Measuring the responsiveness of e-learning materials to varying learning styles using EDUSA method
The strength of the acceptance by a particular e-learner for a particular e-learning material depends on two main factors: 1) the ability of the e-learner to vary his or her learning style, especially in terms of pace, and 2) the ability of the e-learning material to offer a sufficient responsiveness in adaptation to the corresponding learning style of the particular e-learner. E-learning materials that better adapt to the varying learning styles of e-learners have a larger "contact area" than t

This paper presents a multi-dimensional learning style model and a system specification to automatically generate adaptive courses using the aspect oriented technique.
Advantages and disadvantages of e-learning at the technical university
The term Electronic Learning or e-Learning is being used in Russia rather rarely. It integrates a number of terminological notions in the sphere of application of modern information and communication technologies in education such as multimedia, education on the base of web-technologies, etc. Teachers and learners must realize that new opportunities are offered by modern on-line communication. A person with basic Internet and Web skills is open to a new world of knowledge, from free Web surfing
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
A Parallel Grid-based Implementation for Real Time Processing of Event Log Data in Collaborative App
Collaborative applications usually register user interaction in the form of semi-structured plain text event log data. Extracting and structuring this data is a prerequisite for later key processes such as the analysis of interactions, assessment of group activity, or the provision of awareness and feedback. Yet, in real situations of online collaborative activity the processing of log data is usually done offline since structuring event log data is, in general, a computationally costly process
An Experimental Study on Peer Selection in a P2P Network over PlanetLab
Peer selection is an important aspect in many P2P applications
requiring efficient assignment and execution of
jobs to peer nodes and search and file transfer, among others.
Due to increasing interest of using P2P systems for distributed
computing, peer selection is taking relevance and
several models have been proposed in the P2P literature.
Yet, there are very few experimental studies for peer selection
in P2P networks deployed in real large scale networks.
In this work we present an experimen
Students Activity in Computer-Supported Collaborative Problem Solving in Mathematics
The purpose of this study was to analyse secondary school students (N = 16) computer-supported collaborative mathematical problem solving. The problem addressed in the study was: What kinds of metacognitive processes appear during computer-supported collaborative learning in mathematics? Another aim of the study was to consider the applicability of networked learning in mathematics. The network-based learning environment Knowledge Forum (KF) was used to support students collaborative problem
The evolution of research on collaborative learning
For many years, theories of collaborative learning tended to focus on how individuals function in a group. More recently, the focus has shifted so that the group itself has become the unit of analysis. In terms of empirical research, the initial goal was to establish whether and under what circumstances collaborative learning was more effective than learning alone. Researchers controlled several independent variables (size of the group, composition of the group, nature of the task, communication
The Semantic Aspects of e-Learning: Using the Knowledge Life Cycle to Manage Semantics for Grid and
The aim of bringing semantics to learning content and services is to enable large scale collaboration of e-learning activities over the Grid infrastructure.
As machines and software applications will be ubiquitously involved in enabling and facilitating this collaboration, it requires a common understanding of the domain, in particular at the conceptual level, so that both computers and human participants of the e-learning activities understand and are able to communicate among themselves thoug

Cognitive factors related to user involvement with computers and their effects upon learning from an
Cognitive theories proposed to explain the high motivation to use, and deep involvement with computers, often found in schoolchildren suggest three main factors. They are: desire in the user to control the computer; the user responds to a perceived challenge from the computer; and the user wishes to explore the complexity of the computer software. The paper describes an experiment using a specifically developed piece of software to investigate these factors and to assess their effects on involve

A note on organizational learning and knowledge sharing in the context of communities of practice
The knowledge management (KM) literature emphasizes the impact of human factors forsuccessful implementation of KM within the organization. Isolated initiatives for promoting learning organization and team collaboration, without taking consideration of the knowledge sharing limitations and constraints can defeat further development of KM culture. As an effective instrument for knowledge sharing, communities of practice (CoP) are appearing to overcome these constraints and to foster human collabo
