Describes the stages of the change process when redesigning an education system: (1) initiating the process, (2) designing the new system, (3) planning the implementation, and (4) implementing the design. The common obstacles encountered during the change process (derived from a survey of 60 schools nationwide) are analyzed, and the status of each…

In this longitudinal study, changes in parental labelling and infants' categorization skills were examined as potential predictors of vocabulary acquisition, the age of the naming explosion, and the acquisition of subordinate labels. Findings suggest that the influence of each factor varies as a function of the stage and aspect of lexical…

Introduces the essential constructs involved in dynamic modeling, in relation to issues in psychological development. Presents several instances of how the principles of dynamic systems can be translated into mathematical formalism. Concludes that transition is a key invariance in development and that single subject, longitudinal designs are…

Usher syndrome, Type I, requires multiple adaptations throughout the life cycle because each stage of life has tasks and losses associated with deafness and progressive retinitis pigmentosa. This article examines the issues raised at each stage, using clinical vignettes from persons who have this condition and their families. (Author/DB)

Evaluates the role of age on the rate of acquiring English as a second language in an immersion setting in children with native languages typologically very different from English. Results suggest that on certain aspects of grammar, different-aged children can acquire a second language during the first three years of acquisition at similar rates…

Analyzes attachment theory's viability as an overarching framework for counseling psychology. Places particular emphasis on the integrative potential and heuristic value of the theory, arguing that it can use biological (structural), psychological (cognitive/affective), and social dimensions of experience to clarify developmental dynamics in…

Reviews research related to humor, especially the role humor can play in the instructional process. Highlights include theories of humor; variables associated with humor; health benefits derived from humor; developmental stages and humor; effects of humor in children's educational television; and humor in the college environment. (25 references)…

Discusses difficulties of examining Jean Piaget's work, caused in part by his own revisions and earlier, inadequate interpretation in English translation. Examines common misunderstandings of Piagetian developmental stages and similar misinterpretations of his ideas on education. Focuses on importance of other disciplines, including psychology and…

Examined free recall of kindergartners and third and eighth graders. The use of organizational strategies, which was demonstrated by third and eight graders, led to increased performance only for eighth graders. These results suggest a phase in strategy development when production of a strategy results in little benefit in performance. (LB)

Bayley's major contributions to developmental psychology are reviewed. These include her concern with measurement and methodology and her early anticipation of such topics as behavior genetics. Her work in such areas as androgyny and body build, motor and mental development, and maternal and child behaviors is summarized. (LB)

First, second, and third graders (n=33) were observed in classrooms during a three-year study of the development of private speech and its relationship to behavioral accompaniment to task, attention, and task performance. Findings agreed with Vygotskian predictions that private speech promotes effective task-related behavior. (SH)

The article discusses ways to make mathematics instruction with learning-disabled and other children more developmentally appropriate by building on children's informal understandings in active purposeful learning, using less direct instruction and paper-and-pencil work. Ideas are applied to the teaching of fractions. Instructional materials are…

Examines Piaget's theory of disequilibration as the tension and subsequent growth caused when new information must be assimilated or accommodated to fit one's view of reality. Indicates ways Christian religious educators can use the concept of disequilibration to understand adolescents' emotional and cognitive growth. Suggests implications for…

Describes the interdisciplinary research of Myrtle B. McGraw; examines the controversy about McGraw's concept of critical period; and assesses her impact on current research. McGraw contended that the overlapping phases involved in neuromuscular integration demonstrate that learning and maturation interact during development. (BC)

Review of literature concerning problem solving in genetics and Piagetian stage theory. Authors conclude the research suggests that formal-operational thought is not strictly required for the solution of the majority of classical genetics problems; however, some genetic concepts are difficult for concrete operational students to understand.…
