Clustering Students to help Evaluate Learning
In this paper we show how clustering techniques can be applied to student answers generated from a web-based tutoring tool. In particular we are interested in extracting clusters of students based on the mistakes they made using the tool, with the aim of obtaining pedagogically relevant information and providing this feedback to the teacher. The data we used comes from the Logic-ITA, a web-based tutoring tool to practice formal proofs currently in use in the School of Information Technologies at
Designing to facilitate learning through networked technologies: factors influencing the implementat
Recent advances in computers and telecommunications have allowed networked learning to play a significant role to play across the complete spectrum of higher education teaching. One of the most significant UK government initiatives to date has been the development the Information Environment (IE) originally called as the Distributed National Electronic Resource (DNER), which is aiming to create a managed environment for accessing quality assured information resources on the Internet (IE, 2004).
Teaching Expertise is at The Core of ITS Research
To design efficient, flexible and user-adaptable learning environments, we need to embed a great deal of knowledge into them. This paper emphasises the teacher's knowledge, which encompasses all the expertise of the teacher or of the trainer. Thus it is broader than that which is usually called tutoring knowledge. We start with a description of several facets of teaching expertise and of various implementations that have been described in the ITS literature. Then we describe in more detail some
La evaluación social e individual en la era de la educación a distancia en la globalización
En la globalización tan ampliamente fomentada, especialmente por la educación a distancia, debemos cuestionarnos sobre los valores que vivimos en nuestras culturas locales. La evaluación que instauramos dentro de nuestros cursos puede también convertirse en otro mecanismo de homogenización. Para contrarrestar estas desventajas y poder construir juntos sociedades distintas pero solidarias, propongo un análisis de la evaluación como vehículo ideológico de perpetuación de la distribución
The effect of collaborative knowledge modeling at a distance on performance and on learning
This study examines the effect of co-elaborating a knowledge model in dyads at a distance on performance and on learning. Forty-eight adults participated in the study. Participants were trained to re-represent knowledge taken from a text, using an object-typed knowledge modeling editor software tool. Knowledge modeling is similar to concept mapping, except that the former is based on a typology of knowledge objects and a typology of links, and that the structure of the knowledge representation i

ICT Competences Acquisition using the Concorde e-Learning Platform
This communication presents some of the final results obtained in the frame of the EC funded Leonardo da Vinci pilot project with the title "Acquisition of Complementary Competencies through Open and Distance Education" (CONCORDE) and it complements other dissemination papers. Mainly, we focus here on the acquisition of the competences in the information and communication technologies using an innovative pedagogical model implemented at the level of the web platform. The targeted competences res
Usage Analysis Driven by Models in a Pedagogical Context
In the context of distance learning and teaching, the re-engineering process needs a feedback on the learners' usage of the learning system. The feedback is given by interviews, questionnaires, but in the majority of systems, it is given by log files. We consider that it is important to interpret tracks in order to compare the designer's intentions with the learners' activities during a session. In this paper, we present the usage tracking language – UTL. This language was designed to be gener
Semantic Annotation for Learning Material
This paper aims at providing the specification for semantic annotation tools for e-learning. From the specific requirements of annotating learning material, we categorize and evaluate the existing annotation tools, mainly general purpose ones. We illustrate two research prototypes of annotation tools we developed, and evaluate to what extend the specific requirements of annotating learning material are reached by these research prototypes.
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
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

Population Aging and Economic Growth
Between 2000 and 2050, the share of the population aged 60 and over is projected to increase in every country in the world; the same is true for the 80+ population in all but one country (Mali). Worldwide, the largest absolute increases are yet to come. Although labor force participation rates are projected to decline from 2000 to 2040 in most countries, due mainly to changes in their age distributions, laborforce- to-population ratios will actually increase in most countries. This is because lo
Racial Differences in 30-Day Mortality for Pulmonary Embolism
Objectives. Previous studies reported a higher incidence of in-hospital mortality for Black patients who had pulmonary embolism than for White patients. We used a large statewide database to compare 30-day mortality (defined as death within 30 days from the date of latest hospital admission) for Black and White patients who were hospitalized because of pulmonary embolism. Methods. The study cohort consisted of 15531 discharged patients who had been treated for pulmonary embolism at 186 Pennsylv
