In this study Piaget's method of the clinical interview was used to examine children's understanding of rotation about apoint at three age levels (6, 7, and 8). In two half-hour sessions, subjects (N = 108) were given four tasks: (1) an adaptation of Piaget's locus and circular motion experiment, and tasks concerned with (2) the circle as a locus…

The purposes of this study were to investigate the concepts of reading of first-grade and third-grade children, to describe the relationship of these concepts to the children's intelligence and reading achievement, and to investigate the differences between the concepts of reading of first and third graders. The subjects for the study were 30…

This study was planned to examine differences in the ability to stop and think, and knowledge of comparative concepts, among children who succeeded or failed in solving verbally presented class inclusion problems. Thirty third-grade boys were classified as non-Inclusion subjects, and 30 others as Inclusion subjects. The children were classified as…

Presented are sample activities from two workbooks and a teacher's guide designed to teach basic concepts to trainable mentally retarded students in the Philippines. Activities are explained to focus on such tasks as visual discrimination, direction following, imitation, auditory discrimination, matching, memory and number concepts. Case studies…

Reported is a study to determine the feasibility of teaching selected concepts related to the particle nature of matter to students in grades 2-6. The lessons developed for this study did not require a high student reading ability, did not require more than one-half hour of time, included the use of analogous mechanical models whenever possible,…

Investigated was the lateral asymmetry in children's hemispheric brain functioning during performance of Piagetian and curriculum related tasks. Six subproblems were investigated. Eighteen right-handed children, ages six to eight years old, were given electroencephalograms while performing a battery of tasks: Piagetian conservation tasks,…

This study investigated the extent to which certain aspects of the structure of a learner's memory following instruction corresponded with the structure of the instructional material. Content structure was represented using digraph theory. The digraph analysis revealed a formal structure built substantially on six specific concepts. Cognitive…

The practice of psychological intervention often relied on the ability of the therapist to understand how clients maintain a sense of relatedness to their world. Despite the many discontinuities of self-identity that affect the lives of clients, the success of therapy depends on clients' abilities to connect with human and nonhuman objects in…

Fifty first- and second-grade children's understanding of logico-mathematical relations were assessed using selected Piagetian tasks to test four hypotheses. The children's abilities to conserve numbers were compared to the means of mathematics concept scores and total mathematics scores of the 1972 Stanford Achievement Test, Form A. The…

This study investigated the effect of various sequences of examples and non-examples in facilitating geometric concept learning among educable mentally retarded (EMR) elementary and middle school children. Four instructional sequences were compared: wide variety with paired examples and non-examples, wide variety with each instance presented…

The purpose of this study was to compare the level of concept attainment achieved by students enrolled in a Physical Science Study Committee (PSSC) physics course with that achieved by students enrolled in a traditional high school physics course. A sample of 265 PSSC students and 219 enrolled in the traditional course participated. The instrument…

The purpose of this study was to investigate the degree to which teacher identified noncollege bound high school biology students have developed the ability to identify and to apply selected princepts of biology. To investigate this a multiple-choice test was developed that measured the ability to identify and apply selected princepts of biology.…

This study attempted to ascertain if the elements perceived in the physics concepts of mass and weight differed for students of different cultural backgrounds. Responses of two matched groups of 19 students each, one from the United States and the other from Taiwan, were studied; students were given word association tests and a physics problem set…

The research reported was associated with an early stage of developing a subunit of a curriculum within the framework of the Audio-Tutorial (A-T) Elementary Science Project at Cornell University. The research consisted of two parts: the development of an instructional unit for second-grade pupils and the formative evaluation associated with it.…

This dissertation reports the results of a one-year pilot study conducted to determine the feasibility of a small group-discovery method with a class of college freshmen studying calculus. The class consisted of twelve volunteer students who had A or B grades in their high school mathematics courses. The pilot class scored slightly better on a…
