This article investigates legal and political issues as they relate to school vouchers serving students of color. Specifically, we draw on the empirical, historical, and legal research to examine whether school vouchers will create a more equitable system of education for poor students of color. First, we present a history of vouchers, including how they were used to support segregation. We then discuss how vouchers as a broad opportunity for educational equity for poor children (of color) might present particular challenges in light of, first, the race-neutral approach in contemporary case law and state statutes and, second, the relatively small percentage of U.S. children taking advantage of such programs. Finally, we present empirical results regarding African American families’ support and use of vouchers and a discussion of the racial politics of school vouchers. We argue that unless voucher programs and proponents address race directly, operate on a larger scale, and attend to the broader social justice issues facing urban communities, it will be difficult for such policies to support the greater good for African American children or society as a whole.  相似文献

The phenomenon of women engaging in entrepreneurship is expanding and becoming acknowledged as a valuable resource that must be institutionally and socially supported. Through entrepreneurship education, female students, as potential entrepreneurs, can develop and strengthen those skills and behaviours identified as characteristic of successful entrepreneurs. This paper explores four attributes associated with entrepreneurship (creativity, problem management, risk management, and self-confidence) of 1838 undergraduate students from 11 universities in Latin America (Mexico, Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, and Uruguay) and one in Spain, used as a control group. By comparing the results for the male and female student population, self-confidence appears as an attribute that is present at the same level in both groups; statistically significant differences were reported for the other three attributes (creativity, problem management, and risk management). Entrepreneurship programmes can utilise such information to strengthen in female students those attributes for successful engagement in entrepreneurial activity.  相似文献

The effects of witnessing community violence on aggressive cognitions and behavior were investigated in an ethnically diverse sample of 4,458 children living in urban neighborhoods. Prior violence exposure had a significant effect in increasing aggression, normative beliefs about aggression, and aggressive fantasy. Although exposure to violence predicted aggressive behavior both in Grades 1 through 3 (ages 5-8) and Grades 4 through 6 (ages 9-12), the effects on social cognition were only evident in the later grades. Furthermore, the effect of violence exposure on aggression in the later grades was partially mediated by its effect on social cognition. These findings suggest that witnessing community violence has an effect on children's aggressive behavior through both imitation of violence and the development of associated cognitions as children get older.  相似文献

This qualitative study highlighted student perspectives on barriers to success at a community college located in a south Texas city. The study examined barriers to student success, the knowledge that successful students possess to overcome the barriers, and the actions that successful students undertake to overcome the barriers. Padilla's (2004 Padilla , R. V. ( 1999 ). College student retention: Focus on success . Journal of College Student Retention , 1 ( 2 ), 131145 .[Crossref] [Google Scholar]) theoretical framework and methods for modeling student success provided the conceptual framework for the study. The data analysis resulted in the development of a local student success model and an implementation model for student services at the subject campus.  相似文献

Abstract

Drug abuse by adolescents has been investigated in various surveys that reported correlations between age, gender, and activity. However, none of these studies included chemical analyses to help substantiate the statements of participants. In the present study, the urine specimens of 964 students (439 females, 525 males; mean age 22.1 years, s = 1.7), who applied to study sports sciences at university, were assessed for anabolic steroids, stimulants, and selected drugs prohibited in sports. In total, 11.2% of the urine specimens provided contained drugs covered by doping controls. The most frequently detected compound was the major metabolite of tetrahydrocannabinol (9.8%) followed by various stimulants related to amphetamine and cocaine (1.0%). Indications of anabolic steroid use were found in 0.4% of urine samples but originated from contraceptives containing norethisterone. The present study provided unambiguous data on the status quo of drug (ab)use by adolescents hoping for a career related to elite sport or sports sciences. No use of anabolic steroids was detected. However, evidence for stimulants and tetrahydrocannabinol administration was obtained, although not reported by any participant, which highlights the issue of under-reporting in surveys based solely on questionnaires.  相似文献

In a context of morphological expansion of the general population, how do athletes follow such a pattern of anthropometric growth? Is there any relation to performance? Biometric data including mass, height, body mass index (BMI) and age were collected for 50,376 American athletes representing 249,336 annual performers playing in professional baseball, football, ice hockey and basketball. Distributions by mass in National Football League (NFL) players are described by periods. Field goals have been studied in relation to players’ height in the National Basketball Association (NBA). Between 1871 and 2011, athletes from the four sports have increased significantly in mass, height and BMI, following a multi-exponential function series. Consequently, biometric differences between athletes and the general population are increasing gradually. Changes in the mass distribution within the NFL show the emergence of a biometrical specificity in relation to the field position. At the professional level, performance remains structured around precise biometric values. In the NBA, a height-attractor at 201.3 ± 6.3 cm for the best scorers is invariant, regardless of the level of play. These results suggest that laws of growth and biometrics drive high-level sport and organise performance around the specific constraint of each field position. Discrepancies between some mass and height developments question the (disproportionate) large mass increase (relative to the height increase) during the 1980s and 1990s.  相似文献

The Latvian Education Informatization System LIIS project covers the whole information grid: education content, management, information services, infrastructure and user training at several levels – schools, school boards and Ministry of Education and Science. Informatization is the maintained process of creating the technical, economical and social conditions for fulfilment of information needs. The initiative started in 1997. The strategy for education content creation for 2001–2004 is to cover all forms of cognition – rational, empirical, emotional and modelling – and several levels of skills for all levels of education. The Current LIIS results as at 2002 have been that: developed teaching aids are being used (workbooks, interactive software, tests etc) (approx. 20% of the total amount of high school programme can be taught using information and communication technologies); about 1000 sites are using LIIS school management software; 66% of all teachers are trained on ICT usage; 97% of schools have dial‐up connection to the Internet in year 2002 (44% have a permanent connection); and the number of pupils per computer has decreased from 67 (year 1997) to 20 (year 2002).

Le système d'information LIIS dans l'éducation en Lithuanie

Le projet du système LIIS du système information pour l'éducation comme toute la grile: contenu de l'éducation, management, services d'information, infrastructure et fomation des utilisateurs à divers niveaux: écoles, administrtion des écoles, Ministerie de l'Education et de la Science. Ce projet a débuté en 1997. La stratégie pour créer un contenue de l'éducation 2001–2004 doit couvrir toutes les formes de la connaissance traditionnelle, ainsi que émotionelle, proposant des modèles et divers niveaux de compétences pour tous les niveaux d'éducation. Les résultats actuels du LIIS ont été en 2002: Les moyens d'enseignement dévelpppés sont utilisés (livres, software interactif, tests, etc.) (approximaticement 20% du programme total des programmes des écoles seconfaires peuvent être enseignés en utilisant les technologies de l'information); environ 1000 titres utilisant ler software de management des écoles; 66% des maîtres ont été formé à l'emploi de TIC; 97 % des écoles ont été connectés à Internet en 2002 (44% de connection permanente); et le nombre d'élèves par ordinateur a diminué de 67 (en 1997) à 20 (en 2002)

Das lettisches Bildungsinformationssystem LIIS

Das lettische Bildungsinformationssystem, das LIIS – Projekt, umfasst das gesamte Informationsraster: Bildungsinhalt, Management, Informationsdienste, Infrastruktur sowie Nutzerausbildung auf mehreren Ebenen – Schulen, Schulkommissionen und Bildungsministerien. Die Initiative begann in 1997. Das Konzept für die Erfassung von Bildungsinhalten für 2001–2004 ist, alle Formen des Zugangs – rational, empirisch, emotional, modellierend – und mehrere Stufen von Fertigkeiten für alle Bildungsniveaus zu berücksichtigen. Das gegenwärtige Stand von LIIS (2002) ist: schon entwickelte Lehrhilfen werden benutzt (Workbooks, interaktive Software, Tests usw.) (Ca. 20% des gesamten Highschool‐Programms kann mit Hilfe von Informationstechnologie gelehrt werden); an rund 1000 Standorten wird LIS Schulmanagement‐Software genutzt; 66% aller Lehrer wurden in die Verwendung von ICT eingeführt; 97% aller Schulen haben im Jahr 2002 Wählverbindung in das Internet (36%: permanente Verbindung); die Anzahl von Schülern pro Computer hat von 67 (Jahr 1997) auf 25 (Jahr 2002) abgenommen.  相似文献

Research has identified factors associated with academic success by evaluating relations among psychological and academic variables, although few studies have examined theoretical models to understand the complex links. This study used structural equation modeling to investigate whether the relation between test anxiety and final course grades was mediated by personal control, self-efficacy, goal orientation, coping strategies, and self-regulation. Participants were 297 undergraduate students taking an algebra course designed for engineering students. Results indicated that the proposed theoretical model was supported by the data, although a modified model produced a better fit. Other competing models were also tested. Collectively, analyses revealed that the psychological variables played important roles in predicting students’ grades, as all the structural coefficients and R 2 statistics were statistically and practically significant. Findings suggest value in the development and testing of additional models that contribute to the expansion of intervention programs to enhance academic outcomes among students.  相似文献
