Analysing the mechanisms of common ground in collaborative web-based interaction
The ideas presented in this paper are challenged especially by the certain critical questions concerning web-based interaction and the qualitative analysis of such interaction and learning. The question arises whether the students from different contexts and countries are able to reach such interaction that would lead them to educationally relevant higher-level discussion and learning in web-based environments. Furthermore, as this field of study is fairly novel, there is a shortage of establish
Giving teachers a hand(book) to develop ict-enhanced skills
Shared web-based knowledge bases, enriched with the possibilities of discussing about their content and of proposing new one, seem to offer the opportunity to diffuse pedagogical innovation. To this aim, the knowledge base should enable teachers to put their own ideas at colleagues disposal; and moreover, to improve their pedagogical knowledge by availing themselves of colleagues proposals and suggestions. Thus, personal growth evolves in shared knowledge and vice-versa, facilitating the for
Scripting argumentation in technology enhanced learning: a proposed system architecture
Argumentative knowledge construction is an important component of critical thinking. Learners who collaboratively argue about a subject can potentially develop domain knowledge and have the opportunity to use evidence critically in order to make sense of the subject under consideration. Moreover learners have to take into account claims and evidence of each other during argumentation and in this way they develop mental models for argument construction and sequence. However, research indicates th

Through Engineering Village 2, an interdisciplinary engineering database, subscribers can now search three engineering databases simultaneously, accessing over 9-million records referencing 5,000 engineering journals and conference materials dating from 1884 and
Training programme for geography teachers
This paper contains a description of a Geography teacher-training program for in-service education. The program is a variant for incorporating the methodology of the Minerva- project Innovative Didactics via Web-based Learning (further abbreviated as IDWBL) so that the Geography teachers at work can be adequately prepared for integrating ICT in geography education at secondary schools via web-based education. The theme may seem at first glance as a variation of a known subject But for the
Jurisdiction in Cyberspace
At its core, jurisdiction is about the boundaries of a sovereign's exercise of its power. What are reasonable constraints on its reach, such that faraway or otherwise unconnected people and institutions can be called to account by the sovereign? Closely related are concepts of choice of law - exactly which sovereign's law to apply to a situation that spans multiple jurisdictions - and venue, which determines the physical location in which the parties are best served to settle their dispute.

BRENDA is a comprehensive database of enzymes maintained by the Institute of Biochemistry at the University of Cologne. Scientists collect and evaluate enzyme function data from primary literature sources. The site has recently been updated with new enzymes and an entirely new search engine. Various searches can be performed, including enzyme name, organism, or EC number. Links to literature citations, two dimensional images, and other databases are included for many of the enzymes.

Narrative Evolution: Learning from Students' Talk about Species Variation
Learners do not always enjoy productive interactions with Multimedia Interactive Learning Environments. Their attention can be distracted away from the educational focus intended by designers and teachers through poor design and operational inadequacy. In this paper we describe a study of groups of learners using a multimedia CD-ROM research tool called Galapagos. This tool was developed to enable us to observe groups of learners interacting with different versions of the same multimedia content

An Intelligent SQL Tutor on the Web
The paper presents SQLT-Web, a Web-enabled intelligent tutoring system for the SQL database language. SQLT-Web is a Web-enabled version of an earlier, standalone ITS. In this paper we describe how the components of the standalone system were reused to develop the Web-enabled system. The system observes students' actions and adapts to their knowledge and learning abilities. We describe the system's architecture in comparison to the architectures of other existing Web-enabled tutors. All tutoring

Lets us look over the shoulders of scientists and glimpse the often-unseen moments of investigation. Take virtual field trips to eight observatories -- Arecibo, where astrobiologists search for signs of life beyond the solar system; Las Cuevas, a research station in Central America's largest remaining rainforest; and others. See interviews, photos, and broadcasts that explore the origins of matter, the universe, and life itself.
We present a concept of reactive learning objects that goes away from the hydraulic view of e-learning and gives to students activity a central place. First experimentations suggest that this concept should be enlarged to include distributed computation, distributed storage and Web services.
In this video segment adapted from NOVA, scientists search for carbonized remains of plants preserved in lava flows to find out how long it has taken rain forests on Hawaii to regenerate after a volcanic eruption.
Within the theoretical framework of Vygotsky's theory, the paper presents a new algebra software. The main features of the software are described and their potentialities are discussed. According to the Vygotskian theory, expressions and commands may be thought as external signs of the Algebraic theory, and as such, they may become instruments of semiotic mediation: In other terms they can be used by the teacher, in the concrete realisation of classroom activity, according to the motive of intr
The aim of this report is simply to help put the design of computer-based systems to support learning on a more scientific footing. The aim is simply stated, but its achievement is more difficult. For one thing, it is not at all obvious what "more scientific" means in this context. However, it is essential for AI-ED research to take better account of the concepts of 'situation', 'context', 'community', 'discourse', 'social learning', and so on, but these terms need to be defined, not used as man
