TORTIS (Toddler's Own Recursive Turtle Interpreter System) is a device which can be used to study or nurture the cognitive development of preschool children. The device consists of a "turtle" which the child can control by use of buttons on a control panel. The "turtle" can be made to move in prescribed directions, to take a…

This paper briefly reviews the literature concerning the Paiget-Burner debate over the roles of identify and reversibility rules in conservation acquisition, and describes an experiment designed to determine whether one group of rules is more closely related to conservation than the other. A group of children, aged 4-6 years, received tests of…

Fifteen research reports related to mathematics education are abstracted and analyzed. The reports abstracted were selected from nine educational journals including several published outside the United States, and deal with a wide variety of topics. Three articles deal with concept formation, three with task analysis or instructional sequencing,…

This paper describes a Piagetian-based evaluation measure and results obtained from the use of this measure with 1260 pre-kindergarten inner-city children. The children were enrolled in a program designed to develop their readiness skills. Family income, limited educational opportunities of adult members of the family, and dependency on public…

Presented is the Virginia State Education Department's curriculum development guide for teachers of the trainable mentally retarded (TMR). Briefly considered are long range goals and characteristics of the TMR child, curriculum design factors and the role of the teacher. The bulk of the document is comprised of activities for primary,…

Many preschool children with developmental delays in cognition and language are in the preoperational stage as defined by Jean Piaget's theory of cognitive development. The preoperational stage is divided into the preconceptual and the intuitive phases. During the preconceptual phase, the preschooler is unable to form true concepts and often…

A process-oriented research strategy was employed to examine relations among various aspects of the early home environment and children's language development. The home environments of 65 infants were assessed when the infants were 12 and/or 24 months old with the Home Observation for Measurement of the Environment (HOME). HOME includes six…

The Cognitively Oriented Prekindergarten Experience (Project COPE) is a preschool effort to accelerate the development of children from predominantly low-income families. This program was nationally validated as an ESEA Title III project and has received support from the U.S. Office of Education as a National Developer/Demonstrator site. Having…

As an integral step in a comprehensive, four year longitudinal analysis of concept development, a series of logical concept tasks based upon Piagetian theory, and suitable for administration to individuals five years of age or older, are described. The developmental focus was the logical groupements associated with the concrete operations period…

The hypothesized relationship between an individual's age, educational background, and ability to understand aspects of semantic ambiguity was investigated in this study. The 90 subjects included ten students in each of grades two, four, six, eight, and ten, as well as ten college undergraduates, ten graduate students, ten high school graduates,…

The primary purpose of this study was to establish normative data for the cognitive style behaviors of children from kindergarten through the ninth grade. Approximately 400 students served as subjects. The measures used were a free response pictorial-, a multiple choice pictorial-, and a multiple choice verbal-test. Cognitive style behavior was…

This paper attempts to clarify some of the issues raised in the author's earlier paper, "A Theoretical Perspective on the Relationship between Bilingualism and Thought" (Working Papers on Bilingualism, No. 1), as a response to Gerald Neufeld's critique, which appeared in No. 2 of the same series. The present paper argues that Neufeld mistakenly…

This study explored the developmental changes in children's effective utilization of verbal versus pictorial stimuli in forming connections between stimulus and response elements in a paired-associate task. A total of 112 children (56 males and 56 females), half of them 4-year-olds and half 8-year-olds, were tested under eight conditions involving…

A study of 128 third graders was made to determine whether audiovisual media does facilitate cognitive development by comparing the effects of learning a mental skill from a filmed demonstration of that skill with learning from more active kinds of experience. The mental skill was the ability to mentally transform mental images by rotating them…
