Implementing the UN Decade of Education for Sustainable Development (DESD): achievements, open questions and strategies for the way forward

This paper looks at the implementation of the DESD from a global perspective. It takes the position that quality education is fundamental for learning how to live sustainably, and that the DESD needs to be better positioned in the education landscape and conceived as a global social movement that must be fostered and nurtured for the well-being of humankind. It suggests that, while there has been progress, much remains to be achieved. Several key challenges are identified. With regard to overcoming these obstacles, it focuses on macro-level strategies that would allow the development of environments in which actions can take root and grow so that the work of the DESD endures beyond the decade itself. Finally, it suggests that there are some opportunities that can be seized to make the task ahead easier to accomplish.     

Showing How Many: young children's written representation of number

Abstract This paper reports a simple experiment which explores young children's written representation of number. Previous research (e.g. Hughes, 1983; Sinclair, Siegrist & Sinclair, 1982) has shown that several factors may influence the extent to which children will spontaneously deploy their knowledge of numerals to represent numerosity, but the available evidence is insufficient to provide a clear account of the relative weight of these factors. The present experiment involved presenting five to six year‐old children with arrays of simple objects and manipulating the wording of the instructions. The results showed that the use of the term ‘how many’ led the vast majority of the children to show numerosity by using materials. In contrast, when asked to represent ‘what’ they could see, most children concerned themselves with depicting the nature of the objects in the array by drawing or writing. These findings suggest that the linguistic context of the task is important in determining the children's representational strategies. Furthermore, it is argued that children's understanding of number and their ability to use numerals is quite separable from their knowledge of when it is appropriate to deploy these skills.     

Numerically restricted food intake in the rat in a free-feeding situation

Rats were trained to leave an array of food after they had consumed a fixed number (three, four, or five) of food items. This discrimination remained in effect despite a shift from 45-mg Noyes pellets to larger and irregularly sized sunflower seeds. The present demonstration replicates work first reported 50 years ago by Otto Koehler and his associates (e.g., Marold, 1939; see also Koehler, 1950), who used avian subjects, and, like those studies, it involved both positive and negative social reinforcement. The present procedure provided a rare instance in which numerical control was exerted over behavior that was primarily consummatory in nature. The results are viewed in terms of the wider literature of numerical competence in animals and are discussed in terms of a numerical process known asprotocounting (Davis & P’erusse, 1988b).     

A perinatal intervention program for urban american indians part 1: design, implementation, and outcomes

High infant mortality rates among American Indians are disproportionate to state statistics for other races and higher than the national average. These findings prompted a community health center in a large Midwestern city to create and provide an American Indian infant mortality reduction project in the early 1990s. Strategies for program implementation included networking with local organizations, communicating with reservation health clinics throughout the state, educating American Indian mothers and their community about factors contributing to American Indian infant mortality, and providing individual case management to American Indian women and infants. We offer this article for three reasons: This grant project was successful, disparity in rates of infant mortality among peoples of color continues, and a paucity of information exists about the health behaviors of American Indian women.     

Investigation of functional literacy and job-skills used in clerical workplace settings

This paper presents the findings of a study on the functional literacy and job-skills used by clerical workers in a variety of work situations. The study focused on the employees' own perceptions of their tasks. The results revealed three main requirements for successful performance of clerical work: (1) the possession of requisite knowledge and the ability to apply it; (2) thinking skills; (3) the ability to manage oneself and others. None of these capacities was sufficient on its own. The authors argue that the study has important implications for vocational education and training and for easing the transition from school to work.

Zusammenfassung Dieser Artikel präsentiert die Ergebnisse einer Studie über funktionale Alphabetisierung und Berufskenntnisse, die Büroangestellte in unterschiedlichen Arbeitssituationen benötigen. Die Studie konzentriert sich auf die eigenen Wahrnehmungen der Angestellten ihrer Aufgaben. Drei Hauptanforderungen für eine erfolgreiche Bewältigung der Büroarbeit wurden identifiziert: 1. fundiertes Wissen und die Fähigkeit zur Anwendung, 2. die Fähigkeit, mitzudenken, 3. die Fähigkeit, sich selbst und andere zu organisieren. Keine dieser Kapazitäten ist ohne die anderen ausreichend. Der Autorinnen argumentieren, daß diese Studie sich wesentlich auf Berufsbildung und Fortbildung auswirken und den Übergang von der Schule zum Arbeitsplatz erleichtern kann.

Resumen El trabajo presenta los resultados de un estudio realizado sobre la capacidad funcional de leer y escribir y sobre las habilidades laborales aplicadas por empleados en una variedad de situaciones de trabajo. El estudio se concentraba en las propias percepciones de los empleados en cuanto a sus cometidos. Los resultados revelaron tres principales requisitos para el desempeño exitoso del trabajo de oficina: (1) la posesión de los conocimientos requeridos y la capacidad de aplicarlos; (2) habilidades intelectuales; (3) la capacidad de gestionarse a sí mismo y a los demás. Ninguna de estas capacidades era suficiente por sí misma. El autor sostiene que el estudio tiene consecuencias importantes para la educación y la formación vocacional y para facilitar la transición del colegio al trabajo.

Child abuse treated in a psychiatric day hospital

Actuarial, medical and social data are reported on 50 psychiatric day hospital patients known to have abused their children and 50 non-abusers undergoing treatment at the same time. A sub-group of 30 of each completed personality and intelligence tests and the majority had electroencephalograms, and these results were compared with those of a group of 30 healthy mothers selected by health visitors for positive child-rearing abilities.Findings which confirms those of other studies of child abuse include youthfulness, a higher incidence of family violence from childhood onwards, more unplanned pregnancies and lower intelligence in the index group. In this sample, however, all social classes were represented, there was no significant differences in perinatal pathology between the groups, personality scored showed high morbidity in the patient groups but few distinctive features, and EEGs were not significantly more abnormal in the index group than in the two contrast groups. Moreover, the index group did not show the expected discrepancy between verbal and performance sub-tests on the Wechsler Adult Intelligence Scale.Treatment of the 50 child-abusers with their children resulted in a re-injury rate of 8% during the four year period of study. A scheme for early identification and prevention is outlined.     

Structuring Occasions

Within the mathematics education literature, the term constructivism has been subject to a diversity of interpretations, many of which are trivializations of original theoretical work. We suggest that trivialized versions of constructivism continue to be promulgated due, in large part,to misunderstandings of some of the vocabulary adopted by its advocates. This situation has been the source of considerable frustration in our ongoing efforts to communicate the insights and implications of radical and social constructivist theories to preservice and practicing teachers. We discuss some of the specifics of these frustrations along with strategies intended to flag and circumvent them in our work with teachers. The writing is structured around a set of recursively elaborated interpretations of a classroom episode. Developed around varied understandings of the terms structure and construct, these interpretations are intended to show how we have worked with teachers to foster a deep appreciation of how learning might be reframed as dependent on, rather than determined by, teaching.This revised version was published online in September 2005 with corrections to the Cover Date.     

Pathways to Undergraduate Research Experiences: a Multi-Institutional Study

The positive impact of undergraduate research experiences on students’ post-secondary success is well-documented. However, these conclusions are drawn from undergraduate students who already participate; very little research has explored the pathways by which students enter these experiences. Using data from a multi-institutional survey, we examined students’ reasons for participating and differences across institutions and demographic groups. Overall, students cited social and experiential reasons as key motivators for participation and a perceived lack of research readiness as a key barrier. Differences were also found across academic year. Implications from this study address issues of access, preparation, and institutional policies around undergraduate research.     

Measuring Habituation in Infants: An Approach Using Regression Analysis

The effectiveness of different habituation criteria was examined by means of computer simulations. A criterion based on fitting a second-order polynomial regression function to the looking time data was described. This criterion produced more accurate estimation of looking times as well as higher experimental power for detecting novelty effects, compared to the traditional windowed running average criterion or to a criterion based on linear regression. The polynomial regression approach probably has this advantage because it utilizes all of the available looking time data, rather than just the data in the current windowed average, and because it is sensitive to nonlinear trends in looking time. This new habituation criterion is easy to implement on a laboratory computer, and it should increase session lengths by no more than one trial or so, compared to windowed average criteria. With regard to test-retest reliability, all of the habituation criteria that were evaluated appear to have low reliability on average, with high sample-to-sample variability. These undesirable reliability characteristics are attributable to the high variability of infants' attentional behavior.     

College Student Wellness: A Comparison Between Traditional‐ and Nontraditional‐Age Students

This study examined differences in wellness reported by traditional‐ and nontraditional‐age students as measured by the Wellness Evaluation of Lifestyle (J. E. Myers, T. J. Sweeney, & J. M. Witmer, 1998). Differences were found between the 2 age groups on 4 self‐regulation dimensions: realistic beliefs, sense of control, exercise, and self‐care. Implications for counseling practice and suggestions for future research are discussed.
