Despite technological advances that support wide-ranging access to and transfer of knowledge, practicing physicians continue to underutilize current biomedical literature. This paper explores the nature of clinically applicable medical knowledge through a structural analysis of clinical questions. The author analyzed a set of sixty questions, based on actual online search requests of practicing...

This paper describes the MATHESIS Ontology, which is part of the MATHESIS project that aims at the development of an intelligent authoring environment for reusable model-tracing math tutors. The purpose of the ontology is to provide a semantic and therefore inspectable and reusable representation of the declarative and procedural authoring knowledge necessary for the development of a model-trac...

Factors affecting performance on Base-10 tasks were investigated in a series of four studies with a total of 453 children aged five to seven years. Training in counting-on was found to enhance child performance on Base-10 tasks (Studies 2, 3, and 4), while prior knowledge of counting-on (Study 1), trading (Studies 1 and 3) and partitioning (Studies 1 and 4) were associated with enhanced Base-10...

Abstract Productive failure has shown positive effects on conceptual and transfer measures, but no clear procedural measures. It is therefore an open question whether, to what extent, productive methods may be used enhance the learning of skills. A typical study focuses a single, complex concept; in contrast, knowledge generally consists series less-complex steps. In this study, occasions were ...

Studies of complex dynamic control tasks (CDCTs) have revealed that when problem solvers learn about a system indirectly through observation (Berry, 1991; Lee, 1995), their procedural knowledge of the system is impaired relative to their declarative knowledge. However, when learning is through direct interactions with the system, then problem solvers declarative knowledge is impaired relative t...

Information security is an important aspect that should be considered during system development. Analyzing the specification of a system enables detecting flaws at early stage of a system development. An agent knowledge of the exchanged information and its nature is essential for analyzing systems. An agent can enrich its knowledge by receiving information as messages and producing new informat...

This paper examines procedural modeling as a tool for 3D modeling creation. Procedural modeling historically has been used for 3D visualization of natural features, but with the release of the software CityEngine in 2008, the technology can easily be adopted also in problem domains dealing with urban environments. Then, we will examine and compare two types of modeling, traditional and proc...

This paper aims at addressing the issues of knowledge representation in the area of learning design and adaptive learning. A specification of concrete learning design instances is usually context dependent and does not support reusability very well, thus we need to represent the knowledge that could help us in generating the instances dynamically. As we are dealing with learning design and adap...
