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
An Experimental Study on Peer Selection in a P2P Network over PlanetLab
Peer selection is an important aspect in many P2P applications
requiring efficient assignment and execution of
jobs to peer nodes and search and file transfer, among others.
Due to increasing interest of using P2P systems for distributed
computing, peer selection is taking relevance and
several models have been proposed in the P2P literature.
Yet, there are very few experimental studies for peer selection
in P2P networks deployed in real large scale networks.
In this work we present an experimen
The evolution of research on collaborative learning
For many years, theories of collaborative learning tended to focus on how individuals function in a group. More recently, the focus has shifted so that the group itself has become the unit of analysis. In terms of empirical research, the initial goal was to establish whether and under what circumstances collaborative learning was more effective than learning alone. Researchers controlled several independent variables (size of the group, composition of the group, nature of the task, communication
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

The learner knowledge model can be constructed as a sub graph of the global knowledge domain graph. The paper presents the architecture of student self-evaluation and on-line assessm
ELeGI: The European Learning Grid Infrastructure
The purpose of this paper is to describe the ELeGI Project1. ELeGI has the ambitious goal of developing software technologies for effective human learning and promoting and supporting a learning paradigm shift.
A new paradigm focused on knowledge construction using experimental based and collaborative learning approaches in a contextualised, personalised and ubiquitous way will replace the current information transfer paradigm focused on content and on the key authoritative figure of the teache
Supporting teachers when diagnosing their students in algebra
In this paper we will describe our current work on the Lingot project. We
will focus on the description of a software called « Pépite », the objective of which is
to help teachers diagnose their students' algebra competencies. Then we will show
how different uses of Pepite by teachers lead us to define several types of diagnosis in
order to fit better various users' needs.
User Interfaces for a Virtual Learning Environment: Two Study Cases
A recent powerful idea in the design of Web-based learning environments is the usage of virtual places. The employment of interface metaphors is one of the approaches enabling inexperienced users to feel comfortable in such virtual environments. We have designed a Virtual Environment for Distance Education and Training (VEDET), which provides basic virtual spaces, resources, and services. In this paper we discuss the user interface of two Web-based distance learning courses Business on the Inter
Remote or close control of students’ knowledge in ARCADE
Assessment of students’ knowledge and instructors’ feedback are among the
most important elements of education. This paper describes the Arcade Test System that is
used to check and assess students’ knowledge. The Arcade Test System is a dual-purpose online
testing environment that gives the instructor an opportunity to control the level of knowledge
the students have acquired during taking a particular course delivered by the system. On the
one hand, it gives students a way to check their
Futurelab: The potential of open source approaches for education
Free, Libre, Open Source Software (FLOSS) refers to any software distributed under a licence that allows users to change or share the software source code. Futurelab's interest in this area stems from the belief that FLOSS provides an example of peer-production which is driven by collaborative, social modes of interaction and knowledge exchange. This paper discusses some of the potential ways in which the approaches that characterise FLOSS might be applied in educational contexts.,Research repor
Futurelab: Learning with handheld technologies
This handbook offers a guide and resource for those considering exploring handheld technologies for teaching and learning purposes. Four case reports show how different schools, LAs and individuals have attempted to tap the potential of handheld technology for learning, while a wider survey of handheld learning projects gives a sense of the range of work going on, along with contact information.,Research report
Interdisciplinary approach for the design of a learning environment
This paper presents our interdisciplinary approach for the design of a technology-based learning environment for orthopaedic surgery. We present how the didactical analysis of teaching and learning in workplace gives a framework to build the computational representation of knowledge. This analysis is shown within the context of the apprenticeship of concepts of anatomy and orthopaedic surgery.

Intensive case studies for practice across the foundation stage
This paper will provide an introductory overview of the EPPE methodology and findings and focus upon the particular effects of specific teaching and learning practices in pre-schools.
Where settings view educational and social development as complementary and equal in importance, children make better all round progress. Freely chosen play activities often provided the best opportunities for adults to extend children’s thinking, but it seems that a balance between child-initiated play and the
Light Your Way
When there is a power failure, or when we go outside at night, we grab a flashlight so we can find our way. What happens inside a flashlight that makes the bulb light up? Why do we need a switch to turn on a flashlight? Have you ever noticed that for the flashlight to work you must orient the batteries a certain way as you insert them into the casing? Many people do not know that a flashlight is a simple series circuit. In this hands-on activity, students build this everyday household item and d
Informal learning in the workplace
This paper focuses mainly on theoretical frameworks for understanding and investigating informal learning in the workplace, which have been developed through a series of large and small scale projects. The main conclusions are included but readers are referred to other publications for more detailed accounts of individual projects. Two types of framework are discussed. The first group seek to deconstruct the “key concepts” of informal learning, learning from experience, tacit knowledge, tran
Intensive quantities: why they matter to mathematics education
Ever since Piaget's (1952) classic work on number, a fundamental distinction has been drawn in the mathematics literature between extensive and intensive quantities. Extensive quantities (for example, volume, distance) are based on the logic of part-whole relations. Adding 20 decilitres of orange squash to 60 decilitres produces 80 decilitres of orange squash, since the whole is the sum of the parts. Intensive quantities (for example, density, speed) are based on the logic of co-variation. Addin
