the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context methods of learning new efl vocabulary in complementary line? that is, if used to teach a particular vocabulary meaning, will they provide better results than when we simply use only one of the methods? having the foregoing questions in mind, the following null hypotheses were proposed: 1- there is no difference in the perfomance of the students who learn new efl vocabulary through the keyword/context methods and those who do the same job in a no-strategy condition. 2- there is no significant difference in the performance of the students using keyword method and the students using semantic-context method. 3- there is no significant difference in the performance of the students learning new efl vocabulary through simultaneous keyword/context methods and the students involved in the same task using only one of those strategies. in order to test the hypotheses, 100 subjects were selected from a large number of students majoring in various teachnical courses. they were selected upon taking a standardized test (nelson). those students scoring more than 70 and less than 30 percent were not picked out. then the subjects were administered a vocabulary test consisting of 30 items which contained the words to be taught. this test was once used as a present and once as a post-test. students were taught the target words according to a specific strategy. every 25 subjects took part in one of the groups: control group (n0-strategy condition), keyword group, context group, the combined condition (keyword/context group). after receiving the treatments, the students took the post-test after a time interval. the statistical techniques used were t-test, correlation coefficient.
