I. Literature Review
Online teaching platforms have generally been described from three main aspects: hardware conditions (based on internet environment), core functionalities (support for remote teaching and learning), and presentation format (software systems). An online teaching platform is a comprehensive software system based on network architecture. Furthermore, online teaching platforms can be categorized into different types based on their functional emphasis. Chen Jingya, for instance, proposed three types: integrated online teaching platforms, network livestreaming teaching platforms, and post-tutoring online assessment tools[3]. A live streaming teaching platform is the intersection of online teaching platforms and live streaming platforms. The category of online teaching platforms includes the type of live streaming teaching platforms. Live streaming teaching platforms encompass all attributes of online teaching platforms and emphasizes live streaming functionality and synchronous interaction. Live streaming platforms, in turn, includes the type of live streaming teaching platforms. In comparison to general live streaming platforms, live streaming teaching platforms place a stronger emphasis on educational attributes. Their core function is to support remote synchronous teaching and learning with a greater emphasis on rules and order. This distinguishes them from entertainment and commercially oriented platforms like TikTok and Douyin. The user experience defined in this paper refers to the “perceptions and reactions of users throughout the entire process of using a live streaming teaching platform.” This includes all users' emotions, beliefs, preferences, perceptions, physical and psychological reactions, and behaviors that occur before, during, and after usage[4]. The core of user experience is UCD, which stands for “User-Centered Design.”
