The country's higher education system seems ripe for tech industry disruption. Student debt is out of control. Graduation rates are unacceptably low. And employers still can't find enough new recruits with the training they're looking for. 美国的高等教育体系似乎已经很成熟，可以抵御技术产业对教育的影响。但另一方面我们发现，在高等教育体系下，学生贷款高得失控，毕业率特别低，大学生接受的教育仍然不能使他们适应日后的职场需求。 Enter online learning. Specifically, Massive Open Online Courses, or MOOCs, have been heralded as a savior for students disadvantaged by an inefficient, often rigid, and increasingly pricey higher ed system. The cost advantage of recording one lecture and broadcasting it to thousands of students regardless of location is undeniable. 在这种情况下，在线教育就登场了。与低效率、刻板、费用渐长的高等教育体系相比较，大规模在线开放课程（MOOC）可谓那些处于劣势的学生的救星。毫无疑问，在线教育有诸多优势，例如录制在线课程成本相对低，而且可以同时容纳数千名身处各地的学生共同听课等等。 |
