In the traditional software development cycle, requirements gathering is considered the most critical phase. Getting the requirements right first time has become a dogma in software engineering because the correction of erroneous or incomplete requirements in later software development phases becomes overly expensive. For product-service systems (P...

With more and more learning, communication and instructional tools, social collaboration and sharing platforms being used in current learning settings, educators and learners are confronted with a patchwork of partly incompatible software components. This support environment exhibits overlapping functionalities and disparate user interfaces, thus c...
Article
Although many innovations exploiting web technologies have been suggested in distance higher education, very little original research exists investigating the impact of web-based learning environments on distance students’ learning processes and outcomes. To close this gap, four sets of data have been collected in a distance- learning course: behav...

All generations of the Web have given rise to new technologies and services for teaching and learning. Ample research projects have investigated their impact on educational processes and students’ learning outcomes. This is especially true for the comparison of online and face-to-face learning or distance and classroom instruction. There is, howeve...

Fernstudium beschreibt eine Organisation von Bildungsprozessen, bei der Lehrende und Studierende räumlich und zeitlich getrennt sind und vorwiegend asynchron miteinander kommunizieren. Traditionelle Lehrmedien sind gedruckte Studienbriefe. Die rasante Ausbreitung Internet-gestützter Information, Kommuni-kation und Interaktion bot seit Beginn der 90...
Conference Paper
The advent of the world-wide web has challenged traditional distance teaching to supplement custom textbooks, video broadcasting and limited personal interaction with computer-based learning technologies, multimedia systems and compter-mediated interaction between geographically dispersed students and teachers. In this paper, we report on a project...

Chapter
Full-text available
The term “cyber-physical system” (CPS) sounds like a brand-new buzzword as it occurs increasingly as a theme of many conferences, in journal articles and books—like this one. Etymologically the prefix cyber derives from the ancient Greek word κυβέρνησις (kybernesis) and originally means control skills. It evolved into the Latin word guvernare and f...

IT experts expect open distributed processing to become the predominant computing infrastructure in the late nineties. All computer supported work places of large enterprises and organizations will then be networked and will be integrated into cross-regional and cross-sector business and information processes. The size and complexity of such applic...

Computational models of human intelligence almost always take the individual as the fundamental unit of analysis. But is this correct? For instance, if intelligence were primarily a group (or more generally, social network) phenomenon, then we would have to dramatically change how we approach the problem of computational intelligence. To explore th...

The Web service standard represents a prominent conversion of the SOA paradigm increasingly used in practice. The (not so knew) technical aspects in combination with the practices introducded by the WEB, lead new challanges in testing Web services often stated in literature. Introduced in this paper is a not invasive functional testing approach for...

Currently we see a plethora of learning object repositories that address the need to share learning content with peers within and across educational institutions. We also observe a growing interest in standards and tool functionality to model didactic scenarios describing the social, spacial and temporal configuration of learning arrangements. Thes...
Article
In Part 1 of this article we discussed the need for information quality and the systematic management of learning materials and learning arrangements. Digital repositories, often called Learning Object Repositories (LOR), were introduced as a promising answer to this challenge. We also derived technological and pedagogical requirements for LORs fro...

Pedagogically well-designed interactive learning objects (LOs) can help students to better understand complex concepts and processes. Such LOs can stimulate higher-level cognitive skills by involving students in interactive learning activities. The design and implementation of interactive LOs is, however, time-consuming and requires special skills....

Full-text available
Investments in the development of high-quality learning content are often lost and successful applications of pedagogical designs are difficult to find and adapt to other contexts because individuals and groups work in isolation. They also lack effective means to codify and share their assets with peers teaching in the same or a similar subject are...

As we get deeper in the information age, traditional ways of learning and knowledge acquisition are challenged with rapidly changing technologies. The growing entanglement of work and education imposes pressure on individuals and universities. Adult learners are increasingly seeking for pervasive study opportunities. Universities are pushed to prov...
Conference Paper
Full-text available
The existing literature on the impact of technology on learning is sketchy and partly inconclusive. A detailed search of the literature shows that current research is nearly all on the impact of technology on children in schools. There is little or nothing on adult education, on lifelong learning or on distance learning. Goal of the EU project Impa...
