Interactivity is one of the crucial factors contributing to success in foreign language learning. However, in many countries, online learning is currently being conducted to stop the spread of the Covid-19 pandemic. Therefore, it is challenging to maintain adequate interaction between students and teachers or among students. Various platforms have been employed to improve the efficiency of online interaction in the study process such as Zoom, Google Classroom, Microsoft Teams, Skype, Team Link, etc. Among those useful tools, Nearpod has emerged as an all-around solution for online teaching, particularly in English teaching since it can ensure interactivity among teachers, students, and the materials. This research aims to investigate whether Nearpod, a tool aiding online study, increases students’ interactivity in English learning. Two hundred and four freshmen at Van Lang University (VLU), Ho Chi Minh City, Vietnam, participated in this project for eleven weeks. A Mixed-method approach was used together with 2 data collection instruments: The perception of the Online Interaction Scale (a Likert questionnaire) and open-ended questions. The results indicate that the use of Nearpod boosts interaction in online English learning. The findings have a significant contribution to facilitating virtual study which is inevitable in the hazardous infection of the Covid-19 virus.
