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…

In studies conducted in the Baltimore City Public Schools by the Office of Pupil and Program Monitoring and Appraisal (OPPMA), pre-kindergarten pupils were found to be "growing scholastically". A program, Early School Admissions Program (ESAP) was based on nine objectives established to prepare pre-schoolers for "reading…

It was hypothesized that there are significant differences in intellectual patterns between black and white populations which can be demonstrated on the Wechsler Adult Intelligence Scale (WAIS). A one-way analysis of variance was performed on the subjects' scores on the WAIS subtests and the Verbal, Peformance and Full Scale IQ using the ethnic…

The purpose of this publication is to help teachers identify the levels which children have attained in their thinking as they express their attitudes, values, and behaviors through oral language. Provided are (1) sample questions applicable to various maturity levels to enable teachers to gauge the level of difficulty of their classroom…

Based on the more general principle that all thinking (including reasoning) is basically perceptual in nature, the author proposes that visual perception is not a passive recording of stimulus material but an active concern of the mind. He delineates the task of visually distinguishing changes in size, shape, and position and points out the…

Presents a discussion illustrating student reasoning while using LOGO to draw tilted squares and rectangles. Suggests that teachers recognize that many students use visual imagery to reason and discuss visual reasoning with students. Gives examples of tasks to promote discussion. (MDH)

Presents three typical lab activities involving the breathing rate of fish, the behavior of electromagnets, and tests for water hardness to demonstrate how labs can be modified to teach process skills. Discusses how basic concepts about experimentation are developed and ways of generating and improving science experiments. Includes a laboratory…

A 2-year study at the University of Sherbrooke (Quebec) investigated the changes in six medical students' clinical reasoning processes as they participated in a problem-based learning (PBL) curriculum. In each year, students performed a think-aloud protocol with two medical case problems to solve, one in cardiology and one in urology. In the…

This study compared the acquisition of an initial place value skill when presented in a concrete, semiconcrete, abstract teaching sequence to acquisition of the same skill when presented at the abstract level only. The 24 subjects were elementary and middle school students (ages 8-13) with learning disabilities who were randomly assigned to…

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…

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…

This document accompanies the Conceptual Learning and Development Assessment Series I: Equilateral Triangle, a test constructed to chart the conceptual developemnt of individuals. As a technical manual, it contains information on the rationale, development, standardization, and reliability of the test, as well as essential information and…

This document accompanies Conceptual Learning and Development Assessment Series II: Cutting Tool, a test constructed to chart the conceptual development of individuals. As a technical manual, it contains information on the rationale, development, standardization, and reliability of the test, as well as essential information and statistical data…

The impact of higher education on the cognitive and social development of students was studied in three experiments. A longitudinal comparison of moral reasoning development in the four years after high school among those who did and did not attend college was undertaken. Instruments used were the Reflective Judgment Questionnaire, the Concept…

Six experiments examined the problem-solving behavior of normal and mentally retarded (MR) children with a two-choice discrimination learning situation: the effects of stimulus similarity upon types of solutions utilized by MR children; the role of redundant cues in the discrimination learning of MR subjects with differing mental ages; the…
