Initially, in March 2020, when COVID-19 forced conventional face-to-face to pure online teaching, didactic matters were only of secondary importance. At Graz University of Technology (TU Graz, Austria) both the support team for Educational Technology as well as the instructors were mostly concerned with solving technical challenges. Nevertheless, a special tool, the ReDesign Canvas, was available to support lecturers in their endeavor to also address the didactic aspects of their teaching systematically. The article presents the application of the canvas in a redesign of an exemplary lecture.

The technical equipment of first-year students and their preferred communication applications are changing, perhaps also influenced by their experiences in the Covid-19 pandemic concerning digital teaching and learning. This paper presents the 2021 survey of first-year students at Graz University of Technology (N=1,207) and compares the results concerning devices and applications with the results of the surveys conducted since 2011. It is striking that there are no striking changes in the endowment of the that can be interpreted as an effect of Covid-19 pandemic. A question introduced in 2021 about experiences with distance online instruction and experiences with online courses before and after Covid-19 shows clearly that new students' prior experiences with online learning here have dramatically changed as a result of school closures in Austria.

Durch die COVID-19-Pandemie und die damit einhergehende Schließung der Universitäten waren ab dem Sommersemester 2020 aber fast alle Lehrenden der TU Graz gezwungen, ihre Prüfungen in den virtuellen Raum zu verlagern. Dieses Entwicklungspapier soll einerseits den Stand der Forschung wiedergeben, andererseits einen Überblick darüber geben, welche Strategien und Tools an anderen (Technischen) Universitäten international bzw. national eingesetzt werden. Außerdem wird aufgezeigt, welche Arten der Leistungsfeststellung bisher schon an der TU Graz eingesetzt werden und welche Tools dafür in Verwendung sind. Abschließend wird auf zu beachtende Kriterien und mögliche Entwicklungen im Bereich von E-Assessment eingegangen.

Starting from the question of whether the students in the different fields of study differ in terms of several variables related to IT and learning with IT, namely their general extent of IT usage, the extent of IT usage for learning, the IT skills of the students, their participation in online courses, if they learned coding basics at school and the extent of IT usage in class at school, a multiple correspondence analysis (MCA) was chosen to find answers. The MCA resulted in four clusters of fields of study. The inclusion of the variables in the biplot shows that for one dimension the IT skills of the students are crucial, and for the second dimension a further variable, the type of school added as supplementary points, explains the differences between subjects. Finally, the article discusses that these insights might change drastically-especially due to the changed conditions of first-year students with regard to their experiences with the use of IT in learning as a result of the school closures during COVID-19 pandemic. The data for this analysis come from the survey of first-year students at Graz University of Technology (TU Graz) in 2020 (N=955) which is subjected to a secondary analysis in this article.
The technical equipment of first-year students and their preferred communication applications are changing. This paper presents the two latest, unpublished surveys of first-year students at Graz University of Technology (TU Graz) from 2019 (N=824) and 2020 (N=955) and compares the results concerning devices and applications with the results of the surveys conducted since 2011. The analysis shows that laptops, desktop computers and smartphones are among the most important and widespread multifunctional devices, while the MP3 player in particular or the social media application Facebook have lost most of their former importance. The increasing importance of photo-based social media applications, first and foremost Instagram, is striking. If comparing the data from 2019 to those from 2020, the first academic year start that took place within the COVID-19 pandemic, the same applies to the use of Facebook and Facebook Messenger, which now only have the same minor significance as Telegram, Signal, Skype, or others. Concerning effects of the COVID-19 pandemic on the equipment and communication tools used, the authors see a major impact on the prevalence of portable powerpacks.

Almost every child and adult today have access to the Internet and different technologies like smartphones, tablets and co. Scientists recognized this very quickly and started to create a whole new way of learning. Therefore, learning applications have been developed to increase student and adult interest in studying and training. This paper describes the development of a speech-based Alexa Skill for educational purposes. The main goal is to help students as well as adults to learn and train mathematical basic calculation types. The skill was designed in a way that young students as well as adults can interact with Alexa in their own words. Therefore, the skill "Mathe Rätsel" (Eng.: "Math riddle") offers two difficulties to meet the needs of young and old users.
This paper concentrates on the implementation of a new screening method in Austrian schools to assess children and find out if they have any special educational needs in educational areas like phonology, counting, knowledge of letters and numbers and others. The underlying structure of the assignments was developed by developmental psychologists from the University of Graz and the University of Vienna and then implemented as a mobile application for Android tablets. For testing and evaluation purposes, the app's prototype was first used voluntary by multiple Austrian schools. Furthermore, the mobile application had to be fully functional when offline as well as a central web application had to be developed to give the developmental psychologists access to the screening results. However, the main goal was to develop the application in a way that especially children without sufficient skills in reading and writing are able to understand the assignment's tasks and to perform input.

Die Covid-19-Pandemie hat die Schwierigkeiten der Digitalisierung der Lehre von einem Tag auf den anderen zur Priorität und virtuelle Lehre zur zwischenzeitlichen Norm gemacht. Das begleitende Vokabular zur virtuellen Lehre erweist sich dabei als äußerst divers. Dieses Whitepaper schafft eine einheitliche Definition der Kernbegriffe, grenzt diese gegeneinander ab und zeigt die Implikationen für die verschiedenen Stake- holder des Bildungssektors in einer postpandemischen Welt auf. Umsetzungen von virtueller Lehre der unterschiedlichen Hochschultypen, die Ana- lyse der rechtlichen Rahmenbedingungen sowie erste Ansätze für die Mess- und Bewertbarkeit virtueller Lehre geben den Status quo der österreichischen Hoch- schullandschaft wieder. Darauf aufbauend wurden unter Einbezug der Prinzipien zur Qualitätssicherung von virtueller Lehre 10 Empfehlungen als unterstützende Faktoren für die Quanti- fizierung virtueller Lehre an österreichischen Hochschulen erarbeitet: [1] Bereitstellung der notwendigen Infrastruktur und Supportstruktur für virtu- elle Lehre [2] Lehrpersonen mit entsprechenden Angeboten zu (medien-)didaktischen Aus- und Weiterbildungen unterstützen [3] Virtuelle Lehre mit etablierten Verrechnungsschemata quantifizieren [4] Asynchrone Lehraufwände in der Lehrplanung sichtbar machen [5] Gelungene virtuelle Lehre sichtbar machen [6] Virtuelle und hybride Formate fördern [7] Freiheit der Lehre gilt auch für virtuelle Lehre [8] Virtuelle Lehre benötigt rechtliche Grundlagen [9] Virtuelle Lehre benötigt finanzielle Grundlagen [10] Virtuelle Lehre benötigt österreichweite Abstimmung

Over the last years software development life-cycles have continuously been shortened and new releases are being deployed at a more and more frequent level. In order to ensure the quality of those releases, a strong shift towards automated testing at all testing levels has become noticeable throughout the software development industry. At system testing level, the scope of testing is the developed product as a whole, tested in a test environment that has a very close resemblance to the production system. Because of this system-wide scope and the many potential sources for failures, the implementation of automated tests at this level is challenging. Exhaustive testing is neither feasible nor maintainable, therefore proper designed test cases that cover important functionality are essential. Due to increasing laws and regulations on data protection and data privacy, proper management of test data used in automated testing is as important. This paper discusses how automated system tests for TeachCenter 3.0, Graz University of Technology's learning management system, were implemented.

Chatbots have gained enormous popularity in recent years. IT giants such as Microsoft, Google and Facebook have taken an interest in automated conversations. Messaging apps like WhatsApp and Facebook Messenger are playing an increasingly important role in smartphone usage and communication in general perfect conditions for chatbots. This paper provides an introduction of recent chatbot development in general and in customer environments. As part of this work, a chatbot was developed for the Austrian IT company CodeFluegel GmbH. The chatbot, named Theodore, provides information about CodeFluegel via Facebook Messenger and webchat, like the existing company website. The design process and implementation of the chatbot as well as architectural considerations are explained throughout this document. In a user study, participants perform typical tasks with the website and the chatbot. The usage of both platforms is evaluated in order to identify advantages and disadvantages as well as differences compared to the other technology and to draw conclusions. Findings to this study indicate promising prospects for chatbots as alternative touchpoints for customers and others and a way to replace and enhance traditional websites.

Der März 2020 bzw. der mit der COVID19-Krise verbundene Lockdown hat Bildungsinstitutionen insbesondere auch Hochschulen vor große Herausforderungen gestellt. Sprichwörtlich über Nacht wurde ein Schalter umgelegt und die gesamte Lehre musste von vorwiegender oder sogar ausschließlicher Präsenzlehre in eine rein virtuelle transferiert werden. Was bedeutet das aber für eine Universität, wie z. B. die TU Graz die sich grundsätzlich über viele Jahre schon dem Themen E-Learning oder digitale Lehre strategisch verschrieben hat? Solche Fragen wurden mir im März von vielen Seiten gestellt und ich hatte dort alles abgelehnt zu beantworten, weil es schlichtweg nicht ging. Mit etwas Abstand kann man nun aber, hoffentlich nicht zu anekdotisch, Bilanz ziehen.

This research is intended to answer the question, how are the students' perceptions of internet technology in learning and how is the acceptance of Padlet as a microblogging platform for writing skills in German language level A2-B1 CEFR standards for the student. In summary, 21 students within the range of 19-22 years participated, which consisted of 2 males and 19 females - data obtained through opened and closed questionnaires. The results of data analysis showed that students had positive perceptions using internet technology in learning. However, students cannot accept Padlet as a microblogging platform in learning German writing skills due to several factors that influence it. This research has an essential finding: before conducting online learning, lecturers have to consider internet availability and the adequacy of reviews to their smartphones as a learning infrastructure.</p

Simulations and test beds are very difficult topics, especially for non-experienced students or new employees in the mechanical engineering domain. In this chapter, a HoloLens app and a CAD/Simulation workflow are introduced to visualize CAD models and sensor and simulation data of a test run on an air conditioning system test bed. The main challenge is to visualize temperature and pressure changes within opaque parts, such as tubes, compressors, condensers or electrical expansion valves. The HoloLens app supports various simulations and CAD visualizations. We exemplary implemented colouring the temperature or pressure changes of the test bed parts as Mixed-Reality (MR) overlays. The main purpose of the HoloLens app is to reduce the learning effort and time to understand such simulations and test bed settings. Additionally, the app could be used as a communication tool between different departments to transfer experiences and domain specific knowledge.
This article offers an orientation on how research is done in technology-enhanced learning. Therefore, three different approaches to research in the interdisciplinary field will be presented first: hypothesis and theory testing, hypothesis and theory generating, and design oriented methods. Subsequently, some research methods are assigned to the research process - data collection, data analysis, development - and outlined. Finally, hints on the choice of a research method are given and a typical challenge in the field is mentioned.
Gerade in diesen Tagen der COVID-19-Krise erfahren Schüler/-innen und Studierende aber auch Lehrkräfte eine Digitalisierung der Lehre in unvorhersehbarem Ausmaße. Mehr oder weniger über Nacht wurden Bildungseinrichtungen gezwungen die analoge, traditionelle Präsenzlehre einzustellen und auf „digitale Formate“ umzusteigen. Was für die formale Bildung gilt, gilt in diesem Fall auch für die non-formale Bildung sowie für Fort- und Weiterbildungen von Fachkräften der Jugendarbeit. Gelingen kann der digitale Umstieg nur mit einer Herangehensweise, die digitale und analoge Komponenten einbezieht.

The amount of digitalized information increases day by day. Everyone connected to the internet through different devices or interfaces can acquire information of specific topics and interests at every time on every place. Nowadays, nearly every child owns a mobile device or at least has access to a mobile device connected to the internet. The main focus of children is to watch videos or play games on their device, so they always see it as an interesting, entertaining virtual friend. The use of mobile devices containing apps which deliver selected information opens a very interesting channel to deliver knowledge in a hidden way to children. This research deals with the development of an Alexa skill prototype to train 1x1 calculation skills of children in primary school in a very funny and playfully way. To evaluate the speech-assistant technology connected to an education game, a field study in was realized. As the Alexa speech-assistant is anyway absolutely magnetic to children, the feedback of the 1x1 calculation skill was better than expected and motivated us to enhance the base functionalities.

We discuss if and how it is possible to develop meaningful e-assessments in Engineering Mechanics. The focus is on complex example problems, resembling traditional paper-pencil exams. Moreover, the switch to e-assessments should be as transparent as possible for the students, i.e., it shouldn’t lead to additional difficulties, while still maintaining sufficiently high discrimination indices for all questions. Example problems have been designed in such a way, that it is possible to account for a great variety of inputs ranging from graphical to numerical and algebraic as well as string input types. Thanks to the implementation of random variables it is even possible to create an individual set of initial values for every participant. Additionally, when dealing with complex example problems errors carried forward have to be taken into account. Different approaches to do so are detailed and discussed, e.g., pre-defined paths for sub-questions, usage of students’ previous inputs or decision trees. The main finding is that complex example problems in Engineering Mechanics can very well be used in e-assessments if the design of these questions is well structured into meaningful sub-questions and errors carried forward are accounted for.

The COVID-19 crisis influenced universities worldwide in early 2020. In Austria, all universities were closed in March 2020 as a preventive measure, and meetings with over 100 people were banned and a curfew was imposed. This development also had a massive impact on teaching, which in Austria takes place largely face-to-face. In this paper we would like to describe the situation of an Austrian university regarding e-learning before and during the first three weeks of the changeover of the teaching system, using the example of Graz University of Technology (TU Graz). The authors provide insights into the internal procedures, processes and decisions of their university and present figures on the changed usage behaviour of their students and teachers. As a theoretical reference, the article uses the e-learning readiness assessment according to Alshaher (2013), which provides a framework for describing the status of the situation regarding e-learning before the crisis. The paper concludes with a description of enablers, barriers and bottlenecks from the perspective of the members of the Educational Technology department.

Sustainably digitalizing higher education requires a human-centred approach. To address actual problems in teaching as well as learning and increase acceptance, the Technology Enhanced Learning (TEL) solution(s) must be co-designed with affected researchers, teachers, students and administrative staff. We present research-in-progress about a sandpit-informed innovation process with a f2f-marketplace of TEL research and problemmapping as well team formation alongside a competitive call phase, which is followed by a cooperative phase of funded interdisciplinary pilot teams codesigning and implementing TEL innovations. Pilot teams are supported by a University Innovation Canvas to document and reflect on their TEL innovation from multiple viewpoints.

An educational, interactive Amazon Alexa Skill called “Österreich und Europa Spiel / Austria and Europe Game” was developed at Graz University of Technology for a German as well as English speaking audience. This Skills intent is to assist learning geographic facts about Austria as well as Europe by interaction via voice controls with the device. The main research question was if an educational, interactive speech assistant application could be made in a way such that both under-age and full age subjects would be able to use it, enjoy the Game Based Learning experience overall and be assisted learning about the Geography of Austria and Europe. The Amazon Alexa Skill was tested for the first time in a class with 16 students at lower secondary school level. Two further tests were done with a total of five adult participants. After the tests the participants opinion was determined via a questionnaire. The evaluation of the tests suggests that the game indeed gives an additional motivational factor in learning Geography.

Der Denkraum "Neue Medien" hatte zum Ziel sich mit den Auswirkungen von Neuen Medien auf die zukünftige Bildung bzw. die Bildungssysteme zu beschäftigen. Insbesondere sollte dabei der zukünftige heterogene Arbeitsmarkt und die sich ändernden Bedingungen durch eine vielschichtige Gesellschaft im Zentrum der Betrachtungen sein. Es war von an Beginn eigentlich klar, dass die Kombination aus Medien-Arbeit-Bildung durchaus eine Herausforderung werden wird, da es schwer sein wird die Gedanken dazu zu sortieren und zu fokussieren. Aber durch hervorragende Impulsvorträge und einer hochkarätigen Besetzung der Denkraumgruppe wurde zumindest sichergestellt, dass wir unter besten Voraussetzungen arbeiten konnten. Die Gruppe begann zu Beginn mit einem individuellen Brainstorming. Dazu wurde ein Raum von 60 Minuten gegeben, wo wesentliche Eckpunkte und Gedanken zum Verfügung gestellten Positionspapier auf Kärtchen festzuhalten waren. Diese wurden dann in einer zweiten Phase gegenseitig vorgestellt und durch Fragen aus der Gruppe erklärt und vertieft. Wesentlich war, dass jeder genannte Punkte gleichwertig war und wertschätzend behandelt wurde um keine Gedanken von vorhinein zu blockieren. Daraus ergab sich ein bunter Haufen an Karten auf insgesamt zwei Pinnwänden. Einzige Vorgabe war, dass wenn jemand einen bereits vorgestellten Gedanken in seinen eigenen wiederfand, diese Kärtchen zusammenzuhängen (siehe Abb. 1). Der nächste Schritt bestand darin ähnliche Karten zu bündeln und zu kategorisieren mit dem Ziel daraus die Zielfelder unseres Denkraumes zu definieren. Abbildung 1 Übersicht nach dem Brainstorming

Technology Enhanced Learning has become more popular in recent times and many organizations and universities use it as a key instrument in various teaching and training scenarios. At the University of Technology of Graz, some courses require randomized quizzes where question variables can be assigned by arbitrary mathematical functions and this feature is missing in the current solutions. This article describes the development of a quiz application that can be integrated into Moodle by utilization of the Learning Tools Interoperability protocol (LTI). The PHP application is built to support programmable questions that can contain JavaScript and HTML code. Teachers are able to build interactive, randomized quizzes, in which the random variables can be assigned with complex mathematical functions. Furthermore, the application provides a programmable grading mechanism. With this mechanism, it is possible for students to self-assess their performance, as well as for teachers to formally assess their students' learning success automatically and send the results back to Moodle (or other LTI compatible consumer applications).

Massive Open Online Courses, kurz MOOCs, sind einer der Trends im Bereich des tech- nologiegestützten Lehrens und Lernens. Daher ist es wenig verwunderlich, dass alle Bildungssektoren davon profitieren können. Am Beispiel der MOOC-Plattform iMooX. at wird in dem Beitrag die Sichtweise auf diese Form von Online-Kursen dargelegt und gezeigt, auf welch vielfältige Weise diese die Bildung der Gesellschaft erweitern können. Insbesondere ist durch das Aufkommen neuer (medien)didaktischer Formen der Einsatz beträchtlich erweitert worden, sodass MOOCs zukünftig wohl noch eine größere Rolle spielen werden.

Based on the currently developing trend of so called Massive Open Online Courses it is obvious that learning videos are more in use nowadays. This is some kind of comeback because due to the maxim "TV is easy, book is hard" [1][2] videos were used rarely for teaching. A further reason for this rare usage is that it is widely known that a key factor for human learning is a mechanism called selective attention [3][4]. This suggests that managing this attention is from high importance. Such a management could be achieved by providing different forms of interaction and communication in all directions. It has been shown that interaction and communication is crucial for the learning process [6]. Because of these remarks this research study introduces an algorithm which schedules interactions in learning videos and live broadcastings. The algorithm is implemented by a web application and it is based on the concept of a state machine. Finally, the evaluation of the algorithm points out that it is generally working after the improvement of some drawbacks regarding the distribution of interactions in the video.

In this research work, we deal with the topic of the integration of Technology Enhanced Learning in Higher Education. Due to the worldwide debate on digitalization in all possible sectors, educational institutions are asking how they can deal with this change and how they can prepare for the future. At Graz University of Technology, a pre-project was started to define a policy, which should help to encourage the start of new projects with a special focus to education. A participatory approach was utilized with the idea that each university member (lecturers, researchers, administrators or students) could provide input. Different measurements across the fields of education, research, administration, and transformation were carried out, summarized and consolidated to provide a final policy. The outcome of this publication will focus on the description of the whole process as well as the summary of the most interesting aspects, which were used for the final policy. Furthermore, an outlook on how the digital policy will be implemented in the following years will be provided.

There are many reasons for the implementation of authentication on learning platforms. For instance, it is required for the teachers to identify individual students if the learning platform offers some kind of assessment. In addition, authentication is the base for a successful monitoring of the attendance of the students. Compulsory attendance is often applied because many positive effects have been reported by authors of several studies. To monitor the attendance at online videos interactive components can be applied. Another benefit of such interactive components is that they help retain the attention of the students. This study was carried out to examine how the students used a video learning platform which provides interactive components of the videos as part of a course offered at Graz University of Technology. Up until now, a major drawback of this platform has been that the students have been required to register manually on the platform. Now, students are able to use the platform without manual registration and authentication, because these steps happen automatically via the main learning platform that provides all of the course materials. Furthermore, the course design and the application of the interactive components, presenting multiple-choice questions, are evaluated. It is pointed out that the concept improves the performance of the students and equips the teacher with valuable feedback regarding the students' interests.

Although, videos for teaching and learning have been established for many years, transferring of knowledge has changed tremendously within the past decade. Students increasingly consume learning content via videos. In this context, the triumph of YouTube in becoming a main source for learning is astonishing. In combination with an increasing use of online courses, videos however, also need to be focused from a didactical perspective. This fact is one out of a couple of interesting results from 2018's survey amongst first-year students of Graz University of Technology. This survey focuses on the student's IT preferences and competence; it has been executed annually since 2007. Based on more than 9500 datasets, this long-term survey records changes in ownership of students' IT equipment, IT driven communicative behavior, and use of apps as well as social media services over a period of twelve years. One further remarkable result is the very clear rejection of Facebook. Currently, even SMS is more frequently used than Facebook. Thus, it can be stated that Facebook is no longer a major platform for first-year students.

The secondary to tertiary transition is generally considered as problematic. Thereby, especially mathematics is a significant barrier for students of universities. The reasons are diverse and occur not least because of the changes in the school curriculum caused by the centralised school leaving examination. Subsequently, many universities and academies in the European area provide various approaches to work against the widely spread issue. In 2018, a free accessible online bridging courses for mathematics was designed by Graz University of Technology. The course is provided on the iMooX platform 1 and represents a form of technology-enhanced learning. The aim is to optimise the design of the course considering the needs of freshmen and freshwomen. Following the active course period, course participants take part in evaluations. The outcomes are investigated, which represents the empirical part of the paper. The online course receives positive feedback. As a consequence, it is recommended to continue the course offer within the next few years.

Bei Online-Kursen gehören Lernvideos selbstverständlich dazu. Aber auch in Präsenzveranstaltungen wird gerne mit Lernvideos gearbeitet – sie zeigen Dinge, die man sonst nicht im Seminarraum zeigen kann, bringen Dinge präzise auf dem Punkt, dienen auch der Abwechslung. Gerade für Seminare müssen es dabei gar nicht unbedingt Videos sein, die gezielt zum Lernen produziert wurden: Reportagen, Mitschnitte von Gesprächen und Makroaufnahmen können in Präzenzveranstaltungen auch als Übungs- und Anschauungsmaterial eingesetzt werden, wenn z.B. Arbeitsaufträge dazu vergeben werden wie: Welche französischen Redewendungen werden beim Rendezvous im Pariser Straßencafé verwendet? Welche Verbesserungsvorschläge würden Sie dem Tanzpaar geben, das im Video ein paar Runden Wiener Walzer dreht?

In Austria technical education is taught at federal secondary colleges of engineering (HTL) at a quite high level of ISCED 5. Despite mechanical engineering , design with industrial standard 3D programs being state of the art in industry and education, technologies using Internet of Things (IoT) and Augmented Reality (AR) are still at an early stage. This publication describes the introduction of the IoT platform Thingworx at Austrian HTL for mechanical engineering, with focus on AR and IoT from an educational perspective as well as the training aspects from the platform developers' perspective. In addition, an assessment using a system usability scale (SUS) test among students and teachers has been undertaken to obtain knowledge of how students and teachers see the usability of the IoT and AR platform Thingworx. The assessment results are presented in this paper.

Since 2007, Graz University of Technology has been conducting an annual poll amongst its first-year students about their IT preferences and competence. On the basis of more than 8600 data records, this long-term survey reports the changes regarding students´ITstudents´IT device ownership, communicative behavior via IT devices, and use of apps as well as social media services over a time period of eleven years. Furthermore, this publication answers the question, whether the use of emerging technologies in classroom has an influence on these changes or not. It can be stated that an "IT-friendly" environment (most of all internet access) and teaching at secondary school level significantly promotes IT and coding skills but does not intensify the use of social media applications.

Due to the fact that students are confronted with a growing amount of texts, colours, figures and shapes and due to their ability to process only a limited number of such information simultaneously, it seems to be obvious that efforts should be made to increase the students' attention-levels. This is important because research results have indicated that selective attention is considered as the most valuable resource in the process of human learning. The application of interaction and communication to the process of learning is a useful strategy to direct the students' attention. It seems to be obvious that this is also true for learning videos. Therefore, this work contains a description of how a video platform with interactive components can be used to support the students and teacher. The video platform is explained and evaluated by analysing its usage in a large teaching course at an institution of higher education. The application of this strategy improved the students' performance and optimized the teacher's workload.

Blog is simply a shortened version of weblog, a coinage of “web” and “log,” representing an information system that lists diary entries online. Microblogs can be seen as consisting of shorter blog entries. This entry further defines microblogs, then discusses the process of microblogging and how it functions as a means of mass communication.

As active and innovative e-learning researchers, we had been part of the voting crowd but also were applicants to public voting contents on the Web.L3T, a project delivering an open textbook about learning and teaching withtechnologies, was applicant at three public voting contests on the Web: at the‘Neue Deutsche Buchpreis” (2011), at the podcast competition of the MMKH(2011) as well as at the MOOC Production Fellowship (2013). According to our experiences made, we got the impression, that there is a need to re-name ‘publicvoting” to ‘social voting”, as it is not ‘the public” (i.e. the crowd) that decideswho wins. In fact, we found out social aspects, i.e. strong and weak ties in so-cial communities to dictate the voting results. Therefore the publication ad-dresses the research question, whether public voting on the Web is a democratic process at all.
In the last few years, microblogging has become a phenomenon of our daily lives. Communicating, sharing media files, as well as acting on digital social communities platforms using mobile devices assist our everyday activities in a complete new way. Therefore, it is very reasonable that academic environments are influenced arbitrarily too. In this publication, different settings for the use of microblogging are pointed out - for teaching and learning as well as for further scientific purposes such as professional conferences. It can be summarized that there are different possibilities to use microblogging in an academic context; each of them are new advantages for the academic life. The publication gives a short overview and a first insight into the various ways to use microblogging.
In this research work a survey of tested mobile applications will be summarized, which were selected by a few defined prerequisites, and a brief overview is given of what is available in the corresponding stores. It will also be shown how the individual mobile applications for encyclopedias are presenting and providing information to users. This covers its visual representation and the manner in how information is retrieved. Additionally a new smart way will be introduced in which we can deal with information with a special focus to encyclopedias and mobile devices. The prototyped application carries out special features, which makes usage of mobile device capabilities. The presented approach follows a slightly more aggressive way on how to bring information to users. For example it requires the permission of user and tells him/her actively that there is an interesting piece of information close by his/her location. Communication between the device and users is done using the notification system. To satisfy the needs of users a set of options will be presented so that they can customize time and number of notifications. Those settings shall also prevent the battery from draining too fast and give the user control about it. The outcome is a prototype with a set of features which allows users to retrieve information based on their mood and their willingness of spending effort. If he/she is eager to learn, the application provides ways to support that. If he/she just wants some quick information, there are ways to get it. And if he/she wants a new way of information retrieval via mobile applications for encyclopedias, the prototype offers the above-mentioned possibility to do so.

Die Digitalisierung der Hochschule und damit auch oder insbesondere der Hochschullehre ist eines der großen Themen dieser Tage. Durch den digitalen Wandel und die ständig zunehmenden technischen Neuerungen werden viele Prozesse unseres Alltags grundlegendend verändert. Hatten wir noch vor wenigen Jahren einen analogen Kalender mit uns, so gibt es heute eine mobile App. Mussten wir vor der Jahrtausendwende auf das Telefon ausweichen, wenn wir miteinander über große Strecken kommunizieren wollten, so gibt es heute viele mobile Apps die Kommunikation erlauben. Werden heute noch die meisten Glühbirnen mittels Lichtschalter aus- und eingeschaltet, so erlaubt uns das zukünftige Smart Home bereits die Verwendung einer App dafür. Diese Beispiele lassen sich beliebig fortsetzen und je länger man darüber nachdenkt, versteht man, dass wir am Aufbruch in ein komplett neues Zeitalter stehen, welches nur schwer vorherzusagen ist. Jetzt steht aber das Bildungssystem vor enormen Herausforderungen, wenn man bedenkt, dass der Anspruch ist, Schülerinnen und Schüler bzw. Studentinnen und Studenten auf den Berufsalltag vorzubereiten. Vor allem wenn man berücksichtigt, dass ein/e Schulanfänger/in im September 2017, die Primarstufe 2021 abschließt und 2029 zum Abitur antritt. Im besten Falle erfolgt der Bachelorabschluss 2032 und der Master im Jahre 2034. Wenn man nur davon ausgeht, dass die technische Entwicklung der letzten 17 Jahre gleich konservativ voran schreitet, wird es viele neue technische Errungenschaften geben die heute noch nicht bekannt sind. Um die Jahrtausendwende gab es so z.B. noch kein Web 2.0, d.h. die Idee dass die Gesellschaft aktiv am Internet teilnimmt, war damals noch kaum vorstellbar. Facebook, Whatsapp & Co war noch Zukunftsmusik und auch Smartphones (egal ob iPhone oder Androidgeräte) noch gar nicht „erfunden“. Kurzum es ist schwer einen „richtigen“ Weg in die digitale Zukunft der Hochschullehre aufzuzeigen, trotzdem gibt es wohl wichtige Stoßrichtungen um zumindest in die richtige Richtung zu gehen. Dazu werden hier fünf Fragen gestellt und versucht darauf auch Antworten zu geben.

Durch die Erfindung des Computers hat sich das Leben in verschiedenen Bereichen stark verändert: Mobilität und Vernetzung halten Einzug in das tägliche Leben. Um am Puls der Zeit zu bleiben, ist es notwendig auch das bis jetzt nahezu unveränderte Bildungssystem in die Zukunft zu tragen. Ob der zahlreichen politischen Diskussionen konnte man sich bis heute nicht flächendeckend darauf einigen, Informatik als eines der grundlegenden Fächer im Schulbetrieb zu verankern. Ziel der Bildungsinformatik ist es ein Bewusstsein für die notwendigen Kompetenzen der informatischen und medialen Belange der Gesellschaft der Zukunft zu schaffen. Am Beispiel eines Learning-Management-Systems sollen die damit einhergehenden technischen und nicht-technischen Herausforderungen beleuchtet werden um damit auch die Notwendigkeit und Bedeutung der Bildungsinformatik zu verdeutlichen.

Der Beitrag greift das Thema Lern- und Lehrvideos auf und zeigt die aktuellen Einsatzformen auf. Ebenso werden unterschiedliche Formate und Erstellungsmöglichkeiten dargestellt, die durch heutige Technologien teils auch mit überschaubaren finanziellen Ressourcen umgesetzt werden können. Darüber hinaus werden lerntheoretische Ansätze gelistet, die bis heute bekannt sind. Um die Produktion von Lern- und Lehrvideos zukünftig zu erleichtern, wird anhand einer Vorlage zur Entwicklung von Lern- und Lehrvideos, dem Lernvideo-Canvas, gezeigt, wie man an die Planung von Lern- und Lehrvideo-Projekten herangehen kann.

Im Frühling 2017 wurde der EBmooc als erster offener Onlinekurs für Erwachsenenbildner/innen in Österreich erstmals begleitet durchgeführt. Dieser Kurs hatte digitale Tools und Fertigkeiten für die Erwachsenenbildung zum Gegenstand und war mit rund 3000 Teilnehmern/Teilnehmerinnen sehr erfolgreich. Er bildet den Ausgangspunkt der vorliegenden Publikation. Die Reaktionen auf den EBmooc im Feld der Erwachsenenbildung waren im Vorfeld eher abwartend, dann zunehmend begeistert und zustimmend, und nicht nur Unterrichtende, sondern auch Anbietereinrichtungen, Programm- und Produktentwickler/innen zeigten zunehmendes Interesse am Format „MOOC“. Für sie ist dieser Leitfaden gedacht.

Das gemeinsame Schreiben in kurzen Zeiträumen in sogenannten „Booksprints“ hat vor allem durch digitale Technologien an Fahrt gewonnen. Plattformen zur virtuellen Kooperation und Kommunikation sowie schließlich auch zur Online-Veröffentlichung ermöglichen einen gemeinsamen, räumlich verteil- ten und parallelisierten Veröffentlichungsprozess, welcher Absprachen und Übergänge teils drastisch verkürzt. Gerade im Bereich der Hochschulen gibt es jedoch nur wenige Beispiele für Booksprints. In der folgenden vergleichen- den Fallstudie werden drei erfolgreiche Beispiele miteinander verglichen: eine beim E-Learning-Tag in Koblenz in drei Stunden erstellte Textsammlung zu per- sönlichen Erinnerungen an Lieblings-Lernmedien (Auwärter u.a., 2013), die Überarbeitung des Lehrbuchs „Lernen und Lehren mit Technologien“ in sieben Tagen, an dem sich mehr als 250 Mitwirkende beteiligten (L3T 2.0, Ebner & Schön, 2013) sowie ein dreitägiger Booksprint mit der Sammlung von inno- vativen Fallbeispielen zu neuartigen Geschäftsmodellen des Hochschulforums Digitalisierung (Bremer u.a., 2015). Eine Darstellung der Lessons Learned bzw. Empfehlungen für Nachahmer/innen schließt den Beitrag ab.
Die Digitalisierung erfordert die Positionierung der Hochschulen. Sie ver- eint unterschiedliche bzw. separierte Medien-Entwicklungen in Forschung, Lehre und Transfer. Aber: Um welche medien- und bildungstechnologischen Entwicklungen handelt es sich im Einzelnen? Wie steht es um deren Verbreitung an Hochschulen? Wer sind die handelnden Akteure? Der Workshop untersucht diese Fragen in Form eines Stakeholder-Dialogs aus Hochschulen, Dienst- leisterInnen und Netzwerken.

When researchers formulate search queries to find relevant content on the Web, those queries typically consist of keywords that can only be matched in the content or its metadata. The Web of Data extends this functionality by bringing structure and giving well-defined meaning to the content and it enables humans and machines to work together using controlled vocabularies. Due the high degree of mismatches between the structure of the content and the vocabularies in different sources, searching over multiple heterogeneous repositories of structured data is considered challenging. Therefore, the authors present a semantic search engine for researchers facilitating search in research related Linked Data. To facilitate high-precision interactive search, they annotated and interlinked structured research data with ontologies from various repositories in an effective semantic model. Furthermore, the authors' system is adaptive as researchers can synchronize using new social media accounts and efficiently explore new datasets.
Collaboration in general but especially between students of Austrian Federal Secondary Colleges of Engineering (HTL) is becoming more and more important. Therefore, the joint diploma thesis has been introduced into the cur- riculum. Furthermore, joint student projects have become a crucial topic within the subject of mechanical engineering design. Because of the worldwide activi- ties of most companies, being able to collaborate within a huge team is seen as an essential for future jobs. To support the collaboration process in engineering education, a product data management (PDM) system was introduced to several Austrian HTLs within projects carried out in the Sparkling Science program of the Austrian Federal Ministry of Science and Research. In the academic year 2016/17 a field study was started to figure out how to enhance collaboration be- tween students by using this kind of software and methods. The outcome of this study will be to find out about the level of collaboration within students’ design projects.

Viele Jahre war der Einsatz von computergestütztem Lehren und Lernen an (tragbare) Computer gebunden. Ob digitale Hilfsmittel, z. B. Laptop und Video-Projektor, zum Einsatz kamen war deutlich erkennbar. Spätestens mit dem ubiquitären Internet und den Smartphones in den Taschen der Studierenden ist diese Grenzziehung zwischen sog. „analoger“ d. h. herkömmlicher Präsenzlehre sowie dem „digitalen“, d. h. dem computergestützten Lehren und Lernen, vermutlich sogar obsolet. Die Digitalisierung verändert auf unterschiedliche Weise die Lehre. Im Papier wird die These aufgestellt, dass dabei digitale und sogenannte analoge Aspekte immer mehr miteinander verschmelzen. Besonderheiten von verschmolzenen Lern- und Lehrformaten wurden in einem Arbeitspapier, das für das Hochschulforum Digitalisierung erstellt wurde, herausgearbeitet. Im Beitrag werden neun Fallstudien skizziert und ihre Besonderheiten verglichen. Daraus abgeleitet werden Thesen über die Charakteristik von verschmolzenen Lern- und Lehrformaten.
