One of the practical models is Flipped Classroom (FC), which has been attracted by many teachers and researchers, especially in the K-12 education system. This study explored the effect of the online FC approach on the improvement of EFL learners' performance in high schools in Iran with a quasi-experimental design. To run the experimental study, through convenience sampling forty-three high school students were divided into an experimental group and a control group and to evaluate the efficacy of the online FC approach. The comparison of the results of experimental and control groups’ pre-test and post-test scores by an independent samples t-test revealed that incorporating the online FC approach into EFL educational context remarkably improves the EFL students' learning performance. It is significantly applicable for learning a language, especially during the Covid-19 pandemic which majority of the classes have been running online. Additionally, to manage online FC more efficiently, some suggestions are provided for teachers.</span> https://www.jrtle.ir/article_150880_7fbbb8beacc1d5e78318a846a8c1e16f.pdf
