Conference Paper
Full-text available
In universities, diverse tools and software systems exist that each facilitates a di↵erent teaching and learning scenario. A deviating approach is taken by Personal Learning Environments (PLE) that aim to provide a common platform. Considering e-portfolios as an integral part of PLEs, especially portfolio-based learning and assessment have to be su...

Mobile devices and associated applications (apps) are an indispensable part of daily life and provide access to important information anytime and anywhere. However, the availability of university-wide services in the mobile sector is still poor. If they exist they usually result from individual activities of students and teachers. Mobile applicatio...
Article
The use of video lectures in distance learning involves the two major problems of searchability and active user participation. In this paper we promote the implementation and usage of a collaborative educational video annotation functionality to overcome these two challenges. Different use cases and requirements, as well as details of the implement...
Book
Lecture recordings, so called e-lectures, are widely spread across universities. But, concerning those e-lectures, there exist two problems. On the one hand, it is very easy for users just to lean back and not become active. From the perspective of learning theory, this is no desirable state. On the other hand, it is a challenge to find relevant co...

Conference Paper
In current tele-teaching platforms the main challenges for learners are searching and filtering through the content and staying focused on learning with the help of the e-lectures. Video annotation and video indexing features may provide support for learners in this situation. In this paper we will introduce one solution for a lecture video annotat...
Conference Paper
In the last decade e-lecturing has become more and more popular. The amount of lecture video data on the World Wide Web (WWW) is growing rapidly. Therefore, a more efficient method for video retrieval in WWW or within large lecture video archives is urgently needed. This paper presents an approach for automated video indexing and video search in la...
Conference Paper
Full-text available
“Internetworking with TCP/IP” is a Massive Open Online Course, held in German at openHPI end of 2012, that attracted a large audience that has not been in contact with higher education before. The course followed the xMOOC model based on a well-defined sequence of learning content, mainly video lectures and interactive self-tests, and with heavy re...
Conference Paper
Mit dem Format des Massive Open Online Courses (MOOC) hat sich in den letzten Jahren eine intensiv diskutierte neue Variante des E-Learnings heraus- gebildet. In unserem Beitrag stellen wir openHPI vor, eine Plattform für MOOCs im Bereich der Informationstechnologie. Anhand von Kolbs Theorie der Lernstile analysieren wir eine Umfrage unter den Teil...
Chapter
With the latest technological development in the last decade, new opportunities for learning environments and educational systems, such as tele-teaching, arose. Nowadays recording technology includes easy and fast workflows, high definition video recording, multiple sources and diverse output formats. With the amount of tele-teaching content growin...
Conference Paper
Full-text available
Recently a new format of online education has emerged that combines video lectures, interactive quizzes and social learning into an event that aspires to attract a massive number of participants. This format, referred to as Massive Open Online Course (MOOC), has garnered considerable public attention, and has been invested with great hopes (and fea...
Conference Paper
In this paper we would like to tackle the problem of user participation, respectively the lack of it, in e-learning platforms, especially in tele-teaching environments. As the basis we use the idea of a culture of participation to analyse existing systems and suggest enhancements for them. Our aim is to help improve the active engagement and collab...
Conference Paper
Parsing user access log files for retrieving additional information is a well known approach to obtaining additional knowledge of a web site. Most research interests focus on identifying users and tracking user behaviour. In contrast, this paper concentrates on the statistical evaluation of all available log data. Therefore, special items of a web...
Article
Multimedia-based tele-teaching and lecture video portals have become more and more popular in the last few years. The amount of multimedia data available on the WWW (World Wide Web) is rapidly growing. Thus, finding lecture video data on the web or within a lecture video portal has become a significant and challenging task. In this paper, we presen...
Article
Full-text available
A lot of content for tele-teaching portals was produced in the last decade. But metadata to filter and search through the content was not generated adequately. That is why it is a new challenge to find solutions how to filter the large amount of data with a small base of metadata available. To engage the user community to generate metadata is one o...
Conference Paper
Tele-teaching, where recorded lectures are streamed via the internet, was identified as the easiest adoptable method to produce large amounts of e-learning content. Due to the nature of the e-learning material produced, it is lacking searchable data and metadata. Social Web technologies have been identified as one way to overcome this problem, beca...
Article
This paper focuses on the problem of finding similar-ities between complex e-learning objects. For a web portal, which contains a lot of different video objects, different types of meta data for these objects are available. To combine the information of these different data types to a combined similarity measure, a distributed calculation algorithm...
Article
A lot of content for tele-lecturing portals was produced in the last decade. But metadata to filter the content was not generated adequately. It therefore takes a long time for users to filter through all the videos available until they find the learning content they are looking for. That is why it is a new challenge to find solutions how to filter...
Article
Playlists are a concept commonly known from music players. Building on the concept of mix tapes they enable the user to select and group their favorite music and thereby creating new compilations of music. Web video portals have adopted this idea to let users create custom combinations of videos. This paper will focus on the task of adding playlist...
Conference Paper
This paper proposes a usability testing method that alters a given usability testing method to make it less costly and time consuming for the investigator. The usage of user-centred methods is motivated and a combination of two user-centred methods suggested. Furthermore this method is combined with other techniques to additionally detect the state...
Conference Paper
The complexity of web applications becomes a big problem, when applications are growing. Especially if new algorithms should be tested and compared, it is important to be able to separate the newly implemented functions from the core system. It is not enough to use standard frameworks to handle this, but to plan a maintainable structure for the app...
Conference Paper
The goal of this work is to compare different versions of three-dimensional product-presentations with two-dimensional ones. Basically the usability of these technologies will be compared and other user related factors will be integrated into the test as well. These factors were determined via a literature research. In order to achieve a generaliza...
