.Teaching Persian words based on the effect of using the first language on teaching the second language

Persian language teaching, like other foreign languages, always has problems both in the field of teaching and in the field of learning. In the same vein, this study seeks to examine the effectiveness or inefficiency of using a mother tongue or a first language in a second language class; Because in cases where the teacher is fluent in the mother tongue of the language learner, using or not using the mother tongue in the Persian language classes of the student is always acceptable. To examine this Subject: Twenty-three Persian language learners in the Persian language teaching center of Bu Ali Sina University of Hamedan were randomly selected. Chinese, Russian, Burundian and Sri Lankan nationalities were selected as the statistical population. In order to achieve the objectives of the research, a pre-test was taken to examine the homogeneity of these language learners in order to ensure that the language learners are at a level of Persian language. After the training course, a post-test of the meaning of the taught words was taken. The results obtained from the teachers also showed that they do not believe in the effect of using the first language. According to the test and the interview, it can be concluded that the use of native or first language in the Persian language class for teaching vocabulary does not affect learning and Persian language teachers do not agree that the native language of learners in the classroom , Used. The results of this study can be useful for teachers and centers of Persian language education as well as researchers in this field.
