Information . and Memory Clue) strategy, (30) students in the experiment group.(2) were taught vocabulary using SVES (Stephens Vocabulary Elaboration Strategy) ,while (30)in the control group, students were using regular instruction. A pre-test was administered to both experimental groups and the control group to assure that they were equivalent. All students were homogeneous in terms of their English language proficiency. To test the effectiveness of K.I.M strategy and SVES strategy in improving the first year secondary stage students' vocabulary learning in English, a pre-post vocabulary test was administered to all the study groups to compare the mean scores of the experimental groups and the control group. Findings of the study revealed that students of the experimental groups outperformed the control group students in vocabulary learning in English, the results of the post-test showed a significant improvement in the two experimental groups students' EFL vocabulary learning. Finally a number of recommendations related to the use of KIM strategy and SVES strategy, vocabulary learning and teaching were presented
