Using the WWW to Build Learning Communities in K-12 Settings - Part I. Global Network Navigator
The World Wide Web (WWW) can play a vital role in the formation and successful operation of learning communities. Just 18 months ago, there were but 100 WWW servers online worldwide, while today there are over 10,000 WWW servers. Current estimates predict 100,000 WWW servers a year from now, according to M.K. Gray's Measuring the Size and Growth of the Web. This decentralized development of information resources, which cover everything from scientific databases to corporate products to traffic a
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
Cyclone in the classroom: bringing the atmospheric science community into the high school
There has been much discussion about the failure of traditional science education to prepare students for careers in science (Halloun & Hestenes, 1985; Rutherford & Ahlgren, 1990). Students may become adept at solving textbook problems, but they fail to apply the theories that are learned in school to the actual phenomena that the theories attempt to explain (Tinker, 1992). This is in large part due to the fact that students don't often experience phenomena in the classroom. They spend most of t
VCLab as an Example of GRIDifying Virtual Scientific Experiments
This paper describes and summarizes the current state of the development for making the Virtual Control Laboratory (VCLab) a GRID application within the ELeGI project. It introduces shortly into GRID techniques and shows how this GRIDifying process is performed to offer virtual scientific experiments (VSE) on the GRID. The architecture and some technical details of the prototype implementation are presented. The next steps in the development are outlined concerning the collaboration aspects of
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

A study of the development of programming ability and thinking skills in high school students
This article reports on a year-long study of high school students learning computer programming. The study examined three issues: I) what is the impact of programming on particular mathematical and reasoning abilities?; 2) what cognitive skills or abilities best predict programming ability?; and 3) what do students actually understand about programming after two years of high school study? The results showed that even after two years of study, many students had only a rudimentary understanding o
Comprehensive Object-Oriented Learning: The Learner's Perspective
The object-oriented paradigm is increasingly being integrated in computer science education as well as in industry. There is a high demand for understanding the learner’s actions, strategies and thoughts while solving object-oriented problems. Little is known about these processes. Aimed at both teachers and researchers involved in teaching object-oriented technologies, this book reports findings from four case studies, two design experiments and three controlled experiments, with a total of 1
Lessons Learnt from CSCL to Enrich E-Learning
Computer Supported Collaborative learning (CSCL) is nowadays well mature and it is able to set guide-lines to enrich e-learning. On its side, e-learning does not fully exploit its potentialities yet. Suggestions from CSCL could be useful to empower the presence on the e-learning on the market and would foster a vision of learning as not a simple further "commercial product". The European Commission funded many projects involving several countries, numerous students, teachers and researchers, a
Towards On-Line Services Based on a Holistic Analysis of Human Activities
Very often computer scientists view computerization of services in terms of the logistics of human-machine interaction, including establishing a contract, accessing records, and of course designing an interface. But this analysis often moves too quickly to tactical details, failing to frame the entire service in human terms, and not recognizing the mutual learning required to define and relate goals, constraints, and the personalized value of available services. In particular, on-line services t
SCORM and the Learning Grid
The Sharable Content Object Reference Model (SCORM) is a profile of several elearning specification to ensure the reusability and interoperability of elearning content in web based Learning Management Systems (LMSs). Learning grids - learning environments built on the technology of grid services - are a promising new approach to enhance quality of elearning by overcoming the page oriented structure of the web. This paper investigates how SCORM can be used in conjunction with learning grids. Aft
Quality of Service Requirements for the e-Learning Grid
In the same way that the Web has evolved from being a technology designed to aid scientific collaboration to one which is employed extensively in e-business and increasingly in e-learning, the Grid is also evolving from its original concept as a highly distributed dynamic source of computing resources "on tap", like the power grid, for e-science, to a means of supporting enterprise computing across heterogeneous, distributed, virtual organisations. However, even the most recent ideas associated
Analyse de fichiers de traces d'étudiants : aspects didactiques
Users of a learning platforms are usually required to log in, that provides a great deal of data. The general question studied here is: how to exploit this data to help the different actors involved? At first let us introduce the platform and the experiments we conducted. Then we use a didactic model to produce a qualitative analysis from the quantitative data collected. A simple exercise classification emerges from the construction of two indicators. It is consistent with the different experim
