The study aimed to examine the effect of using reflective listening on developing EFL adults' oral fluency. The study begins with a review of literature and previous studies dealing with reflective listening and oral fluency. The researcher prepared a list of oral fluency components as a guide for the design of the instruments. The researcher also designed a pre/post oral fluency test and a rubric. The researcher designed the proposed program. Then, she nominated a random group of course trainees who passed level 5 in the Cambridge placement test and who intended to study a conversation course (n= 30) to participate in the study and get involved in its activities. Their ages ranged from (20 to 30) years old. The experimentation took place during the month of July, 2018, at Al Maadi public library. The participants were submitted to a pre and posttest. Then, the researcher analyzed the scores both quantitatively and qualitatively. The results showed that reflective listening was highly effective in developing EFL adults' oral fluency.
