Disciple is a shell for developing intelligent agents where an expert teaches the agent how to perform domain-specific tasks in a way that resembles the way the expert would teach an apprentice. This paper discusses the application of Disciple to the development of educational agents that generate test questions for students, together with hints, answers and explanations, and assist in the asse...

Cost-Sensitive Learning is a type of learning in data mining that takes the misclassification costs (and possibly other types of cost) into consideration. The goal of this type of learning is to minimize the total cost. The key difference between cost-sensitive learning and cost-insensitive learning is that cost-sensitive learning treats the different misclassifications differently. Costinsensi...

BACKGROUND Reliable models for massive hepatectomy in the mouse are required for experimental liver research. METHODS We analyzed anatomical findings in 100 mice following massive hepatectomy induced by liver reduction >70%. The impact of various factors in the different models was also analyzed, including learning curves, operative time, survival curves and histopathological findings. RESU...

The aim of the project is the development of an innovative, Open Source-based eLearning portal, which provides high scalability and versatility, as well as it is easy to upgrade; it aims at meeting some changeable requirement in the field of distance learning (yearly or even monthly innovation). The modular structure and flexibility provided by the portal makes this system adaptable to any kind...

This paper is an attempt to develop a distance learning model grounded upon a strict integration of problem based learning (PBL), dynamic knowledge networks (DKN) and web tools, such as hypermedia documents, synchronous and asynchronous communication facilities, etc. The main objective is to develop a theory of distance learning based upon the idea that learning is a highly dynamic cognitive pr...

Problem-based learning (PBL) is perhaps the most innovative instructional method conceived in the history of education. PBL was originally designed to respond to the criticism that traditional teaching and learning methods fail to prepare medical students for solving problems in clinical settings. Instead of requiring that students study content knowledge and then practice context-free problems...

Introduction The origins of problem-based learning (PBL) probably go back to 1920s. Celestin Freinet, a primary school teacher, returned from World War I to his village in south-east France. Due to his injuries, he was too breathless to speak to the class for more than a few minutes, so he created a new system of learning. This new system encouraged his pupils to take control of their own studi...
