ABSTRACT
This paper proposes a way to construct web-based lecture materials. This material proceeds automatically based on the audio playback. Because of COVID-19, many classes become online lecture. There are several types of online lecture, such as real-time online lecture, video lecture and so on. We focus on video lecture. A video of a lecture is large files. Therefore, video streaming puts strain on the Internet. Depending on the home Internet environment, it is difficult for a student to take a lecture. To reduce a file size, our proposed method synchronizes a playing voice data and page transition of a web page. Students can take the same lecture as the video by transitioning the web pages with the voice playback. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
This paper describes a programming environment for classes of our university. It consists of a web server software at the front end and a virtual machine at the back end. Using OpenID Connect technology for its authentication enables us to operate the system securely. Since the system can be accessed via a web browser, the user does not have to install any other software additionally. We will explain the configuration details as well as the result of two-month operations. © 2021, Springer Nature Switzerland AG.
