The purpose of this research is to show that the logical formula for equivalence, (A=A; but is not A'), originates in the early manual actions of the young child. Having two hands that are bilaterally opposed and initially function in bilaterally symmetrical action might serve to structure the form of early sensori-motor experiences and this…

This study investigated developmental differences in the use of the common features abstraction strategy and the exemplar learning strategy for concept acquisition. Subjects were 30 second graders and 30 fifth graders. The concepts to be learned were two categories of artificial animals which differed on five dimensions. Each dimension had three…

It is generally conceded that there is much for a child to learn while attending nursery school, but the teacher is often unsure as to what type of curriculum or program will best assure such learning. Specifically, although play has been part of all nursery school programs, it is questioned whether spontaneous play (that is, relatively…

This book presents a theory of child development and learning and explores the implications of this theory for early childhood education. The theory is based on the Piagetian premise that the acquisition of knowledge is the result of an active process of construction. The child mentally transforms the environment by relating new information to…

This paper examines whether language development can be understood epigenetically in the same manner and based on the same principles with which Piaget has analyzed intellectual-cognitive development generally. The study is subdivided into four parts: (1) some principles in Piaget's system (the epigenetic principle, the genetic circle, and the…

Examined was the effectiveness of training four severely and profoundly retarded children (3-6 years old) to improve their level of functioning on a measure of object permanence and to demonstrate generalization to other areas of sensorimotor intelligence. Ss were given a pretest and posttest on the I. Uzgiris and J. Hunt instrument which consists…

This final report describes a project begun in 1962 which was designed to analyze the effect of home and maternal influence on the cognitive development of urban preschool children evaluated when they were four years old. The research group consisted of 163 mother-child pairs from three socioeconomic status levels: middle class, skilled working…

In order to investigate developmental changes in multiple classification, a matrix task was administered to 80 kindergarten first, second, and third grade children. Correct solution of the incomplete matrices, comprised of three pictures in a row and three pictures in a column meeting at a blank intersection, required identification and…

This monograph contains the 24 papers presented to the Third Annual UAP (University Affiliated Program) Conference on "Piagetian Theory: The Helping Professions and the School Age Child." Dr. Mary Ann Pulaski gave the major morning address on "The Importance of Ludi Symbolism (Make Believe Play) in Cognitive Development." The…

This document is an English-language abstract (approximately 1,500 words) of a book containing the results of many years of experimental research aimed at ascertaining the intellectual ability of students in the junior grades to assimilate theoretical knowledge. Chapter one analyzes the problem of the age peculiarities of children. The author…

Performance data for 42 subjects pertaining to seven course objectives and ten propositional logic tasks were analyzed for hierarchical relationships using ordering theoretic technique. The resulting hierarchy indicated that simple implication and particular contraposition propositional logic tasks were prerequisite to some course objectives. This…

Suggests that the process view of science is flawed. Argues that (1) it is superficial and misleading to portray the method of science in process terms; (2) many of the processes have no special association with science; and (3) there is no evidence that performance is improved. Speaks of the challenge facing science education. (RT)

Examines the problem-solving strategies of experts and novices. Summarizes the overall performance of four experts and eight novices. Examines several protocols in depth in order to show how subjects introduced new terms and relationships during problem solving sessions. Compares the strategies of expert and novice problem solvers.

Illustrates how one can discover structure in mental abilities where none was obvious. Reports that two classes of processes are used to form images. Indicates that imagery is carried out by multiple processes, not all of which are implemented equally effectively in the same part of the brain. (RT)

Attempts to show that not only can density be taught to lower ability pupils but that by doing so, there is the possibility of assisting pupils to develop their reasoning powers. Lists teaching activities that help in this process. (CW)
