The research literature suggests that the processes involved in language and cognitive development are similar in nature, especially during the early years. Both require some method for assimilation and accommodation of incoming stimuli, both appear to be continuous and hierarchical in nature, and both require the development and refinement of a…

Piaget's last works (1975, 1977, and 1980) add a dynamic aspect to his earlier exceptionally formal structural model. He portrays change in more functionalistic terms and describes conflict, referring to the process of perturbations and compensations to explain the regulations of the network of cognitive cycles. He suggests three types of balances…

Little is known about how teachers encourage memory activity and strategy use in children. In order to gain such information, 69 teachers of grades K through 6 were observed in five 30-minute periods. A total of 292 strategy suggestions and 15 instances in which the teacher attempted to suppress spontaneous strategy use were observed. Teachers…

Cognitive development proceeds through a series of four levels. The first is the single-class level, attained by infants at approximately 1 year of age. At the single-class level, concepts are based on element similarity or convention (for example, images and words for common objects). The second level is the relational level, attained by toddlers…

Most of the research on mathematical and scientific thinking has been concerned with uncovering knowledge structures and reasoning processes in people of different levels of competence. How these structures and processes are acquired has only recently become a major concern. Thus, some of the major research on mathematical and scientific thinking…

In a primary school in Dade County, Florida, disadvantaged kindergarten children were entering first grade without the receptive language and listening skills necessary to succeed academically. A practicum attempted to remedy this problem by stimulating kindergarten children's receptive language skills in vocabulary and listening comprehension.…

This study investigated the effects of analogy-based and conventional lecture-based instructional strategies on the achievement of four classes of high school biology students (N=123). Prior to treatment, students were assessed for cognitive ability and prior knowledge of the analogy vehicle. The analogy-based treatment consisted of teacher…

While many contemporary developmental theorists have avoided taking a stand on the controversial relationship between learning and development, this paper is based on the belief that the notion of "bandwidth of competence," or L. S. Vygotsky's "zone of proximal development," provides a useful framework for considering this…

The ability of tenth grade plane geometry students to structure concepts and relationships from a geometry unit on ratio, proportion and similarity was tested. Analysis of cognitive "maps" of the structural relationships possessed by twenty concrete and twenty formal subjects indicated that formal operational subjects structure subject…

This report evaluates a nursery program for pre K pupils in New York City. The program emphasized oral language, sensory motor coordination, conceptual training and the development of a strong self concept. Fifteen pre K pupils participated in the program. An intake diagnosis was used to help specify areas of deficit which needed attention.…

This article discusses the assessment of language and cognitive development as reflected in preschool activities and describes the Preschool Language-Cognitive Assessment for Curriculum Entry (PLACE). Five task-skill areas associated with common preschool activities (building with blocks, completing puzzles, pounding pegs, etc) are identified. How…

A cross-cultural study undertaken in Morocco was designed to compare the effects of age, schooling and environment on the development of recall and recognition memory. The subjects were 384 males ranging in age from 7 to 2l years. Additional groups of subjects were also studied: Koranic students, Moroccan rug sellers, and American university…

Frequently a variety of visual perception difficulties correlate with reading disabilities. A study was made to investigate the relationship between visual perception and reading disability in families, and to explore the genetic aspects of the relationship. One-hundred twenty-five reading-disabled students, ages 7.5 to 12 years, were matched with…

One aspect of Jean Piaget's theory of cognitive development was tested in this research project. It was hypothesized that an adult individual in the concrete stage of development is able to use seriation and classification in dealing with concrete objects, but is unable to think in terms of possibilities. An individual operating on the formal…

This review of research on the preschool years asserts that a general behavior analysis of those years is essential not only because of its importance as a developmental stage but also because there is a need to fill the knowledge gap between the principles of animal behavior and the principles of practical applications to childhood problems.…
