The data were obtained from grade 10 students who were enrolled in 2012 E.C, and English teachers of grade 10 at the school using questionnaire and interview. As it was impossible to incorporate all students in this study, 113 (25%) out of the total population of 452 students were selected using simple random sampling method. Therefore, two sections with total students of113 were selected to fell the questionnaire, but one respondent did not return the questionnaire. As a result, the analysis is of the 112 respondents. Furthermore, six students were randomly selected for interview and two EFL teachers who were teaching English to the selected sections were selected for interview. The data obtained from the samples were analyzed using qualitative and quantitative techniques. The quantitative data were presented in frequency and percentage; whereas the qualitative data were presented thematically so as to consolidate the quantitative data. Finally, the findings of this study indicated that the students did not know many vocabulary learning strategies and did not think that these vocabulary learning strategies are important to increase their word power. The students employed only a few vocabulary learning strategies. Based on the findings, the researcher recommended that teachers need to create awareness about vocabulary learning strategies and should give opportunities for their students to practice different vocabulary learning strategies.enThesis
