同步远程教育可以使来自不同地理或文化区域的学生和教授成为伙伴，使他们能够相互分享和学习。技术必须支持思想和材料的共享。使用迭代设计的方法，我们调查的挑战，在同步远程学习环境中，通过观察连接两个学习网站的硕士课程。通过观察、访谈和调查，我们了解到两个主要的挑战：（1）低质量的音频/视频使交互变得困难;（2）远程学习环境中的演示技术使即兴教学变得困难。我们开发和部署了一个新的远程学习系统，使用基于互联网的视频会议和基于笔式计算机的演示系统。我们在硕士课程中学习了系统使用。在课程中收集的定性数据（观察笔记，调查，访谈记录）的分析表明，技术中断增加了网站之间的分离感，而自然笔迹与幻灯片的整合增加了灵活性，并被学生和教师积极认为。
Synchronous distance education can partner students and professors from different geographic or cultural regions, allowing them to share and learn from each other. Technology must support the sharing of ideas and materials. Using an iterative design approach, we investigated challenges in synchronous distance learning environments through observation of masters-level courses connecting two learning sites. Through observations, interviews, and surveys we learned of two major challenges: (1) low-quality audio/video makes interaction difficult; and, (2) presentation technologies in distance learning environments make extemporaneous teaching difficult. We developed and deployed a new distance learning system using Internet based video conferencing and a pen computer based presentation system. We studied system use in a masters level course. Analysis of qualitative data (observation notes, surveys, interview transcripts) collected in the course suggest that technological interruptions increased the feeling of separation between the sites, while the integration of natural handwriting with slides increased flexibility and was perceived positively by students and instructors.
