Introduction in Massive Open Online Courses (MOOCs)

Introduction in Massive Open Online Courses (MOOCs)
Massive open online courses (MOOCs) emerged approximately five years ago with the release of «Connectivism and Connective Knowledge» offered by the University of Manitoba . This first MOOC intended to provide a different type of learning experience due to it’s a typical construction (no registration, no learning objects, no assignments and no assessment and evaluation). Learners were expected to share their ideas on blogs, Twitter or other social network tools, thus utilizing the Internet as an open cultural space. This is an unusual course. It does not consist of a body of content you are supposed to remember. Rather, the learning in the course results from the activities you undertake, and will be different for each person. This type of course is called a ‘connectivist’ course and is based on four major types of activity:
  1. Aggregate
We will give you access to a wide variety of things to read, watch or play with. There will be a lot of content associated with this course, everything from relatively basic instruction to arguments and discussions to high-level interviews with experts in the field. You are NOT expected to read and watch everything. Even we, the facilitators, cannot do that. Instead, what you should do is PICK AND CHOOSE content that looks interesting to you and is appropriate for you. If it looks too complicated, don’t read it. If it looks boring, move on to the next item.
  1. Remix
Once you’ve read or watched or listened to some content, your next step is to keep track of that somewhere. How you do this will be up to you. You can keep a document on your own computer listing all the things you’ve accessed. Or, better yet, you can keep a record online somewhere. That way you will be able to share your content with other people.
  1. Repurpose
We don’t want you simply to repeat what other people have said. We want you to create something of your own. This is probably the hardest part of the process. Remember that you are not starting from scratch. Nobody ever creates something from nothing. That’s why we call this section ‘repurpose’ instead of ‘create’. We want to emphasize that you are working with materials, that you are not starting from scratch.
  1. Feed Forward
We want you to share your work with other people in the course, and with the world at large. Now to be clear: you don’t have to share. You can work completely in private, not showing anything to anybody. Sharing is and will always be your choice.

Initially, there was a lot of enthusiasm about such open formats (Stacey 2013), but this later gave rise to some disenchantment because of the abundance of material and infrastructure. As Weller (2011) points out, education and pedagogy shift from the economics of scarcity, in which there are relatively few experts to whom learners have access via physical interaction (e.g. lecture), making the best from the limited resources (experts and materials such as textbooks) to a model of abundance in which expertise is still rare. However, access to resources is now virtually unlimited, thanks to open access journals, slide, podcasts, videos and so forth .This is also indicated in the aforementioned MOOC principles because they impose moral values to learners (sharing, openness) albeit with the «opt-out clause» («you don’t have to share»).
Moreover, any instructional assistance for learners to help them master the challenges of openness and abundance are neglected, which would be especially important for novices . Not surprisingly, research has revealed an «expertise divide»  that is not atypical for online learning, but in case of MOOCs becomes more problematic given the outstanding importance of openness. In contrast to a «closed»   e-learning environment, learning in a MOOC is based on the assumption of already existing skills and not designed to compensate missing digital competencies. Meanwhile, MOOCs have become both a medium of mass instruction and a philosophy of instruction with roots going back to the earlier Open Education movement. Boven (2013) provides an account of the historical antecedents of the MOOC movement that identifies interesting parallels, such as the «studia» (Studium generale) in medieval Europe. The studia did not have formal and central administration controlling admission, matriculation, and commencement. Instead, masters with a reputation as scholars and teachers attempted to attract students from local communities («studia particulare») and from across Europe («studia generale»). Although not massive in terms of today’s understanding and also not in scale due to technological limitations, these early learning forms entail core educational values of MOOCs, namely the non-hierarchical exchange of ideas between teacher and learner on an individual autonomous level and the belief in the power to be guided by a master through the seven liberal arts. In a similar vein, Peter and Deimann (2013) reconstruct the role of openness for education by reviewing major trends over such as student driven education, open teaching and self-education, and the right access to knowledge. In their conclusion it is emphasized that, throughout the centuries there has been a strong connection between socio-technological improvements and increased opportunities for teaching and learning. This pertains not only to institutional settings but also to self-organized forms. Today this is reflected in virtual learning spaces such as Peer-To-Peer-University or Open Study, which offer free courses and an open platform for international study groups. However, a similar strong alliance between students and teachers that had occurred during the Late Middle Ages has not yet emerged. There is a rather loose connection in the Massive Open Online Courses given the very low formal structure. On the other side, iTunesU can be regarded as a digital resemblance of the historic practice of inviting scholars/lecturers to a group of students.

Introduction in Educational Technology (1)

Introduction in Educational Technology (1)

First, I believe that instructional technology works. Instructional technology only works for some kids, in some topics, and under some conditions, but that is true of all pedagogy, all systems for teaching or learning. There is nothing that works for every purpose, for every learner and all the time. Dale Mann (1999
The overriding message that can be gleaned from most current research on the implementation of computer-based technology in education is that technology is a means, not an end; it is a tool for achieving instructional goals, not a goal in itself. And yet, many schools and districts have invested in computer-based technology before establishing clear plans for how to use this important tool.
In today’s world, computer-based technology is not a frill, but an important component of any modern curriculum. During the last decade, technology expenditures tripled in schools in the United States; estimates suggest that over $6 billion was spent in1999-2000. Since no one wants these funds to be wasted, educators need insight into how to maximize the positive impact of their technology. This paper is for educators and policymakers who want to learn from the research and experiences of others about how to make their technology investment a wise one.
To address this issue, we summarize major research findings related to technology use and, based on these findings, attempt to draw out implications for how to make the most of technology resources. This paper will focus on pedagogical and policy issues related to technology, not smaller issues such as what hardware configurations or software to use. This is not a “how to” paper, but rather a paper about the key policy issues to be addressed in order to make technology use the most effective.
Rather than attempting a comprehensive review of the literature, this paper draws on a selection of research studies. We tried to choose studies that were the most methodologically sound. We favored those that were longitudinal, examining change over time, such as Apple Classrooms of Tomorrow (ACOT),West Virginia’s Basic Skills/Computer Education Program, and IBM’s Reinventing Education program. Other sources include numerous papers and reports from such organizations as the Milken Family Foundation, RAND Corporation, Educational Testing Service, California Research Bureau, Institute for Research on Learning, and the North Central Regional Educational Laboratory. We have identified general lessons learned from this body of current literature representing a wide range of attempts to implement technology in classrooms from 1993 to the present. We also chose studies with an eye toward illuminating the differences between “instruction” and “construction.” We believe that, compared to more didactic approaches, constructivist or student-centered approaches are better suited to fully realizing the potential of computer-based technology. Our review of the research is guided by this perspective.

THINGS YOU SHOULD KNOW ABOUT MOOCs

1. What is it?
As its name suggests, a massively open online course (MOOC) is a model for delivering learning content online to virtually any person—with no limit on attendance—who wants to take the course. Participants can be students enrolled at the institution hosting the MOOC or anyone with Internet access. The “open” students, who pay nothing to participate, can join in some or all of the course activities, which might include watching videos, posting on discussion boards and blogs, and commenting via social media platforms, though anything hosted by the institution’s LMS would likely be off-limits. Although “open” participants receive no credit for the course and may get little or no direct feedback from the instructor, their involvement can add a dynamic to the course that benefits all students. While a MOOC might accommodate enrollment in the thousands, some of these courses enroll far fewer—the “massive” part of the name speaks more to the potential to include vast numbers of students than to the actual size of the class.
2. How does it work?
Although the curriculum for a MOOC might be identical to that of a standard course, learning activities are typically restructured to better match the dynamic of a large and fluid group of participants. Course activities could be scheduled or asynchronous, and a flexible structure is valuable. A MOOC is typically hosted on easily accessible sites such as a wiki, blog, or a Google site. In addition, course interactions might take place in blogs, tweets, and other public, online venues. Public announcements regarding the course are generally made on blogs, academic websites, or professional organizations. Open students register online so that they can receive information and announcements.
3. Who’s doing it?
In 2008, George Siemens and Stephen Downes co-taught a class thought to be the first to use the term MOOC. The course, called “Connectivism and Connective Knowledge,” was presented to 25 tuition-paying students at the University of Manitoba and offered at the same time to around 2,300 students from the general public who took the online class at no cost. Since that time, most MOOCs have been taught on subjects in the education or technology spheres, but a few topics have been designed for wider appeal. Students in both groups set up online spaces, told their stories, and published them using assorted digital media. To date, those MOOCs that have drawn the largest crowds have been taught by high-profile instructors on popular topics. A recent MOOC at Stanford University, “Introduction to Artificial Intelligence,” taught by AI experts Sebastian Thrun and Peter Norvig, drew a world-wide open enrollment well in excess of 100,000 students.
4. Why is it significant?
A MOOC throws open the doors of a course and invites anyone to enter, resulting in a new learning dynamic, one that offers remarkable collaborative and conversational opportunities for students to gather and discuss the course content. To manage the often extremely large student base, instructors sometimes depend on social media tools to foster collaborative, participatory, and peer-to-peer learning. Such an approach has the benefit of distributing responsibility for teaching throughout the class rather than laying it wholly on the instructor. Because participants can include degree-seeking students, vocational learners, and people of all ages and locations, the course benefits from a rich diversity of ideas arising from many regions, cultures, and perspectives. At the same time, the MOOC allows the hosting college or university to open its curriculum to a wider audience, extending the institution’s voice into the community at large as it removes barriers to learning.

5. What are the downsides?
The dynamic of a MOOC will likely make some students uneasy, particularly those who expect or thrive on a high level of contact with the instructor. A MOOC can be energetic and nonlinear, frequently presenting students with multiple data streams from discussion boards, Twitter, Google+, Ning, and any number of other online sources. The resulting high level of noise from simultaneous conversations can overload some learners. The open character of the MOOC, which offers so much opportunity, leaves it more vulnerable to inappropriate behavior, a problem that might be exacerbated where students have no financial stake in the course. At the same time, instructors need to rethink at least some of the elements of the course to take advantage of the benefits of a MOOC, giving consideration to the technical logistics and to the structural demands of a course with such a potentially large and diverse group of participants. Some courses, for example, have struggled to provide synchronous learning opportunities when large numbers of students attend. Student access can vary with connectivity and providers, which may limit the material that can be downloaded or watched in real time. And the distributed and networked technologies employed may be unfamiliar to participants, obliging them to negotiate a technical learning curve before they can focus on course content.
6. Where is it going?
The MOOC is an emerging model, presenting an intriguing set of challenges and opportunities for both instructors and students. As it evolves, expectations and methods of presentation will likely crystallize, becoming more consistent and more predictable. Because these open classes allow prospective students to sample what a sponsoring university has to offer, MOOCs may be used as outreach tools to boost future enrollment. Moreover, these widely attended courses can and sometimes do generate significant buzz, and their potential to raise the profile of instructor and institution is unlikely to be ignored. Certainly as MOOCs develop, the scale on which these courses can be taught and the diversity of students they serve will offer institutions new territory to explore in opening their content to a wider audience and extending their reach into the community.
7. What are the implications for teaching and learning?
For the independent, lifelong learner, the MOOC presents a new opportunity to be part of a learning community, often led by key voices in education. It proves that learning happens beyond traditional school-age years and in a specific kind of room. Its low barrier to entry invites those who may lack the confidence to attend for-credit classes and those who cannot afford more traditional college opportunities. By providing a no-risk option for learning, MOOCs also encourage participation from those who lack time because someone facing a job change, a move to a new residence, or an upcoming project deadline has little to lose if they find they must end their participation midway through the course. But perhaps the most significant contribution is the MOOC’s potential to alter the relationship between learner and instructor and between academe and the wider community by potentially providing a very large and diverse forum and meeting place for ideas. Those enrolling in a MOOC are likely to discover learning at its most open on a platform that invites the world not only to see.
