Comprensión de la inclusion jerárquica de clases Estudio evolutivo     

Jesús Alonso  Francisco Gutiérrez 《Infancia y Aprendizaje》2013,36(35-36):69-95

Resumen

En el presente trabajo se estudia el desarrollo de la comprensión de los principios que rigen la inclusión jerárquica de clases en sujetos de 4 a 14 años. Se presentan y comparan los resultados de tres experimentos en los que se utilizan, respectivamente, cuestiones de tipo piagetiano, problemas deductivos y problemas de inclusión con los cuantificadores «todos» y «algunos». Se examina también el efecto que diferentes variables definitorias de la estructura de las tareas tienen en el éxito o el fracaso en las mismas. Los resultados sugieren un desarrollo lineal progresivo en relación con la comprensión de la extensión diferente de clase y subclase, y la aplicación correcta de los cuantificadores, y un salto entre los 9 y 12 años en relación con la comprensión de la transitividad. Se discuten las implicaciones teóricas y prácticas de estos resultados.  相似文献   

La aproximación neuropsicológica a la dislexia evolutiva. I: Maduración cerebral     

Dionisio Manga  Francisco Ramos Campos 《Infancia y Aprendizaje》2013,36(34):43-55

Resumen

En los últimos años se constata un auge singular de la neuropsicología de las dificultades de aprendizaje, en especial de la neuropsicología de la dislexia evolutiva. En este trabajo se estudia, como posible explicación etiológica de la dislexia evolutiva, el fallo en el desarrollo madurativo cerebral; se revisan y analizan, a efectos de poder ofrecer pronósticos y modos de intervención apropiados, la diferencia entre la hipótesis del retraso y la del déficit en la maduración, así como la alternativa de restitución o sustitución en la recuperación funcional. Se examinan también otros problemas relacionados entre sí con la dislexia y con la neuropsicología del desarrollo, a saber, la base neurofistológica para formación de subgrupos disléxicos, la disfunción de secuenciación oculomotora como etiología de dislexia y, por fin, la luz que la dislexia adquirida aporta a la dislexia evolutiva al relacionar lesiones del lóbulo parietal inferior con el subdesarrollo madurativo de estas mismas zonas cerebrales.  相似文献   

La diferencia de sexo en la resolución de problemas aritméticos: un estudio transversal     

José Tomás Bethencourt  Esteban Torres 《Infancia y Aprendizaje》2013,36(38):9-20

Resumen

En este trabajo se estudia la diferencia entre los sexos en la resolución de problemas aritméticos verbales. Participaron 1.078 escolares de los grados 3.°, 4.°, 5.°, 6.° y 8.° de E.G.B. Se aplicó una prueba de 17 problemas aritméticos a los escolares de 3°, 4° y 5° en dos sesiones. También se aplicó una prueba de 4 problemas aritméticos a los escolares de 6.° y 8.° Los resultados indican que sólo en 8.° los varones son más hábiles que las mujeres resolviendo este tipo de problemas. Se hacen algunas consideraciones adicionales sobre los factores del contexto familiar y escolar que puedan incidir sobre los resultados.  相似文献   

Learning in collaborative settings: students building on each other’s ideas to promote their mathematical understanding     

John M. Francisco 《Educational Studies in Mathematics》2013,82(3):417-438

The purpose of this study is to contribute insights into how collaborative activity can help promote students’ mathematical understanding. A group of six high school students (15- to 16-year olds) worked together on a challenging probability task as part of a larger, after-school, longitudinal study on students’ development of mathematical ideas in problem-solving settings. The students solved the problem and produced a valid justification of their solution. This study shows that collaborative activity can help promote students’ mathematical understanding by providing opportunities for students to critically reexamine how they make claims from facts and also enable them to build on one another’s ideas to construct more sophisticated ways of reasoning. Implications for classroom teaching and ideas for future research are also discussed. The study helps address a documented need for a better understanding of how mathematical learning evolves in social settings.  相似文献   

Conceptualising gender and violence in research: Insights from studies in schools and communities in Kenya,Ghana and Mozambique     

Jenny Parkes  Jo Heslop  Samwel Oando  Susan Sabaa  Francisco Januario  Asmara Figue 《International Journal of Educational Development》2013

Gender and violence are complex and contested concepts, understood in varying ways in research, policy and interventions in education. Often there has been an emphasis on acts of violence, with much less attention to the social conditions and gender relations behind these acts. This paper discusses the development of a conceptual framework that emphasises not just acts and individuals, but also transformation of gendered power relations and inequities, alongside a focus on addressing the identity conflicts and struggles of everyday life. The framework underpins research, advocacy and community interventions in a multi-partnered project on violence against girls led by ActionAid.  相似文献   

LGBTQ+ health research guides at North American health sciences libraries: a survey and content analysis     

Gregg A. Stevens  Francisco J. Fajardo 《Journal of the Medical Library Association》2021,109(3):406

Objectives:Current literature recommends online research guides as an easy and effective tool to promote LGBTQ+ health information to both health care providers and the public. This cross-sectional study was designed to determine how extensive LGBTQ+ health guides are among hospital and academic libraries and which features are most prevalent.Methods:In order to locate LGBTQ+ health guides for content analysis, we searched for guides on the websites of libraries belonging to the Association of Academic Health Sciences Libraries (AAHSL) and the Canadian Association of Research Libraries (CARL). Additionally, we searched the Springshare interface for LibGuides with the word “health” and either “LGBT” or “transgender.” Content analysis was performed to identify major characteristics of the located guides, including target audience and the information type provided.Results:LGBTQ+ research guides were identified for 74 libraries. Of these, 5 were hospital libraries, and the rest were academic libraries. Of 158 AAHSL member libraries, 48 (30.4%) had LGBTQ+ guides on their websites. Nearly all guides (95.9%) provided general LGBTQ+ health information, and a large majority (87.8%) also had information resources for transgender health. Smaller percentages of guides contained information on HIV/AIDS (48.6%) and women''s health (16.2%).Conclusions:Even though literature recommends creating LGBTQ+ health guides, most health sciences libraries are missing an opportunity by not developing and maintaining these guides. Further research may be needed to determine the usage and usefulness of existing guides and to better identify barriers preventing libraries from creating guides.  相似文献   

Technological flows and choice of joint ventures in technology alliances   总被引：2，自引：0，他引：2  

Esteban García-Canal 《Research Policy》2008,37(1):97-114

This paper analyses the influence of technological flows in the choice of joint ventures as a governance form of technology alliances, using a theoretical framework based on Transaction Costs Economics and the Economics of Intellectual Property Rights. We argue that the formation of a joint venture is only necessary in situations for which technological flows make the monitoring of alliance activities and the distribution of cooperation rents difficult. Our hypotheses have been confirmed using a sample of technology alliances created by companies from the European Union between 1992 and 1999.  相似文献

Game-Based Learning in Virtual Worlds: A Multiuser Online Game for Medical Undergraduate Radiology Education within Second Life     

Rocio Lorenzo-Alvarez  Teodoro Rudolphi-Solero  Miguel J. Ruiz-Gomez  Francisco Sendra-Portero 《Anatomical sciences education》2020,13(5):602-617

Game-based learning can have a positive impact on medical education, and virtual worlds have great potential for supporting immersive online games. It is necessary to reinforce current medical students' knowledge about radiological anatomy and radiological signs. To meet this need, the objectives of this study were: to design a competition-based game in the virtual world, Second Life and to analyze the students' perceptions of Second Life and the game, as well as to analyze the medium-term retention of knowledge and the potential impact on the final grades. Ninety out of 197 (45.6%) third-year medical students voluntarily participated in an online game based on self-guided presentations and multiple-choice tests over six 6-day stages. Participants and non-participants were invited to perform an evaluation questionnaire about the experience and a post-exposure knowledge test. Participants rated the experience with mean scores equal to or higher than 8.1 on a 10-point scale, highlighting the professor (9.5 ± 1.1; mean ± SD) and the virtual environment (8.9 ± 1.1). Participants had better results in the post-exposure test than non-participants (59.0 ± 13.5 versus 45.3 ± 11.5; P < 0.001) and a lower percentage of answers left blank (6.7 ± 8.4 versus 13.1 ± 12.9; P = 0.014). Competitive game-based learning within Second Life is an effective and well-accepted means of teaching core radiological anatomy and radiological signs content to medical students. The higher medium-term outcomes obtained by participants may indicate effective learning with the game. Additionally, valuable positive perceptions about the game, the educational contents, and the potential benefit for their education were discovered among non-participants.  相似文献   

Defining,assessing, and developing creativity in sport: a systematic narrative review     

Francisco de Sa Fardilha  Justine B. Allen 《International review of sport and exercise psychology》2020,13(1):104-127

ABSTRACT

Research on creativity in sport is gaining momentum, due to a growing interest from coaches and academics in developing strategies to increase unpredictability in individual and collective behaviour which may allow teams to gain an important advantage over their opponents. The purpose of this paper was to conduct the first systematic narrative review of the literature on sporting creativity, critically synthesising 51 years of published research (1967–2018) and proposing avenues for future research. Six databases were used, and 48 documents met search criteria. The findings are organised in four categories: (a) defining creativity, (b) correlates of creativity, (c) assessing creativity and (d) developing creativity. Creativity definitions and assessments have privileged thought processes over the ability to act. A distinction is warranted between creativity about sport and creativity in sport (in action) and aligned assessment methods. The literature does not support a single strategy for the development of sporting creativity but does support its trainability. Evidence of the effectiveness of programmes for the enhancement of sporting creativity is growing but is still limited. Furthermore, while it is recognised that coaches have a pivotal role in the development of sporting creativity, research involving them is still scarce.  相似文献
