  • Improving the Elasticity of Services with a P2P Infrastructure

    Han, Weidong; Deters, Ralph (2009)
    Projects: EC | SISTER (205030)
    Web Services (WS) are one of the most popular approaches for building distributed systems due to their widespread acceptance within industry and academia, established and open standards, a wealth of development tools/infrastructures (e.g. Apache Axis [1]), and maybe most importantly the number of successful deployments. A key issue in the deployment of WS is the elasticity of services e.g. their ability to respond to changes in the demand by dynamically adding or removing WS provider nodes. T...

    weSPOT: Inquiry based learning meets learning analytics

    Specht, Marcus; Bedek, Michael; Duval, Erik; Held, Peter; Okada, Alexandra; Stefanov, Krassen; Parodi, Elisabetta; Kikis-Papadakis, K; Strahovnik (2013)
    Projects: EC | WESPOT (318499)
    weSPOT, a project supported by the European Commission, addresses several challenges to building personal knowledge, specifically in the area of science. It focuses on inquiry-based learning, in which the learner takes the role of a self-motivated explorer, and provides support for building these skills. The main problem areas weSPOT tackles are the general lack of inquiry skills in students from ages 12 to 25, the dearth of technological support to bolster students’ curiosity, linking ev...

    Inquiry-based science education in secondary school informatics - challenges and rewards

    Nikolova, Nikolina; Stefanova, Eliza (2013)
    Projects: EC | WESPOT (318499)
    The paper presents an application of the inquiry-based science education (IBSE) approach in the context of informatics, specialized classes, in the process of studying Java language by 11 graders. The experiment under consideration presents classes, performed in parallel in two mathematics high schools in Sofia, Bulgaria, in two consequence years. The levels of IBSE as well as meta-levels of inquiry skills developed by students in process of learning are described. Next, the context of the...

    First Steps in Ontology Development: Knowledge Portal for Software Testers

    Gavrilova, Tatiana; Puuronen, Seppo; Alisova, Maria; Petrashe, Elena (2009)
    Projects: EC | SISTER (205030)
    Nowadays, knowledge portals make an important contribution to enabling organizational knowledge management by providing users interactive and personalized interface which facilitates efficient access to various types of information. However, navigation through mass of information represented on the web is not expedient and effective, as well as the development and maintenance. The emerging ontology-based approach serves as a semantic backbone for knowledge constructing, accessing and represen...
