The integration of online education is crucial in modern education, with the DingTalk platform being a popular choice among teachers. However, limited empirical research has explored students' perceptions of DingTalk. Therefore, this study employs qualitative and quantitative approaches to investigate students' perceptions of the DingTalk system characteristics. The quantitative analysis involves 250 participants and utilizes regression analysis to assess the relationship between the features of the DingTalk system and students' perceived ease of use, perceived usefulness, and continuance intention to use, indicating that it significantly influences students' perceived ease of use, perceived usefulness, and continuance intention to use. The qualitative analysis involves semi-structured interviews with a randomly selected sample of six individuals. These interviews provide in-depth insights into students' perceptions of the DingTalk system features. The findings of this study have significant implications for educators, policymakers, and other interested stakeholders.
