This study investigated the effect of using the Nearpod learning platform on developing English writing fluency among adult EFL learners in a blended learning environment. The researcher developed a list of writing fluency components. Based on this list, a pre- and post-writing fluency test and a rubric for evaluating the students’ writing fluency qualitatively were designed. In addition, a writing fluency program was designed using Nearpod. A purposive sample composed of 15 Egyptian EFL second year students at the faculty of Education- Ain Shams University, aged between 19 and 21, was selected to participate in the study. The participants were engaged in the program’s interactive and structured activities through the Nearpod program. Pre- and posttests were administered, and the collected data underwent both quantitative and qualitative analysis. The findings revealed that the Nearpod program had a significant positive impact on developing writing fluency of the EFL undergraduate students.
