A Neural Approach for Modeling the Inference of Awareness in Computer-Supported Collaboration
Individuals interacting in a computer supported collaborative learning (CSCL) environment produce a variety of information elements during their participation; these information elements usually have a complex structure and semantics, which make it rather difficult to find out the behavioral attitudes and profiles of the users involved. This work provides a model that can be used to discover awareness information lying underneath multi-user interaction. This information is initially captured in

Stagecast CreatorÂ™ and WebctÂ™: An integrated use of computer programming and a virtual learning en
This paper reports on an effort to use Stagecast CreatorÂ™ as a means for developing modelling skills among undergraduate students taking an introductory course in science that took place in a virtual learning environment (WebCTÂ™). An inquiry-based curriculum was implemented, which guided students working in small groups to collect and study moon observations and construct a series of successive models of the moon phases using Stagecast CreatorÂ™. StudentsÂ’ reflective journals and reports of s

Learning opportunities in a kindergarten about the concept of probability
In this paper we describe the studentsÂ’ mathematical learning in a kindergarten during a classroom teaching experiment about the concept of probability. We present and analyze the learning opportunities that were created in the classroom as the children tried to resolve their problems, to reason mathematically and to communicate their thinking to others. The results of the research showed that kindergarten children made considerable progress in their probabilistic thinking,when they accepted th

Meanings for Fraction as Number - Measure by Exploring the Number Line
Construction of meanings for fraction as number-measure is studied during the implementation of exploratory tasks concerning comparison and ordering of fractions as well as operations with fractions. 12-year-old students were working collaboratively in groups of two with software that combines graphical and symbolic notation of fractions represented as points on the number line. Fractions as points and segments, ordering fractions as part of kinesthetic activities and abstracting the scaling of

Flexibility in macro-scripts for computer-supported collaborative learning
In the field of computer-supported collaborative learning (CSCL), scripts are designed to support collaboration among distant learners or co-present learners whose interactions are (at least partially) mediated by a computer. The rationale of scripts is to structure collaborative learning processes in order to trigger group interactions that may be rare in free collaboration. Fixing the degree of coercion is a delicate design choice: too rigid scripts would spoil the richness of collaborative in

Designing integrative scripts
Scripts structure the collaborative learning process by constraining interactions, defining a sequence of activities and specifying individual roles. Scripts aim at increasing the probability that collaboration triggers knowledge generative interactions such as conflict resolution, explanation or mutual regulation. Integrative scripts are not bound to collaboration in small groups but include individual activities and class-wide activities. These pre- and poststructuring activities form the dida

Computerized scripts for enhancing collaborative learning
Free collaboration does not systematically produce learning. One way to enhance the effectiveness of collaborative learning is to structure interactions by engaging students in well-defined scripts. A collaboration script is a set of instructions prescribing how students should form groups, how they should interact and collaborate and how they should solve the problem. In computer-supported collaborative learning (CSCL), the script is reified in the interface of the learning environment. This co

Decentralized Service Deployment for Collaborative Environments
In this paper we present the design of a system which allows service deployment in a small-sized group of computers distributed through the Internet. These groups are formed by users who share a common interest, and voluntarily yield their own resources for the achievement of the collaborative activities of the group. Having enough resources contributed by the members of the group, our system guarantees service availability and the fact that the deployment and execution of the services is carrie

Extending the Scope of Asynchronous Collaboration: a Matter of Being Autonomous and Self-sufficient
Asynchronous collaborative applications and systems have to deal with complexities associated with interaction nature, idiosyncrasy of groups and technical and administrative issues. Inclusion of requirements derived from them is costly (in time, resources and economically). Existing solutions addresses asynchronous collaboration via simplification of requirements and by using centralized models. In this paper we present LaCOLLA, a fully decentralized infrastructure for building collaborative ap

Supporting Effective and Useful Web-based Distance Learning
Learners interacting in a Web-based distance learning environment produce a variety of information elements during their participation; these information elements usually have a complex structure and semantics, which makes it rather difficult to find out the behavioral attitudes and profiles of the users involved. User modelling in on-line distance learning is an important research field focusing on two important aspects: describing and predicting studentsÂ’ actions and intentions as well as ada

Gridifying IBM's Generic Log Adapter to Speed-Up the Processing of Log Data
Problem determination in today's computing environments consumes between 30 and 70% of an organizationÂ’s IT resources and represents from one third to one half of their total cost of ownership. The first step to cutting down costs in this area and to enable autonomic computing systems is to have all parts of the system report status in a common log data format and semantics in order to be able to exploit the status information of the system as a whole. The Generic Log Adapter (GLA) is a generic

Educator's Guide to Hosting a Global Health Conference
This guide uses biology, health, and world study topics to engage students in global health issues and solutions from experiential and multidisciplinary perspectives. The guide offers an outline of how to organize and host a "Global Health Conference," and provides suggestions regarding logistics and instructions as well as resource materials for preparing and organizing a student conference. The Global Health Conference is a school event where students present display boards and two-page essays

Contextualizing Discussions in Distance Learning Systems
In distance learning systems, communication tools are rarely integrated into learning activities, which does not encourage their use. The main goal of our work is to mitigate this lack of integration. Our aim is to bring the discussion activities closer to the learning activities, i.e. to situations to which the discussions must ideally relate to in order to promote learning between students. Thus, we suggest two models of forum which are contextual and based on a structuring of discussions resp

Normalising Geometrical Constructions: A Context for the Generation of Meanings for Ratio and Propor
This paper describes aspects of 13 year-oldsÂ’ activity in mathematics as emerged during the implementation of proportional geometric tasks in the classroom. Pupils were working in pairs using a piece of software specially designed for multiple representation (symbolic and graphical) of the variation in parametric procedures with dynamic manipulation of variable. In this paper we discuss childrenÂ’s use of normalising, an activity in which children Â‘correctÂ’ the geometrical figures while devel

Investigating human computer interaction issues in designing efficient virtual learning environments
Today, when an enormous number of computer-based systems exist, the human activities are being computer mediated. Usually, in designing the interface to those systems, the human-computer interaction is left behind without consideration. In this paper, a literature in human-computer interaction is to be reviewed and the technology aspect of human computer interaction is to be analyzed. Also, general design principles are to be reviewed. According to all these issues, recommendations to designing
