Youth suicidal behavior is a significant public health problem, and schools can play an important role in youth suicide prevention. However, schools cannot do this alone; they need the student's family members and peers, and other professionals and community members, to do their part. School personnel, and particularly school-employed mental…

In this article, the authors examine the conceptualization and measurement of ethnic identity as a multidimensional, dynamic construct that develops over time through a process of exploration and commitment. The authors discuss the components of ethnic identity that have been studied and the theoretical background for a developmental model of…

The authors propose a simple behavioral economic model (BEM) describing how reinforcement and interval timing interact. The model assumes a Weber-law-compliant logarithmic representation of time. Associated with each represented time value are the payoffs that have been obtained for each possible response. At a given real time, the response with…

Over the past several decades, research has focused increasingly on developmental precursors to psychological disorders that were previously assumed to emerge only in adulthood. This change in focus follows from the recognition that complex transactions between biological vulnerabilities and psychosocial risk factors shape emotional and behavioral…

A new transform proposed by Oyelami and Ale for impulsive systems is applied to an impulsive fish-hyacinth model. A biological policy regarding the growth of the fish and the hyacinth populations is formulated.

The concept of error detection plays a central role in theories of executive control. In this article, the authors present a mechanism that can rapidly detect errors in speeded response time tasks. This error monitor assigns values to the output of cognitive processes involved in stimulus categorization and response generation and detects errors…

Delay of Gratification (DG) and Delay Discounting (DD) represent two indices of impulsive behavior often treated as though they represent equivalent or the same underlying processes. However, there are key differences between DG and DD procedures, and between certain research findings with each procedure, that suggest they are not equivalent. In…

The Early Childhood Program in the Department of Curriculum, Instruction and Administration at Tuskegee University (Alabama) is described as a convergence of Jean Piaget's constructivism and John Dewey's progressivism. It is designed to provide preservice teachers with experiences that promote reflective practice and that view the learner as an…

This 42-month project at the University of Denver (Colorado) developed materials and faculty development activities concerning application of Kitchener and King's reflective judgment theory. Testing and implementation were at the University of Denver and Bowling Green State University (Ohio) and the University of Missouri (Columbia). The model…

This paper discusses portfolios as an evaluative process in teacher education, noting that although there has been significant curriculum change over the years, yet little change has occurred in student evaluation methods. For schools to demonstrate improvement, new and creative evaluation measures are needed. Portfolios provide a chance to create…

The Department of Educational Foundations at Western Illinois University developed a model preservice curriculum to respond to the problem of preparing teachers who can influence their environment rather than be victims of it and who can effectively transmit that message to students. Entitled Empowerment through Cognitive and Social Management…

The Ohio Consortium for Portfolio Development was established in 1988 as an interinstitutional research effort to integrate portfolio development into teacher education. A subphase focused on portfolio use by entry year teachers in a metropolitan school system. Personnel at Wright State University, Central State University, and the University of…
