Evolving from a Traditional Distance Learning Model to e-Learning
This paper presents experiences from the course of Informatics at the Hellenic Open University. Problems faced and lessons learned are presented relating to the introduction of e-learning capabilities into this course that was initially based on a traditional distance-learning model. The paper discusses the need that imposed the introduction of e-learning infrastructure and procedures into the course, the steps taken and the students' attitude towards these changes. It also discusses points whe
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
Resource-adaptive Selection of Strategies in Learning from Worked-Out Examples
Most tasks can be pursued by using different strategies (Logan, 1985; Reder & Schunn, 1998). In this paper we focus on strategies of learning from worked-out examples. Within a resourceoriented framework these different strategies can be classified according to their costs and benefits. These features may determine which strategy will be selected for accomplishing a task in situations with certain resource limitations. We investigate specific hypotheses about strategic adaptations to resource li
Development of Adaptive e-Learning System Based on Learning Objects
This paper discusses Adaptive Educational Hypermedia (AEH), which is at present a hot topic of research and an important aim for e-Learning systems. The presented approach is knowledgebased. The domain ontology and the learning objects play a central role as resources structuring the learning content and supporting flexible adaptive strategies for navigation through this content.
Interoperability framework for Assessment Authoring
Current paper presents a research in the area of e-learning interoperability, and more concrete in assessment area. As first there is reviewed state-of-the-art in specifications, managed by IMS consortium. Next there are discussed relations between these specifications and rationale behind assessment specifications evolution. Next is presented Assessment Interoperability Bus (AIB), as a skeleton for further facilitation of presentation in assessments interoperability. As result there are present
Didactical complexity of computational environments for the learning of mathematics
How a microworld is used by students is crucially influenced by the teacher, who has the responsibility of organising the classroom setting in which learning takes place. For this reason this paper focuses on the teacher as a manager of the learning situation, in relation to the students’ construction of meaning. A model of teaching which takes into account interactions between teacher, students and computer is outlined. Although the focus of this paper will be on the teacher, the teacher w
COW, une plate-forme de support d'exécution de scénarios pédagogiques.
Cet article présente un service de support d'exécution de scénarios pédagogiques conçu pour être intégré dans des plates-formes de formation existantes. Dans un premier temps nous prenons un point de vue ingénierie des plates-formes afin d'identifier les processus de conception et d'utilisation ainsi que les acteurs qui y sont associés. Dans un deuxième temps nous présentons les caractéristiques nécessaires que doit offrir notre service afin que les différents acteurs puissent gé
Collage, a Collaborative Learning Design Editor Based on Patterns Special Issue on Learning Design
This paper introduces Collage, a high-level IMS-LD compliant authoring tool that is specialized for CSCL (Computer-Supported Collaborative Learning). Nowadays CSCL is a key trend in e-learning since it highlights the importance of social interactions as an essential element of learning. CSCL is an interdisciplinary domain, which demands participatory design techniques that allow teachers to get directly involved in design activities. Developing CSCL designs using LD is a difficult task for teach
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.
Framework for integrated learning
In this paper we outline the instructional approach of scripting CSCL. Scripts are didactic scenarios that structure collaborative learning activities in a number of phases. The scripts may define for each phase what task the students have to perform, the composition of the group, the way the task is distributed, the mode of interaction, and the timing of the phase. CSCL scripts can be further differentiated with regard to the design dimensions granularity, degree of coercion, locus of control,
