Sincretismo y pensamiento categorial: génesis y diferencias socioculturales     

Jesús Palacios  Juan Daniel Ramírez 《Infancia y Aprendizaje》2013,36(11):54-66

Resumen

El estudio de la representación del mundo en el niño es una de las vías que permiten acercarse a la génesis del pensamiento infantil, a su progresiva estructuración. Interesados en la evolución del sincretismo y del pensamiento categorial, los diálogos con los niños en torno a las ultra-cosas nos han permitido detectar distintos niveles evolutivos dentro del pensamiento sincrétn o y del categorial y nos han puesto en la pista de posibles diferencias socioculturales ligadas con la pertenencia al medio rural o urbano.  相似文献   

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

Grade level, study time, and grade retention and their effects on motivation, self-regulated learning strategies, and mathematics achievement: a structural equation model     

Pedro Rosário  José Carlos Núñez  António Valle  Julio González-Pienda  Abílio Lourenço 《European Journal of Psychology of Education - EJPE》2013,28(4):1311-1331

The present study complements previous research findings with new data to improve our understanding of the relationship between motivational variables and academic performance in math mediated by self-regulated learning (SRL). A structural equation model with predictor (i.e., grade retention, grade level, and study time), process (i.e., perceived usefulness of SRL strategies, self-efficacy for the use of SRL strategies, and reported use of SRL), and product variables (i.e., academic achievement in mathematics) is proposed. The model was analyzed in two samples of data (calibration and validation samples). The first sample served to fit and respecify the model, and the second one was used to analyze the consistency of the findings of the first sample. A sample of 756 middle school Portuguese students participated in the current study. The results indicate that SRL is positively and significantly related to academic achievement and that the latter is, in turn, powerfully determined by perceived usefulness and self-efficacy, although students’ reported use of SRL strategies decreases from 7th to 9th grades. Self-efficacy and perceived usefulness of SRL strategies were also found to decrease as grade retention increased. These results are discussed with regard to the relevance of self-efficacy and perceived usefulness of SRL strategies in increasing academic achievement.  相似文献   

The role of Internet use and parental mediation on cyberbullying victimization among Spanish children from rural public schools     

Raúl Navarro  Cristina Serna  Verónica Martínez  Roberto Ruiz-Oliva 《European Journal of Psychology of Education - EJPE》2013,28(3):725-745

Cyberbullying victimization research on individual and familial correlates is scarce in Spain. By building upon previous studies, this research examines the role of Internet usage and parental mediation in online victimization. Spanish children from rural public schools (10–12 years; n?=?1068) completed a self-report questionnaire which measured being cyberbullied, Internet use and parental mediation strategies. Logistic regression analyses examined the association among cyberbullying victimization, online activities, intensity and purposes of online communication, and restricting, evaluating and co-using parental mediation. The results show that Internet use, specifically online communication, increases the likelihood of cyberbullying victimization. Conversely, monitoring software installed on the computer, joint creation of rules regarding the time spent online and personal information shared help lessen the likelihood of online victimization. The results are examined in the light of previous research, while implications for practice and future research are considered.  相似文献

我国图情档学科关于文化信息数字资源整合的研究——以博物馆研究为视角     

王萌  龙乐思  朱嘉麒 《图书馆杂志》2020,(4):80-91

我国图情档学科认为博物馆是文化信息数字资源整合的主体之一。博物馆中以其展品为代表的文化信息资源对满足公众多样化的文化需求、增强中华文化竞争力起着重要作用。本文借助Citespace分析软件,通过对作者、机构、关键词可视化图谱的绘制,识别出我国图情档学科下以博物馆为主题词的科研文献成果概况、科研机构分布及研究热点词与其研究发展趋势。经分析得知,该学科下以博物馆为主题的研究可以分为两个阶段:第一阶段(1996-2008年)主要是博物馆文献资源的开发与利用、博物馆与图书馆文献资源的开发与利用、博物馆古籍保护管理工作以及古籍文献等主题。第二阶段(2009-2019年)主要探讨三馆馆际合作的资源整合路径、数字资源整合理论模式与合作机制等的研究,并结合相关文献内容,深入探讨以博物馆为主题的研究重点,基于此,我国图情档学科应以博物馆中丰富多样的文化信息资源为视角,开展涵盖档案馆、图书馆、博物馆的全种类、全范围的全文化信息数字资源整合。最后,本文围绕数字资源整合这一具有影响力的研究热点,探讨如何从图情档学科的角度出发,有效地涵盖博物馆,构建以图书馆、档案馆、博物馆三馆为主体的数字资源整合模式与机制,建立为公众文化精神需求服务的信息共享平台。  相似文献   

Nutritional intake and body composition changes in a UCI World Tour cycling team during the Tour of Spain     

José Joaquín Muros  Cristóbal Sánchez-Muñoz  Jesús Hoyos  Mikel Zabala 《European Journal of Sport Science》2019,19(1):86-94

Abstract

The aim of this study was to quantify the food intake of an International Cyclist Union (UCI) World Tour professional cyclist team and to analyse changes in body composition during the Tour of Spain. Nine male professional road cyclists (31.3?±?3.0 years) volunteered to participate in the study. Nutritional data were collected each day throughout the 3-week Tour by two trained investigators who weighed the food ingested by the cyclists. Mean nutritional intake of the cyclists was as follows: carbohydrate, 12.5?±?1.8?g/kg/day of body weight (BW) (65.0?±?5.9%); fat, 1.5?±?0.5 g/kg/day BW (17.9?±?5.6%); and protein, 3.3?±?0.3?g/kg/day BW (17.1?±?1.6%). Intake of all micronutrients, except for folate, vitamin D and potassium (which were 78.7%, 46% and 84% of Recommended Dietary Allowances (RDA), respectively), exceeded the RDA. Height, weight, skinfolds, circumferences and diameters were taken following the guidelines outlined by the International Society for the Advancement of Kinanthropometry. Body density, body fat percentage, muscle mass, total muscle mass and fat mass of the arms and thighs were calculated. Percentage body fat, fat mass and upper arm fat mass significantly decreased (p < .05) after the Tour independent of the equation method used in the calculations. Total muscle mass remained unchanged. Generally, this sample of cyclists consumed more protein and less fat than the recommended amount and had low weight, BMI and fat mass. It is suggested that sports nutritionists design personalised diets in order to maintain a correct proportion of nutrients as well as controlling possible anthropometrical changes that could affect performance.  相似文献   

Topological metrics in academic genealogy graphs     

Luciano Rossi  Rafael J.P. Damaceno  Igor L. Freire  Etelvino J.H. Bechara  Jesús P. Mena-Chalco 《Journal of Informetrics》2018,12(4):1042-1058

Academic genealogy aims to structure and analyze the mentoring relationships between advisor and advisee. The representation of this structure results in academic genealogy graphs. For the analysis and characterization of these graphs, we present a set of metrics and their corresponding mirror metrics that capture the characteristics of its topological structure and represent them as quantitative attributes. The metrics of fecundity, fertility, descendants, cousins, generations, and relationships consider the descendants of the academics represented in the graph. The mirror metric of these topological metrics considers the ascendancy of academics. Individually, the metrics have strong semantic intuition and define characteristics regarding the performance in the mentoring of an academic. Together, the metrics are useful for the identification, characterization, and classification of communities and their members. The genealogical data available through the platforms of the Mathematics Genealogy Project and the Academic Family Tree were used as case studies. Two hundred thirteen thousand and 675,000 academic records were obtained for each project. We analyze the capacity of characterization of the metrics using the structuring of a similarity graph and through the distribution of the nodes in principal components. We observed that the set of metrics is capable of capturing the configuration pattern existing in genealogy graphs independently of its scale.  相似文献
