Improvement of JXTA protocols for supporting reliable distributed applications in P2P systems
In any distributed application, the communication between the distributed processes/nodes of the distributed systems is essential for both reliability and efficiency matters. In this work we address this issue for distributed applications based on JXTA protocols. After a careful examination of the current version of JXTA protocols, we observed the need for improving the original JXTA protocols, such as pipe services, to ensure reliable communication between peer nodes and the discovery and prese

Going Beyond the Problem Given: How Human Tutors Use Post-Solution Discussions to Support Transfer
Two studies investigated the role and effectiveness of post-solution, reflective dialogues in physics tutorials. The first study investigated the instructional roles of post-solution discussions, their relationship to problem-solving discussions, and features that predict learning. Seven tutors individually guided 15 students as they worked on problems in the Andes physics tutoring system. Tutors adapted the post-solution discussions to students' ability levels and their performance on the curre

Benefits of Virtual Characters in Computer Based Learning Environments: Claims and Evidence
Pedagogical theory of today gives high priority to social components of learning. Within the field of computer supported learning there are many attempts to acknowledge this. One approach involves the addition of virtual characters to electronic learning environments. Such character enhanced systems are the focus of the present article. Firstly, a systematic overview is given of pedagogical benefits that have been proposed in the literature regarding character enhancement of electronic learning

Introduction

This unit looks at how parents encourage the development of new skills in their children in the informal setting of the home. The use of video observation of small children by psychologists is analysed and some of the key concepts in developmental psychology that explain teaching and learning interactions between parents/caregivers and their children are explained.

7.349 From Molecules to Behavior: Synaptic Neurophysiology (MIT)
Like transistors in a computer, synapses perform complex computations and connect the brain's non-linear processing elements (neurons) into a functional circuit. Understanding the role of synapses in neuronal computation is essential to understanding how the brain works. In this course students will be introduced to cutting-edge research in the field of synaptic neurophysiology. The course will cover such topics as synapse formation, synaptic function, synaptic plasticity, the roles of synapses

Harmonization methodology for metadata models
Metadata allows systems, applications and users to manage and access resources without a need for interaction with the resource itself. For this reason, the administration and exchange of metadata is a central activity in systems that manage learning objects. Metadata considerations are fundamental when creating interoperable e-learning tools, and metadata standards have been among the very first learning technology standards to mature. This deliverable analyses a number of existing metadata spe

1.3 Empowerment and anti-oppressive practice

Empowerment can be defined as enabling service users to take action to improve their lives. From the point of view of service users, practitioners are often in positions of considerable power, particularly where decisions are being made about the delivery of services and around intervention in people's lives. To practise empowerment, social workers will need to focus on working with service users to engage them in the problem-solving process. Empowerment is linked with anti-oppressive practic
