The data was collected from 30 ESL students as the student participants of this research, from the upper and lower secondary school, Form 1 to Form 5, and 10 teacher participants teaching English language for upper and lower secondary levels with different teaching experiences. A questionnaire and an essay examination were utilized as the instruments of the study.
