Comprensión de conceptos históricos durante la adolescencia     

Mario Carretero  Juan Ignacio Pozo  Mikel Asensio 《Infancia y Aprendizaje》2013,36(23):55-74

Resumen

En este articulo se plantea una discusión acerca de la teoria e investigaciones más relevantes sobre el desarrollo de la comprensión de la historia en el niño. Desde una perspectiva piagetiana se estudian los procesos cognitivos involucrados en la realización de tareas históricas. Se exponen los resultados de una investigación sobre 175 niños acerca de la comprensión de conceptos utilizados comúnmente en la enseñanza de la Historia y una segunda investigación sobre 695 niños acerca de la comprensión y uso de la noción de tiempo cronológico. Los resultados ponen de manifiesto la gran dificultad de este tipo de tareas y su evolución con la edad.  相似文献   

Enseñanza de la lengua escrita. ¿A qué edad?     

Mario G. Rodríguez 《Infancia y Aprendizaje》2013,36(30):39-50

Resumen

En este estudio se pasa revista a la polémica suscitada, ya desde antiguo, en torno a la edad de comienzo de la enseñanza formal de la lengua escrita.

A la luz de las opiniones vertidas por distintos autores, y contando con la muy valiosa aportación de profesores con larga experiencia en educación preescolar, se analizan tanto la posibilidad de un aprendizaje precoz como la oportunidad de tan temprano comienzo.

El autor del artículo señala, como conclusión, lo improcedente de una iniciación precoz en la enseñanza de la lecto-escritura, si con ello se dificulta el tratamiento de aspectos de mayor transcendencia en la formación del niño en los primeros estadios de su vida.  相似文献   

Defining the problem: key element for the success of knowledge management     

Mario?Barcelo-ValenzuelaEmail author  Gerardo?Sanchez-Schmitz  Alonso?Perez-Soltero  Fernando?Martín Rubio  José?Palma 《知识管理研究与实践》2008,6(4):322-333

The objective of this paper is to propose a methodology for applying knowledge management (KM), in which we first focus on explaining problematic areas of an organization by identifying the knowledge core process, before applying KM strategies to those processes. For the methodology, we lean on the larger context of systems thinking to help visualize the whole organization, and it is here that the key factors are identified and a set of strategic criteria is established. The most important criteria are then used to evaluate the associated processes and their respective tasks in order to establish the problematic areas or opportunities where KM initiatives can be applied. This strategy precludes tackling all the organization's problems and allows management to focus on only those processes that provide significant and manageable knowledge. Finally, this study explores and cautiously recommends an unexploited but valuable element to be taken into account when implementing KM initiatives.  相似文献   

Energy: Between Physics and Metaphysics     

Mario Bunge 《Science & Education》2000,9(5):459-463

The general concept of energy is somewhat unclear as long as it is confined to physics, since every chapter of it defines its own particular concept of energy. The general concept can be elucidated in terms of the hypergeneral (philosophical) concepts of concrete thing and changeability. In this way one succeeds in crafting a minitheory that identifies energy with mutability, and that regards it, as well as its conservation, as a universal property of concrete things. The moral is that physicists and philosophers can learn from one another.  相似文献   

Ein interaktionsbasiertes Modell für den objektorientierten Integrations- und Regressionstest     

Mario Winter 《Informatik - Forschung und Entwicklung》2000,15(3):121-132

Zusammenfassung.   Bei der iterativen, inkrementellen Software-Entwicklung werden Klassen sukzessive spezifiziert, implementiert bzw. ge?ndert oder erweitert, klassengetestet und zu einem ausführbaren Anwendungssystem integriert. Integrations- und Regressionstest stellen dabei besonders wichtige und h?ufig ausgeführte Testaktivit?ten dar, die zudem aufgrund der vielf?ltigen Interaktionsm?glichkeiten in objektorientierten Programmen sehr komplex sind. Integrations- und Regressionstest werden in der Literatur stets separat behandelt, obwohl sie durchaus ?hnliche Teilaktivit?ten beinhalten. Bestehende Ans?tze zum objektorientierten Integrationstest betrachten entweder strukturelle oder verhaltensorientierte Systembeschreibungen. In diesem Beitrag stellen wir das Klassen-Botschaftsdiagramm (KBD) vor, ein Struktur und Verhalten objektorientierter Programme gleicherma?en berücksichtigendes interaktionsbasiertes (Test-)Modell. Wir skizzieren Algorithmen zur ?nderungsanalyse, Ableitung einer Integrationsstrategie und Auswahl von Regressionstestf?llen nach der Modifikation bestehender Klassen. Abschlie?end werden die Ergebnisse einiger mit Smalltalk-80 Klassen durchgeführter Experimente zur Evaluierung des Verfahrens vorgestellt. Eingegangen am 14. Dezember 1999 / Angenommen am 19. Juni 2000  相似文献

Identification of temporal factors related to shot performance for indoor recurve archery     

Andrew J. Callaway  Johanna Wiedlack  Mario Heller 《Journal of sports sciences》2017,35(12):1142-1147

The purpose of this study was to investigate the temporal phases of the archery shot cycle that distinguish the arrows distance from centre, in an attempt to understand critical factors that affect performance. Fifteen archers of varying ability each performed 30 shots at 18 m. Fourteen potential predictor variables were measured for statistical modelling by stepwise multiple linear regression. The results show that pre-shot time (pre-performance routine), follow-through time (post-performance routine), aiming time, speed of the arrow and the %variation in clicker-release time, account for 7.7% of the variation in predicting shot performance. The results have implications for practice demonstrating factors that coaches should focus on to develop their athletes. Further work on pre-, but more importantly, post-performance routines are needed generally within sport research as they are lacking and have been shown to be important contributing factors in a number of sports.  相似文献   

Color characterization of roofing slates from the Iberian Peninsula for restoration purposes     

Beatriz Prieto  Perla Ferrer  Patricia Sanmartín  Victor Cárdenes  Benita Silva 《Journal of Cultural Heritage》2011,12(4):420

Substitution of slate roofing tiles is a conventional operation during building restoration, since tiles are very difficult to restore or clean because of the high degree of alteration they suffer. Criteria for replacement of historical building stones must be based on geological, geotechnical and esthetic parameters, among which color is of great importance. In this sense, this paper constitutes a comprehensive and useful colorimetric study of roofing slates from the Iberian Peninsula, for the purposes of restoration. The color of 50 commercial varieties of roofing slate mined in quarries from the 12 mining districts in the Iberian Peninsula was analyzed with a spectrophotometer device, by considering the CIELAB color space. The results of the study were used to develop a protocol for characterizing the color of roofing slate and to define the color range of roofing slate from the Iberian Peninsula. In addition, the similarities and differences in the color and microstructure of the different commercial varieties of Iberian roofing slate were established and the limit of acceptability of replacement of one type of slate by another was determined. Parameter h_ab was found to be the most important CIELAB color coordinate as regards the formation of homogeneous color groups, and the specular component excluded (SCE) mode was most sensitive as regards detecting color differences between two samples.  相似文献
