The purpose of this study was to empirically test a set of predictions implied by the Model of Conceptual Learning and Development using the concept of cutting tool. Four subtests were developed to assess a subject's ability to perform at each of four successive levels of concept attainment (concrete, identity, classificatory and formal). In…

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…

Piaget's model of children's conceptual learning and development was compared with Klausmeier's Conceptual Learning and Development (CLD) model in a longitudinal study. The CLD model suggests four successive levels of concept learning: (1) concrete--recognizing an object which has been encountered previously; (2) identity--recognizing a known…

Theory and research regarding four levels of concept attainment and three uses of concepts as specified by the conceptual learning and development (CLD) model are described. The strategy and objectives of a longitudinal assessment of children's conceptual learning and development are presented. Perspective is provided regarding the role of the…

This document describes the Conceptual Learning and Development (CLD) model of concept formation. According to the CLD analysis, a single concept is learned in the following successive levels of attainment: concrete, identity, classification, and formal. The four levels are considered applicable to concepts that are defined (or could be defined)…

A model of conceptual learning and development that provides a framework for studying the course of cognitive development throughout the school years and also studying the learning concepts across short time intervals is discussed in this paper. The theory includes five main propositions. First, children learn four successively higher levels of…

Theory and research regarding four levels of concept attainment and three uses of concepts as specified by the conceptual learning and development (CLD) model are described. Assessment batteries were developed to assess each child's level of concept attainment and also the related use of the concepts equilateral triangle, cutting tool, and noun.…

The Conceptual Learning and Development (CLD) Model specifies four levels of concept attainment (concrete, identity, classificatory, and formal) and three uses of concepts (problem solving, subordinate-supraordinate, and principles). Longitudinal and cross-sectional studies of concept attainment may be conducted. The results of this study of 300…

Each of these citations (over 200 technical reports are theoretical, working, and practical papers) is annotated in a listing arranged by program and project within the program. Projects under Program 1, "Conditions and Processes of Learning," are titled Situational Variables and Efficiency of Concept Learning; Motivation and Individual…

In this essay, research done on concept learning is discussed. The study analyzes concept learning as one form of learning, formulating guidelines for teaching concepts, and describes the abilities underlying the attainment of concepts. An analytical model is presented; various operations such as concrete concepts and identity concepts are…

A tri-level structure of cognitive operations in concept learning is proposed, based on results of controlled experimentation and factor analytic studies. Global strategies in concept attainment are hypothesized to consist of three phases: attending to the situation, searching for information, and processing and using the information. Further,…

Research has shown that a behavior may be acquired through observing and imitating a model. A behavior which has already been acquired may be inhibited, disinhibited, or elicited by observing and imitating. A definition of imitation is given, and the effects of imitation on learning and performance are summarized. Research on factors which affect…
