During the COVID-19 pandemic, researchers faced challenges conducting data collection. However, emerging communication technologies, such as web-conferencing platforms, provided an alternative mode of data collection. Among these platforms, Zoom stands out for its functional affordances and unique features that support data collection methods, including screen-capturing, digital photography, drawing, polling, and artifact-based interviews, which attempt to reveal a child's viewpoint and ability. In this article, we explore the feasibility of using Zoom to conduct educational research by investigating the mathematical learning experience among 26 primary 1 and 2 students in Hong Kong on two topics—understanding time and addition and subtraction. Five mathematics teachers were recruited to participate in 2-month online workshops with assessments among three groups of students to understand the suitability for data collection. Based on teachers’ observations and students’ responses, our findings suggest that Zoom is a viable and effective tool for qualitative data collection. It offers a cost-effective method for researchers and educators to examine students’ mathematical performance in an online environment. We also investigate students’ perceptions of online assessment strategies, perceived usefulness of various Zoom functions, and explore the benefits and challenges teachers and students perceived throughout mathematical education using Zoom. However, several technical difficulties were encountered, such as the digital literacy gap and privacy concerns. Therefore, improving students’ digital literacy for remote learning and triangulation is important for online mathematical data collection and assessments. Copyright © 2023 The Author(s).

The shift from face-to-face teaching to emergency remote teaching has become the new normal due to the pandemic in 2020. However, little research has been conducted in Hong Kong to investigate pre-service teachers’ perceptions of the immediate adoption and delivery of online face-to-face teaching. In response to this call, the present research conducted a questionnaire survey with 48 pre-service teachers at a Hong Kong university to examine their perceptions of Zoom as a viable alternative to the suspended traditional face-to-face delivery mode of instruction. It also discussed key factors that lead to better online learning outcomes. The results showed that the participants had overall positive perceptions of Zoom-supported synchronous online education. The Zoom feature that most students considered useful was screen sharing on computers. Zoom-supported synchronous online learning benefited students by helping them to attend class meetings remotely, study course materials and content, communicate and collaborate with their instructors and classmates, and develop a sense of community and social presence. Four main factors may influence learners’ perceptions of synchronous online learning: the quality of online communication and collaboration, learning efficiency, learner autonomy and the usability of technology.
