Designing Instructional Examples to Reduce Intrinsic Cognitive Load: Molar versus Modular Presentati
It is usually assumed that successful problem solving in knowledge-rich domains depends on the availability of abstract problem-type schemas whose acquisition can be supported by presenting students with worked examples. Conventionally designed worked examples often focus on information that is related to the main components of problem-type schemas, namely on information related to problem-category membership, structural task features, and category-specific solution procedures. However, studying
“Graphical” Jogthrough: expert based methodology for user interface evaluation, applied in the cas
“Walkthrough” and “Jogthrough” techniques are well known expert based methodologies for the evaluation of user interface design. In this paper we describe the use of “Graphical” Jogthrough method for evaluating the interface design of the Network Simulator, an educational simulation program that enables users to virtually build a computer network, install hardware and software components, make the necessary settings and test the functionality of the network. Graphical Jogthrough is a furth
Gridcole: a tailorable grid service based system that supports scripted collaborative learning
This paper introduces Gridcole, a new system that can be easily tailored by educators in order to support the realization of scripted collaborative learning situations. To do so, educators can provide a script specifying the sequence of activities to be performed by learners as well as the tools and documents required to support them. Gridcole can then search for these tools in a service-oriented grid in order to integrate them so that they are available for users during the realization of the s
Achieving Affective Impact: Visual Emotive Communication in Lifelike Pedagogical Agents
Lifelike animated agents for knowledge-based learning environments can provide timely, customized advice to support learnersâ problem-solving activities. By drawing on a rich repertoire of emotive behaviors to exhibit contextually appropriate facial expressions and emotive gestures, these agents could exploit the visual channel to more effectively communicate with learners. To address these issues, this article proposes the emotive-kinesthetic behavior sequencing framework for dynamically seque
Stagecast Creator™ and Webct™: An integrated use of computer programming and a virtual learning en
This paper reports on an effort to use Stagecast Creator™ as a means for developing modelling skills among undergraduate students taking an introductory course in science that took place in a virtual learning environment (WebCT™). 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 Creator™. Students’ reflective journals and reports of s
A Parallel Grid-based Implementation for Real Time Processing of Event Log Data in Collaborative App
Collaborative applications usually register user interaction in the form of semi-structured plain text event log data. Extracting and structuring this data is a prerequisite for later key processes such as the analysis of interactions, assessment of group activity, or the provision of awareness and feedback. Yet, in real situations of online collaborative activity the processing of log data is usually done offline since structuring event log data is, in general, a computationally costly process
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
E-learning environments in medical education: how pervasive computing can influence the educational
As pervasive computing is integrated incrementally with all facets of everyday life, it is reasonable to expect that its further proliferation may influence educational activities as well. Several such arguments have been thoroughly discussed in literature and several projects have been developed. However, little work has been done to investigate how pervasive computing can influence the medical educational process using e-learning platforms, and the prerequisites for such endeavours. In this pi
An Algebra Subsystem for Diagnosing Students' Input in a Physics Tutoring System
To help a student in an introductory physics course do quantitative homework problems, an intelligent tutoring system must determine information of an algebraic nature. This paper describes a subsystem which resolves such questions for Andes2. The capabilities of the subsystem would be useful for any ITS which deals with problems involving complex systems of equations. This subsystem is capable of 1) solving the systems of equations at the level of introductory physics problems, 2) checking the
StudentsÂ’ Activity in Computer-Supported Collaborative Problem Solving in Mathematics
The purpose of this study was to analyse secondary school studentsÂ’ (N = 16) computer-supported collaborative mathematical problem solving. The problem addressed in the study was: What kinds of metacognitive processes appear during computer-supported collaborative learning in mathematics? Another aim of the study was to consider the applicability of networked learning in mathematics. The network-based learning environment Knowledge Forum (KF) was used to support studentsÂ’ collaborative problem
En quoi les TIC changent-elles les pratiques d'ingénierie pédagogique du professeur d'université?
Depuis quelques années, le terme « in-génierie pédagogique » (instructional enginee-ring) est de plus en plus utilisé en rempla-cement de celui de « design pédagogique » (instructional design). Pourquoi? Rappelons d'abord que le terme « design pédagogique » est apparu au cours des années 1960, lors-que certains chercheurs (surtout améri-cains) ont commencé à mettre au point des méthodes systématiques et systémiques de planiï¬cation et de développement de l'en-seignement. Inï
How to use an Instructional Engineering Method and a Modelling Tool
This chapter discusses how to build IMS learning designs focusing on three aspects, instructional engineering, modeling tools and graphical design techniques. First, we propose that instructional de-signers use a systemic and systematic instructional engineering method to build Units of Learning conforming to the IMS-LD speci-fication. MISA, a mature instructional engineering method will serve as the basis to our design approach. Second, we present a graphical modeling tool, MOT+, and a represe
Reactive Learning Objects for Distributed e-Learning Environments
We present a concept of reactive learning objects that goes away from the hydraulic view of e-learning and gives to students activity a central place. First experimentations suggest that this concept should be enlarged to include distributed computation, distributed storage and Web services.
The Semantic Aspects of e-Learning: Using the Knowledge Life Cycle to Manage Semantics for Grid and
The aim of bringing semantics to learning content and services is to enable large scale collaboration of e-learning activities over the Grid infrastructure.
As machines and software applications will be ubiquitously involved in enabling and facilitating this collaboration, it requires a common understanding of the domain, in particular at the conceptual level, so that both computers and human participants of the e-learning activities understand and are able to communicate among themselves thoug
Towards a Domain Specific Application Development Environment for the ELeGI architecture: the Softwa
The Next Generation Grids (NGG) expert group has pioneered the vision of "Invisible Grid" whereby the complexity of Grid systems and architectures is hidden to both developers and users. In this new vision, the Grid has a different role: it will not more provide a virtual computing environment but it will be the basis of a more complex service oriented, knowledge-based and collaborative environment suitable for the specific domains in which citizen and organizations have to operate.

Experiences with Writing Grid Clients for Mobile devices
This paper describes our attempts to write GRID clients for Mobile Devices, such as a PDA, which have restrictive computational and storage facilities. Our experiences are based on an implementation of a mobile GRID client for Finesse, an existing web-based e-learning system.
At this stage of our work we are not looking to novel applications of mobile learning, but rather are exploring the feasibility of mobile devices as GRID platforms, with novel learning applications as our future aim. We ex
