无处不在的演示者（UP）是一个数字演示系统，它允许教师用平板电脑自发地修改准备好的幻灯片，同时自动将打印好的幻灯片存档到网络上。对于两门物理入门课，我们考察了教师准备的幻灯片类型以及他们在幻灯片上添加墨水的方式。使用方式包括：用墨水显式链接多个表示；用墨水使准备好的人物栩栩如生；准备带有少量文字或图形的幻灯片，然后在课堂上添加大量注释。此外，通过对调查和网络服务器日志的分析，我们检查了学生对系统的反应，以及学生利用存档材料的频率和方式。总的来说，学生们觉得这个系统很有价值，并且经常在网上复习报告。
Ubiquitous Presenter (UP) is a digital presentation system that allows an instructor with a Tablet PC to spontaneously modify prepared slides, while automatically archiving the inked slides on the web. For two introductory physics classes, we examine the types of slides instructors prepare and the ways in which they add ink to the slides. Modes of usage include: using ink to explicitly link multiple representations; making prepared figures dynamic by animating them with ink; and preparing slides with sparse text or figures, then adding extensive annotations during class. In addition, through an analysis of surveys and of web server logs, we examine student reaction to the system, as well as how often and in what ways students’ utilize archived material. In general, students find the system valuable and frequently review the presentations online.
