This study describes a classroom action research activity regarding a group of elementary school teacher candidates' perceptions of good mathematics problems. A questionnaire containing 20 problems was given, and the candidates were asked to rate the quality of each problem on a 5-point scale. The results revealed that the majority of the teacher…

Over the past two decades, calculus reformers have called for the use of alternative pedagogical techniques to promote student learning. Some mathematics instructors have responded by developing a set of student projects intended to hone thinking skills and improve the mathematical writing skills of calculus students. Drawbacks to this strategy…

Problem-solving discussions were observed within families of children with mental retardation and multiple comparison groups (total N = 162 families). As expected, parents were more persistent and directive with their children who had mental retardation, but they also avoided negative exchanges with these children. These patterns did not spillover…

School discipline is a growing concern in the United States. Educators frequently are faced with discipline problems ranging from infrequent but extreme problems (e.g., shootings) to less severe problems that occur at high frequency (e.g., bullying, insubordination, tardiness, and fighting). Unfortunately, teachers report feeling ill prepared to…

Mathematical modeling is explored as both problem posing and problem solving from two perspectives, that of the child and the teacher. Mathematical modeling provides rich learning experiences for elementary school children and their teachers.

This document concerns the problem of violent youth gangs, noting that gang activity is no longer restricted to the depressed urban centers but is arriving in suburbs and edge cities. This paper discusses who is in gangs, what gangs offer their members, positive prevention and intervention approaches, and approaches to avoid. The suggested…

Because research has determined that specific management techniques can have an effect on the classroom behavior of students, an observational rating scale was developed to assess the type of management techniques six elementary teachers in a program for behaviorally disordered children used to control behavior. Correlational analyses were used to…

Opposing viewpoints by two physicians are presented on the controversial issue of National Health Insurance. (JR)

The problems, unintended consequences, and successes of the 1965 Immigration and Nationality Act are discussed and analyzed. (EH)

The general use of the Spearman-Brown formula for calculating the reliability of parallel tests with different lengths is reviewed. The importance of the assumption that the component tests be parallel is noted and the property that parallel tests must be non-negatively correlated is derived. (Author)

The person with a borderline personality is considered to be neither neurotic nor psychotic, but to exist somewhere in between these two diagnostic categories. Psychoanalytic theorists who have researched the phenomenon of the borderline personality have shifted their emphasis away from Freud's instinct psychology and toward an ego psychology…
