At eight on Tuesday mornings, we turn on a computer at Columbia University and join in a “global classroom” with 20 other campuses around the world. A professor or a development expert somewhere gives a talk, and many hundreds of students listen in through videoconferencing.
在过去两年中所有事情都发生了变化——而且变得更好。在星期二早上八点钟，我们在哥伦比亚大学打开一台电脑并加入一个包含了全球20个校区的“全球课堂”。一位教授或者发展专家在某个地点讲课，数千名学生都可以通过视频会议聆听教诲。
