Children use both software that has been explicitly developed for them and software for general users. While they obtain clear benefits from software, such as access to creativity tools and learning resources, children are also exposed to several risks and disadvantages, such as privacy violation, inactivity, or safety risks that can even lead to death. The research and development community is addressing and investigating positive and negative impacts of software for children one by one, but no comprehensive model exists that relates software engineering and children as stakeholders in their own right. Aims: The final objective of this line of research is to propose effective ways in which children can be involved in Software Engineering activities as stakeholders. Specifically, in this paper, we investigate the quality aspects that are of interest for children, as quality is a crucial aspect in the developmen...

A Semantic Data Process Model or Process Architecture is a framework to incorporate generic process models, i.e. de nitions, structures, standards, and relationships of the various process elements so that common technology, methods and measurements can be applied by a n y software project. A projectspeci c software p r ocess model e.g. waterfall, spiral, and iterative enhancement models is a re nement of the generic model to re ect the particular needs of the project. This again can be instantiated to an executable process with subprocesses to develop a particular software. Thus we h a ve the following bindings: underlying semantic model ! generic process model ! project-speci c process model ! concrete processes. A Software P r ocess Management PM environment should enact and control development activities semi-automatically and concurrently. The following six themes seem to us the most interesting for clarify and assess existing PM systems and paradigms:

These studies are often used by researchers as pilot experiments before they are carried out in industrial environments. Reports on these studies usually focus on the results obtained and issues such as their external validity. However, the effects and value of empirical studies with students may go beyond the contribution to scientific literature. For instance, the pedagogical challenges and value of these studies is hardly ever stressed.

This chapter faces the problem of identifying a set of parameters characterizing COTS products. The need for such a characterization derives from the problem to identify and select among many available products the ones which are appropriate for a specific software system. The characterization should allow to foresee the integration and maintenance effort in target systems developed with a COTS-based approach.

We have run a literature review and analyzed papers published in computer science journals and conferences to establish a knowledge base of the multidisciplinary field of software engineering and art with focus on interactive installation art. In addition we have observed several projects of new media art production.

The paper describes how the experiment was integrated in the course, and presents an evaluation of the experiment from an educational point of view.

E3 offers a process modeling language and a supporting system for model construction, change, and inspection. A functioning prototype is available at 12. In this work, Ib look back and I try to reconstruct the research process that led to requirements definition, design, implementation, and validation of the system. The goal of this paper is to give an answer to one main research question.

A series of workshops targeted to primary education students are being performed. In these workshops students enrolled with creative context and geometrical tabletop applications. Through these activities researchers are capturing a wide range of learning analytics data (surveys, observations, performance tests, interviews). These learning analytics provides an increased understanding of the learner behavior when he is enrolled with technology intensive creative activities.

This general model describes activities, tools, products, responsibilities, and metrics issues.

The method is based on object oriented design extended with a kernel of PM specific classes and relations. A graphical notation to depict process model designs is given together with few structuring and presentation rules.

We stress the importance of sharing knowledge through storytelling. Well-designed, well-told stories can help others learn from past situations to respond more effectively in future situation.

This is accomplished by project work in teams of five students of which each member has a background in a distinct discipline. The learning experience of each individual student is based on the collaboration in each team. Thus both the role of the teacher and the student becomes different in the Multidisciplinary project work compared to lectures.

To give effective support for software production processes, the relevant work patterns of a company or project should be explicitly modelled, guided (sometimes enforced), reasoned about–and allowed to change. Process modelling (PM) assumes suitable modelling language (s), methods and tools.

By 2003, more users will be able to connect to the Internet through cell phones than through personal computers. This profusion of connected mobile devices poses the largest opportunity for users to access information on the go. The challenge is harnessing the untapped potential.

In this article, we discuss the software engineering issues that appear in one of the new media art subfields, namely interactive installation art, as reported in the scientific literature. Interactive installations are often built in small multidisciplinary teams, including collaboration between artists and software developers, as the artworks are heavily dependent on software.

Software science and technology communication poses specific challenges as software is by its nature not tangible and not visible.

In an industrial context, the attributes used to select COTS clearly depend on project specific goals. In our educational context we made an attempt to define general COTS characterization attributes. The resulting framework provides a structure, which facilitate the learning process.

The experiment has been run as part of a software process improvement course in which forty students participated. Our hypothesis was that E3 will lead to less problems than IDEF0 when constructing software process models. Here, we show how our experiment has validated the hypothesis.

The experiment has been run as part of a software process improvement course in which forty students participated. Our hypothesis was that E3 will lead to less problems than IDEF0 when constructing software process models. Here, we show how our experiment has validated the hypothesis.
