Knowledge Management: As a Mechanism for Large-Scale Technological and Organizational
Change Managem
Organizational and Technological changes in Israeli universities are taking place without a clear and well-planned model for managing those changes. Universities must adapt to daunting social and educational challenges, in which technology is playing a bigger role than ever before. The model we propose is implementing knowledge management strategies for achieving change management at universities in order to facilitate university's transformation. By doing that, we are establishing a well planne
Efficient object based streaming framework for web-based education
An efficient moving object extraction algorithm suitable for real-time content-based multimedia streaming systems is proposed in this paper. A Motion Vector (MV) based object extraction is used to dynamically detect the objects. To utilize the bandwidth efficiently, the important object can be real time detected, encoded, and transmitted with higher quality and higher frame rate than those of background. In order to meet the real-time requirement, no computationally intensive operation is includ
Capitalisation dÂ’une ressource en or : le dictionnaire
The goal of this paper is to explore extensions to electronic dictionaries. Adding certain functions could considerably extend the range of tasks for which they could provide support. Putting the needed information at the distance of a mouse click would allow for active reading. This would require tight coupling of the dictionary with a text editor: all the information in the dictionary should be accessible via a mouseclick. Dictionaries combined with a flashcard system and an exercise generator
Learning to collaborate: Designing collaboration in a 3-D game environment

Progressive computer-supported modelling as a learner activity: A tool for understanding
Recently, computer modelling has been added as a new topic in final examination programmes for physics and mathematics in the Netherlands. It involves constructing, running, evaluating, and extending simulation models. Currently, we are developing curriculum materials to support this new topic. In the course of our work, we became convinced that computer-supported modelling should be an integrated part of the curriculum from early on. Constructing a model involves identifying components, propert
Embedding email in primary schools: developing a tool for collective reflection
Reflection is an important aspect of learning in groups. In collective moments of reflection, learners can share and compare their ideas with others, and by doing so can reach an articulated and personal understanding of a learning task and domain. In the research presented here, e-mail is examined as a means for reflection in the context of group learning. In two design experiments, an e-mail tool is developed that seeks to (1) support collective reflection, and (2) overcome practical problems
Providing Efficient Event Information Management to CSCL Applications
This work aims to explore the importance of carrying out an efficient management of the event information generated from CSCL applications during the collaborative learning process. The achievement of this task first involves the design of a conceptual model of collaborative learning interaction that captures and distinguishes several high-level collaborative learning processes, which in turns leads to a computational model. To achieve that, we first define the main types of event information ge
Regulative support during inquiry learning with
simulations and modeling
Many factors impact learning; the environment and resources available, the domain, how much prior-knowledge a student has, and how well they make use of their metacognitive skills, all of these factors impact new knowledge creation. The series of studies described in this dissertation focuses on the latter; i.e. the metacognitive skillfulness of students. Known collectively as self-regulation, planning, monitoring, and evaluation, when applied appropriately will enhance learning. Students who m
