网络“常青藤”

In March, YouTube launched an education hub called YouTube Edu, dedicated exclusively to videos from the more than 100 schools--ranging from Grand Rapids Community College to Harvard Business School--that have set up official channels on the site. Liberated from the viral stew of pop-culture vlogs and silly cat videos, the collection highlights how much free education is out there.

But producing content for global consumption can be hugely expensive. MIT, an open-courseware pioneer that since 2002 has published text materials such as lecture notes and syllabi for about 85% of its curriculum, spends more than $10,000 per course to compile, publish and license text materials; classes with videos cost twice as much.

Another new site, AcademicEarth.org lets users give lectures letter grades.

There is clearly a big appetite for all kinds of online lectures, as shown by the popularity of sites like TED.com which broadcasts talks given by innovators in the fields of technology, entertainment and design. But one of the most interesting consequences of open courseware may be its impact on teachers, who have a new way to get feedback--and exposure.

自动翻译结果:3月,YouTube推出了一个名为YouTube Edu的教育中心,专门收录100多所学校的视频--从大急流城社区学院到哈佛商学院,这些学校都在网站上建立了官方频道。从病毒式的流行文化vlogs和傻猫视频中解放出来,这个系列突出了免费教育的重要性。

但制作全球消费的内容可能非常昂贵。麻省理工学院是一个开放课程软件的先驱,自2002年以来,该学院已经发布了大约85%的课程的文本材料,如讲义和教学大纲,每门课程花费超过1万美元来编译、发布和授权文本材料;带有视频的课程成本是其两倍。

另一个新网站AcademicEarth.org可以让用户给讲课打字母等级。

显然,人们对各类在线讲座的胃口很大,这一点从TED.com等网站的受欢迎程度就可以看出,这些网站播放技术、娱乐和设计领域的创新者的演讲。但是,开放课件最有趣的后果之一可能是它对教师的影响,他们有了一种新的方式来获得反馈和曝光。 

youtube.com/edu ted.com MIT open-courseware 以及 AcademicEarth.org 这些都是很好的学习资源,只可惜在今年三月youtube Edu刚上线的时候,在中国却恰好被block了。
