A questionnaire, interviews, and observations were employed in this study. Initially,
a questionnaire entitled 'Dictionary Use of Thai University Students' was
completed by 39 subjects. The questionnaire consisted of 3 questions whose aim
was to find out students' dictionary ownership, preference for dictionary use,
and preference for dictionary purchase. Based on the findings of the questionnaire,
only those who reported that they possess PEDs (10 subjects) were asked
to participate in the study. Only 4 subjects expressed an interest in the study.
Therefore each of them, in an individual session, was asked to complete a
reading task. Subjects were asked to read a news article and orally reported
what the article was about. This article was taken and adapted from a BBC
website http://news.bbc.co.uk/2/hi/health/8453628.stm entitled 'Green tea
"may block lung cancer"' which discusses that drinking green tea may avoid the
risk of lung cancer.
