Abstract
The current study aimed at measuring the effect of using Blended Learning (BL) model on improving Saudi EFL university students' accuracy and fluency. The study was based on the premise that integrating online instruction can create an effective learning environment in which students make use of virtual methods alongside with traditional face-to-face real-life ones. The premise was juxtaposed with the need to blend a conversation course to enhance Saudi EFL students' accuracy and fluency with the help of BL techniques, which enable guided and effective tasks with timely feedback. An experimental study, adopting a pre-post test design, was conducted on a sample of sixty students from the Department of English, Prince Sattam bin Abdul-Aziz University. The analysis of students' responses to the accuracy and fluency test indicated a positive and significant effect of BL model on developing their accuracy and fluency. The test results were supported by the qualitative analysis of the students' presentations and the instructor's classroom observations. It is concluded that accuracy and fluency are more enhanced in a blended learning environment compared with the traditional face-to-face setting. This study is a valuable contribution to CALL applications in EFL contexts, because it recommends the blending of technology and online learning pedagogy.
