Exercising older people´s brains in Costa Rica: Design principles for using information and communication technologies for cognitive activity and social interaction     

María Dolores Castro Rojas  Ann Bygholm  Tia G.B Hansen 《Educational gerontology》2018,44(2-3):171-185

This study is part of a design-based research project aimed at designing a learning intervention for enabling Costa Rican older people to use information and communication technologies for cognitive activity and social interaction. Data from relevant literature, a focus group with older adults, and interviews with professionals teaching older adults how to use information and communication technologies were analyzed, in order to create context-sensitive design principles that could guide the design of learning interventions that meet the needs of older learners. The analysis derived context-sensitive design principles that include wider topics that influence the learning process, such as emotions and stereotypes related to learning about and using information and communication technologies, as well as the social support to that learning. The resulting eight design principles argue for respectful learning environments, in-depth comprehension of changes related to aging, time and space to reflect on emotions related to the learning process, and acknowledgment of participants’ individuality.  相似文献   

Apprenticeship — The perilous journey from Germany to Togo     

Ken Kempner  Claudio de moura Castro  Daniel Bas 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1993,39(5):373-390

This paper explores the economic and cultural reasons why apprenticeship programmes imported by developing countries typically fail. The authors pursue this inquiry in a comparative manner by addressing experiences in Western Africa and by drawing on the outcomes of apprentice programmes in some industrialised countries. The authors identify major issues that explain why programmes borrowed from the West are so ineffective in Africa. Essentially, the imported apprenticeship programmes are decidedly Western and white concepts that link education to employment through certification and individual ownership of knowledge, and that clash with African cultural traditions. Individual success is central to Western-based programmes, which is opposed to more community-based conceptions of traditional African culture. Because of this inherent mismatch, the authors conclude with several options for developing apprenticeship training in Africa that are more relevant and adaptable to the prevailing cultural, educational and economic climate. They encourage programmes that improve the educational system incrementally and caution against programmes that run counter to the predominant culture.

Zusammenfassung In diesem Artikel werden die wirtschaftlichen und kulturellen Gründe untersucht, warum die von Entwicklungsländern importierten Ausbildungs-programme typischerweise erfolglos bleiben. Die Autoren gehen dieser Frage nach durch Vergleiche von Erfahrungen in Westafrika mit Ergebnissen von Ausbildungsprogrammen in einigen Industrieländern. Die Autoren zeigen die wesentlichen Merkmale auf, aus denen ersichtlich wird, warum vom Westen entliehene Ausbildungsprogramme in Afrika so wenig Wirkung zeigen. Hauptsächlich handelt es sich bei den importierten Ausbildungsprogrammen um auf den Westen und auf Weiße zugeschnittene Konzepte, die Bildung und Arbeitsplatz mittels Zeugnissen und individuellem Wissen miteinander verbinden und mit afrikanischen Kulturtraditionen nicht in Einklang zu bringen sind. Individueller Erfolg ist Kernpunkt westlicher Programme, die den eher gemeinschaftsbezogenen Konzeptionen traditioneller afrikanischer Kultur entgegenstehen. Wegen dieses naturgegebenen Mißverhältnisses zeigen die Autoren abschließend mehrere Möglichkeiten zur Entwicklung von Ausbildungsprogrammen für Afrika auf, die den kulturellen, erzieherischen und wirtschaftlichen Gegebenheiten in Afrika besser angepaßt sind. Sie befürworten Programme zu einer stetigen Verbesserung des Bildungssystems und warnen vor Programmen, die der prädominanten Kultur entgegenwirken.

Résumé Le présent article cherche les raisons économiques et culturelles pour lesquelles les programmes d'apprentissage importés par les pays en développement échouent généralement. Les auteurs poursuivent leur recherche d'une manière comparée en examinant les expériences faites en Afrique occidentale et en exploitant les résultats des programmes de ce genre appliqués dans certains pays industrialisés. Les auteurs définissent les problèmes majeurs qui expliquent pourquoi les programmes empruntés au monde occidental sont si peu efficaces en Afrique. Avant tout, les programmes d'apprentissage sont typiquement occidentaux, les concepts blancs lient l'éducation à l'emploi grâce à un système de certificats, et la propriété individuelle du savoir est en désaccord avec les traditions culturelles africaines. Le succès individuel qui est central dans les programmes appliqués en Occident est opposé aux conceptions davantage fondées sur la collectivité de la culture africaine traditionnelle. En raison de ce défaut d'adaptation inhérent, les auteurs concluent en proposant plusieurs options de développement de l'apprentissage professionnel en Afrique qui sont plus pertinentes et adaptables au climat culturel, éducatif et économique qui prévaut dans cette région. Ils prônent des programmes visant à améliorer progressivement le système éducatif et mettent en garde contre ceux qui vont à l'encontre de la culture prédominante.

Using Deakin University as an example, the author traces the adoption of optical disk technology in Australia; reports and comments on the recent technical development; and suggests some potential applications. She reviews critically the slow progress made in Deakin on multimedia research and proposes that proper development opportunities and facilities must be given to help staff understand and use educational technology.  相似文献   

Peer perceptions of hyperactivity and medication effects     

C K Whalen  B Henker  J Castro  D Granger 《Child development》1987,58(3):816-828

This study focused on peer sensitivity to differences in social behaviors between hyperactive and normal comparison peers and, especially, to medication-related behavioral differences. In Study 1, normal sixth graders rated videotapes of normal and hyperactive boys playing a social interaction game. Half of the hyperactive boys were taking methylphenidate, and the other half placebo. In Study 2, fourth- and sixth-grade children rated a different sample of hyperactive boys (seen on both methylphenidate and placebo) playing the same interaction game. Hyperactive boys taking placebo were perceived as exhibiting more externalizing problem behaviors than either medicated hyperactive boys or comparison boys. The medication effects were robust, spanning many behavioral domains and emerging consistently across the 2 studies. There were few grade or gender differences. Discussion focused on children's detection of treatment-related differences in the social behaviors of their peers, as well as on the imperfect relation between social behavior and social standing.  相似文献   

The World Bank Policies: Damned if you do,damned if you don't     

Claudio De Moura Castro 《比较教育学》2002,38(4):387-399

To some, the World Bank is the all-powerful arm of imperialism. Others regret that it is powerless, incapable of influencing policies in the countries in which it operates. This paper discusses these issues, as seen by the author, a former employee both of the World Bank and the Inter-American Development Bank, as well as a civil servant and consultant at the receiving end of the loans. This experience provides an inside view but the reader has to be warned of the biases that might have resulted from it.  相似文献   

Genetic Moderation of Intervention Efficacy: Dopaminergic Genes,The Incredible Years,and Externalizing Behavior in Children          下载免费PDF全文

This study investigated whether children scoring higher on a polygenic plasticity index based on five dopaminergic genes (DRD4, DRD2, DAT1, MAOA, and COMT) benefited the most from the Incredible Years (IY) parent program. Data were used from a randomized controlled trial including 341 Dutch families with 4‐ to 8‐year‐old children (55.7% boys) showing moderate to high levels of problem behavior. IY proved to be most effective in decreasing parent‐reported (but not observed) externalizing behavior in boys (but not girls) carrying more rather than fewer dopaminergic plasticity alleles; this Gene × Intervention effect was most pronounced in the case of boys whose parents’ manifested the most positive change in parenting in response to the intervention. These results proved robust across a variety of sampling specifications (e.g., intention to treat, ethnicity).  相似文献

“Won’t You Be My Neighbor?”: Intergenerational Dialogics in Mister Rogers’ Neighborhood Viewer Mail     

Alexandra Castro Klarén 《Communication quarterly》2017,65(1):60-79

From the opening of each Mister Rogers’ Neighborhood (MRN) program, Fred Rogers invites his viewers to converse with him. MRN viewer letters demonstrate the efficacy of this call in the familiar and conversational manner in which viewers address the program’s host. This article examines a sample of these letters from the perspective of Mikhail Bakhtin’s dialogical theorization of the conversational moment—a moment that “provokes an answer, anticipates it, and structures itself in the answer’s direction.” Along with Bakhtin, the dialogical perspectives of Roger Burggraeve, Paulo Freire, and Martin Buber are examined and applied to further elucidate the communication ethics at work in the lettered correspondence and on the television program. MRN viewer letters reveal a remarkable consistency in their thematic quality and constitute a field of study about the dialogical relationship between Rogers and his audience.  相似文献   

Associations of total sedentary time,screen time and non-screen sedentary time with adiposity and physical fitness in youth: the mediating effect of physical activity     

Verónica Cabanas-Sánchez  David Martínez-Gómez  Irene Esteban-Cornejo  Alejandro Pérez-Bey  José Castro Piñero  Oscar L. Veiga 《Journal of sports sciences》2019,37(8):839-849

The aims of the present study were: i) to examine the associations of total accelerometer-based sedentary time (ST) and specific-domain self-reported ST (i.e., screen-based, educational-based, social-based, and other-based ST) with adiposity and physical fitness in youth; and ii) to analyse the mediation effect of physical activity (PA) on associations.

This study was conducted with 415 children (9.1 ± 0.4 years) and 853 adolescents (13.6 ± 1.6 years) in Spain during 2011–2012. Total ST and PA were assessed by accelerometry. Leisure-time spent in twelve sedentary behaviours was self-reported. Adiposity and physical fitness was measured following the ALPHA battery for youth.

Total accelerometer-based ST was positively associated with global adiposity score in children, and negatively associated with global physical fitness score in children and adolescents; but relationships were not independent of PA. PA mediated all associations of accelerometer-based and self-reported ST with adiposity or physical fitness in children. Conversely, screen-, educational-, social-, and other-based ST were negatively related to physical fitness in adolescents, independently of PA.

These findings give an impetus to developing effective strategies for specifically promoting PA in children and for increasing PA while reducing ST in adolescents in order to produce improvements on adiposity and physical fitness.  相似文献   

Functional shoulder ratios with high velocities of shoulder internal rotation are most sensitive to determine shoulder rotation torque imbalance: a cross-sectional study with elite handball players and controls     

Marcelo Peduzzi de Castro  Pedro Fonseca  Sara Tribuzi Morais  Márcio Borgonovo-Santos  Eduardo Filipe Cruz Coelho  Daniel Cury Ribeiro 《Sports biomechanics / International Society of Biomechanics in Sports》2019,18(1):39-50

The aim of the present study was to determine which approach to calculating shoulder ratios is the most sensitive for determining shoulder torque imbalance in handball players. Twenty-six participants (handball athletes, n = 13; healthy controls, n = 13) performed isokinetic concentric and eccentric shoulder internal rotation (IR) and external rotation (ER) assessment at 60, 180 and 300°/s. We used eight approaches to calculating shoulder ratios: four concentric (i.e. concentric ER torque divided by concentric IR torque), and four functional (i.e. eccentric ER torque divided by concentric IR torque) at the velocities of 60, 180 and 300°/s for both IR and ER, and combining 60°/s of ER and 300°/s of IR. A three factorial ANOVA (factors: shoulder ratios, upper limb sides, and groups) along with Tukey’s post-hoc analysis, and effect sizes were calculated. The findings suggested the functional shoulder ratio combining 60°/s of ER and 300°/s of IR is the most sensitive to detect differences between upper limbs for handball players, and between players and controls for the dominant side. The functional shoulder ratio combining 60°/s of ER with 300°/s of IR seems to present advantages over the other approaches for identifying upper limb asymmetries and differences in shoulder torque balance related to throwing.  相似文献
