Investigates Inhelder and Piaget's claim that ages six to nine or ten represent a stage in children's learning of the concepts of all and some. (HM)

The development of the concept of matter was explored in children aged 3-13. Eighty four children were asked to classify four sets of objects and matter and to explain their classifications during interviews. Younger children tended to classify using a mixture of extensive properties (properties of objects) and intensive properties (properties of…

Reviews research in the area of scientific classification of botany concepts. The acquisition, transfer, and ability to use cognitive skills were investigated. (CP)

Constructed response and multiple choice modes of programed instruction were compared. Both formats enhanced classification performance; the effect was greatest when the criterion test was in the same mode as the instruction. (AL)

Explored the development of hierarchical classification and the age at which this ability appears fully developed. Two measures of hierarchical classification ability were administered to primary, elementary, junior high and high school students. Discusses results which support Piaget's contention that this ability is not developed until late…

The purpose of this study was to investigate whether success in the Science - A Process Approach (SAPA) process of classification designed for primary grade children is contingent upon the children's developmental level as defined by Piaget's theory. The investigators sought to determine whether children who had reached the concrete operational…

This thesis reports a study of the effects of two types of advance organizer instruction, expository (EO) and guided self-discovery (GSDO), in teaching hierarchical classification or relations to preschool children. In the study, four experimental and one control group received three 25 minute instructional sessions. Using the same materials,…

This study investigated a problem within the theoretical structure of cognitive development proposed by Jean Piaget, and used the concepts of classification and projective spatial relationships to investigate the nature of attainment and sequencing of three corresponding logical and infralogical groupings according to the models proposed by…

This book articulates and defends the "theory theory" of cognitive and semantic development: the idea that very young children just beginning to talk are engaged in profound restructurings of several domains of their knowledge. These restructurings are analogous to theory changes. The children's early semantic development is closely tied…

This document outlines a theory of learning and education for the teaching of mathematics. The theory is termed a cognitive taxonomy. The taxonomy, developed over a 15-year period, is based on the connection between mathematical material and pupils' reactions to it. The function of this connection is termed a process. The taxonomy is based on the…

The learning of different school subjects (history, English, poetry appreciation, creative writing, reading, elementary school mathematics, geography, and modern languages) can be evaluated qualitatively, using the Structure of the Observed Learning Outcome (SOLO) Taxonomy. The taxonomy is structured into five major levels, with transitional…

Teachers everywhere are being held accountable for their professional actions through the test-driven curricula sweeping the nation. The National Council for the Accreditation of Teacher Education (NCATE, 2002) makes it clear that promotion of reflective practice is an important component of teacher education programs. This multiple case study…

Examines operations of generalization, identification, discrimination, and synthesis in mathematical concept development from early childhood to late adolescence according to Vygotsky's theory of development. (MDH)

The Model of Conceptual Learning and Development (CLD) is an analytical, descriptive model. It defines four levels of concept attainment and the possible uses and extensions of attained concepts, specifies the cognitive operations involved in learning concepts at each of the four levels, and postulates internal and external conditions of learning…
