The ability to speak two languages in the non-English-speaking countries is a remarkable achievement. There is a good reason to believe that bilingualism is the norm for the majority of people in the world, because 70% of the earth's population are supposed to be bilingual or multilingual. Our purpose of the study was to determine the participants' awareness of using true and false cognate words of L 1 (the first language) & L2 (the second language) in learning English. Three hundred and eighty-five selected people from 3,789 statistical population participated in 2014--2015 at three levels of A.D., B.A., and M.A. of Islamic Azad University as well as teachers of English in English educational institutions in Zanjan (Iran). Each educational level was considered as one category with the total sample calculated by using Kokran Formula, and the amount of each category was determined by using appropriate proportion and randomized categorical sampling method. The participants' age was between from 18 to 52, with a mean age of 29 years. The materials were 45 words of true and false cognate's words from 500 words by doing CVR (content validity ratio) and CVI (content validity index) (Lawshe's table with the index of 88% and 82% respectively) for being reliable and valid. ANOVA (Analysis of variance) was used for studying the effect of educational level on the rate of awareness. In other words, the awareness level has been compared in different educational levels. The results of Dankan test show that: There is no significant difference between the awareness of A.D., B.A., and M.A. levels, but there is a significant difference between the level of awareness of teachers group and the other groups (in true cognate words) and for false cognate words, there is no significant difference between the level of awareness of the four groups in this regard. 展开更多
