A method for live streaming is provided. The method includes: displaying an online tutorial portal of a target service in a live-streaming room of an anchor account; in response to a trigger operation on the online tutorial portal, sending an online tutorial request to a server to request the anchor account to provide an online tutorial for the target service; in response to approval of the anchor account for the online tutorial request, acquiring video data by recording a current screen of a first terminal; displaying, in the live-streaming room of the anchor account, the current screen of the first terminal based on the video data; playing, in response to receiving audio data of the anchor account, the audio data of the anchor account; and acquiring audio data of a first account corresponding to the first terminal, and sending the audio data of the first account to the server.

Disclosed are various embodiments of a module publication application, interactive modules, and student user interfaces that make lectures more interactive. An instructor user interface generated by the module publication application captures a video of a lecture. Interactive modules including video segments and segment metadata are generated based on the video. A student user interface can render a presentation of the video segments and an interactive region showing questions that are related to the presentation. The questions shown in the interactive region can be updated based on a current timecode of the presentation.
