Massive open online courses (MOOCs) are a recent approach to education, with much buzz generated around them by technology investors, educators, and the news media alike. However, despite the hype and the subsequent enrollment of millions of learners into MOOCs, the following years experienced a reversal of energy as the results of studies on the effects and costs of MOOCs began to reveal that MOOCs were not a panacea to formal educations’ challenges. Now, in 2016, as MOOCs continue to serve millions of students and there are more courses available than before, key questions persist about the efficacy, relevance, and value of MOOCs. This chapter examines the state of MOOCs between 2012 and 2016 and discusses advances in knowledge around MOOCs that have been observed from empirical research during this period. We build upon our previous review of MOOCs that was originally written in 2013 (Riel & Lawless, 2015), as a large number of studies focused on MOOC technologies, efficacy, and goals have been published in the short time between 2012 and 2016.
大规模在线开放课程(MOOCs)是最近兴起的一种教育方式,技术投资者、教育工作者和新闻媒体都对其议论纷纷。然而,尽管大肆宣传,随后有数百万学习者加入了mooc,但随着对mooc效果和成本的研究结果开始显示,mooc并不是解决正规教育挑战的灵丹妙药,在接下来的几年里,mooc的能量出现了逆转。到了2016年,随着mooc继续为数百万学生提供服务,可供选择的课程也比以往更多,关于mooc的有效性、相关性和价值的关键问题仍然存在。本章考察了2012年至2016年间mooc的状况,并讨论了在此期间通过实证研究观察到的围绕mooc的知识进展。我们在2013年对MOOC的回顾(Riel & Lawless, 2015)的基础上,在2012年至2016年的短时间内发表了大量关于MOOC技术、功效和目标的研究。

“You know, it doesn't work if you just try to copy Alphago; you have to understand it.” - Jennie Shin 2p Alphago often makes moves that pro commentators call strange, which in light of her successes may not be as daft as they seem. An analysis of one such “strange” move in a recent game with world #1 Ke Jie, made through the lens of a commonsense Go algorithm, reveals that it's not so strange after all.

“你知道,如果你只是试图复制阿尔法狗是行不通的;你必须理解它。Alphago经常下一些被专业评论员称为奇怪的棋,鉴于她的成功,这些棋可能并不像看起来那么愚蠢。在最近与世界排名第一的柯洁的一场比赛中,通过一种常识性的围棋算法分析了这样一种“奇怪”的走法,结果显示,这种走法其实并没有那么奇怪。全文PDF最好在双模式下查看,剩余奇数页。

Using the updated Google Book corpus dataset generated in July 2012, we analyze the largest available corpus of digitalized books to review social macro trends such as the secularization, politicization, economization, and mediatization of society. These familiar trend statements are tested through a comparative analysis of word frequency time-series plots for the English, French, and German language area produced by means of the enhanced Google Ngram Viewer, the online graphing tool that charts annual word counts as found in the Google Book corpus. The results a) confirm that the importance of the political system, religion, economy, and mass media features significant change in time and considerable regional differences and b) suggest that visions of economized or capitalist societies are intellectual artifacts rather than appropriate descriptions of society.
利用2012年7月更新的谷歌图书语料库数据集,我们分析了最大的数字化图书语料库,以回顾社会的宏观趋势,如社会的世俗化、政治化、经济化和媒体化。通过对英语、法语和德语地区的词频时间序列图进行比较分析,对这些熟悉的趋势进行测试,这些图是通过增强的Google Ngram Viewer生成的,这是一种在线绘图工具,可以将谷歌图书语料库中发现的年度单词计数绘制成图表。研究结果a)证实了政治制度、宗教、经济和大众传媒的重要性在时间上发生了重大变化,并存在相当大的地区差异;b)表明,经济化或资本主义社会的愿景是智力产物,而不是对社会的恰当描述。

In the wake of Snowden's revelations about National Security Agency (NSA) surveillance, demands that Internet carriers be more forthcoming about their handling of personal information have intensified. Responding to this concern, this report evaluates the data privacy transparency of forty-three Internet carriers serving the Canadian public. Carriers are awarded up to ten stars based on the public availability of information satisfying ten transparency criteria. Carriers earn few stars overall, just 92.5 out of 430, an average of two of ten possible stars. A variety of policy recommendations are provided to encourage and guide further data privacy transparency efforts in Canada as well as around the world.
随着斯诺登揭露美国国家安全局(NSA)的监控活动,要求互联网运营商在处理个人信息方面更加坦率的呼声日益高涨。针对这一问题,本报告评估了43家为加拿大公众服务的互联网运营商的数据隐私透明度。根据满足10项透明度标准的信息公开可用性,运营商被授予最高10颗星的评级。航空公司的总体得分很少,在430分中只有92.5分,在10颗星中平均只有2颗。提供了各种政策建议,以鼓励和指导加拿大以及世界各地进一步的数据隐私透明度工作。

Across the globe, daily economic, social, and political activities increasingly revolve around the use of content on the Internet. This content influences our understandings of, and interactions with, our social environment. Yet it is remarkable how little we know about the broader contexts in which much of that content in created. As such, this chapter sets out to comprehensively uncover: (1) where Internet content is being created; (2) whether the amount of content created in different places is changing over time; and (3) the ways in which landscapes of content are structured and formed. Mapping the geographic diversity and concentration of a broad variety of sources of online content is ultimately crucial to develop more informed strategies to combat digital divides and ultimately benefit those who are left out of flows of information.
在全球范围内,日常的经济、社会和政治活动越来越多地围绕着互联网内容的使用。这些内容影响着我们对社会环境的理解和与之互动。然而,值得注意的是,我们对这些内容产生的更广泛背景所知甚少。因此,本章将全面揭示:(1)互联网内容是在哪里创建的;(2)在不同地方创建的内容数量是否随时间而变化;(3)内容景观的结构和形成方式。绘制各种在线内容来源的地理多样性和集中度地图,对于制定更明智的战略来消除数字鸿沟,并最终使那些被排除在信息流之外的人受益,最终至关重要。

Understanding Social Media Logic 理解社交媒体逻辑
Pub Date : 2013-08-12 DOI: 10.17645/MAC.V1I1.70
J. V. van Dijck, T. Poell
Over the past decade, social media platforms have penetrated deeply into the mech­anics of everyday life, affecting people's informal interactions, as well as institutional structures and professional routines. Far from being neutral platforms for everyone, social media have changed the conditions and rules of social interaction. In this article, we examine the intricate dynamic between social media platforms, mass media, users, and social institutions by calling attention to social media logic—the norms, strategies, mechanisms, and economies—underpin­ning its dynamics. This logic will be considered in light of what has been identified as mass me­dia logic, which has helped spread the media's powerful discourse outside its institutional boundaries. Theorizing social media logic, we identify four grounding principles—programmabil­ity, popularity, connectivity, and datafication—and argue that these principles become increas­ingly entangled with mass media logic. The logic of social media, rooted in these grounding principles and strategies, is gradually invading all areas of public life. Besides print news and broadcasting, it also affects law and order, social activism, politics, and so forth. Therefore, its sustaining logic and widespread dissemination deserve to be scrutinized in detail in order to better understand its impact in various domains. Concentrating on the tactics and strategies at work in social media logic, we reassess the constellation of power relationships in which social practices unfold, raising questions such as: How does social media logic modify or enhance ex­isting mass media logic? And how is this new media logic exported beyond the boundaries of (social or mass) media proper? The underlying principles, tactics, and strategies may be relat­ively simple to identify, but it is much harder to map the complex connections between plat­forms that distribute this logic: users that employ them, technologies that drive them, economic structures that scaffold them, and institutional bodies that incorporate them.
在过去的十年里,社交媒体平台已经深入渗透到日常生活的机制中,影响着人们的非正式互动,也影响着制度结构和职业惯例。社交媒体远不是每个人的中立平台,它改变了社会互动的条件和规则。在本文中,我们通过关注社会媒体逻辑——规范、策略、机制和经济——来审视社会媒体平台、大众媒体、用户和社会机构之间错综复杂的动态关系。这一逻辑将根据大众媒介逻辑来考虑,大众媒介逻辑有助于将媒体的强大话语传播到其制度边界之外。将社会媒体逻辑理论化,我们确定了四个基本原则——可编程性、受欢迎程度、连通性和数据化——并认为这些原则与大众媒体逻辑日益纠缠在一起。根植于这些基本原则和策略的社交媒体逻辑,正逐渐侵入公共生活的各个领域。除了印刷新闻和广播,它还影响法律和秩序、社会行动主义、政治等等。因此,它的持续逻辑和广泛传播值得详细审查,以便更好地了解它在各个领域的影响。专注于社交媒体逻辑中起作用的战术和策略,我们重新评估了社会实践中展现的权力关系星座,提出了以下问题:社交媒体逻辑如何修改或增强现有的大众媒体逻辑?这种新媒体逻辑是如何输出到(社会或大众)媒体之外的?潜在的原则、战术和战略可能相对容易识别,但要映射分布这种逻辑的平台之间的复杂联系要困难得多:使用它们的用户、驱动它们的技术、支撑它们的经济结构和整合它们的机构。

The Journey to Teaching Online: A Case Study of Faculty Preparation and Experiences in Online Teaching 网络教学之旅:教师在线教学准备与经验的个案研究
Pub Date : 2013-07-30 DOI: 10.2139/SSRN.2303965

When Bill Gates published his book “The Road Ahead” (1995), he summarized the transformative implications of the personal computing revolution and described a future profoundly changed by the arrival of a global information super highway. Almost twenty years later, the tsunami of online programs and the MOOCs (massive online open courses) is impacting the structural integrity of post-secondary institutions and changing the competitive landscape of higher learning at an unprecedented pace. When Allen and Seaman (2013) asked the question of whether faculty acceptance of online education increased in their Sloan Consortium annual report, only 30.2% of chief academic officers believe their faculty accept the value and legitimacy of online education. This rate is even lower than the rate recorded in 2004. With an apparent widening gap between institutional strategy and faculty acceptance, each organization needs to conceptually map its road ahead. However, only an institution as a whole can decide for itself what kind of change is needed and define what constitutes evidence of lasting change. This implies a unique transformation of institutional philosophy, culture, strategy, and reward systems for faculty members. Complex adoptive system (CAS) theory (Olson & Eoyang, 2001), suggests that the most powerful organizational transformations occur not at the macro level but rather at the micro level where behaviors and changes began to emerge. Thus, instead of trying to measure, evaluate, or categorize which faculty member fits into which stage of online faculty development under which framework, this study asked four tenured faculty members to reconstruct their experiences on why they teach online, how they learn to teach online, and what factors influences their journeys to teaching online. Their narratives painted a landscape of faculty acceptance in institutions and the online learning phenomena in our society. Ultimately, their stories are really about change. By studying the “change agents” in a changing organization in a changing industry, this study is not an exercise to identify the best practices. Rather, this study hopes to inspire new ideas for new ways to conceptually frame the problem facing the faculty, the institution, and the industry in their road ahead in teaching online. The researcher hopes that this study may be used by institution leaders, faculty developers, and other faculty members to: (1) assess the level of progress of their current and future distance learning program, (2) determine how distance learning programs should be established, (3) evaluate faculty development efforts, (4) improve strategies and implementations for institutionalization of their distance education programs, including academic programming and faculty reward structure, and (5) improve online student retention and learning outcomes.
当比尔·盖茨出版他的书《未来之路》(1995)时,他总结了个人电脑革命的变革意义,并描述了全球信息高速公路的到来将深刻改变未来。近二十年后,在线课程和大规模在线开放课程(MOOCs)的海啸正在影响高等教育机构的结构完整性,并以前所未有的速度改变高等教育的竞争格局。当Allen和Seaman(2013)在他们的斯隆商学院联盟年度报告中询问教师对在线教育的接受程度是否有所增加时,只有30.2%的首席学术官认为他们的教师接受在线教育的价值和合法性。这一比率甚至低于2004年的记录。随着机构战略和教师接受度之间的差距明显扩大,每个组织都需要从概念上规划自己的前进道路。然而,只有作为一个整体的机构才能自己决定需要什么样的变革,并定义什么是持久变革的证据。这意味着对学院理念、文化、战略和教职员工奖励制度进行独特的转变。复杂适应系统(CAS)理论(Olson & Eoyang, 2001)表明,最强大的组织变革不是发生在宏观层面,而是发生在行为和变化开始出现的微观层面。因此,本研究并没有试图衡量、评估或分类哪个教师适合在哪个框架下的在线教师发展的哪个阶段,而是要求四位终身教职员工重建他们的经历,包括他们为什么在线教学,他们如何学习在线教学,以及哪些因素影响了他们的在线教学之旅。他们的叙述描绘了一幅教师在机构中的接受程度和我们社会中的在线学习现象的图景。最终,他们的故事是关于改变的。通过研究不断变化的行业中不断变化的组织中的“变革推动者”,本研究并不是确定最佳实践的练习。更确切地说,这项研究希望能激发新的想法,找到新的方法,从概念上框定教师、机构和行业在在线教学道路上面临的问题。研究人员希望这项研究可以被机构领导、教师开发人员和其他教师使用:(1)评估其当前和未来远程学习项目的进展水平,(2)确定如何建立远程学习项目,(3)评估教师发展努力,(4)改进远程教育项目制度化的策略和实施,包括学术规划和教师奖励结构,以及(5)提高在线学生保留率和学习成果。

The researcher hopes that this study may be used by institution leaders, faculty developers, and other faculty members to: (1) assess the level of progress of their current and future distance learning program, (2) determine how distance learning programs should be established, (3) evaluate faculty development efforts, (4) improve strategies and implementations for institutionalization of their distance education programs, including academic programming and faculty reward structure, and (5) improve online student retention and learning outcomes.","PeriodicalId":369795,"journal":{"name":"Writing Technologies eJournal","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116696699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper examines how the structure of a social network and the quality of information available to different agents determine the speed of social learning. To this end, we study a variant of the seminal model of DeGroot (1974), according to which agents linearly combine their personal experiences with the views of their neighbors. We show that the rate of learning has a simple analytical characterization in terms of the relative entropy of agents’ signal structures and their eigenvector centralities. Our characterization establishes that the way information is dispersed throughout the social network has non-trivial implications for the rate of learning. In particular, we show that when the informativeness of different agents’ signal structures are comparable in the sense of Blackwell (1953), then a positive assortative matching of signal qualities and eigenvector centralities maximizes the rate of learning. On the other hand, if information structures are such that each individual possesses some information crucial for learning, then the rate of learning is higher when agents with the best signals are located at the periphery of the network. Finally, we show that the extent of asymmetry in the structure of the social network plays a key role in the long-run dynamics of the beliefs.
本文研究了社会网络的结构和不同主体可获得的信息质量如何决定社会学习的速度。为此,我们研究了DeGroot(1974)开创性模型的一个变体,根据该模型,代理将他们的个人经历与其邻居的观点线性结合。我们表明,学习速率有一个简单的分析表征的相对熵的智能体的信号结构和它们的特征向量中心性。我们的特征表明,信息在整个社会网络中传播的方式对学习速度有着重要的影响。特别是,我们表明,当不同智能体信号结构的信息量在Blackwell(1953)的意义上具有可比性时,信号质量和特征向量中心性的正分类匹配将使学习速率最大化。另一方面,如果信息结构是这样的,每个个体都拥有一些对学习至关重要的信息,那么当具有最佳信号的代理位于网络的外围时,学习的速度会更高。最后,我们表明,社会网络结构的不对称程度在信念的长期动态中起着关键作用。

Writing the Stuff: Graphics Tablets, Tablet PC's, and Tablets as Feedback Tools 写东西:图像平板电脑,平板电脑和平板电脑作为反馈工具

In the past several years a number of older technologies have become more readily available and easier to use as feedback tools. Graphics tablets and tablet PC's allow for more flexible feedback in student writing by allowing instructors to write directly on student work in Word 2007 or later. The price and complexity of graphics tablet systems have declined in recent years making them readily available for professors with minimal budget impact. While still expensive the tablet PC offers flexibility in grading not offered by graphics tablets or pure tablets such as the iPad. This paper offers a comparison of these technologies, their relative strengths and weaknesses, and costs. The use of these technologies provides greater flexibility in providing student feedback and can improve the quality of the student experience in fully online and hybrid courses.
在过去的几年里,许多旧技术已经变得更容易获得,更容易作为反馈工具使用。图形平板电脑和平板电脑允许教师直接在Word 2007或更高版本中编写学生作业,从而为学生写作提供更灵活的反馈。近年来,图形平板电脑系统的价格和复杂性都有所下降,这使得教授们可以以最小的预算负担轻松获得它们。平板电脑虽然价格昂贵,但却提供了图形平板电脑或iPad等纯平板电脑无法提供的分级灵活性。本文提供了这些技术的比较,他们的相对优势和劣势,以及成本。这些技术的使用在提供学生反馈方面提供了更大的灵活性,并可以提高学生在完全在线和混合课程中的体验质量。
