How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

- iTEC - Innovative Technologies for an Engaging Classroom
- With funding of €9.45 million from the European Commission’s FP7 programme, iTEC is the largest and most strategic project yet undertaken by European Schoolnet and has the potential to be a flagship project for the design of the future classroom.
Business information systems (BIS) comprise technological (e.g. programs), informational (e.g. content) and social artifacts (e.g. collaboration structures). Typically, such systems are constantly and collectively developed (co-developed) further by a variety of individuals within the organization. By recognizing these varying types of actors (conc...
In large situated information system instances, a great variety of stakeholders interact with each other via technology, constantly shaping and refining the information system. In the course of such a system's history, a range of domain-specific languages may have been incorporated. These language means are often not sufficiently integrated on an o...
Mashup environments enable end users to directly engage in the design process of the information system. Traditional mashup tech- nology offers users generic components and therefore targets technically skilled people. Recent research investigates domain-specific mashup plat- forms with the aim to be easier to understand and use. We present a pro-...
This article reflects on existing and emerging future challenges arising in the area of “evolutionary business information systems”, a class of systems that demand an evolutionary software development process and which support secondary design of various conceptual layers. We place both existing contributions and future research opportunities in co...
Der vorliegende Artikel reflektiert bestehende und zukünftige Herausforderungen im Bereich „evolutionärer betrieblicher Informationssysteme“, einer Gattung von Systemen, die einen evolutionären Softwareentwicklungsprozess erfordern und die eine „sekundäre Gestaltung (secondary design)“ auf mehreren konzeptionellen Ebenen unterstützen. Wir verorten...
The OpenACS community framework is a mature software toolkit for developing online community platforms. Originally invented at a university, it has prospered due to a high commercial demand and major investments, and subsequently settled as an open source project. In this chapter, the authors extend a previous analysis of the evolution of this soft...
Figure 10 – Evolution of collaboration in Learn@WU, among business and technical stakeholders, respectively. The figure aggregates unipartite graphs that show the collaboration relations (edges) between collaborating stakeholders (vertices) in the Learn@WU system. Size and color of both vertices and edges relate to weighted degree/weight within each graph. Layout algorithms: ForceAtlas2 (business subsystems) and Fruchterman-Reingold (technical subsystems)
Figure 9 – Collective collaboration within Learn@WU, among business and technical stakeholders, respectively. Vertices: 15,180 collaborators in the business subsystems, 12 collaborators in the technical subsystems ∙ Edges: collaboration relationships ∙ Rating: size and color saturation of vertices are related to weighted degree. Edge weights are related to collaboration intensity. ∙ Time frame: 2004–2014 (business subsystems), 2008–2014 (technical subsystems) ∙ Layout algorithm: ForceAtlas2
Figure 7 – Evolution of contributions in the technical subsystems at the application and infrastructure layers. Vertices : software developers – Vertices : artifacts (mostly source code) ∙ Edges: contribution relationship ∙ Rating: size of vertices  is related to their out-degree. Edge weights are related to contributions. ∙ Time frame: 2008–2014 ∙ Layout algorithm: ForceAtlas2

Researching the sharing of learning designs is a well-established domain within the technology-enhanced learning research community. However, until now tools supporting educational modelling languages such as IMS Learning Design have reached a wide adoption in today’s school practice. Following a design science research methodology we report on the...
While many innovations in Technology Enhanced Learning (TEL) have emerged over the last two decades, the uptake of these innovations has not always been very successful, particularly in schools. The transition from proof of concept to integration into learning activities has been recognized as a bottleneck for quite some time. This major problem, w...
