“We are only looking for the right answers”: the challenges of controversial issue instruction in South Korea

This study explores the perceptions of South Korean moral and social studies education teachers, teacher educators, and students on the promises and challenges of introducing and discussing controversial issues within their classrooms. The findings suggest that college entrance exams, textbooks, didacticism, dualism, administrators, textbooks, standards, fear of bias, scant instructional time, and reticent classroom climates collectively undermine controversial instruction in South Korea The few pathways that counter these challenges include student-generated curriculum topics and tying lessons to current events. Similar to other democratic societies, South Korea's paucity of reflective thinking on controversial issues represents a clear hazard to the development of citizens who make informed and reasoned decisions for the common good.

Determinants of Disciplinary Practices in Low-Income Black Mothers

Disciplinary attitudes and practices of low-income black mothers were examined. Mothers were interviewed about their parenting attitudes and control practices, and their responses were coded in terms of the degree to which they took a parent- versus a child-oriented approach to discipline. Mothers in the sample varied widely in their attitudes toward physical punishment, and mothers who used power-assertive techniques were as likely to take the child's perspective and give input into the socialization process as those who did not. Factors associated with maternal disciplinary styles included: maternal education, father absence, maternal age, and self-reported religious beliefs. Findings are discussed in terms of the variability in disciplinary practices in this population, as well as the factors contributing to these individual differences.     

Encouraging versatile thinking in algebra using the computer

In this article we formulate and analyse some of the obstacles to understanding the notion of a variable, and the use and meaning of algebraic notation, and report empirical evidence to support the hypothesis that an approach using the computer will be more successful in overcoming these obstacles. The computer approach is formulated within a wider framework ofversatile thinking in which global, holistic processing complements local, sequential processing. This is done through a combination of programming in BASIC, physical activities which simulate computer storage and manipulation of variables, and specific software which evaluates expressions in standard mathematical notation. The software is designed to enable the user to explore examples and non-examples of a concept, in this case equivalent and non-equivalent expressions. We call such a piece of software ageneric organizer because if offers examples and non-examples which may be seen not just in specific terms, but as typical, or generic, examples of the algebraic processes, assisting the pupil in the difficult task of abstracting the more general concept which they represent. Empirical evidence from several related studies shows that such an approach significantly improves the understanding of higher order concepts in algebra, and that any initial loss in manipulative facility through lack of practice is more than made up at a later stage.     

Beyond Standard Models—Meeting the Challenge of Modelling

This paper reports on a project that incorporated mathematical modelling within a pre-university subject at a secondary college. The program emphasised modelling rather than models and extended over two years. A qualitative methodology was used to evaluate the program with information collected in a variety of forms including student written reports, oral interviews, video reports, diaries, questionnaire data, as well as informal observation. The program was evaluated in terms of five criteria derived from the stated aims. Erom the synthesis and triangulation of the data it was inferred that the program aims were achieved to an encouraging degree. The paper describes and illustrates key aspects of the program and its evaluation.

The study of stress and competence in children: a building block for developmental psychopathology

This article discusses the building blocks for a developmental psychopathology, focusing on studies of risk, competence, and protective factors. The current Project Competence studies of stress and competence are described, with particular attention to the methodology and strategies for data analysis. The authors present a 3-model approach to stress resistance in a multivariate regression framework: the compensatory, challenge, and protective factor models. These models are illustrated by selected data. In the concluding section, an evaluation of the project is offered in terms of future directions for research.
