    Something big is up in higher education thanks to the arrival of "massive open online courses"(MOOCs), which can reach millions around the world. What most people —including university leaders—don’t yet realize is that this new way of teaching and learning, together with employers’ growing frustration with the skills of graduates, is poised to usher in a new credentialing system that may compete with college degrees within a decade. 【R1】______
    This innovation therefore has the potential to create enormous opportunities for students, employers, and star teachers even as it upends the cost structure and practices of traditional campuses.【R2】______
    Consider the first of the two converging trends. As is well known, frustration with the performance of traditional institutions is mounting. Most employers say graduates lack the skills they need. Tuition has risen far faster than inflation or household earnings for two decades. Meanwhile, the online revolution in learning is exploding. 【R3】______
    The key question is how quickly these MOOCs will offer not just a breakthrough mode of learning for the enterprising and the curious but also true credentials that students seek because employers value them. Once a sufficient infrastructure of credible exams and assessments around MOOCs is in place, we’ll enter a new world.
    In this world, students will be able to credential themselves routinely via such courses and assessments as a way to bolster their resumes. 【R4】______ Once this challenge to the monopoly of today’s accrediting institutions begins, a big part of higher education may become vulnerable to the kind of disruption the music industry experienced a decade ago, as centrally controlled and distributed albums gave way, thanks to technology, to customized playlists assembled by individuals.
    This won’t happen overnight, hut it won’t take forever, either. If a nontrivial portion of higher education is destined to be challenged this way in the next decade, what will that mean for society? And what should universities do? 【R5】______     Today these business models truly run in full range. On one end are graduate schools that charge full freight for online degrees. On the other end of the spectrum, online learning platforms may be fueling an expectation that education should be "free," with students paying o-ver time for the exams or certificates that prove their value to employers. Maybe that’s a promising model, but the notion of free could as easily prove a risky path that undermines the economics of creating new courses. That’s why L. Rafael Reif, president of the Massachusetts Institute of Technology, suggested recently that online students should pay modest fees to help the physical university sustain its mission.
[A]When assessors persuade employers that these credentials are reliable predictors of workplace success, employers will have the confidence to give job candidates "credit" for work done outside the officially accredited institutions of higher education.
[B]Still, university leaders seeking to fulfill their mission in an era of unprecedented change would do well to develop some guiding principles to shape their response.
[C]At the University of North Carolina at Chapel Hill’s Kenan-Flagler Business School, for example, tuition is more than $ 90,000 for an online MBA.
[D]This emerging delivery regime is more than just a distribution mechanism; done right, it promises students faster, more consistent engagement with high-quality content, as well as measurable results.
[E]Coursera, a for-profit venture that taps professors and lecturers from 62 universities boasts many courses with 50,000 to 100,000 users who pay nothing for access to the best professors in the world; overall, the company has more than 2. 7 million registered students, who take at least one course.
[F]The answers depend largely on what online business models and motives evolve to govern the roles of teaching talent, colleges, assessment firms, and other key players across the education landscape.
[G]Capturing the promise of this new world without losing the best of the old will require fresh ways to square radically expanded access to world-class instruction with motives to create intellectual property and scholarly communities, plus university leaders intelligent enough to shape these evolving business models while they still can.
【R1】
选项
答案D
解析 空格出现在第一段末。空格上文指出，“大型开放式网络课程”的来临会给高等教育带来一些重大变化，这种新的教学模式及雇主对毕业生技能的日益失望将会引入一个新的认证体系，该体系或许在十年内与大学学位发生竞争。空格下文(第二段)指出，这一革新拥有为学生、雇主及名师创造大量机会的潜力。空格上下文都在围绕“大型开放式网络课程”这一新生事物展开论述，由此推断空格内容也应紧扣这一话题。[D]指出，这种新兴的交付制度使用得当的话可确保学生更快更连贯地获取高质量教学内容及可测评性结果。选项入选后通过代词指代保持了话题一致：massive open onlinecourses→this new way of teaching and learning→This emerging delivery regime→This innovation；同时，该选项所述“可确保学生更快更连贯地获取高质量教学内容及可测评性结果”与下文“拥有为学生创造大量机会的潜力”存在因果关系，符合therefore的衔接功能，故为正确选项。[A]和[B]因出现了employers，credentials，higher education，university leaders而对本题有干扰。但[A]主要阐述的是资格证书的作用，these credentials为复数，是组成“大型开放式网络课程”的一部分，这与下文This innovation的指代出现了脱节，故排除。[B]则根据语义可推测该选项的下文应对someguiding principles作进一步具体介绍，与原文语境不符，故排除。
