Concepts are where the foundation of scientific knowledge and thought structures are laid. Thanks to concepts, distinctions or generalisations about an event or an entity are formed and thought structures are formed in our minds. In this study, it was aimed to determine the associations in the minds of secondary school 6th grade students about the…

The number sequences describe a hierarchy of students' concepts of number. This research uses two defining cognitive structures of the number sequences--units coordination and the splitting operation--to model middle-grades students' abilities to write linear equations representing the multiplicative relationship between two unknowns. Results…

This paper addresses contemporary (i.e., postmodern) concerns with the disintegration of meaning and fragmentation of knowledge. As society continues to move towards increased specialization and separation of disciplines, people are becoming increasingly disconnected from the broad connecting conceptions within the disciplines, i.e., the patterns…

This paper presents two general approaches to the assessment of knowledge structures, the first of which entails the building of empirical evidence to support cognitive theory. This type of assessment is concerned with attempting to prove the existence of various knowledge structures; that is, evidence that leads to the construct validity of these…

The controversial nature of the knowledge base of educational administration is discussed in this paper. Included are a definition of professionalism, a discussion of how to build and develop a knowledge base, and a review of the obstacles to knowledge base development. Elements of a consensual knowledge base include theory, practice, and other…

Explicit representation of relations plays some role in virtually all higher cognitive processes, but relational knowledge has seldom been investigated systematically. This paper considers how relational knowledge is involved in some tasks that have been important to cognitive development, including transitivity, the balance scale, classification…

Therapy provides a useful model for teaching critical thinking by placing thinking processes in the context of the whole person. Critical thinking is grounded in the language skills of the student as the student attempts to construct a structure of reality that is well-adapted to the student's relational contexts. The didactic model of teaching…

This study presents a quantitative method for scoring concept maps generated by students learning introductory college chemistry. Concept maps measure the amount of chemical information the student possesses, reasoning ability in chemistry, and specific misconceptions about introductory and physical chemistry concepts. They provide a visualization…

The proposals concerning working memory outlined in this paper involve the architecture of working memory, the reasoning mechanisms that draw on it, and the ways in which working memory may develop with age. Ways of assessing task demands and children's working memory capacities are also considered. It is noted that there is long-standing evidence…

This paper proposes a model for teaching and learning complex thinking skills developed from a synthesis of theories and research. The model functions like a concept map or a graphic organizer with five major components, each discussed in this paper: (1) presence of complex authentic life situations within a context; (2) activation and execution…

Three different theory of mind tasks were conducted with 4- to 8-year-old Quechua peasant children in the Peruvian Andes. The study investigated the ways in which children in preliterate cultures think and the possibility that they think differently than children in literate cultures. The tasks included: (1) a false-belief task, which tested the…

The pursuit of a science of mind has been marked by persistent conceptual tension. At one pole, exemplified by Piaget, the mind is characterized in terms of overarching principles. At the other end of the continuum, theory is more concerned with modeling particulars, as represented by the information processing model. This paper explores the…

A study was conducted in Israel to determine effects of external similarity in problem structure on students' responses. Fifty students from each of the 7th, 8th, 10th, and 12th grade levels were presented with three problems involving successive divisions that were similar in structure. The problems asked separately whether the processes of…

The relationship between perceptual structure and individual differences in cognitive ability was studied through a computerized inductive reasoning task performed by 100 college undergraduates at Cleveland State University (Ohio). Measures included two psychometric tests and a set of four computerized cognitive tasks. Two components of perceptual…

The paper presents the thesis that experienced physicians, while diagnosing routine cases, are operating upon knowledge structures that are distinctively different from those of novice physicians and students. In the course of their medical training, students develop rich, elaborated causal networks, explaining the causes and consequences of…
