Applying Flipgrid-Based Portfolio to Improve Vietnamese EFL High School Students’ Speaking Scores

During the covid-19 pandemic, the application of electronic teaching tools has emerged more crucial than ever. This research aimed at investigating the impacts of Flipgrid-based portfolio on EFL high school students’ speaking scores and their attitude towards the use of this e-portfolio. The study involved 86 EFL high school students in Vietnam, which were divided in two groups, a control and an experimental one. The data were collected from a pre-test, a post-test, a questionnaire, and interviews. The results showed that Flipgrid-based portfolio improved significantly students’ speaking performances in terms of pronunciation and fluency. Moreover, all the participants in the experimental group expressed a positive attitude towards the use of this online platform despite some mentioned shortcoming. On the basis of the findings, many pedagogical recommendations were suggested with the hope of pushing the effective use of e-portfolio in English language teaching and learning in EFL contexts.
