The field of American Jewish studies has recently trained its focus on the transnational dimensions of its subject, reflecting in more sustained ways than before about the theories and methods of this approach. Yet, much of the insight to be gained from seeing American Jewry as constitutively entangled in many ways with other Jewries has not yet been realized. Transnational American Jewish studies are still in their infancy.
This issue of PaRDeS presents current research on the multiple entanglements of American with Central European, especially German-speaking Jewries in the 19th and 20th centuries. The articles reflect the wide range of topics that can benefit from a transnational understanding of the American Jewish experience as shaped by its foreign entanglements.
Eine Zunahme der allgemeinen Temperatur auf Grund des Klimawandels und die damit einhergehende Zunahme von Hitzewellen führten dazu, dass das Landesamt für Umwelt und Verbraucherschutz Nordrhein-Westfalen (LANUV) einen Leitfaden für den Schutz der positiven Klimafunktion urbaner Böden herausgab. Darauf aufbauend wurde auf regionaler Ebene für die Stadt Düsseldorf die Kühlleistung der urbanen Böden quantifiziert, um besonders schutzwürdige Bereiche zu identifizieren. Im Rahmen des Projektes ExTrass sollte nun die Kühlleistung urbaner Böden innerhalb Remscheids quantifiziert werden, jedoch auf Basis von frei zugänglichen Daten. Eine solche Datengrundlage schließt eine Modellierung des Bodenwasserhaushaltes, welches die Grundlage der Quantifizierung in Düsseldorf war, für Remscheid aus. Jedoch bietet der vorgestellte Ansatz die Möglichkeit, eine solche Untersuchung auch in anderen Gemeinden innerhalb Deutschlands mit relativ wenig Aufwand durchzuführen.
Die Kühlleistung der Böden wurde über die nutzbare Feldkapazität abgeschätzt, welche das Wasserspeichervolumen der obersten durchwurzelten Bodenzone angibt. Es ist der Bodenwasserspeicher, der Wasser für die Evapotranspiration zur Verfügung stellt und damit maßgeblich die Kühlleistung eines Bodens definiert, d.h. durch direkte Evaporation des Bodenwassers sowie durch die Transpiration von Wasser durch Pflanzen. In die Erstellung der Karte sind eingegangen: (a) die Bodenkarte Nordrhein-Westfalens (BK50), um die nutzbare Feldkapazität (nFK) je Fläche zu bestimmen; (b) der Landnutzungsdatensatz UrbanAtlas 2012, in Verbindung mit einer Literaturrecherche, um den Einfluss der Landnutzung auf die Werte der nFK, insbesondere im Hinblick auf Versiegelung und Verdichtung herzuleiten; und (c) OpenStreetMap (OSM), um den Anteil der versiegelten Flächen genauer zu bestimmen, als dies auf Basis des UrbanAtlas möglich gewesen wäre.
Es hat sich gezeigt, dass dieser Ansatz geeignet ist, um die räumliche Verteilung der potenziellen Bodenkühlfunktion innerhalb einer Stadt zu untersuchen. Es ist zu beachten, dass der Einfluss des Grundwassers in Remscheid nicht berücksichtigt werden konnte. Denn es ist damit zu rechnen, dass die Grundwasserverhältnisse aufgrund der geologischen und topographischen Situation in Remscheid kleinräumig Variationen unterliegen und es somit
keinen durchgängigen und kartierten Aquifer gibt.
Kleingartenanlagen, Parks und Friedhöhe im innerstädtischen Bereich und allgemein die Landnutzungsklassen Wald und Grünland wurden als Flächen mit einem besonders hohem potenziellen Bodenkühlpotenzial identifiziert. Solche Flächen sind besonders schützenswert. Die Analyse der Speicherfüllstände der oberen Bodenzone, basierend auf der erstellten Karte der potenziellen Bodenkühlfunktion und der klimatischen Wasserbilanz, ergab, dass besonders innerstädtische Flächen, die einen kleinen Bodenwasserspeicher haben, in einem trockenen Jahr bereits früh im Sommer ihre Kühlfunktion verlieren und bei Hitzewellen somit eine verringerte positive Klimafunktion haben. Gestützt wird diese Aussage durch eine Auswertung des normalisierten differenzierten Vegetationsindex (NDVI), der genutzt wurde, um die Veränderung der Pflanzenvitalität vor und nach einer Hitzeperiode im Juni/Juli 2018 zu untersuchen.
Messungen mit Meteobikes, einer Vorrichtung, die dazu geeignet ist, während einer Radfahrt kontinuierlich die Temperatur zu messen, stützen die Erkenntnis, dass innerstädtische Grünflächen wie Parks eine positive Wirkung auf das urbane Mikroklima haben. Weiterhin zeigen diese Messungen, dass die Topographie innerhalb des Untersuchungsgebietes die Aufheizung einzelner Flächen und die Temperaturverteilung vermutlich mitbestimmt. Die hier vorgestellte Karte der potenziellen Kühlfunktion für Remscheid sollte als Ergänzung in die Klimafunktionskarte für Remscheid eingehen und den bestehenden Layer „flächenhafte Klimafunktion“, der nur die Landnutzung berücksichtigt, ersetzen.
In recent years, computer vision algorithms based on machine learning have seen rapid development. In the past, research mostly focused on solving computer vision problems such as image classification or object detection on images displaying natural scenes. Nowadays other fields such as the field of cultural heritage, where an abundance of data is available, also get into the focus of research. In the line of current research endeavours, we collaborated with the Getty Research Institute which provided us with a challenging dataset, containing images of paintings and drawings. In this technical report, we present the results of the seminar "Deep Learning for Computer Vision". In this seminar, students of the Hasso Plattner Institute evaluated state-of-the-art approaches for image classification, object detection and image recognition on the dataset of the Getty Research Institute. The main challenge when applying modern computer vision methods to the available data is the availability of annotated training data, as the dataset provided by the Getty Research Institute does not contain a sufficient amount of annotated samples for the training of deep neural networks. However, throughout the report we show that it is possible to achieve satisfying to very good results, when using further publicly available datasets, such as the WikiArt dataset, for the training of machine learning models.
Das Schulfach Geographie war in der DDR eines der Fächer, das sehr stark mit politischen Themen im Sinne des Marxismus-Leninismus bestückt war. Ein anderer Aspekt sind die sozialistischen Erziehungsziele, die in der Schulbildung der DDR hoch im Kurs standen. Im Fokus stand diesbezüglich die Erziehung der Kinder zu sozialistischen Persönlichkeiten. Die Arbeit versucht einen klaren Blick auf diesen Umstand zu werfen, um zu erfahren, was da von den Lehrkräften gefordert wurde und wie es in der Schule umzusetzen war.
Durch den Fall der Mauer war natürlich auch eine Umstrukturierung des Bildungssystems im Osten unausweichlich. Hier will die Arbeit Einblicke geben, wie die Geographielehrkräfte diese Transformation mitgetragen und umgesetzt haben. Welche Wesenszüge aus der Sozialisierung in der DDR haben sich bei der Gestaltung des Unterrichtes und dessen Ausrichtung auf die neuen Erziehungsziele erhalten?
Hierzu wurden Geographielehrkräfte befragt, die sowohl in der DDR als auch im geeinten Deutschland unterrichtet haben. Die Fragen bezogen sich in erster Linie auf die Art und Weise des Unterrichtens vor, während und nach der Wende und der daraus entstandenen Systemtransformation.
Die Befragungen kommen zu dem Ergebnis, dass sich der Geographieunterricht in der DDR thematisch von dem in der BRD nicht sonderlich unterschied. Von daher bedurfte es keiner umfangreichen inhaltlichen Veränderung des Geographieunterrichts. Schon zu DDR-Zeiten wurden durch die Lehrkräfte offenbar eigenmächtig ideologiefreie physisch-geographische Themen oft ausgedehnt, um die Ideologie des Faches zu reduzieren. So fiel den meisten eine Anpassung ihres Unterrichts an das westdeutsche System relativ leicht. Die humanistisch geprägte Werteerziehung des DDR-Bildungssystems wurde unter Ausklammerung des sozialistischen Aspektes ebenso fortgeführt, da es auch hier viele Parallelen zum westdeutschen System gegeben hat. Deutlich wird eine Charakterisierung des Faches als Naturwissenschaft von Seiten der ostdeutschen Lehrkräfte, obwohl das Fach an den Schulen den Gesellschaftswissenschaften zugeordnet wird und auch in der DDR eine starke wirtschaftsgeographische Ausrichtung hatte.
Von der Verantwortung sozialistische Persönlichkeiten zu erziehen, wurden die Lehrkräfte mit dem Ende der DDR entbunden und die in dieser Arbeit aufgeführten Interviewauszüge lassen keinen Zweifel daran, dass es dem Großteil der Befragten darum nicht leidtat, sie sich aber bis heute an der Werteorientierung aus DDR-Zeiten orientieren.
The noble way to substantiate decisions that affect many people is to ask these people for their opinions. For governments that run whole countries, this means asking all citizens for their views to consider their situations and needs.
Organizations such as Africa's Voices Foundation, who want to facilitate communication between decision-makers and citizens of a country, have difficulty mediating between these groups. To enable understanding, statements need to be summarized and visualized. Accomplishing these goals in a way that does justice to the citizens' voices and situations proves challenging. Standard charts do not help this cause as they fail to create empathy for the people behind their graphical abstractions. Furthermore, these charts do not create trust in the data they are representing as there is no way to see or navigate back to the underlying code and the original data. To fulfill these functions, visualizations would highly benefit from interactions to explore the displayed data, which standard charts often only limitedly provide.
To help improve the understanding of people's voices, we developed and categorized 80 ideas for new visualizations, new interactions, and better connections between different charts, which we present in this report. From those ideas, we implemented 10 prototypes and two systems that integrate different visualizations. We show that this integration allows consistent appearance and behavior of visualizations. The visualizations all share the same main concept: representing each individual with a single dot. To realize this idea, we discuss technologies that efficiently allow the rendering of a large number of these dots. With these visualizations, direct interactions with representations of individuals are achievable by clicking on them or by dragging a selection around them. This direct interaction is only possible with a bidirectional connection from the visualization to the data it displays. We discuss different strategies for bidirectional mappings and the trade-offs involved. Having unified behavior across visualizations enhances exploration. For our prototypes, that includes grouping, filtering, highlighting, and coloring of dots. Our prototyping work was enabled by the development environment Lively4. We explain which parts of Lively4 facilitated our prototyping process. Finally, we evaluate our approach to domain problems and our developed visualization concepts.
Our work provides inspiration and a starting point for visualization development in this domain. Our visualizations can improve communication between citizens and their government and motivate empathetic decisions. Our approach, combining low-level entities to create visualizations, provides value to an explorative and empathetic workflow. We show that the design space for visualizing this kind of data has a lot of potential and that it is possible to combine qualitative and quantitative approaches to data analysis.
Die vorliegende Studie zeigt, dass Daten in der Krise eine herausragende Bedeutung für die wissenschaftliche Politikberatung, administrative Entscheidungsvorbereitung und politische Entscheidungsfindung haben. In der Krise gab es jedoch gravierende Kommunikationsprobleme und Unsicherheiten in der wechselseitigen Erwartungshaltung von wissenschaftlichen Datengebern und politisch-administrativen Datennutzern. Die Wissensakkumulation und Entscheidungsabwägung wurde außerdem durch eine unsichere und volatile Datenlage zum Pandemiegeschehen, verbunden mit einer dynamischen Lageentwicklung, erschwert. Nach wie vor sind das Bewusstsein und wechselseitige Verständnis für die spezifischen Rollenprofile der am wissenschaftlichen Politikberatungsprozess beteiligten Akteure sowie insbesondere deren Abgrenzung als unzureichend einzuschätzen.
Die Studie hat darüber hinaus vielfältige Defizite hinsichtlich der Verfügbarkeit, Qualität, Zugänglichkeit, Teilbarkeit und Nutzbarkeit von Daten identifiziert, die Datenproduzenten und -verwender vor erhebliche Herausforderungen stellen und einen umfangreichen Reformbedarf aufzeigen, da zum einen wichtige Datenbestände für eine krisenbezogene Politikberatung fehlen. Zum anderen sind die Tiefenschärfe und Differenziertheit des verfügbaren Datenbestandes teilweise unzureichend. Dies gilt z.B. für sozialstrukturelle Daten zur Schwere der Pandemiebetroffenheit verschiedener Gruppen oder für kleinräumige Daten über Belastungs- und Kapazitätsparameter, etwa zur Personalabdeckung auf Intensivstationen, in Gesundheitsämtern und Pflegeeinrichtungen. Datendefizite sind ferner im Hinblick auf eine ganzheitliche Pandemiebeurteilung festzustellen, zum Beispiel bezüglich der Gesundheitseffekte im weiteren Sinne, die aufgrund der ergriffenen Maßnahmen entstanden sind (Verschiebung oder Wegfall von Operationen, Behandlungen und Prävention, aber auch häusliche Gewalt und psychische Belastungen). Mangels systematischer Begleitstudien und evaluativer Untersuchungen, u.a. auch zu lokalen Pilotprojekten und Experimenten, bestehen außerdem Datendefizite im Hinblick auf die Wirkungen von Eindämmungsmaßnahmen oder deren Aufhebung auf der gebietskörperschaftlichen Ebene.
Insgesamt belegt die Studie, dass es zur Optimierung der datenbasierten Politikberatung und politischen Entscheidungsfindung in und außerhalb von Krisen nicht nur darum gehen kann, ein „Mehr“ an Daten zu produzieren sowie deren Qualität, Verknüpfung und Teilung zu verbessern. Vielmehr müssen auch die Anreizstrukturen und Interessenlagen in Politik, Verwaltung und Wissenschaft sowie die Kompetenzen, Handlungsorientierungen und kognitiv-kulturellen Prägungen der verschiedenen Akteure in den Blick genommen werden. Es müssten also Anreize gesetzt und Strukturen geschaffen werden, um das Interesse, den Willen und das Können (will and skill) zur Datennutzung auf Seiten politisch-administrativer Entscheider und zur Dateneinspeisung auf Seiten von Wissenschaftlern zu stärken. Neben adressatengerechter Informationsaufbereitung geht es dabei auch um die Gestaltung eines normativen und institutionellen Rahmens, innerhalb dessen die Nutzung von Daten für Entscheidungen effektiver, qualifizierter, aber auch transparenter, nachvollziehbarer und damit demokratisch legitimer erfolgen kann.
Vor dem Hintergrund dieser empirischen Befunde werden acht Cluster von Optimierungsmaßnahmen vorgeschlagen:
(1) Etablierung von Datenstrecken und Datenteams,
(2) Schaffung regionaler Datenkompetenzzentren,
(3) Stärkung von Data Literacy und Beschleunigung des Kulturwandels in der öffentlichen Verwaltung,
(4) Datenstandardisierung, Interoperabilität und Registermodernisierung,
(5) Ausbau von Public Data Pools und Open Data Nutzung,
(6) Effektivere Verbindung von Datenschutz und Datennutzung,
(7) Entwicklung eines hochfrequenten, repräsentativen Datensatzes,
(8) Förderung der europäischen Daten-Zusammenarbeit.
The COVID-19 pandemic emergency has forced a profound reshape of our lives. Our way of working and studying has been disrupted with the result of an acceleration of the shift to the digital world. To properly adapt to this change, we need to outline and implement new urgent strategies and approaches which put learning at the center, supporting workers and students to further develop “future proof” skills. In the last period, universities and educational institutions have demonstrated that they can play an important role in this context, also leveraging on the potential of Massive Open Online Courses (MOOCs) which proved to be an important vehicle of flexibility and adaptation in a general context characterised by several constraints. From March 2020 till now, we have witnessed an exponential growth of MOOCs enrollments numbers, with “traditional” students interested in different topics not necessarily integrated to their curricular studies. To support students and faculty development during the spreading of the pandemic, Politecnico di Milano focused on one main dimension: faculty development for a better integration of digital tools and contents in the e-learning experience. The current discussion focuses on how to improve the integration of MOOCs in the in-presence activities to create meaningful learning and teaching experiences, thereby leveraging blended learning approaches to engage both students and external stakeholders to equip them with future job relevance skills.
Clustering in education is important in identifying groups of objects in order to find linked patterns of correlations in educational datasets. As such, MOOCs provide a rich source of educational datasets which enable a wide selection of options to carry out clustering and an opportunity for cohort analyses. In this experience paper, five research studies on clustering in MOOCs are reviewed, drawing out several reasonings, methods, and students’ clusters that reflect certain kinds of learning behaviours. The collection of the varied clusters shows that each study identifies and defines clusters according to distinctive engagement patterns. Implications and a summary are provided at the end of the paper.
MOOCs have been produced using a variety of instructional design approaches and frameworks. This paper presents experiences from the instructional approach based on the ADDIE model applied to designing and producing MOOCs in the Erasmus+ strategic partnership on Open Badge Ecosystem for Research Data Management (OBERRED). Specifically, this paper describes the case study of the production of the MOOC “Open Badges for Open Science”, delivered on the European MOOC platform EMMA. The key goal of this MOOC is to help learners develop a capacity to use Open Badges in the field of Research Data Management (RDM). To produce the MOOC, the ADDIE model was applied as a generic instructional design model and a systematic approach to the design and development following the five design phases: Analysis, Design, Development, Implementation, Evaluation. This paper outlines the MOOC production including methods, templates and tools used in this process including the interactive micro-content created with H5P in form of Open Educational Resources and digital credentials created with Open Badges and issued to MOOC participants upon successful completion of MOOC levels. The paper also outlines the results from qualitative evaluation, which applied the cognitive walkthrough methodology to elicit user requirements. The paper ends with conclusions about pros and cons of using the ADDIE model in MOOC production and formulates recommendations for further work in this area.
Aside from providing instructional materials to the public, developing massive open online courses (MOOCs) can benefit institutions in different ways. Some examples include providing training opportunities for their students aspiring to work in the online learning space, strengthening its brand recognition through courses appealing to enthusiasts, and enabling online linkages with other universities. One such example is the monozukuri MOOC offered by the Tokyo Institute of Technology on edX, which initially presented the Japanese philosophy of making things in the context of a mechanical engineering course. In this paper, we describe the importance of involving a course development team with a diverse background. The monozukuri MOOC and its revision enabled us to showcase an otherwise distinctively Japanese topic (philosophy) as an intersection of various topics of interest to learners with an equally diverse background. The revision resulted in discussing monozukuri in a mechanical engineering lesson and how monozukuri is actively being practiced in the Japanese workplace and academic setting while juxtaposing it to the relatively Western concept of experiential learning. Aside from presenting the course with a broader perspective, the revision had been an exercise for its team members on working in a multicultural environment within a Japanese institution, thus developing their project management and communication skills.
Learning During COVID-19
(2021)
During the COVID-19 pandemic, learning in higher education and beyond shifted en masse to online formats, with the short- and long-term consequences for Massive Open Online Course (MOOC) platforms, learners, and creators still under evaluation. In this paper, we sought to determine whether the COVID-19 pandemic and this shift to online learning led to increased learner engagement and attainment in a single introductory biology MOOC through evaluating enrollment, proportional and individual engagement, and verification and performance data. As this MOOC regularly operates each year, we compared these data collected from two course runs during the pandemic to three pre-pandemic runs. During the first pandemic run, the number and rate of learners enrolling in the course doubled when compared to prior runs, while the second pandemic run indicated a gradual return to pre-pandemic enrollment. Due to higher enrollment, more learners viewed videos, attempted problems, and posted to the discussion forums during the pandemic. Participants engaged with forums in higher proportions in both pandemic runs, but the proportion of participants who viewed videos decreased in the second pandemic run relative to the prior runs. A higher percentage of learners chose to pursue a certificate via the verified track in each pandemic run, though a smaller proportion earned certification in the second pandemic run. During the pandemic, more enrolled learners did not necessarily correlate to greater engagement by all metrics. While verified-track learner performance varied widely during each run, the effects of the pandemic were not uniform for learners, much like in other aspects of life. As such, individual engagement trends in the first pandemic run largely resemble pre-pandemic metrics but with more learners overall, while engagement trends in the second pandemic run are less like pre-pandemic metrics, hinting at learner “fatigue”. This study serves to highlight the life-long learning opportunity that MOOCs offer is even more critical when traditional education modes are disrupted and more people are at home or unemployed. This work indicates that this boom in MOOC participation may not remain at a high level for the longer term in any one course, but overall, the number of MOOCs, programs, and learners continues to grow.
CoFeeMOOC-v.2
(2021)
Providing adequate support to MOOC participants is often a challenging task due to massiveness of the learners’ population and the asynchronous communication among peers and MOOC practitioners. This workshop aims at discussing common learners’ problems reported in the literature and reflect on designing adequate feedback interventions with the use of learning data. Our aim is three-fold: a) to pinpoint MOOC aspects that impact the planning of feedback, b) to explore the use of learning data in designing feedback strategies, and c) to propose design guidelines for developing and delivering scaffolding interventions for personalized feedback in MOOCs. To do so, we will carry out hands-on activities that aim to involve participants in interpreting learning data and using them to design adaptive feedback. This workshop appeals to researchers, practitioners and MOOC stakeholders who aim to providing contextualized scaffolding. We envision that this workshop will provide insights for bridging the gap between pedagogical theory and practice when it comes to feedback interventions in MOOCs.
There are a plethora of ways to guide and support people to learn about MOOC (massive open online course) development, from their first interest, sourcing supportive resources, methods and tools to better aid their understanding of the concepts and pedagogical approaches of MOOC design, to becoming a MOOC developer. This contribution highlights tools and methods that are openly available and re-usable under Creative Commons licenses. Our collection builds upon the experiences from three MOOC development and hosting teams with joint experiences of several hundred MOOCs (University of Applied Sciences in Lübeck, Graz University of Technology, University of Glasgow) in three European countries, which are Germany, Austria and the UK. The contribution recommends and shares experiences with short articles and poster for first information sharing a Monster MOOC assignment for beginners, a MOOC canvas for first sketches, the MOOC design kit for details of instructional design and a MOOC for MOOC makers and a MOOC map as introduction into a certain MOOC platform.
Universitat Politècnica de València’s Experience with EDX MOOC Initiatives During the Covid Lockdown
(2021)
In March 2020, when massive lockdowns started to be enforced around the world to contain the spread of the COVID-19 pandemic, edX launched two initiatives to help students around the world providing free certificates for its courses, RAP, for member institutions and OCE, for any accredited academic institution. In this paper we analyze how Universitat Poltècnica de València contributed with its courses to both initiatives, providing almost 14,000 free certificate codes in total, and how UPV used the RAP initiative as a customer, describing the mechanism used to distribute more than 22,000 codes for free certificates to more than 7,000 UPV community members, what led to the achievement of more than 5,000 free certificates. We also comment the results of a post initiative survey answered by 1,612 UPV members about 3,241 edX courses, in which they communicated a satisfaction of 4,69 over 5 with the initiative.
Massive Open Online Courses (MOOCs) offer online courses at low cost for anyone with an internet access. At its early days, the MOOC movement raised the flag of democratizing education, but soon enough, this utopian idea collided with the need to find sustainable business models. Moving from open access to a new financially sustainable certification and monetization policy in December 2015 we aim at this change-point and observe the completion rates before and after this monetary change. In this study we investigate the impact of the change on learners from countries of different development status. Our findings suggest that this change has lowered the completion rates among learners from developing countries, increasing gaps that already existed between global learners from countries of low and high development status. This suggests that more inclusive monetization policies may help MOOCs benefits to spread more equally among global learners.
This paper aims to present the results of a higher education experience promoted by the research centres INTELLECT (University of Modena and Reggio Emilia) and CDM (University of Roma Tre), as part of difference master’s degrees programme of the academic years 2018/2019, 2019/2020, and 2020/2021. Through different online activities, 37 students attended and evaluated a MOOC on museum education content, such promoting their professionals and transverse skills, such as critical thinking, and developing their knowledge relative to OERs, within culture and heritage education contexts. Moreover, results from the online evaluation activities support the implementation of the MOOC in a collaborative way: during the academic years, evaluation data have been used by researcher to make changes to the course modules, thus realizing a more effective online path from and educational point of view.
The MOOC-CEDIA Observatory
(2021)
In the last few years, an important amount of Massive Open Online Courses (MOOCS) has been made available to the worldwide community, mainly by European and North American universities (i.e. United States). Since its emergence, the adoption of these educational resources has been widely studied by several research groups and universities with the aim of understanding their evolution and impact in educational models, through the time. In the case of Latin America, data from the MOOC-UC Observatory (updated until 2018) shows that, the adoption of these courses by universities in the region has been slow and heterogeneous. In the specific case of Ecuador, although some data is available, there is lack of information regarding the construction, publication and/or adoption of such courses by universities in the country. Moreover, there are not updated studies designed to identify and analyze the barriers and factors affecting the adoption of MOOCs in the country. The aim of this work is to present the MOOC-CEDIA Observatory, a web platform that offers interactive visualizations on the adoption of MOOCs in Ecuador. The main results of the study show that: (1) until 2020 there have been 99 MOOCs in Ecuador, (2) the domains of MOOCs are mostly related to applied sciences, social sciences and natural sciences, with the humanities being the least covered, (3) Open edX and Moodle are the most widely used platforms to deploy such courses. It is expected that the conclusions drawn from this analysis, will allow the design of recommendations aimed to promote the creation and use of quality MOOCs in Ecuador and help institutions to chart the route for their adoption, both for internal use by their community but also by society in general.
Forschungsdatenmanagement
(2021)
Forschungsdatenmanagement ist ein informationswissenschaftliches Thema, dessen Bedeutung kontinuierlich, spätestens aber seit dem Start der Nationalen Forschungsdateninfrastruktur (NFDI) immer präsenter wird. Zur Abbildung und Verortung von Arbeitsschwerpunkten für Informationswissenschaftler*innen wurde in der vorliegenden Arbeit ein aktuelles Korpus von 162 Stellenanzeigen, in denen Forschungsdatenmanagement erwähnt wird, ausgewertet. Das Korpus umfasst Stellenanzeigen, die über das Portal Open-BiblioJobs und die DFN-Mailingliste Forschungsdaten beworben wurden und deckt einen Zeitraum vom 01.03.2020 bis zum 22.11.2020 ab. Zur Auswertung des Korpus wurde eine Analysematrix erstellt, in welcher die Inhalte jeder Stellenanzeige nach formalen, administrativen und inhaltlichen Kriterien verzeichnet wurden. Die aus den Stellenanzeigen stammenden Anforderungen wurden in einem Forschungsdatenlebenszyklus mit insgesamt acht Teilaspekten verortet, hiervon sechs Stationen des Forschungsdatenlebenszyklus: „Forschungsvorhaben planen“, „Daten erheben“, „Daten aufbereiten und analysieren“, „Daten teilen und publizieren“, „Daten archivieren“, „Daten nachnutzen“, zusätzlich wurden die zwei Teilaspekte „allgemeine Kern- und Schlüsselkompetenzen“ und „übergreifende Querschnittsthemen“ hinzugefügt.
Dieser Praxisrepräsentation wurde eine Literaturanalyse gegenübergestellt, welche sich mit Anforderungen und Kompetenzen im Forschungsdatenmanagement, besonders aus informationswissenschaftlicher, infrastruktureller Sicht beschäftigt. Hierbei wurden exemplarisch Frameworks (international, national, institutionell), Praxisberichte (universitärer und außeruniversitärer Einrichtungen) und der Individualbericht eines Forschungsdatenmanagers ausgewertet. Zur Gewährleistung einer späteren Vergleichbarkeit wurden auch hier die genannten Kompetenzen und Aufgaben in einem gleichen Forschungsdatenlebenszyklus verortet und analysiert. Die abschließende Zusammenführung und Auswertung der um Aufgaben und Kompetenzen angereicherten Forschungsdatenlebenszyklen ermöglichte einen direkten Vergleich von Theorie und Praxis. Hierbei konnte eine große Kongruenz der Schwerpunktverteilung innerhalb des Forschungsdatenlebenszyklus aufgezeigt werden. Diese Aufgabenkonzentration, besonders in den Teilaspekten „allgemeine Kern- und Schlüsselkompetenzen“ und „übergreifende Querschnittsthemen“ bilden die Verteilung von Arbeitsschwerpunkten im Forschungsdatenmanagement für Informationswissenschaftler* innen deutlich ab.
In the context of the Fostering Women to STEM MOOCs (FOSTWOM) project, we present here the general ideas of a gender balance Toolkit, i.e. a collection of recommendations and resources for instructional designers, visual designers, and teaching staff to apply while designing and preparing storyboards for MOOCs and their visual components, so that future STEM online courses have a greater chance to be more inclusive and gender-balanced. Overall, The FOSTWOM project intends to use the inclusive potential of Massive Open Online Courses to propose STEM subjects free of stereotyping assumptions on gender abilities. Moreover, the consortium is interested in attracting girls and young women to science and technology careers, through accessible online content, which can include role models’ interviews, relevant real-world situations, and strong conceptual frameworks.
In an attempt to pave the way for more extensive Computer Science Education (CSE) coverage in K-12, this research developed and made a preliminary evaluation of a blended-learning Introduction to CS program based on an academic MOOC. Using an academic MOOC that is pedagogically effective and engaging, such a program may provide teachers with disciplinary scaffolds and allow them to focus their attention on enhancing students’ learning experience and nurturing critical 21st-century skills such as self-regulated learning. As we demonstrate, this enabled us to introduce an academic level course to middle-school students. In this research, we developed the principals and initial version of such a program, targeting ninth-graders in science-track classes who learn CS as part of their standard curriculum. We found that the middle-schoolers who participated in the program achieved academic results on par with undergraduate students taking this MOOC for academic credit. Participating students also developed a more accurate perception of the essence of CS as a scientific discipline. The unplanned school closure due to the COVID19 pandemic outbreak challenged the research but underlined the advantages of such a MOOCbased blended learning program above classic pedagogy in times of global or local crises that lead to school closure. While most of the science track classes seem to stop learning CS almost entirely, and the end-of-year MoE exam was discarded, the program’s classes smoothly moved to remote learning mode, and students continued to study at a pace similar to that experienced before the school shut down.
The MITx MicroMasters Program in Supply Chain Management (SCM) is a Massive Open Online Course (MOOC) based program that aims to impart quantitative and qualitative knowledge to SCM enthusiasts all around the world. The program that started in 2014 with just one course, now offers 5 courses and one final proctored exam, which allows a learner to gain a MicroMasters credential upon completion. While the courses are delivered in the form of pre-recorded videos by the faculty members of Massachusetts Institute of Technology (MIT), the questions and comments posted by learners in discussion forums are addressed by a group of Community Teaching Assistants (CTAs) who volunteer for this role. The MITx staff carefully selects CTAs for each run of the individual courses as they take on a co-facilitator’s role in the program. This paper highlights the importance of community teaching, discusses the profile of CTAs involved with the program, their recruitment, training, tasks and responsibilities, engagement, and rewarding process. In the end we also share a few recommendations based on the lessons learned in community teaching during the last five years of running more than 45 MOOC courses, that could help other MOOC teams deliver a high-touch experience.
TransPipe
(2021)
Online learning environments, such as Massive Open Online Courses (MOOCs), often rely on videos as a major component to convey knowledge. However, these videos exclude potential participants who do not understand the lecturer’s language, regardless of whether that is due to language unfamiliarity or aural handicaps. Subtitles and/or interactive transcripts solve this issue, ease navigation based on the content, and enable indexing and retrieval by search engines. Although there are several automated speech-to-text converters and translation tools, their quality varies and the process of integrating them can be quite tedious. Thus, in practice, many videos on MOOC platforms only receive subtitles after the course is already finished (if at all) due to a lack of resources. This work describes an approach to tackle this issue by providing a dedicated tool, which is closing this gap between MOOC platforms and transcription and translation tools and offering a simple workflow that can easily be handled by users with a less technical background. The proposed method is designed and evaluated by qualitative interviews with three major MOOC providers.
In this paper, we take a closer look at the development of Massive Open Online Courses (MOOC) in Norway. We want to contribute to nuancing the image of a sound and sustainable policy for flexible and lifelong learning at national and institutional levels and point to some critical areas of improvement in higher education institutions (HEI). 10 semistructured qualitative interviews were carried out in the autumn 2020 at ten different HE institutions across Norway. The informants were strategically selected among employees involved in MOOC-technology, MOOCproduction and MOOC-support over a period of time stretching from 2010–2020. A main finding is that academics engaged in MOOCs find that their entrepreneurial ideas and results, to a large extent, are overlooked at higher institutional levels, and that progress is frustratingly slow. So far, there seems to be little common understanding of the MOOC-concept and the disruptive and transformative effect that MOOC-technology may have at HEIs. At national levels, digital strategies, funding and digital infrastructure are mainly provided in governmental silos. We suggest that governmental bodies and institutional stake holders pay more attention to entrepreneurial MOOC-initiatives to develop sustainability in flexible and lifelong learning in HEIs. This involves connecting the generous funding of digital projects to the provision of a national portal and platform for Open Access to education. To facilitate sustainable lifelong learning in and across HEIs, more quality control to enhance the legitimacy of MOOC certificates and micro-credentials is also a necessary measure.
Developing highly skilled researchers is essential to accelerate the economic progress of developing countries such as Cambodia in South East Asia. While there is continuing research investigating Cambodia’s potential to cultivate such a workforce, the circumstances of undergraduate students in public provincial universities do not receive ample attention. This is crucial as numerous multinational corporations are participating via foreign direct investments in special economic zones at the border provinces and need talented human resources in Cambodia as well as in neighboring Southeast Asian countries such as Thailand and Vietnam. Student’s research capability growth starts with one’s belief in their capacity to use the necessary information tools and their potential to succeed in research. In this research paper, we look at how such beliefs, specifically research self-efficacy and information literacy, can be developed through a short-term intervention that uses MOOCs and assess their long-term effects. Our previous research has shown that short-term training intervention has immediate positive effects on the undergraduate students’ self-efficacies in Cambodian public provincial universities. In this paper, we present the follow-up study results conducted sixteen months after the said short-term training intervention. Results reveal that from follow-up evaluations that while student’s self-efficacies were significantly higher than before the short-term intervention was completed, they were lower than immediately after the intervention. Thus, while perfunctory interventions such as merely introducing the students to MOOCs and other relevant research tools over as little as three weeks can have significant positive effects, efforts must be made to sustain the benefits gained. This implication is essential to developing countries such as Cambodia that need low-cost solutions with immediate positive results in developing human resources to conduct research, particularly in areas far from more developed capital cities.
If taking a flipped learning approach, MOOC content can be used for online pre-class instruction. After which students can put the knowledge they gained from the MOOC into practice either synchronously or asynchronously. This study examined one such, asynchronous, course in teacher education. The course ran with 40 students over 13 weeks from February to May 2020. A case study approach was followed using mixed methods to assess the efficacy of the course. Quantitative data was gathered on achievement of learning outcomes, online engagement, and satisfaction. Qualitative data was gathered via student interviews from which a thematic analysis was undertaken. From a combined analysis of the data, three themes emerged as pertinent to course efficacy: quality and quantity of communication and collaboration; suitability of the MOOC; and significance for career development.
The COVID-19 pandemic has accelerated the pace of digital transformation, which has forced people to quickly adapt to working and collaborating online. Learning in digital environments has without a doubt gained increased significance during this rather unique time and, therefore, Massive Open Online Courses (MOOCs) have more potential to attract a wider target audience. This has also brought about more possibilities for global collaboration among learners as learning is not limited to physical spaces. Despite the wide interest in MOOCs, there is a need for further research on the global collaboration potential they offer. The aim of this paper is to adopt an action research approach to study how a hybrid MOOC design enables learners’ global collaboration. During the years 2019–2020 together with an international consortium called Corship (Corporate Edupreneurship) we jointly designed, created and implemented a hybrid model MOOC, called the “Co-innovation Journey for Startups and Corporates”. It was targeted towards startup entrepreneurs, corporate representatives and higher education students and it was funded by the EU. The MOOC started with 2,438 enrolled learners and the completion rate for the first four weeks was 29.7%. Out of these 208 learners enrolled for the last two weeks, which in turn had a completion rate of 58%. These figures were clearly above the general average for MOOCs. According to our findings, we argue that a hybrid MOOC design may foster global collaboration within a learning community even beyond the course boundaries. The course included four weeks of independent learning, an xMOOC part, and two weeks of collaborative learning, a cMOOC part. The xMOOC part supported learners in creating a shared knowledge base, which enhanced the collaborative learning when entering the cMOOC part of the course.
The goal of this paper is to study the demand factors driving enrollment in massive open online courses. Using course level data from a French MOOC platform, we study the course, teacher and institution related characteristics that influence the enrollment decision of students, in a setting where enrollment is open to all students without administrative barriers. Coverage from social and traditional media done around the course is a key driver. In addition, the language of instruction and the (estimated) amount of work needed to complete the course also have a significant impact. The data also suggests that the presence of same-side externalities is limited. Finally, preferences of national and of international students tend to differ on several dimensions.
This paper examines the attempts of implement-ing components of the concept called Civiliza-tional Hexagon as a pathway to civilizing conflict in the Sub-Saharan Africa in the post-Cold War period. Despite significant decline in the violent conflict and substantial progress socio-economic aspects in the period, most states in the region have been facing challenges in their way to civilize conflict related to absence of inclusive political system, weak state unable to monopolize the use of violence in its territory, and social injustice. On the other hand, states like Botswana and Mauritius managed to civilize conflict through significant improvement in democratic consolidation. Besides their relative success in implementing six elements, these states enabled to integrate traditional institutions with modern state apparatus that helped them to fill the gap created as result of exogenous state formation process and the resulting unfinished nation-building project. Additionally, traditional institutions contributed to managing diversity.
Crochet is a popular handcraft all over the world. While other techniques such as knitting or weaving have received technical support over the years through machines, crochet is still a purely manual craft. Not just the act of crochet itself is manual but also the process of creating instructions for new crochet patterns, which is barely supported by domain specific digital solutions. This leads to unstructured and often also ambiguous and erroneous pattern instructions. In this report, we propose a concept to digitally represent crochet patterns. This format incorporates crochet techniques which allows domain specific support for crochet pattern designers during the pattern creation and instruction writing process. As contributions, we present a thorough domain analysis, the concept of a graph structure used as domain specific language to specify crochet patterns and a prototype of a projectional editor using the graph as representation format of patterns and a diagramming system to visualize them in 2D and 3D. By analyzing the domain, we learned about crochet techniques and pain points of designers in their pattern creation workflow. These insights are the basis on which we defined the pattern representation. In order to evaluate our concept, we built a prototype by which the feasibility of the concept is shown and we tested the software with professional crochet designers who approved of the concept.
Information technology and digital solutions as enablers in the tourism sector require continuous development of skills, as digital transformation is characterized by fast change, complexity and uncertainty. This research investigates how a cMOOC concept could support the tourism industry. A consortium of three universities, a tourism association, and a tourist attraction investigates online learning needs and habits of tourism industry stakeholders in the field of digitalization in a cross-border study in the Baltic Sea region. The multi-national survey (n = 244) reveals a high interest in participating in an online learning community, with two-thirds of respondents seeing opportunities to contributing to such community apart from consuming knowledge. The paper demonstrates preferred ways of learning, motivational and hampering aspects as well as types of possible contributions.
Geochemical processes such as mineral dissolution and precipitation alter the microstructure of rocks, and thereby affect their hydraulic and mechanical behaviour. Quantifying these property changes and considering them in reservoir simulations is essential for a sustainable utilisation of the geological subsurface. Due to the lack of alternatives, analytical methods and empirical relations are currently applied to estimate evolving hydraulic and mechanical rock properties associated with chemical reactions. However, the predictive capabilities of analytical approaches remain limited, since they assume idealised microstructures, and thus are not able to reflect property evolution for dynamic processes. Hence, aim of the present thesis is to improve the prediction of permeability and stiffness changes resulting from pore space alterations of reservoir sandstones.
A detailed representation of rock microstructure, including the morphology and connectivity of pores, is essential to accurately determine physical rock properties. For that purpose, three-dimensional pore-scale models of typical reservoir sandstones, obtained from highly resolved micro-computed tomography (micro-CT), are used to numerically calculate permeability and stiffness. In order to adequately depict characteristic distributions of secondary minerals, the virtual samples are systematically altered and resulting trends among the geometric, hydraulic, and mechanical rock properties are quantified. It is demonstrated that the geochemical reaction regime controls the location of mineral precipitation within the pore space, and thereby crucially affects the permeability evolution. This emphasises the requirement of determining distinctive porosity-permeability relationships
by means of digital pore-scale models. By contrast, a substantial impact of spatial alterations patterns on the stiffness evolution of reservoir sandstones are only observed in case of certain microstructures, such as highly porous granular rocks or sandstones comprising framework-supporting cementations. In order to construct synthetic granular samples a process-based approach is proposed including grain deposition and diagenetic cementation. It is demonstrated that the generated samples reliably represent the microstructural complexity of natural sandstones. Thereby, general limitations of imaging techniques can be overcome and various realisations of granular rocks can be flexibly produced. These can be further altered by virtual experiments, offering a fast and cost-effective way to examine the impact of precipitation, dissolution or fracturing on various petrophysical correlations.
The presented research work provides methodological principles to quantify trends in permeability and stiffness resulting from geochemical processes. The calculated physical property relations are directly linked to pore-scale alterations, and thus have a higher accuracy than commonly applied analytical approaches. This will considerably improve the predictive capabilities of reservoir models, and is further relevant to assess and reduce potential risks, such as productivity or injectivity losses as well as reservoir compaction or fault reactivation. Hence, the proposed method is of paramount importance for a wide range of natural and engineered subsurface applications, including geothermal energy systems, hydrocarbon reservoirs, CO2 and energy storage as well as hydrothermal deposit exploration.
Der Verfasser beschäftigt sich mit der Frage des Glaubensübertritts in einem Asylverfahren. Dabei nimmt er Zeitpunkt, Art und Umstände des Religionswechsels in den Blick. Ferner untersucht er, wie die sogenannte Konversion von den zuständigen Behörden und Gerichten zu behandeln und zu bewerten ist. Einführend gibt er einen Überblick zum völkerrechtlichen Schutz der Religions- und Weltanschauungsfreiheit sowie typischen Gefährdungslagen. Überdies befasst er sich mit den Rechtsgrundlagen des Asyl- und Flüchtlingsschutzrechts und stellt Verbindungen zum Flucht- und Verfolgungsgrund der Religion her.
Schwerpunkt bildet die Untersuchung der Verfahrensstadien, in denen die Konversion relevant wird. Dabei berücksichtigt der Verfasser die nationale und europäische Rechtsprechung. Von besonderer Bedeutung sind die Ausführungen zum Zusammenspiel von staatlichen Ermittlungspflichten und Mitwirkungsgeboten von Asylantragstellenden, wobei den Besonderheiten des grund- und menschenrechtlichen Mehrebenensystems Rechnung getragen wird.
Zentral sind ferner die Ausführungen zum Umgang mit Taufurkunden und sonstigen Bescheinigungen über die religiöse Überzeugung. Besonderes Gewicht liegt auf der verfassungsrechtlichen Stellung der Religionsgemeinschaften und der Frage, ob die Entscheidung einer Religionsgemeinschaft, ein neues Mitglied aufzunehmen, die Behörde im Asylverfahren bindet. Diesem Problem widmet sich der Verfasser unter Heranziehung der relevanten Literaturstimmen und einschlägigen Rechtsprechung.
Der rechtswissenschaftliche Beitrag bietet den beteiligten Akteuren nicht nur eine Einführung in das Themengebiet des Glaubensübertritts im Asylverfahren, sondern gibt den Lesenden auch eine praxistaugliche Handlungsunterstützung rund um die wichtigsten Fragen einer Konversion im Asylverfahren an die Hand. Praktische Bezüge entstehen beispielsweise dadurch, dass wichtige Impulse und Empfehlungen für eine gleichermaßen moderne, rechtsstaatliche und grundrechtsorientierte Verfahrensführung entwickelt werden.
EMOOCs 2021
(2021)
From June 22 to June 24, 2021, Hasso Plattner Institute, Potsdam, hosted the seventh European MOOC Stakeholder Summit (EMOOCs 2021) together with the eighth ACM Learning@Scale Conference.
Due to the COVID-19 situation, the conference was held fully online.
The boost in digital education worldwide as a result of the pandemic was also one of the main topics of this year’s EMOOCs. All institutions of learning have been forced to transform and redesign their educational methods, moving from traditional models to hybrid or completely online models at scale. The learnings, derived from practical experience and research, have been explored in EMOOCs 2021 in six tracks and additional workshops, covering various aspects of this field. In this publication, we present papers from the conference’s Experience Track, the Policy Track, the Business Track, the International Track, and the Workshops.

Im Projekt „Forschungsdatenmanagement in Brandenburg (FDM-BB)“ wurden grundlegende Erkenntnisse bezüglich der Anforderungen und des Status Quo im Bereich Forschungsdatenmanagement (FDM) an den acht brandenburgischen Hochschulen generiert mit dem Ziel, daraus konkrete Handlungs- und Implementierungsempfehlungen für Brandenburg abzuleiten.
Mit Hilfe von spezifischen Umfragen (FactSheets, FDM-Palette) an den Hochschulen und Interviews mit den anderen geförderten FDM-Bundeslandinitiativen konnte eine Priorisierung der nächsten Schritte auf dem Weg hin zu einem institutionellen und nachhaltigen Forschungsdatenmanagement identifiziert werden, die jeweils in den Verantwortungsbereichen der folgenden drei Akteursgruppen liegen: Ministerium für Wirtschaft, Forschung und Kultur in Brandenburg (MWFK), die einzelne Hochschule und für gemeinsame Maßnahmen die kooperative Umsetzung durch (fast) alle Hochschulen.
Zusätzlich wurden Implementierungsempfehlungen erarbeitet, wie der lokale Kompetenzaufbau an den einzelnen Hochschulen in Brandenburg, die kooperative Bereitstellung landesweit relevanter IT-Dienste und Dienstleistungen sowie die Koordinierung FDM-BB.
Ziel ist auch, für Brandenburg gemeinsam eine Forschungsdatenstrategie zu formulieren, die alle brandenburgischen Einrichtungen einbezieht und mit Hilfe von kooperativ verteilten Verantwortlichkeiten dem (noch) sehr dynamischen Thema Forschungsdatenmanagement gerecht werden kann.
