ResumenEn 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

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

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

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.

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

In recent years the concept of learning ecology has been interpreted in different ways to highlight its potential for learning and professional development. However, there are several aspects that still deserve to be understood such as, eg, the role that the different contexts come to play within a learning ecology. For this purpose, this paper presents and discusses the results of a study exploring the learning ecologies of educators in a blended programme delivered in higher education. The participants in the study were 85 professionals in the field of education aged between 28 and 58 years. The research design adopted here can be defined as a convergent mixed method where both quantitative and qualitative data were collected through an e-portfolio. The study found that educators in the sample had different postures, of whom some more aware of their professional roles or Self than others. Moreover, different professional identities seemed to be linked to different learning ecologies, where elements like formal or informal education, cultural artefacts, personal experiences, colleagues or work experiences played a different role. Formal education emerged as having a questionable function, while colleagues came up as a crucial resource. 相似文献
