procedures: frequency distribution, percentages (%), arithmetic mean (X), and standard deviation (SD).

First, the frequency distribution and percentages were used in the analysis of answers, concerning the general background of the participants.

Data from the open-ended questions were analyzed using the content analysis method.

Criteria for Interpreting the Findings
The following are the criteria for the interpretation of the results of the analyses. 1. Respondents' Use of English

Data analyzed were interpreted based on the following criteria.

The higher mean reflects the higher level of English use.

2. Perceived Language Problems

The higher mean reflects the higher level of language problems.

3. Perceived Language Coping Ability

The higher mean reflects the higher level of coping ability.

4. Perceived Support Needed from the University

The higher mean reflects the higher level of support needed from the university.

5. Criteria for their English proficiency

The higher mean reflects the higher level of perceived English proficiency.

ROUNDTABLE DISCUSSIONS
Two roundtable seminars were conducted. The title is: English for Graduate Study: What, Why, and How Much?

The first roundtable was the one for the MBA student participants. There were five participants and it was conducted on Sunday, August 2, 2009. The second roundtable was participated by 4 DBA students, held on Sunday, August 9, 2009. Both roundtables were conducted at DPU.

They were to illicit qualitative data to help support the findings from the questionnaires.

See Appendix 3 for the summaries of the two roundtables.

CHAPTER SUMMARY
Data were collected from two sources: questionnaires and transcribed roundtable discussions.
