Martin Varsavsky on How U.S. Tech Firms Differ from Their European Counterparts
Martin Varsavsky's fans see him as a rebel who has often disrupted the telecommunications industry. An Argentine/Spanish entrepreneur who has launched seven companies in the past 20 years, Varsavsky's current venture is FON, which he describes as a "community-empowered company dedicated to building the world's largest global WiFi network." He has a few partners helping him get there -- Skype, eBay and Google. In a podcast interview with Kevin Werbach, a professor of legal studies and ethics at W

The Brave New World of Sovereign Wealth Funds
Sovereign wealth funds, the large investment funds supported by governments, are mostly a positive economic force that can provide a shot in the arm to the companies -- and countries -- they invest in. They are also a stabilizing force for the nation where the investment originates. Those are some of the main takeaways from a new Wharton study, "The Brave New World of Sovereign Wealth Funds." In this interview with Knowledge@Wharton, Wharton management professor Mauro F. Guillén, who helped to

Transforming classroom teaching & learning through technology: Analysis of a case study
The paper discusses the results of a research project based on the field testing of a course aimed at developing arithmetic problem solving skills in primary school pupils. The course was designed to incorporate e-learning techniques, including the use of ARI@ITALES authoring tools. These tools allowed the integration in the course of constructivist activities based on interaction with a set of different microworlds. The aims of the project were twofold: to analyse how the adopted approach and t

Language-independent conceptual "bugs" in novice programming
This article argues for the existence of persistent conceptual "bugs" in how novices program and understand programs. These bugs are not specific to a given programming language, but appear to be language-independent. Furthermore, such bugs occur for novices from primary school to college age. Three different classes of bugs-parallelism, intentionality, and egocentrism - are identified, and exemplified through student errors. It is suggested that these classes of conceptual bugs are rooted in a

Children's mental models of recursive logo programs
Children who had a year of Logo programming experience were asked to think-aloud about what brief Logo recursive programs will do, and then to predict with a hand-simulation of the programs what the Logo graphics turtle will draw when the program is executed. If discrepancies arose in this last phase, children were asked to explain them. A prevaient but misguided "looping" interpretation of Logo recursion was identified, and this robust mental model persisted even in the face of contradiction be

Multimedia and the learner's experience of narrative
This paper reports on research findings which show that the narrative structure of multimedia programs, or sometimes the lack of it, affects learners' comprehension, often adversely [1,2]. It also reports on initial findings from our current research which aims to develop a theoretical understanding of the forms and functions of narrative in interactive media, based on empirical research, and capable of informing instructional design.

Shaping e-Learning Applications for a Service Oriented GriD
The paper discusses technical issues related to establishment of e-learning services on a grid. The XML based technology for implementation of e_learning application in the form of web service is analyzed from the perspective of making an application grid-aware. The special e_learning repository service is proposed as a technique for coordinated use of distributed e_learning resources through the access and invocation of web services.

Collaborative Concept Mapping in Education: Major Research Trends
Since the late eighties, more and more researchers have been exploring the potential of collaborative concept mapping to support learning. In those studies, students construct concept maps in pairs or in small groups. This paper presents a review of research trends on collaborative concept mapping in education. We present an overview of the theoretical framework, methodology and main results of 39 published studies investigating this topic.

Literature Review in Science Education and the Role of ICT: Promise, Problems and Future Directions
Today, what "counts" as science and science teaching is in a state of flux. This, however, is not new - for 150 years there have been debates about the purpose, nature and role of science education in our society. Any designer of resources and tools for the teaching of science therefore needs to be able to understand these debates, and to be aware of the origins and reasons for the changes that are currently taking place.,A NESTA Futurelab Research report - report 6

Literature Review of E-assessment
The authors of this review provide a compelling argument for the central role of assessment in shaping educational practice. They outline the challenges and opportunities posed by the changing global world around us, and the potential role of technologies in our assessment practices. Both optimistic and practical, the review summarises existing research and emergent practice, and provides a blueprint for thinking about the risks and potential that awaits us in this area.,A NESTA Futurelab Resear

Implementation of ICT in Higher Education as Interacting Activity Systems
Implementation of ICT in higher education is not a trivial process. It is however a process leading to a number of challenges and problems. The paper develops a theoretical model of the implementation of ICT in higher education based on activity theory and on a case study in a Danish university. The model suggest that implementation in itself is an activity system. The implementation activity is composed of three processes: Selection of ICT; adaptation of ICT and change of practice with ICT.

Automatically generated exercise pages
In order to generate an exercise page on a particular knowledge, exercises have to be indexed according to the knowledge useful to solve them. Hence, the main idea of this project is to use a problem solver, Argos, to help us deal with this indexation. Argos aims not only at solving geometry problems, but also writes their proofs just as a teacher or a pupil would. Consequently, the meaningful data have to be extracted from the proofs found by the solver. Argos automatically generates rules from

Vers une approche déclarative pour les logiciels de dessins géométriques
Cet article est consacré à la conception d'un environnement d'apprentissage de la géométrie orienté vers la manipulation directe de figures géométriques. À travers deux exemples d'activités, proposées en classe, on distingue les notions de construction géométriques, de spécification, et de manipulation directe. Dans le cadre ainsi défini, nous présentons notre approche. Elle consiste à intégrer des mécanismes et la méthodologie de l'intelligence artificielle dans un logic

Student's modelling with a lattice of conceptions in the domain of linear equations and inequations
We present a student's modelling process in algebra which consists of two phases. The first phase is a local diagnosis where a student's transformation of an expression A into an expression B is diagnosed with a sequence of rewriting rules. A library of correct and incorrect rules has been built for that purpose. The second phase uses a lattice of conceptions built for modelling students more globally. Conceptions are attributed to students according to a mechanism using the local diagnoses as i

Literature Review in Informal Learning with Technology Outside School
When we think about learning, we often tend to think about schools, universities, colleges. If we go a little further and think about learning outside school, we might begin to consider museums, galleries and science centres. What we often tend to overlook, however, is the sort of learning that goes on as part of our normal day-to-day activities when we don't even think we are learning. Today, however, anyone who has an interest in how children learn with digital technologies needs to look beyon

Off-Task Behavior in the Cognitive Tutor Classroom: When Students "Game The System".
We investigate the prevalence and learning impact of different types of off-task behavior in classrooms where students are using intelligent tutoring software. We find that within the classrooms studied, no other type of off-task behavior is associated nearly so strongly with reduced learning as "gaming the system": behavior aimed at obtaining correct answers and advancing within the tutoring curriculum by systematically taking advantage of regularities in the software's feedback and help.
