在本文中，我们讨论了技术辅助教学的进展。不像过去那样局限于基于PowerPoint或以白板为中心的电子墨水应用程序，新的工具WriteOn允许教师使用电子墨水在Tablet PC显示屏上可见的任何应用程序上进行注释。这一工具在改善课堂教学中的信息呈现和互动性方面都是有用的。在这一领域之前的研究导致了工具的开发，这些工具是基于PowerPoint®的应用程序，或单独基于电子墨水的应用程序。有些允许演讲者在课堂上播放幻灯片和电子墨水，而另一些则只是一个演示工具。先前的应用不允许展示者注释在屏幕上显示或执行的内容，也不允许同时广播桌面屏幕活动。使用WriteOn，教师可以选择与电子墨水一起实时广播动态屏幕内容。或者，WriteOn用户可以将墨迹注释和桌面活动保存为电影文件(或单独的屏幕截图)，然后将这些文件广播给学生。接收广播演示文稿的学生可以将文件保存在他们的本地计算机上。WriteOn还能够录制演示者机器上捕获的音频，并将其与批注墨迹笔划同步。使用WriteOn，教师可以通过屏幕上的注释增强正在教授的任何概念或程序的实时体验。
In this paper, we discuss an advance in technology-aided instruction. Not limited as in the past to PowerPoint-based or white board-centered electronic ink applications, the new tool, WriteOn, allows the instructor to use electronic ink to annotate on top of any application visible on the tablet PC display screen. This tool can be useful in improving both the presentation of information as well as the interactivity in classroom instruction. Previous research in this area led to the development of tools that are PowerPoint ® -based applications, or electronic ink-based alone applications. Some allowed the presenter to broadcast slides and electronic ink to class while others are simply a presentation tool. Previous applications do not allow the presenter to annotate contents displayed or executing on the screen, nor to simultaneously broadcast the desktop screen activity. Using WriteOn, the instructor can choose to broadcast the dynamic screen contents along with electronic ink in real-time. Alternatively, the WriteOn user can save the ink annotations and desktop activity as a movie file (or individual screen captures) and then later broadcast these files to the students. Students receiving the broadcast presentation may save the file on their local machine. WriteOn is also capable of recording audio captured on the presenter’s machine and synchronize it to the annotation ink strokes. Using WriteOn, the instructor can enhance the real time experience of any concept or program being taught through annotations on the screen.
