In unserer digitalisierten Welt verlagert sich das Lernen in die Cloud. Vom Unterricht in der Schule und der Tafel zum Tablet, hin zu einem lebenslangen Lernen in der Arbeitswelt und sogar darüber hinaus. Wie erfolgreich und attraktiv dieses zeitgemäße Lernen erfolgt, hängt nicht unwesentlich von den technologischen Möglichkeiten ab, die digitale Lernplattformen rund um MOOCs und Schul-Clouds bieten.
Bei deren Weiterentwicklung sollten statt ökonomischen Messgrößen und KPIs die Lernenden und ihre Lernerfahrungen im Vordergrund stehen.
Hierfür wurde ein Optimierungsframework entwickelt, das für die Entwicklung von Lernplattformen anhand verschiedener qualitativer und quantitative Methoden Verbesserungen identifiziert, priorisiert und deren Beurteilung und Umsetzung steuert.
Datengestützte Entscheidungen sollten auf einer ausreichenden Datenbasis aufbauen. Moderne Web-Anwendungen bestehen aber oft aus mehreren Microservices mit jeweils eigener Datenhaltung. Viele Daten sind daher nicht mehr einfach zugänglich. Daher wird in dieser Arbeit ein Learning Analytics Dienst eingeführt, der diese Daten sammelt und verarbeitet. Darauf aufbauend werden Metriken eingeführt, auf deren Grundlage die erfassten Daten nutzbar werden und die somit zu verschiedenen Zwecken verwendet werden können.
Neben der Visualisierung der Daten in Dashboards werden die Daten für eine automatisierte Qualitätskontrolle herangezogen. So kann festgestellt werden, wenn Tests zu schwierig oder die soziale Interaktion in einem MOOC zu gering ist.
Die vorgestellte Infrastruktur lässt sich aber auch verwenden, um verschiedene A/B/n-Tests durchzuführen. In solchen Tests gibt es mehrere Varianten, die an verschiedene Nutzergruppen in einem kontrollierten Experiment erprobt werden. Dank der vorgestellten Testinfrastruktur, die in der HPI MOOC Plattform eingebaut wurde, kann ermittelt werden, ob sich für diese Gruppen statistisch signifikante Änderungen in der Nutzung feststellen lassen. Dies wurde mit fünf verschiedenen Verbesserungen der HPI MOOC Plattform evaluiert, auf der auch openHPI und openSAP basieren.
Dabei konnte gezeigt werden, dass sich Lernende mit reaktivierenden Mails zurück in den Kurs holen lassen. Es ist primär die Kommunikation der unbearbeiteten Lerninhalte des Nutzers, die eine reaktivierende Wirkung hat.
Auch Übersichtsmails, die die Forenaktivität zusammenfassen, haben einen positiven Effekt erzielt.
Ein gezieltes On-Boarding kann dazu führen, dass die Nutzer die Plattform besser verstehen und hierdurch aktiver sind.
Der vierte Test konnte zeigen, dass die Zuordnung von Forenfragen zu einem bestimmten Zeitpunkt im Video und die grafische Anzeige dieser Informationen zu einer erhöhten Forenaktivität führt.
Auch die experimentelle Erprobung von unterschiedlichen Lernmaterialien, wie sie im fünften Test durchgeführt wurde, ist in MOOCs hilfreich, um eine Verbesserung der Kursmaterialien zu erreichen.
Neben diesen funktionalen Verbesserungen wird untersucht wie MOOC Plattformen und Schul-Clouds einen Nutzen bieten können, wenn Nutzern nur eine schwache oder unzuverlässige Internetanbindung zur Verfügung steht (wie dies in vielen deutschen Schulen der Fall ist). Hier wird gezeigt, dass durch ein geschicktes Vorausladen von Daten die Internetanbindungen entlastet werden können. Teile der Lernanwendungen funktionieren dank dieser Anpassungen, selbst wenn keine Verbindung zum Internet besteht.
Als Letztes wird gezeigt, wie Endgeräte sich in einem lokalen Peer-to-Peer CDN gegenseitig mit Daten versorgen können, ohne dass diese aus dem Internet heruntergeladen werden müssen.
Die Technologie des 3D-Drucks hat sich in den letzten Jahrzehnten rasant entwickelt. Im Industriebereich entstehen immer modernere und spezialisiertere Druckverfahren, im Hobby- und Privatanwenderbereich hingegen werden stetig kostengünstigere und einfacher zu bedienende Geräte zugänglich. Einzig im Bildungsbereich scheint das Themenfeld hingegen erst langsam eine Rolle zu spielen, obwohl sich zahlreiche Bezugspunkte für einen Einsatz in verschiedensten Fächern finden lassen. Insbesondere im Fach Wirtschaft-Arbeit-Technik sind die Schnittstellen zum Rahmenlehrplan Berlin/Brandenburg augenscheinlich, doch es liegen erst vereinzelt konkrete und systematische didaktische Konzepte und Vorschläge zur unterrichtspraktischen Einbettung vor. Die Verfasserin versucht daher in dieser Arbeit die Relevanz des Themas für die technische Bildung deutlich zu machen, eine kurze technische Einführung in das für einen schulischen Einsatz besonders geeignete FDM-Druckverfahren zu geben und daran anknüpfend konkrete Umsetzungsvorschläge aufzuzeigen: einerseits in Form eines allgemeinen Phasenmodells zur Planung von Technikunterricht sowie andererseits in Form eines exemplarischen Unterrichtskonzepts. Am Beispiel eines Schachsets wird verdeutlicht, wie Schülerinnen und Schüler zum Anfertigen der Konstruktionsunterlagen digitale CAD-Programme nutzen und anschließend mit Hilfe eines 3D-Druckers additiv fertigen können.
The integration of MOOCs into the Moroccan Higher Education (MHE) took place in 2013 by developing different partnerships and projects at national and international levels. As elsewhere, the Covid-19 crisis has played an important role in accelerating distance education in MHE. However, based on our experience as both university professors and specialists in educational engineering, the effective execution of the digital transition has not yet been implemented. Thus, in this article, we present a retrospective feedback of MOOCs in Morocco, focusing on the policies taken by the government to better support the digital transition in general and MOOCs in particular. We are therefore seeking to establish an optimal scenario for the promotion of MOOCs, which emphasizes the policies to be considered, and which recalls the importance of conducting a delicate articulation taking into account four levels, namely environmental, institutional, organizational and individual. We conclude with recommendations that are inspired by the Moroccan academic contex that focus on the major role that MOOCs plays for university students and on maintaining lifelong learning.
Thai MOOC academy
(2023)
Thai MOOC Academy is a national digital learning platform that has been serving as a mechanism for promoting lifelong learning in Thailand since 2017. It has recently undergone significant improvements and upgrades, including the implementation of a credit bank system and a learner’s eportfolio system interconnected with the platform. Thai MOOC Academy is introducing a national credit bank system for accreditation and management, which allows for the transfer of expected learning outcomes and educational qualifications between formal education, non-formal education, and informal education. The credit bank system has five distinct features, including issuing forgery-prevented certificates, recording learning results, transferring external credits within the same wallet, accumulating learning results, and creating a QR code for verification purposes. The paper discusses the features and future potential of Thai MOOC Academy, as it is extended towards a sandbox for the national credit bank system in Thailand.
How to reuse inclusive stem Moocs in blended settings to engage young girls to scientific careers
(2023)
The FOSTWOM project (2019–2022), an ERASMUS+ funding, gave METID (Politecnico di Milano) and the MOOC Técnico (Instituto Superior Técnico, University of Lisbon), together with other partners, the opportunity to support the design and creation of gender-inclusive MOOCs. Among other project outputs, we designed a toolkit and a framework that enabled the production of two MOOCs for undergraduate and graduate students in Science, Technology, Engineering and Maths (STEM) and used them as academic content free of gender stereotypes about intellectual ability. In this short paper, the authors aim to 1) briefly share the main outputs of the project; 2) tell the story of how the FOSTWOM approach together with 3) a motivational strategy, the Heroine’s Learning Journey, proved to be effective in the context of rural and marginal areas in Brazil, with young girls as a specific target audience.
In an effort to describe and produce different formats for video instruction, the research community in technology-enhanced learning, and MOOC scholars in particular, have focused on the general style of video production: whether it is a digitally scripted “talk-and-chalk” or a “talking head” version of a learning unit. Since these production styles include various sub-elements, this paper deconstructs the inherited elements of video production in the context of educational live-streams. Using over 700 videos – both from synchronous and asynchronous modalities of large video-based platforms (YouTube and Twitch), 92 features were found in eight categories of video production. These include commonly analyzed features such as the use of green screen and a visible instructor, but also less studied features such as social media connections and changing camera perspective depending on the topic being covered. Overall, the research results enable an analysis of common video production styles and a toolbox for categorizing new formats – independent of their final (a)synchronous use in MOOCs. Keywords: video production, MOOC video styles, live-streaming.
Academia-industry collaborations are beneficial when both sides bring strengths to the partnership and the collaboration outcome is of mutual benefit. These types of collaboration projects are seen as a low-risk learning opportunity for both parties. In this paper, government initiatives that can change the business landscape and academia-industry collaborations that can provide upskilling opportunities to fill emerging business needs are discussed. In light of Japan’s push for next-level modernization, a Japanese software company took a positive stance towards building new capabilities outside what it had been offering its customers. Consequently, an academic research group is laying out infrastructure for learning analytics research. An existing learning analytics dashboard was modularized to allow the research group to focus on natural language processing experiments while the software company explores a development framework suitable for data visualization techniques and artificial intelligence development. The results of this endeavor demonstrate that companies working with academia can creatively explore collaborations outside typical university-supported avenues.
“One video fit for all”
(2023)
Online learning in mathematics has always been challenging, especially for mathematics in STEM education. This paper presents how to make “one fit for all” lecture videos for mathematics in STEM education. In general, we do believe that there is no such thing as “one fit for all” video. The curriculum requires a high level of prior knowledge in mathematics from high school to get a good understanding, and the variation of prior knowledge levels among STEM education students is often high. This creates challenges for both online teaching and on-campus teaching. This article presents experimenting and researching on a video format where students can get a real-time feeling, and which fits their needs regarding their existing prior knowledge. They have the possibility to ask and receive answers during the video without having to feel that they must jump into different sources, which helps to reduce unnecessary distractions. The fundamental video format presented here is that of dynamic branching videos, which has to little degree been researched in education related studies. The reason might be that this field is quite new for higher education, and there is relatively high requirement on the video editing skills from the teachers’ side considering the platforms that are available so far. The videos are implemented for engineering students who take the Linear Algebra course at the Norwegian University of Science and Technology in spring 2023. Feedback from the students gathered via anonymous surveys so far (N = 21) is very positive. With the high suitability for online teaching, this video format might lead the trend of online learning in the future. The design and implementation of dynamic videos in mathematics in higher education was presented for the first time at the EMOOCs conference 2023.
This paper investigates private university students’ language learning activities in MOOC platforms and their attitude toward it. The study explores the development of MOOC use in Chinese private universities, with a focus on two modes: online et blended. We conducted empirical studies with students learning French and Japanese as a second foreign language, using questionnaires (N = 387) and interviews (N = 20) at a private university in Wuhan. Our results revealed that the majority of students used the MOOC platform more than twice a week and focused on the MOOC video, materials and assignments. However, we also found that students showed less interest in online communication (forums). Those who worked in the blended learning mode, especially Japanese learning students, had a more positive attitude toward MOOCs than other students.
The TU Delft Extension School for Continuing Education develops and delivers MOOCs, programs and other online courses for lifelong learners and professionals worldwide focused on Science, Engineering & Design. At the beginning of 2022, we started a project to examine whether creating an online course had any impact on TU Delft campus education. Through a survey, we collected feedback from 68 TU Delft lecturers involved in developing and offering online courses and programs for lifelong learners and professionals. The lecturers reported on the impact of developing an online course on a personal and curricular level. The results showed that the developed online materials, and the acquired skills and experiences from creating online courses, were beneficial for campus education, especially during the transition to remote emergency teaching in the COVID-19 lockdown periods. In this short paper, we will describe the responses in detail and map the benefits and challenges experienced by lecturers when implementing their online course materials and newly acquired educational skills on campus. Finally, we will explore future possibilities to extend the reported, already relevant, impact of MOOCs and of other online courses on campus education.
