This study examined developmental changes in concept formation, rule switching, and perseverative behaviors of children in the WCST by altering visual features of the test and using a new test score--the "zigzag" error score--which shows the number of shifts made between two incorrect concepts or rules. Instead of the original four 3-dimensional…

Cognitive, home, and family factors that theoretically could influence whether or not preschoolers' interests were focused on domains characterized by the acquisition of knowledge concerning object concepts (e.g., dinosaurs, horses) were assessed in a short-term longitudinal investigation of 211 4-year-olds. Boys were six times as likely as girls…

The present study investigates the development of children's ability to make inferences about a peer's mental state. In this study 48 eight-year-old children, 49 ten-year-old children and 44 adults observed and analyzed short video sequences, extracts from a socio-cognitive interaction between two children working on a mathematical task. The…

The objectives of this study were to: examine the potential interaction between students' epistemological beliefs and placement in a simulation condition (constructivist versus non-constructivist) on conceptual development; and to assess whether a constructivist computer simulation experience would result in a greater degree of conceptual change…

This paper demonstrates a method for constructing long variables using items that elicit partically correct responses across ages. Long variables may be defined by students at different ages (year levels) attempting common items within a test containing other items considered to be appropriate for each age or year level. A developmental model of…

This research explores the moment-by-moment understanding students exhibit in the learning of a non-physical science domain--the human circulatory system. The goal was to understand how students learn by capturing the nature of their initial mental models (naive conceptions), and by seeing how new information gets assimilated into their mental…

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…

Suggestions are given relating to having plants and animals in the classroom to stimulate development of the understanding of the concept of being alive, a concept not really understood by children under age nine. The research reviewed promotes firsthand experiences to help form concepts of living and nonliving, of identity and causality. (EB)

A collaborative research study was designed to facilitate, at the local school level, a mathematics teacher's development of a "constructivist" pedagogy. This paper discusses the nature and influence of the teacher's professional beliefs on his attempts to create a classroom learning environment congruent with the principles of a constructivist…

This study focused on misconceptions related to light and vision. Researchers administered diagnostic tests about light, vision, and color before and after instruction to 227 fifth-grade students over a 2-year period. They also conducted 11 clinical interviews. The tests and interviews revealed that almost all students shared certain…

The purpose of this study was to determine how children at different ages understand the concept of temperature, examining particularly the logicomathematical aspects of the concept. In doing so, three developmental approaches were compared: (1) Piaget's structuralist approach; (2) Siegler's rule assessment approach; and (3) Anderson and…

To investigate young children's understanding of metaphorical language, 90 chidren from preschool to third grade were read stories ending with metaphorical sentences of varying degrees of difficulty--sentences representing more or less predictable story outcomes and differing in the complexity and explicitness of their figures of speech. After…

This book is intended to give teachers and student teachers a better understanding of the thinking of adolescent students in science lessons and to indicate the difficulties such students have in understanding the more abstract or formal ideas with which they are presented. It is practical in its orientation as the issues discussed are illustrated…

Reported is an investigation of the development of children's thinking in relation to biological education, involving over 200 twelve-year-old students from five comprehensive British schools. While the students' ability to name animals was considered "good," they had trouble recognizing drawings of plants and their understanding of…

Examines themes evident in children's and mother's definitions of illness to determine how views of illness develop. Subjects were 264 children (ages 6 to 12-11) and their mothers. Two issues were considered: (a) patterned similarity in illness definitions, and (b) developmental changes in illness concepts. (ED)
