This article aims to outline the methodical proceeding within the project MoKoM funded by the German Research Foundation (DFG) to refine a theoretically derived competency model comprising competencies in the domain of informatics modelling and system comprehension. In this context the first part of this article deals with theoretical aspects of conducting expert interviews and outlines an exemplary analysis of three interview transcripts. It will be illustrated how to empirically refine one of the most important dimensions of the competency model by taking the results of a qualitative content analysis into account. Finally, the illustrated methodical proceeding is reflected and discussed. [ABSTRACT FROM AUTHOR]

Web-services have established their role as facilitating tools for interactive and collaborative learning that supports social knowledge construction. In particular, ePortfolios are gaining importance in supporting the learning process and students΄ reflection. This motivated us to introduce and investigate an interactive mode in an academic course on Human–Computer Interaction (HCI) that adopted ePortfolio or diary-services, interactive spaces for team projects, and personal as well as interpersonal reflection. The qualitative content analysis of the ePortfolio entries illuminates those aspects in the learning process that were unique due to the computer-mediated interaction offerings in the course.
