The new interactive online educational platform openHPI, (https://openHPI.de) from Hasso Plattner Institute (HPI), offers freely accessible courses at no charge for all who are interested in subjects in the field of information technology and computer science. Since 2011, “Massive Open Online Courses,” called MOOCs for short, have been offered, first at Stanford University and then later at other U.S. elite universities. Following suit, openHPI provides instructional videos on the Internet and further reading material, combined with learning-supportive self-tests, homework and a social discussion forum. Education is further stimulated by the support of a virtual learning community. In contrast to “traditional” lecture platforms, such as the tele-TASK portal (http://www.tele-task.de) where multimedia recorded lectures are available on demand, openHPI offers didactic online courses. The courses have a fixed start date and offer a balanced schedule of six consecutive weeks presented in multimedia and, whenever possible, interactive learning material. Each week, one chapter of the course subject is treated. In addition, a series of learning videos, texts, self-tests and homework exercises are provided to course participants at the beginning of the week. The course offering is combined with a social discussion platform where participants have the opportunity to enter into an exchange with course instructors and fellow participants. Here, for example, they can get answers to questions and discuss the topics in depth. The participants naturally decide themselves about the type and range of their learning activities. They can make personal contributions to the course, for example, in blog posts or tweets, which they can refer to in the forum. In turn, other participants have the chance to comment on, discuss or expand on what has been said. In this way, the learners become the teachers and the subject matter offered to a virtual community is linked to a social learning network. / Die neue interaktive Online-Bildungsplattform openHPI (https://openHPI.de) des Hasso-Plattner-Instituts (HPI) bietet frei zugängliche und kostenlose Onlinekurse für interessierte Teilnehmer an, die sich mit Inhalten aus dem Bereich der Informationstechnologien und Informatik beschäftige¬n. Wie die seit 2011 zunächst von der Stanford University, später aber auch von anderen Elite-Universitäten der USA angeboten „Massive Open Online Courses“, kurz MOOCs genannt, bietet openHPI im Internet Lernvideos und weiterführenden Lesestoff in einer Kombination mit lernunterstützenden Selbsttests, Hausaufgaben und einem sozialen Diskussionsforum an und stimuliert die Ausbildung einer das Lernen fördernden virtuellen Lerngemeinschaft. Im Unterschied zu „traditionellen“ Vorlesungsportalen, wie z.B. dem tele-TASK Portal (http://www.tele-task.de), bei dem multimedial aufgezeichnete Vorlesungen zum Abruf bereit gestellt werden, bietet openHPI didaktisch aufbereitete Onlinekurse an. Diese haben einen festen Starttermin und bieten dann in einem austarierten Zeitplan von sechs aufeinanderfolgenden Kurswochen multimedial aufbereitete und wann immer möglich interaktive Lehrmaterialien. In jeder Woche wird ein Kapitel des Kursthemas behandelt. Dazu werden zu Wochenbeginn eine Reihe von Lehrvideos, Texten, Selbsttests und ein Hausaufgabenblatt bereitgestellt, mit denen sich die Kursteilnehmer in dieser Woche beschäftigen. Kombiniert sind die Angebote mit einer sozialen Diskussionsplattform, auf der sich die Teilnehmer mit den Kursbetreuern und anderen Teilnehmern austauschen, Fragen klären und weiterführende Themen diskutieren können. Natürlich entscheiden die Teilnehmer selbst über Art und Umfang ihrer Lernaktivitäten. Sie können in den Kurs eigene Beiträge einbringen, zum Beispiel durch Blogposts oder Tweets, auf die sie im Forum verweisen. Andere Lernende können diese dann kommentieren, diskutieren oder ihrerseits erweitern. Auf diese Weise werden die Lernenden, die Lehrenden und die angebotenen Lerninhalte in einer virtuellen Gemeinschaft, einem sozialen Lernnetzwerk miteinander verknüpft.

The new interactive online educational platform openHPI, (https://openHPI.de) from Hasso Plattner Institute (HPI), offers freely accessible courses at no charge for all who are interested in subjects in the field of information technology and computer science. Since 2011, “Massive Open Online Courses,” called MOOCs for short, have been offered, first at Stanford University and then later at other U.S. elite universities. Following suit, openHPI provides instructional videos on the Internet and further reading material, combined with learning-supportive self-tests, homework and a social discussion forum. Education is further stimulated by the support of a virtual learning community. In contrast to “traditional” lecture platforms, such as the tele-TASK portal (http://www.tele-task.de) where multimedia recorded lectures are available on demand, openHPI offers didactic online courses. The courses have a fixed start date and offer a balanced schedule of six consecutive weeks presented in multimedia and, whenever possible, interactive learning material. Each week, one chapter of the course subject is treated. In addition, a series of learning videos, texts, self-tests and homework exercises are provided to course participants at the beginning of the week.

Distance education is, by its very nature, a response to the development of communications technology in the Industrial Era, coupled with the societal changes initiated by these developments (Garrison and Cleveland-Innes, 2010: 14). The current distance learning landscape is thus shaped by changing social needs brought about by the impact of advancements in technology. This case study investigates the effectiveness of new aspects of digital learning tools as additional resources in the TEFLA course, a Short Learning Programme (SLP), offered by UNISA. These aspects of digital course delivery introduce e-learning by incorporating synchronous and asynchronous digital teaching and learning tools, in the shape of MOOCs (asynchronous learning), as well as webinars (synchronous learning). This study reviews the effectiveness of these online tools in enhancing the learning experience of TEFLA students. The theoretical framework that informs this study is based on the connectivism and socio-cultural theories of knowledge acquisition. / English Studies / M.A. (English)

The advent of Massive Open Online Courses (MOOCs) allows massive volume of registrants to enrol in these MOOCs. This research aims to offer MOOCs registrants with automatic content related feedback to fulfil their cognitive needs. A framework is proposed which consists of three modules which are the subject ontology learning module, the short text classification module, and the question answering module. Unlike previous research, to identify relevant concepts for ontology learning a regular expression parser approach is used. Also, the relevant concepts are extracted from unstructured documents. To build the concept hierarchy, a frequent pattern mining approach is used which is guided by a heuristic function to ensure that sibling concepts are at the same level in the hierarchy. As this process does not require specific lexical or syntactic information, it can be applied to any subject. To validate the approach, the resulting ontology is used in a question-answering system which analyses students' content-related questions and generates answers for them. Textbook end of chapter questions/answers are used to validate the question-answering system. The resulting ontology is compared vs. the use of Text2Onto for the question-answering system, and it achieved favourable results. Finally, different indexing approaches based on a subject's ontology are investigated when classifying short text in MOOCs forum discussion data; the investigated indexing approaches are: unigram-based, concept-based and hierarchical concept indexing. The experimental results show that the ontology-based feature indexing approaches outperform the unigram-based indexing approach. Experiments are done in binary classification and multiple labels classification settings . The results are consistent and show that hierarchical concept indexing outperforms both concept-based and unigram-based indexing. The BAGGING and random forests classifiers achieved the best result among the tested classifiers.

The purpose of this research was to determine how MOOCs (Massive Open Online Courses) can be introduced and implemented in Higher Education institutions in Mauritius. The study explored the perspectives of students, teachers and educational leaders using an exploratory case study approach, and involved the implementation of short MOOC-based courses in three areas of higher education in Mauritius. While much of the existing literature on MOOCs has used quantitative data to explore patterns of enrolment and retention, this study explicitly focused on student experience, and used Garrison, Anderson and Archer’s (2000) Community of Inquiry (COI) model to explore patterns of ‘presence’ and pedagogical preferences and needs of learners. In order to explore how these preferences, together with other contextual factors might affect the adoption of MOOCs in Mauritius, Venkatesh and Davis’s (2000) Technology Acceptance Model2 (TAM2) was used. The COI and TAM2 models were used both as analytical frameworks, but also to develop a new composite model that also can function as a boundary object (Bowker and Star, 1999; Fox, 2011) enabling different stakeholders to understand each other’s needs and expectations and communicate better with each other. For Mauritian learners, teaching presence in online environments is of critical importance: this is reflected in different scenarios of MOOC implementation identified, and in a proposed staged model for MOOC adoption across the HE sector in Mauritius. This involves further pilots and preliminary research (stage 1), integration of MOOCs into practice (stage 2), customisation and development of MOOCs (stage 3) and a MOOC for Mauritius (stage 4), with each stage informing the implementation of subsequent stages as part of a broad action research framework. The original contributions made by the research to the knowledge base of its possible audiences include: providing models of practice for teachers and educational leaders; informing the educational leaders and policy makers about how MOOCs can be successfully implemented in Mauritius; providing detailed case studies on MOOCs to the academic audience interested in MOOCs specifically; and proposing a new composite, pedagogically-informed, technology acceptance model to those academics who are interested in online pedagogy and technology acceptance. The results of this PhD research can also inform the introduction and effective implementation of MOOCs in other less-economically developed countries.

Advocates of Massive Open Online Courses (MOOCs), a cross-cultural phenomenon that has attracted public attention throughout the world, portray them as an equalizing force in international higher education; but researchers have noted discrepancies in how learners from different countries have engaged with them. The number of MOOC learners in China is growing rapidly, and Chinese learners are enthusiastic about the unprecedented freedom they now have in selecting courses and accessing resources from the best international universities. However, they have a significantly low completion rate and may experience unique challenges about which little is known. This study took into account the diversity of MOOC learners and proposed changes to its course design to make it more inclusive for Chinese students. I used a mixed method—including document analysis, surveys, and interviews—to investigate the Chinese experience of taking Western MOOCs and also to explore the educational theories and design principles of MOOCs that have been discussed in the Western and Chinese literature. My analysis of the literature revealed issues of contextualization that may play a critical role in improving the MOOC experience for Chinese students. Drawing on theoretical educational frameworks—including motivation, community of inquiry, self-regulated learning, and social identity—my analysis of surveys and interviews identified common themes in the Chinese experience of Western MOOCs. In accordance with the results of my analysis, and also in line with interaction equivalency and situational principles, this study provided suggestions for adapting MOOCs to Chinese learners, such as enhancing content quality, improving learner–learner and learner–instructor interactions, providing social support, and collaborating with local universities and agencies in providing technical and credentialing support.

abstract: While predicting completion in Massive Open Online Courses (MOOCs) has been an active area of research in recent years, predicting completion in self-paced MOOCS, the fastest growing segment of open online courses, has largely been ignored. Using learning analytics and educational data mining techniques, this study examined data generated by over 4,600 individuals working in a self-paced, open enrollment college algebra MOOC over a period of eight months. Although just 4% of these students completed the course, models were developed that could predict correctly nearly 80% of the time which students would complete the course and which would not, based on each student’s first day of work in the online course. Logistic regression was used as the primary tool to predict completion and focused on variables associated with self-regulated learning (SRL) and demographic variables available from survey information gathered as students begin edX courses (the MOOC platform employed). The strongest SRL predictor was the amount of time students spent in the course on their first day. The number of math skills obtained the first day and the pace at which these skills were gained were also predictors, although pace was negatively correlated with completion. Prediction models using only SRL data obtained on the first day in the course correctly predicted course completion 70% of the time, whereas models based on first-day SRL and demographic data made correct predictions 79% of the time. / Dissertation/Thesis / Doctoral Dissertation Educational Technology 2017

Massive Open Online Courses (MOOCs) sind darauf ausgelegt, im tertiären Bildungsbereich den Wissenserwerb zu fördern, ohne dass die formalen Strukturen einer Ausbildungseinrichtung relevant sind. Dazu werden die Teilnehmer nicht persönlich von Dozenten betreut, sondern sind selbstgesteuert, oder werden durch kollaborative Lernmethoden aktiviert. Der Leistungszwang ist daher geringer, die Anzahl derjenigen, die Kurse abbrechen, jedoch ungleich höher. Durchschnittlich schließen maximal 10% der Teilnehmer ihren MOOC-Kurs ab.

Mass Open Online Courses have been a phenomenon in education in the past few years. Although their popularity is globaly on the rise, it is not yet clear how sustainable MOOCs really are in the long run. Lack of academic texts and non- existing set of guidelines for the design and implementation of effective and successful MOOCs is one of today's problems. The aim of this paper is to create such criteria that can assess the MOOC quality and success, and subsequently assess current MOOC approach and effectivity as well as outline steps to increase their efficacy. In the paper, I present a novel analysis method of potential MOOC efficacy indicators. Then, based on created criteria, I define the importance of lector's active role in the course, the need for clear formulation and communication of rules, goals and expectations, and the significance of setting high course standards. At the end, I suggest ways of utilizing this thesis for further research.
