en عمومى General پژوهشي Research This study examines the effect of video recording in Google Drive as the self-assessing E-portfolio on high school EFL learners&rsquo; speaking fluency.&nbsp; To that end, a quasi-experimental comparison group research was implemented in which thirty Iranian high school EFL students were assigned either to e-portfolio or comparison groups. While the e-portfolio group assessed their own performance by keeping electronic portfolios in Google Drive, their counterparts in the comparison group presented their performance in the class. The students&rsquo; speaking fluency was assessed through both pre- and post-tests. A speaking rubric was used to get the students&rsquo; scores. The results of the independent sample t test showed that taking advantage of self-assessment through video-based e-portfolios improved the learners&rsquo; speaking fluency. The study had relevant implications for both material designers and language teachers not only to promote student speaking skills, but also to enhance students&rsquo; lifelong learning.<br> &nbsp; E-portfolios, Self-assessment, Speaking Fluency, Video recording, 49 60 http://ijreeonline.com/browse.php?a_code=A-10-585-1&slc_lang=en&sid=1 Razieh Rabbani Yekta Razieh Rabbani Yekta r_ryekta@yahoo.com 10031947532846001697 10031947532846001697 Yes Faculty of Literature and Foreign Languages, Payam Noor University, Iran Mohammad Amin Kana'ni Mohammad Amin Kana'ni aminkanani585@gmail.com 10031947532846001698 10031947532846001698 No Faculty of Literature and Foreign Languages, Payam Noor University, Iran
