Authentic and constructive learning experiences that include analysis of primary source documents are necessary elements of effective social studies teaching (Bailyn, 1994; Leinhardt, Stainton, & Virji, 1994; Wineburg & Wilson, 1991; Young & Leinhardt, 1998). This study examines the abilities of 70 fifth and seventh grade students to complete…

This case study of a central office school improvement initiative in an urban school system examines instructional leadership practices of two junior high school principals. The school-based research focuses on correlates of school effectiveness in "low achieving" settings and the principals' capacity to "reflect-in-action," an ability to make…

A study of the correlates of cognitive achievement in Pennsylvania's Educational Quality Assessment Program was conducted by examining both individual (student level) and ecological (building level) correlations. Analyses were completed for grade levels 5, 8 and 11 for the 1985 state assessment. Twenty-four student derived condition variables or…

Systematic changes in their classroom environments occur when students make the transition from upper-elementary to junior high school. Students typically experience a transition from a self-contained classroom to departmentalized instruction in junior high school; they often also experience a transition from heterogeneous to homogeneous,…

Examines the increasing hazardousness of places as a consequence of natural disasters, technological failures, and chronic environmental degradation on a global scale. Describes the trends and impacts of environmental hazards, including their frequency, magnitude and damage on both a regional and international scale. (MJP)

Many would agree that learning on the Web--a highly autonomous learning environment--may be difficult for individuals who lack motivation and self-regulated learning skills. Using a social cognitive view of academic motivation and self-regulation, the objective of the present study was to investigate the relations between students' motivational…

Japanese children's performance in school is a product of a social consensus favoring attention to children's learning, a set of cultural values focusing on the commitment of effort, and a psychological milieu in the family which encourages achievement in a safe and nurturant atmosphere. This paper treats especially this latter environment, that…

Theoretical traditions concerning school environments and student achievement are described, and their insights are linked with analyses of school and classroom interactions to develop a simple conceptual model of environmental influences on student achievement. The literature regarding environmental influences is then reviewed, and the last…

The elderly have generally been portrayed as needy recipients of services; only recently has attention been paid to their contributory role. To explore the nature and characteristics of helping behavior among urban elderly, 117 residents of senior citizens' housing sites in Detroit completed the Altruism Scale for the Elderly and a second measure…

Based on J. E. Grunig's four models of public relations practice (press agent/publicity, public information, and two-way asymmetric and two-way symmetric practice), this paper examines the potential applicability of these models to internal communication systems in organizations. Following an introduction, in which Grunig's models are briefly…

Concepts, tools, and a methodology are needed which will permit the analysis of emergent socio-biospheric problems and facilitate their effective management. Many contemporary problems may be characterized as socio-biospheric; for example, pollution of the seas, acid rain, the growth of cities, and an atmosphere loaded with carcinogens. However,…

Researchers who use the concept of school climate in their research should be aware of the ways in which climate can be measured and what the different methods of measurement imply. Among the typical kinds of measures of school climate currently in use are normative approaches that focus on students' and teachers' perceptions of school norms,…

The role of experience in the developing brain is considered. A categorization scheme based upon the type of information stored and the brain mechanisms involved in storing the information is proposed. Experience-expectant and experience-dependent information storage are differentiated. (BN)

This three-part article introduces a population dynamics model of an information processing system. The first part describes the general model and defines the terms used, the second describes the functional relationships between components, and the third explores the hypothesized emergence of increasingly complex, hierarchical information systems.…

Investigated effects of a year-long home intervention with a sample of preterm infants randomly assigned to one of three groups: developmental intervention, parent/infant intervention, and a no-treatment control. A full-term no-treatment control was also used. Findings confirm earlier studies and demonstrate changes in behavior and behavioral…
