This paper explores the methodological and epistemological implications of the relationships between R&D, policy and practice. The proposals towards "evidence-based policy and practice" are analysed with respect to this triangle from three angles: (1) meaning; (2) production; and (3) use of evidence. A comprehensive model of the…

Continuity of functions appears throughout the grades in South African high school (FET (further education and training)) topics as prescribed by the final draft of the Curriculum and Assessment Policy Statement. This article reports on the use of a combined framework of APOS (action-process-object-schema) and DCT (dual coding theories) to analyze…

In a series of well-known papers, Chi and Slotta (M. T. H. Chi, 1992, 2005; M. T. H. Chi & J. D. Slotta, 1993; M. T. H. Chi, J. D. Slotta, & N. de Leeuw, 1994; J. Slotta & M. T. H. Chi, 2006; J. D. Slotta, M. T. H. Chi, & E. Joram, 1995) have contended that a reason for students' difficulties in learning physics is that students…

At the beginning of the 21st century, a new social arrangement of work poses a series of questions and challenges to scholars who aim to help people develop their working lives. Given the globalization of career counseling, we decided to address these issues and then to formulate potentially innovative responses in an international forum. We used…

The main purpose of the study was to compare the effectiveness of 5E learning cycle model based instruction and traditionally designed chemistry instruction on 10th grade students' understanding of state of matter and solubility concepts. In this study, 119 tenth grade students from chemistry courses instructed by same teacher from an Anatolian…

With respect to the specificity and structure of epistemological beliefs, we contend that beliefs about knowledge are reflective of the multidimensional, multilayered, and interactive nature of knowledge. Here we present a model of the nested and reciprocal relations between domain-general and domain-specific epistemological beliefs. Additionally,…

Refines the basic entity model of information theory and extends it to analyze mathematically the physical symbol transformation characteristics, as well as energy-matter and cognition phenomena occurring in the human mind. Reviews existing theories; examines physical symbol subsystem, cognitive perspective, energy-matter subsystem; and discusses…

Presents arguments, based on Thomas Kuhn's work, that most research on rural and small schools proceeds from previous scientific achievements, and that researchers' (outsiders') preconceived and approximated reality forces the nature of rural and small schools into an inflexible box. Contains 40 references. (Author/SV)

Curriculum knowledge cannot be legitimized until its method of construction is examined. Dominant curriculum theories, those that are well established by tradition, usually provide research results reflecting a deterministic or imposed reality. The basic premise of this paper is that curriculum theorizing has, for the most part, been a utilitarian…

The world presented to our senses is essentially continuous in space and time. The simplest observations of children have shown that we are not born with ways of "breaking up" the world. The structures of our knowledge must be developed, and the major issue this paper considers is how those structures develop. The discussion focuses on Jean…

The use of structural equation modeling is discussed in testing a range of theories of learning and cognition involving the concept of a hierarchy of variables of increasing complexity. To illustrate this approach, one method is applied to Bloom's taxonomy to test the theoretical assumption of hierarchical organization. (Author/MSE)

Isolates domain-general decision-making (DM) processes in their specific instantiations in adult second-language acquisition (SLA). Some impediments to success in SLA may be artifacts of mature (adult) DM procedures. (Contains 29 references.) (JP)

Effective belief-desire reasoning requires both specialized representational capacities--the capacity to represent the mental states as such--as well as executive selection processes for accurate performance on tasks requiring the prediction and explanation of the actions of social agents. Compromised belief-desire reasoning in a given population…

This description of the Structure-Mapping Engine (SME), a flexible, cognitive simulation program for studying analogical processing which is based on Gentner's Structure-Mapping theory of analogy, points out that the SME provides a "tool kit" for constructing matching algorithms consistent with this theory. This report provides: (1) a…

This paper describes the Structure-Mapping Engine (SME), a cognitive simulation program for studying human analogical processing. SME is based on Gentner's Structure-Mapping theory of analogy, and provides a "tool kit" for constructing matching algorithms consistent with this theory. This flexibility enhances cognitive simulation studies by…
