Integrating the Virtual World: Teaching EAI and e-business Integration at Universities of Applied Sc
In this paper, we report on a technology-enhanced learning approach for teaching integration issues. Virtually available Web services have evolved considerably and teaching enterprise application as well as e-business integration at universities has become commonplace.However, this evolution is limited by the time that is needed for developing learner-centered applications, and most of all, by the resulting costs. By applying a collaborative learning model dans by incorporating shared code, avai
Important Ornaments: The Impact of Graphics and Rule Systems on Academic Wiki Use
Collaborative websites, or wikis, are being used in the classroom to recruit user attention and to disseminate information [1). These wikis place a heavy emphasis on text, while generally neglecting graphics. Little to no research has examined the impact of this textual approach. This paper examines the use of graphics and rule systems as motivating tools in academic wikis. It reports the results of a 6 month long experiment involving 21 10th and 11th grade users to determine the impact of diffe
Changing the Education Culture through Technology
Technology has a potentially rich, but largely unrealised, role in teaching and learning. This role is defined variously by what the teacher has available, has had time to learn, or can find an appropriate use for, and by what students have access to, are familiar with, and are willing to use. In all of these ways, technology usually plays an adjunct role to others, more traditional modalities for teaching and learning, including lecture, laboratory, library, textbook, tutorial, and practicum.

21st September 2006, the most of the internationals media shows the child of Dikika as a discover in Ethiopia : a three age old Australopithecus. The craniums pictures were similar as this we used in a labwork we proposed to pupils in French high school.
Efficient object based streaming framework for web-based education
An efficient moving object extraction algorithm suitable for real-time content-based multimedia streaming systems is proposed in this paper. A Motion Vector (MV) based object extraction is used to dynamically detect the objects. To utilize the bandwidth efficiently, the important object can be real time detected, encoded, and transmitted with higher quality and higher frame rate than those of background. In order to meet the real-time requirement, no computationally intensive operation is includ
Designing Instructional Examples to Reduce Intrinsic Cognitive Load: Molar versus Modular Presentati
It is usually assumed that successful problem solving in knowledge-rich domains depends on the availability of abstract problem-type schemas whose acquisition can be supported by presenting students with worked examples. Conventionally designed worked examples often focus on information that is related to the main components of problem-type schemas, namely on information related to problem-category membership, structural task features, and category-specific solution procedures. However, studying
When are powerful learning environments effective? The role of learner activities and of studentsÂ’
The goal of this chapter is to outline a theoretical and empirical perspective on how learnersÂ’ conceptions of educational technology might influence their learning activities and thereby determine the power of computer-based learning environments. Starting with an introduction to the concept of powerful learning environments we outline how recent developments in information and communication technologies might be used to implement these environments technologically. In the next step we refer t
Goal Configurations and Processing Strategies as Moderators Between Instructional Design and Cogniti
In this article, we propose some augmentations of cognitive load theory (CLT) inspired by evidence from hypertext-based instruction. In particular, we focus on the role of goal configurations and processing strategies as moderators between instructional design and cognitive load. First, we describe pivotal assumptions of CLT and conceptual shortcomings related to these assumptions. Second, we review evidence from our own hypertext-based research that gives reasons for integrating configurations
Implementing the Challenge Based Learning in Classroom Scenarios
Our Challenge Based Learning (CBL) method can be described as a special form of problem-based learning, in which the problems are of realistic, open-ended nature. Additionally, CBL contains features of experiential and project-based learning approaches. CBL is supported by the provision of Digital Experimentation Toolkits (DExTs) which comprise materials, initial instructions, references to web resources and specific software tools. Within the COLDEX project, a number of remote sites which gener
The Use of Multiple Student Modeling to Parameterize Group Learning
Recent criticism of ITS research for neglecting social aspects of learning is constructively answered by a practical attempt to extrapolate student modeling and intelligent learning support to group situations. The central focus is on using individually assessed student models to anticipate and parameterize group learning situations. This requires the integration of knowledge from individual models. Aspects of system architecture and dialogue design are discussedbased on an example of a replicat
Designing and Supporting Collaborative Modelling Activities in the Classroom
Over the last ten years, we have observed an increasing interest of the “computers in education” and other related research communities in supporting not only individual learners but also learning groups. The most prominent scenarios in this line of research and development have certainly been centred around virtual learning groups using computerised communication and cooperation facilities. From a technology point of view, the focus of this work has been on synchronous and asynchronous inform
Integrating Collaborative Concept Mapping Tools with Group Memory and Retrieval Functions
The provision of shared visual representations is considered to be an important facilitator for creative processes in group working and learning scenarios. Although reusability is an inherent feature of computerised representations in general, a comparative analysis of existing tools shows clear deficits in this respect. We are convinced that reusability and thus sustainability of the results of co-constructive group work can be much enhanced by integrating visual environments with functions for
Constructive and Collaborative Learning Environments - What Functions are Left for User Modelling an
With constructive and collaborative learning environments being current trends in tutoring systems, the function of user modelling and intelligent support is not as well-defined as in traditional intelligent tutoring systems. For practical solutions, there tend to remain only some niches for the application of intelligent components. To investigate the practicability of intelligent functions, we have build a framework architecture that allows for the implementation of self-contained constructive
Towards a Pattern Language for Intelligent Teaching and Training Systems
Intelligent Tutoring Systems (ITSs) are usually based on similar fundamental structures. In contrast to this, software engineering techniques are seldomly used for realizing ITSs. In the last years, some approaches tried to change this: pattern mining took place; methods covering the specifics of ITS project development have been deployed. These approaches usually focus on a specific system type or on a certain application domain. What is missing is a combination of all the different approaches
Analysis Methods for Collaborative Models and Activities
A classification of analysis methods for CSCL systems is presented which uses as one dimension the distinction into summary analysis and structural analysis and as another distinction different types of raw data: either user actions or state descriptions. The Cool Modes environment for collaborative modeling enables us to explore the whole spectrum of analysis methods. Action logging is based on the MatchMaker communication server underlying Cool Modes. Example instances for several analysis met
The Remote Control Approach – An Architecture for Tutoring in Pre-existing Collaborative Applicatio
In this paper we present an architecture for the integration of tutoring and process scaffolds into existing collaborative applications. The architecture allows to combine existing research results concerning collaborative processes and their formalization, and existing and tested collaborative learning environments. The architecture allows controlling the learning environments either by a human or a pedagogic agent. Both types of tutors are using the same set of primitives – either via an intu

Analysis and Intelligent Support of Learning Communities in Semi-structured Discussion Environments
Conventional discussion environments provide the technical platform for distributed discussion and collaboration, but apart from some statistical data collected, rarely provide information about the collaborative interactions taking place within the environement or even support the discussion by stimulating the learning setting according to the current situation. In this article we present our approach for intelligent support of groups of learners in distributed web-based discussion environments
