A Framework for Agent-Supported E-learning
This paper presents a framework to describe the crossover domain of e-learning and agent technology. Furthermore it is used to classify existing work and possible starting points for the future development of agent techniques and technologies order to enhance the performance and the effectiveness of several aspects of e-learning systems. Agents are not a new concept but their use in the field of e-learning constitutes a basis for consequential advances.
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
A Place in Space
The students will use a "real" 3D coordinate system. They will have 3 axes at right angles, and a plane (the XY plane) that will be able to slide up and down the Z axis. The students will then be given several coordinates and asked to find these points in space. They will also be asked to find the coordinates of the 8 corners of a box with given dimensions.
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
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
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
Toward Cognitive Tutoring in a Collaborative, Web-Based Environment
A potentially powerful way to aid in the authoring of intelligent tutoring systems is to directly leverage student interaction log data. While problem-solving data has been used in the past to guide the development of tutors, such data has not been used as a means to directly construct an initial tutoring system model. We propose an approach called bootstrapping novice data (BND) in which a problem-solving tool is integrated with tutor development software through log files and that integration
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
CSCL Scripts: Modelling Features and Potential Use
The design of collaboration scripts is a new focus of research within the CSCL community. In order to support the design, communication, analysis, simulation and even execution of collaboration scripts, a general specification language to describe collaboration scripts is needed. In this paper, we analyse the suitability and limitations of IMS LD for modelling collaborative learning processes. Based on the analysis, we propose a CSCL scripting language. This paper presents the conceptual framewo
Facilitating collaborative knowledge construction in computer-mediated learning with structuring too
Collaborative knowledge construction in computer-mediated learning environments puts forward difficulties regarding what tasks learners work on and how learners interact with each other. For instance, learners who collaboratively construct knowledge in computer-mediated learning environments sometimes do not participate actively or engage in off-task talk. Computer-mediated learning environments can be endorsed with sociocognitive structuring tools that structure the contents to be learned and s
Measuring knowledge convergence: Achievement similarity and shared knowledge in computer-supported c
Learning in small groups may result in convergent knowledge outcomes or foster possible prior differences between learners. Few studies, however, measure convergence or divergence of knowledge as an outcome of small group learning. This contribution analyzes knowledge convergence/divergence as an outcome of learning in small groups with the concepts of achievement similarity and shared knowledge rooted in two different theoretical frameworks. Achievement similarity means that learners acquired s
Innovative pedagogical and psychological perspectives of podcasts
Podcasting, being a new form of audio distribution offering the possibility to be loaded on personal mobile devices from teachersÂ’, studentÂ’, universityÂ’s websites and blogs, is discussed as an activity with potential in learning and teaching. The existing and potential varieties of podcasts represent sources for learning, converging, socializing. In this paper, podcasting is supported as an innovative approach to stimulate university studentsÂ’ reflection, specifically on epistemic quest
Energy Transfer in Musical Instruments
This lesson covers concepts of energy and energy transfer utilizing energy transfer in musical instruments as an example. More specifically, the lesson explains the two different ways in which energy can be transferred between a system and its environment. The law of conservation of energy will also be taught. Example systems will be presented to students (two cars on a track and a tennis ball falling to the ground) and students will be asked to make predictions and explain the energy transfer m

Supporting information comparisons in example-based hypertext environments
Global comparisons of learning from hypertext and traditional text have yet failed to show major advantages concerning the effectiveness of hypertext learning. In the current paper it is proposed that an effective hypertext design needs to be based on thorough cognitive task analyses with regard to structures, processes, and resources that are required to benefit from a specific learning approach. This claim is illustrated by two experiments, in which we investigated two methods for supporting e

Redefining the Turn-Taking Notion in Mediated Communication of Virtual Learning Communities
In our research on social interactions taking place in forum-type tools that virtual learning communities use, we have found that the users have the following particular temporal behavior: they answer generally some messages situated in different threads in a very short time period, in a digest-like way. This paper shows this work pattern through a quantitative study and proposes an integration of this work pattern in a Forum-type tool developed for supporting the interactions of virtual learnin
Internet Scout Project
The Cyber Security Group at Pennsylvania State University is developing database software that can detect "attacks by malicious transactions" and repair the database with no interruption. This research paper proposes five different schemes for implementing such a system, with each one building on the previous. Some of the main goals for the schemes are automatic damage repair, attack isolation to prevent multiple attacks of the same type, and damage containment during the repair process. One of
