State of the art on Interaction and Collaboration Analysis
The document focuses on students-machine or students-students' interactions analysis that could support students & teachers, when students work in stand-alone mode or in collaborative technology based learning environments. The document concerns the State of the art on the interaction analysis dimensions and approaches that are already applied. The appropriateness of these approaches is related to the learning environments features, the user's profile, the learning activities, and the context of

This paper reports on the results of a user evaluation of CAERUS, which is a complete context aware educational resource system for outdoor tourist sites and educational centres. CAERUS consists of a handheld delivery application and a desktop administration application and provides a visual interface to add new maps, define regions of interest, add theme-based multimedia tours, and deliver this information to visitors through Pocket PC devices with GPS capability. Fourteen participants used CAE
Constructing structure in number sequences
This paper reports on a design experiment in the domain of number sequences conducted in the course of the WebLabs project1. In this study, we designed and tested a set of activities in which 13-14 year old students use the ToonTalk programming environment to construct models of sequences and series, and then use the WebReports web-based collaboration system to share these models and their observations about them. We utilise a design pattern (programming method) called "Streams" which enables st

En los últimos tiempos se han producido importantes cambios en el mundo universitario. Crecen las exigencias de la sociedad y se amplía el abanico de perfiles universitarios. En este nuevo marco surge la enseñanza abierta y a distancia (ODL, Open and Distance Learning) para suplir las necesidades de aquellos que tienen dificultades para acceder a la universidad "convencional" o bien para los que la prefieren como opción de estudio. Este artículo describe la situación actual de la ODL en el
Trails of Digital and Non-Digital LOs
This document investigates scenarios where learners navigate (follow trails) through environments containing digital and non-digital learning objects, considers some user requirements of systems designed to support the use of trails and presents a possible classification of different types of trail to form an ontology of trails. Separate sections include investigations of trails in different pedagogical approaches, trails in mobile learning scenarios, trails in computer conferencing and the prov
Analysis of the usage of the Virtuoso system
We present our experiences for recording and analyzing usage of the Learning System Virtuoso at the University of Sofia. The description follows the structure that emerged from the joint work on the Kaleidoscope DPULS Project meetings held on February and April 2005. We also show one possible generalisation and one example pattern for tracking the learning problems described.
Is support really necessary within educational games?
Games can be powerful learning devices because of their interactive and multimedia capabilities, and their abilities to keep students motivated, active, deeply immersed and engaged for sustained periods of time. Yet the extent to which this translates into more effective knowledge and skill acquisition is not clear from the research reported so far. Several researchers have stressed that support tools should be added to game environments to ensure that learning takes place. In this paper we will

Collaborative Ontological Engineering of Instructional Design Knowledge for an ITS Authoring Environ
Intelligence in an ITS authoring system could rely on content-based engineering of instructional design (ID) knowledge, i.e. based on principles such as conceptualization, standardization and theory -awareness. An ontology - based architecture with appropriate ontologies has been proposed for a theoryaware ITS authoring system. Ontological engineering (OE) as a collaborative process jointly conducted by an OE expert and an ID expert is presented as a step on a roadmap towards a theory-aware ITS
Distance training, a key mode to support teachers in the integration of ICT ? Towards collaborative
The integration of ICT into the teaching and learning of school subjects remains still rather weak, even in highschools. Changes in users' practices required by such integration have probably been underestimated: teachers are obliged to question and change their professional practices. It turns out that standard training sessions towards ICT have been found to be unsuited for supporting teachers in overcoming their difficulties with this integration. This document describes a specific distance,
Mastering by the teacher of the instrumental genesis in CAS environments: necessity of instrumental
In this article, we study didactic phenomena identified in integration experiments within our classes, CAS(implemented in calculators). From this study, we show the interest of an instrumental approach to understand the influence of tools on the mathematical approach and on the building of students' knowledge: through a process - instrumental genesis - a calculator becomes a mathematical work tool; this process depends on the tool's constraints and potentialities, on students' knowledge, and on
Knowledge, the keystone of TEL design
This talk outlines the arguments supporting the claim that knowledge is the keystone of the design of Technology enhanced learning (TEL) environments. First, I consider the meaning we could attach to knowledge and knowing, and I introduce the notion of conception. Second, I explore how far the problématique of validation is central in our research. And to conclude, I introduce a characterisation of conceptions, which could help in addressing the problem of TEL design at a theoretical level.
Design of adaptive feedback in a web educational system
This paper presents our interdisciplinary approach for the design of a technology-based learning environment for orthopaedic surgery. We present how we designed a part of this environment. This part is in relation to the web environment. The key idea is to produce an intelligent feedback in relation to the learner's activity. The didactical analysis of teaching and learning in the workplace gives a framework to build the computational representation of knowledge. This analysis is shown within th

An Introduction to the Simple Role of Numbers in Social Science Research
Social science is facing increasing demands for research involving 'quantitative' approaches. Among these are the need, expressed by policy-makers, for practical evidence about what works, and the demand, exemplified by the new ESRC guidelines for research training, that all researchers learn something about techniques of analysis involving numbers. At the same time, however, traditional 'quantitative' approaches are facing a major upheaval caused by growing criticism of null hypothesis signific

Their inclusion of pseudoscientific topics include (a) lecture, discussion, and examinations; (b) demonstrations; (c) laboratory experiments; and (d) student attendance at a conference where controversial research
PBL Especially in the Context of Large Classes
This webpage from McMaster University in Canada describes one approach using small groups for using problem-based learning in teaching large classes. The focus of the authors is on teaching medical students but they also describe use of this approach in teaching civil engineering students, geography, etc. The approach described is likely to be of interest to analytical chemistry faculty teaching large classes of undergraduates as well. Links near the end of the document to pdf files contain u
Middle School Portal: Math and Science Pathways (MSP2)
This is one of the best online resources about fractals, and is meant to support a first course in fractal geometry for students without especially strong mathematical preparation. The site is incredibly deep, providing everything from the most basic definitions and non-technical discussions to involved mathematical formulations. Interactive Java applets, downloadable software for the PC and Macintosh, and laboratory activities are also presented. A particularly interesting section of the site e
This is an experiment showing the application of affinity chromatography to the separation of albumin from horse serum. A brief introduction of affinity chromatography and how it is being used in this specific experiment is given. This appears to be a good experiment to show the advantages of affinity chromatography in separating specific proteins from a complex matrix and would be useful in a biochemistry course or a course that is specifically looking at differing types of chromatography.
