This study focuses on a central question: “What strategies do students’ use and what difficulties do they feel when organising, in note form, written argumentative texts?” while simultaneously exploring constructivism and on-line collaborative pair work (dyads). The objective is to observe the practices and difficulties felt by students at the University of Aveiro when working on written argume...

Supporting real-time jobs on MapReduce systems is particularly challenging due to the heterogeneity of the environment, the load imbalance caused by skewed data blocks, as well as real-time response demands imposed by the applications. In this paper we describe our approach for scheduling real-time, skewed MapReduce jobs in heterogeneous systems. Our approach comprises the following components:...

purpose: this article aims to assess the impact of the work environment of the iranian national library and archive (nli) on creativity of its staff based on their opinion. method: keys standard questionnaire was distributed among all staff who had an academic degree. 183 completed questionnaires were collected and analyzed using spss. findings: results showed that the work environment of nli i...

Heterogeneous online learning environments such as Go-Lab foster student-centered and exploratory STEM education through the promotion of Inquiry Learning. Although the learner is encouraged to create learning objects such as concept maps or hypotheses, the interpretation and reflection on them is complicated by differences in their form of representation. This work presents the ConceptCloud ap...

While CSCW research has mostly been focusing on desktop applications there is a growing interest on ubiquitous and tangible computing. We present ethnographic fieldwork and prototypes to address how tangible computing can support collaboration and learning. The student projects at the Academy of Fine Arts in Vienna is a relevant case to study, for the variety and distributed character of the co...

In this paper we present a specific phonics based approach to supporting early literacy. The application system is cooperative and embedded in a "computer-integrated classroom". It provides an interactive writing environment using a visual palette of letters associated with icons and synthetic speech feedback for the writing results. Ongoing developments enhance the intelligent support modules ...

One of the goals of the “Language Technology for LifeLong Learning” project is the creation of an appropriate methodology to support both formal and informal learning. Services are being developed that are based on the interaction between a formal representation of (domain) knowledge in the form of an ontology created by experts and a social component which complements it, that is tags and soci...

This paper describes our design and implementation of an augmented table interface for small group meetings. The system was designed to be used by multiple users in the ubiquitous environment, where people do not need to bring their laptop PCs. With effective use of the advantage of computer vision, we implemented the concept of ubiquitous desktop as personal workspace and virtual Chinese table...

We present the notion of Active Documents as an approach for providing support for teamwork in ubiquitous computing environments. The main idea is that the document should actively participate in the work, and thereby be able to provide different kind of services. We present an architecture that consists of a Jinibased mobile agent platform and a context information infrastructure where Active ...
