Issues in studying pubertal events are examined, including whether puberty is best characterized as a social construction or a physical event, whether early adolescence is a transitional or distinct life period, life events associated with puberty, boundaries of early adolescence, and possible models for studying pubertal change. (Author/BW)

The issue of whether or not early adolescence is a transitional or stable period of development may be dependent on our ability to describe ways in which early adolescents are quantitatively and qualitatively different from when they were children and how these early adolescent characteristics are forerunners to the more elaborate constructs of…

Reviews the research on (1) developmental stages of play among young children; (2) solitary play as a separate continuum with its own developmental stages; and (3) benefits of solitary play on the child's whole development. (BB)

As a result of discussions at a 1983 Social Science Research Council meeting, a study group was convened to bring together all the professionals currently examining maturation timing. This interdisciplinary group reports findings in two issues of this journal, and its work is introduced in this paper. (LMO)

This paper will present evidence to support ontogenetic and phylogenetic parallels and draw from these comparisons to further illuminate our understanding of micro and macro human development. Individual and collective stages of physical, psychological and spiritual development will be compared and their homologous structures examined.…

Discusses social development stages of middle childhood and peer-group relations, noting demands of group conformity. Presents aspects of cognitive and physical development as well as implications for providing effective guidance and counseling services. (RC)

A questionnaire attempting to define adolescence from the adolescent's view was administered to 300 students, 50 males and 50 females in each of 3 grades (grades 6, 9, and 12). The questionnaire examined (1) ages perceived as dividing points between adolescence, childhood and adulthood; (2) tasks seen as most important in advancing from one period…

Reviews and integrates research on the short-term and long-term impact of different forms of child maltreatment. Notes that scant studies concerning physical and motor development suggest psychobiological consequences of abuse; studies on social and emotional development indicate significant impact of abuse; and studies of cognitive/academic…

The three papers included in this symposium discuss the relevance of Jean Piaget's theory of cognitive development to the early childhood practitioner. First, an overview of Piaget's theory is presented. This focusses on the particular aspects of the theory most relevant to practitioners in early childhood education. Second, curriculum…

The intellectual model of Jean Piaget asserts that individuals pass through a series of various intellectual stages as they mature. Human development is categorized into four basic stages: (1) sensory motor stage, which lasts from birth to about eighteen months; (2) preoperational stage, lasting from eighteen months to about seven years; (3)…

This paper examines the educational philosophy underlying Waldorf Education, focusing on Rudolf Steiner's concept of "vital" or etheric energy and comparing Piaget's and Steiner's stages of cognition. The paper begins with a discussion of school readiness and the trend toward lowering the school entry age, and maintains that this trend…

An understanding of the stages involved in children's development of sensory motor integration would aid in the creation of instructional strategies in physical education. These strategies would optimize both the child's physical coordination and creative development by increasing the correlation between the demands of a learning environment and…

Mental, physical, emotional, and spiritual aspects of midlife males are frequently disturbed and have a definite impact on job satisfaction. Three major tasks to be worked on during this time are described: (1) terminating early adulthood; (2) dealing with polarities; and (3) initiating middle adulthood. (Author)

Describes three perspectives from which middle school teachers can plan laboratory activities for the purpose of improving students' scientific literacy. Perspectives are the learning cycle approach categorizing activities by stages of development; problem-solving skills approach categorizing activities according to the amount of teacher control;…

Reviews current research on infant and toddler physical development, cognitive development, and language acquisition. Provides a list of suggested activities, safety concerns, and opportunities for caregivers to enhance child development. (SD)
