Learning physics with a computer algebra system
To become proficient problem-solvers, physics students need to form a coherent and flexible understanding of problem situations with which they are confronted. Still, many students have only a limited representation of the problems on which they are working. Therefore, an instructional approach was devised to promote students' understanding of these problems and to support them in forming associations between problem features and solution methods. The approach was based on using the computer alg

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

Learning opportunities in a kindergarten about the concept of probability
In this paper we describe the students’ 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

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

Collaboration Load
Does collaboration increase or decrease cognitive load during learning? On one hand, collaboration enables some degree of division of labour that may reduce cognitive load. On the other hand since interacting, expressing thoughts, monitoring another’s understanding, grounding, etc., are mechanisms inducing some extraneous cognitive load, they may create cognitive overload and impede learning mechanisms. However this additional load may explain why collaboration sometimes leads to knowledge cons

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

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 students’ 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 organization’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

ToxMystery Lesson Plan 2: Case Book: Catch That Hazard!!!
This lesson plan is a follow-up lesson to the introductory ToxMystery activity lesson. It is a paper-based activity that incorporates the character “Toxie” from the computer game activity into a detectives’ “Case Book”. Students will work with the packet “Catch That Hazard!!!” They will follow the clues provided, and work with the ToxMystery computer game activity to fill in the clues. The chemicals to be investigated are introduced on the cover of the Case Book activity packet.

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-olds’ 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 children’s use of normalising, an activity in which children ‘correct’ the geometrical figures while devel

KMsim: A Meta-Modelling Approach and Environment for Creating Process-Oriented Knowledge Management
This paper presents a new approach to modelling process-oriented knowledge management (KM) and describes a simulation environment (called KMSIM) that embodies the approach. Since the beginning of modelling researchers have been looking for better and novel ways to model systems and to use appropriate software to create simulations. The application of the approach and KMSIM make it possible to create realistic business models (BMs) and simulate the consequences of KM interventions and events. The

Giving teachers a hand(book) to develop ict-enhanced skills
Shared web-based knowledge bases, enriched with the possibilities of discussing about their content and of proposing new one, seem to offer the opportunity to diffuse pedagogical innovation. To this aim, the knowledge base should enable teachers to put their own ideas at colleagues’ disposal; and moreover, to improve their pedagogical knowledge by availing themselves of colleagues’ proposals and suggestions. Thus, personal growth evolves in shared knowledge and vice-versa, facilitating the for

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
