网络公开课，你上过吗？上完了吗？ - 网络公开课 - IT资讯网络公开课，你上过吗？上完了吗？
免费网络公开课，全新的商业模式已经培养出了若干家行业领先者。许多用户纷至沓来，渴望获得全球知名高校的免费课程，不过该领域的创业公司却发现了一个难题：学员的结课率太低，挽留住学员、让更多的学生完成一个课程，成为这个行业的一个挑战。与此同时，他们也要寻找到营收模式。
据美国科技新闻网站Recode报道，网络公开课的结课率之低，出乎意料，仅有5%的学员，能够完成一个课程，获得及格分。
免费公开课的模式诞生已经有两年，2012年曾被《纽约时报》称之为“免费公开课元年”，不过多家公司目前已经看到新的瓶颈。
为了提高学生结课率，三大公开课公司Coursera、Udacity和edX，正在想尽办法。他们也得出了一个类似的结论：希望获得课程证书的学生，学完课程的可能性更高。另外，为课程付费的学生，结课率也更高。
最近，edX公司发布了一个有关网络公开课的统计报告，在该公司全部85万名注册用户中，结课率只有5%。他们开始研究，到底哪些因素可以让学生坚持到最后。
在加州大学伯克利分校的一个计算机科学课程中，edX对学生进行了对比研究，其中发现，认证了帐户真实身份，希望获得课程证书的学生，结课率高达52%，远高于其他学生。
在斯坦福大学提供的一个科学写作课程中，在报名之前，24%的学生表示希望可以学完，但是到最后，只有2%的学生完成了课程。
据报道，Coursera公司提供了一个收费30到100美元的服务，对学生的身份进行认证，帮助他们获得课程证书，在这些学生中，完成课程的概率为74%。
据Udacity公司的CEO介绍，他们则采取了不同的方法，在课程试验中他们发现，如果公开课能够对每个学生提供一对一的主动帮助，则结课率可以从5%，迅猛提高到六成到九成。这种帮助，无疑弥补了大部分公开课沦为“课堂视频单向广播”、缺乏互动的软肋。
另外，随着公司发展，学生人数增多，公开课公司开始寻找自己的盈利模式，免费增值模式，成为一大选择，即面向多数人提供免费课程，但是向少数学生提供高端的收费服务。
Udacity最近对网站进行了改版，将私人辅导放在更重要的位置，私人辅导课程的收费大约为每个月150美元，另外该公司还和佐治亚理工学院合作，推出了一个收费7000美元的正式的硕士学位课程计划，已经接受了第一批学生。他们的目标，是让所有的学生学成之后在科技行业找到工作。
Coursera的收费则较低，不关注私人辅导。目前该公司的学生数量是最庞大的，已经拥有600万名学生，Udacity的学生人数则为160万人，edX则为180万人。
从风险投资融资上，Coursera也排名第一，已经累计融资8500万美元，Udacity则为2000万美元，edX则为6000万美元。
