Modelling students’ knowledge organisation: Genealogical conceptual networks

Constraining questions about the organisation and representation of conceptual knowledge.

In this article we assume a domain-specific organisation of conceptual knowledge and consider two questions: How does this architecture constrain further assumptions that might be made regarding (1) the organisation of conceptual knowledge in the brain, and (2) the representation of conceptual knowledge in the brain? Data from category-specific semantic deficits, functional neuroimaging, and ap...

Taxonomic and Thematic Organisation of Proper Name Conceptual Knowledge

We report the investigation of the organisation of proper names in two aphasic patients (NBC and FBI). The performance of both patients on spoken word to written word matching tasks was inconsistent, affected by presentation rate and semantic relatedness of the competing responses, all hallmarks of a refractory semantic access dysphasia. In a series of experiments we explored the semantic relat...

Students’ conceptual knowledge of energy and momentum

We investigate student understanding of energy and momentum concepts at the level of introductory physics by designing and administering a 25-item multiple choice test and conducting individual interviews. We find that most students have difficulty in qualitatively interpreting basic principles related to energy and momentum and in applying them in physical situations. The test development proc...

Conceptual Modelling for Knowledge - Based Systems

Enterprise Knowledge Management and Conceptual Modelling

Turbulence is in the nature of business environments. Changes brought about because of different requirements such as social, political, technical and economic, exert pressures on organisations to respond in a timely and cost effective way to these challenges. In such an unstable environment information system developers are challenged to develop systems that can meet the requirements of modern...
