Located within the recently emerged field of researcher development, this article represents an attempt to make a key theoretical contribution to its knowledge base through a conceptual analysis. It presents as propositional knowledge an original theoretical model of the componential structure of researcher development, as interpreted and defined…

Research leadership, a much neglected area of educational leadership and management, is disadvantaged by having an underdeveloped and inadequate knowledge base. This article represents a contribution to this knowledge base through a conceptual analysis. It presents as propositional knowledge an original theoretical model of the componential…

Investigates relationships between family structure variables and 17 measures describing children's intellectual, psychosocial, and physical growth. Subjects were a 10 percent random sample of a Danish cohort consisting of children born in a Copenhagen hospital between September 1959 and December 1961; 857 subjects were followed to age 19.…

A comparison of the theories of Jean Piaget and William Perry (using individual interviews with college students) shows that the two theories outline different and independent processes for assessing intellectual development. (JN)

Based on research studies from fields of education, social organization, and logic, this article argues that the study of organization of knowledge has important implications for students' general intellectual development. Recurring stages of intellectual development are outlined, and implications for improving quality of library school education…

Discusses John Dewey's concept of curriculum, as applied in his Laboratory School. Describes the planning of the school and how its curriculum evolved over time. Identifies both Dewey's belief in educational specialization and his understanding of its limits. Notes the implications of Dewey's work for today's educators. (SG)

Using data from a broader longitudinal study, this investigation explores within-subject and cross-generational stability of intellectual competence and the relationship of such stability to aggressive behavior. Data were gathered three times (when subjects' modal age was 8, 19, and 30 years). Initially, subjects included the entire population…

Defines life-span developmental psychology as the study of constancy and change in behavior throughout the life course. Advances metatheoretical view regarding development. Stresses focus on the dynamic and continuous interplay between growth (gain) and decline (loss). Examines structural contextual factors and study of range of plasticity in…

Estimates confluence model of intellectual development for a within-family sample of 321 children from 101 transracial adoptive families. Mental ages of children and their parents and birth or adoption intervals were used in a nonlinear least-squares estimation procedure to obtain children's predicted mental ages. Results suggest efficiency of the…

Explains that from a prediction standpoint the confluence model is not very efficient. Very modest increments in accuracy are associated with family configuration variables once chronological age is covaried. Suggests that the major postulates of the theory be tested directly, within individuals and with longitudinal data. (Author/AS)

A review of the literature of early adolescence was conducted to provide background information for instructional designers and scriptwriters from the Skills Essential to Learning Project, which develops television/film series and related print materials for different grade levels to enhance the teaching of thinking skills in the context of major…

A review of the literature of middle childhood was conducted to provide background information for instructional designers and scriptwriters from the Skills Essential to Learning Project, which develops television/film series and related print materials for different grade levels to enhance the teaching of thinking skills in the context of major…

An overview of theory and research in memory as it relates to developmental differences is offered in this paper, which is intended to provide background information for the staff of the Skills Essential to Learning Television Project (a multi-level series of video and print resources for classroom use). A model for viewing information processing…

Studied the sleep state organization and EEG patterns at term date in 53 preterm infants as an index of the maturity and integrity of neurophysiological organization that may have implications for their later development. (HOD)

Seventy-one college general biology students were taught a unit in Mendelian genetics by the traditional lecture method. Emphasis was placed on meiotic formation of gametes, dominance, segregation, and independent assortment. The Punnett square model was used for all practice problems. While using this model, students were asked to: (1) identify…
