In this paper we focus on some of the findings of the science education research community in the area of representations and problem solving. Problem solving depends on the construction and manipulation of mental models (internal representations) in the mind. A large knowledge base (declarative, procedural, strategic, situational, and schematic…

Considers the cognitive mechanisms available to individuals which enable them to operate successfully in different parts of the mathematics curriculum, such as children's arithmetic shows divergence in performance. Explains how students cope with the transition to advanced mathematical thinking in different ways, leading once more to a diverging…

Examines the place of mental models in the process of knowledge construction, particularly by the relationship between mental models and computer models in that process. Analyzes and discusses children's use of spreadsheets to build their own computer models. Suggests that the process of building models on a computer may provide direct support to…

This study sought to discover differences in knowledge and knowledge organization between medical students and physicians. A total of 4 fourth-year students who had completed their pre-clinical courses, 4 fifth-year students who had just finished their internship in internal medicine, and 4 internists with an average of 20 years of experience were…

Describes an exploratory study on the acquisition and use of knowledge representation skills and structures by sixth-graders, supported by a computer-based learning environment. Results indicated that symbolic structures can be taught successfully, and that students using them in the context of instructional tasks perform at the higher band of…

Explores some speculative hypotheses on states of knowing and learning, and how these states and processes might be applied to artificial intelligence and expert systems development. (JKP)

A cognitive or internal representation refers to an organized system of information which reflects certain, but not all, of the information about reality being represented. This paper considers various opinions, controversies, and debates about what representation is, how it comes about, and what forms of representation can be distinguished. The…

This book focuses on three particular context-specific accounts of scientific thinking. The first section of the book presents research focused on extending knowledge of the fundamental components of scientific thinking. In the second section, research is presented that is focused primarily on how to build a structure for scientific thinking in…

This book brings a philosophical perspective to the topic of children's thinking. It attempts to answer the questions of what it is to think and understand, and how children do so. The book provides an introduction to the philosophy of education as it relates to children's understanding, and is careful not to assume any previous philosophical…
