In response to the COVID-19 pandemic, the education sector rapidly transitioned from traditional to online teaching. This study examines the issue of student attention loss during online teaching, analyzes the factors influencing attention loss, and proposes solutions to address the problem. A survey of 60 adult learners of Chinese as a second language revealed that attention loss was a prevalent issue during online learning. The factors affecting attention can be categorized into two aspects: internal teaching factors and external teaching factors. The internal factors primarily revolve around inadequate communication between teachers and students, while external factors are mainly attributed to network instability. Furthermore, the majority of respondents identified “discussion” as the most effective method to increase attention. Based on these findings, this paper presents practical recommendations for improving students' attention in online teaching, based on four keywords.
