Interpreting and creating computational systems models is an important goal of science education. One aspect of computational systems modeling that is supported by modeling, systems thinking, and computational thinking literature is "testing, evaluating, and debugging models." Through testing and debugging, students can identify aspects…

Bronfenbrenner's (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children's aggression via analyses of 3 waves of data (1 wave…

Because person-organization fit relates to important outcomes, and because fit is a time-dependent process, there exists a need to model longitudinal data related to fit. In a multi-university sample (N=1174), we tested hypotheses concerning person-organization fit and various behavioral and attitudinal outcomes; correlations between changes in…

The attention deficit hyperactivity disorder (ADHD) symptom presentation of young adolescents with ADHD was examined in association with the transition to middle school. This study used data collected in the Multimodal Treatment Study of ADHD, which included children between 7 and 9 years of age with a diagnosis of ADHD (n = 258) and grade- and…

Summarizes a study that tested a theoretical model concerning elementary and secondary school principals' influence on student achievement. Results showed that 3 latent instructional leadership variables (school governance, instructional organization, and school climate) affected student achievement. Includes 54 references. (MLH)

Modern psychological theory implies that behavior and neural function are correlated. Models of the operation of the nervous system can be used to predict and explain behavioral events. The purposes of this paper are to briefly outline a model at the biopsychological level that leads to predictions about the retention of verbal material, to show…

A theoretical framework for mapping school political life is developed which distinguishes elite, bureaucratic, coalitional, and participant types of school political organizations. The framework provides tools for analyzing and comparing patterns of political behavior within and across school political behavior settings. Definitions and…
