La integración de Internet en la educación escolar española : situación actual y perspectivas de futuro

The main objectives and findings of this first research report are presented in this chapter."The Implementation of the Internet in the Spanish Education System: State of Affairs and Future Prospects" is a large-scale research project that seeks to obtain relevant data about the introduction and dissemination of Information and Communication Technology, particularly the internet, in the practical and organizational general procedures of the Spanish schools and high schools. The project articulates the processes of ICT implementation on the primary and secondary education levels embracing a holistic approach, propped up by an empirical and analytical research methodology. Thus, our survey does not intend to detect which is the impact of ICT on school activities but how all the agents involved in the school community incorporate ICT and what use they make of it. We are especially interested in identifying the teachers' pedagogical and professional uses of ICT, how students use it in their activities and to what extent it contributes in reinforcing teamwork and participation proceedings in the institutions, as well as the relations between the latter and their context. It is also of our interest to know the factors that exert the strongest influence on the way teachers, head teachers and students make use of ICT. Finally, we intend to identify the ways ICT may contribute to the improvementof educational practices.

Conhecimento escolar em química: processo de mediação didática da ciência

xThe aim of this article is to present a contribution of the school knowledge research to Chemistry Teaching. The object of research is school knowledge on physical sciences, considering the existence of a rupture between scientific knowledge and everyday knowledge. The differences between analogies and metaphors and the process of didactic mediation were thoroughly examined. The conclusion is that the process of didactic mediation is built on their own cognitive configurations, which not always make public the private scientific knowledge to certain social groups.

Evaluación del acceso a la dirección escolar en los centros públicos del País Vasco

The article summarises a piece of research carried out in the Basque Country involving headmasters and headmistresses who are going to apply for a management position in the 2009-2010 academic year. This study aims to analyse the process to access management in state schools in this region. The results from the research indicate that, depending on the candidates, the suitable management acces procedure involves School Council selection, by process of elimination, depending on the Management Project presented and the academic merits accredited by the candidate to a lesser extent.

La búsqueda de factores protectores del fracaso escolar en niños en situación de riesgo mediante un estudio de casos

The aim of this article is to introduce one of the approaches of research that we consider may contribute to find useful knowledge for prevention of school failure. This approach is in some studies called the study of risk and resilience. The word resilience refers to the capacity of individuals to endure adverse events in their vital experience, without long-term negative or disrupting consequences in their development or socialisation. We present a review of studies that have been carried out with this approach. Then it will be exemplified with a research that intended to identify protective factors of the risk of school failure in at risk adolescents. By means of a qualitative case study approach, this research has allowed us to approach some personal, educational and social factors that seem to have a certain relevance as protective factors of the risk of school failure

Uma célula simples para adaptação de eletrodos seletivos comerciais em sistemas de análises em fluxo

A simple flow cell for potentiometric detection is described. It was assembled by making use of two perspex pieces fixed together by means of four screws, and allow the connection of plane membrane conventional electrodes to flow system. Details about its construction are presented. The device performance was evaluated by making use of a cyanide ion-selective electrode. The relative standard deviation was about 0.5% with a detection limit of 8.0 x 10-6 mol CN- dm-3. Under experimental conditions, the linear range was 10-5 to10-2 mol dm-3.

Adaptació escolar, actituds i aprenentatge del català en l'alumnat de les aules d'acollida de primària i secundària a Catalunya (curs 2005-2006)

En aquest article volem presentar les dades generals obtingudes en dues proves elaborades pel Departament d'Educació per a avaluar les aules d’acollida. Una prova de coneixement de català i una prova d’integració i adaptació escolar

Redução seletiva aplicada à especiação de mercúrio em peixes: uma adaptação do método de Magos

In the selective reduction procedure proposed by Magos SnCl2 was used as reductant for inorganic mercury while total mercury was determined after reduction with a mixture of SnCl2 and CdCl2. The difference between total mercury and inorganic mercury determines the content of organic mercury. The procedure of the present work differs of Magos in that the mercury vapour is carried to the absorption cell after magnetic stirring of the solution in the reaction flask; in the Magos procedure, mercury vapour is carried by bubbling the gas in to the solution. In contrast to the Magos procedure this slight modification overcame the necessity of at calibration by analyte addition, saving time and gainning accuracy.

El valor de la impremta en el Grup Escolar Lluís Vives: una eina al servei de l"educació durant la II República i de la recuperació de la memòria pedagògica

Les revistes, els periòdics, els gravats i altres impresos que van sortir de les impremtes dels grups escolars del Patronat Escolar són el testimoni directe dels nens i les nenes que van viure una revolució pedagògica molt intensa en un període de temps molt reduït, ja que la guerra va estroncar el projecte educatiu. Concretament, analitzarem dues fonts documentals procedents del Grup Escolar Lluís Vives: d"una banda, el primer i únic número de la revista Vives, publicat el maig del 1936, i de l"altra, la carpeta de linogravats titulada Llibre de la natura. Ambdues publicacions permeten fer-nos una idea bastant ajustada de com era l"escola, quins eren els mètodes d"aprenentatge que se seguien i quins valors s"hi fomentaven. En definitiva, constitueixen un testimoni del dietari pedagògic de l"escola i ens permeten ratificar els idearis dels grups escolars del Patronat Escolar i de les escoles municipals de Barcelona durant la II República.

Adaptação no método do peso da gota para determinação da tensão superficial: um método simplificado para a quantificação da CMC de surfactantes no ensino da química

The discussion based on surfactant cleaning action is commonly used in chemistry classrooms for the comprehension of theoretical concepts related to surface tension and micelle formation. The experimental quantification of surface tension of aqueous solutions of surfactants provides the practical instruments for this discussion. The present paper describes a simplification on the common apparatus employed for the drop-weight method, making the determination of surface tension accessible to any chemistry lab. The surface tension of various liquids and the critical micelle concentration, CMC, of three commercial surfactants were measured with this modified method, and proved to be consistent with literature values.

Aproximación a los ritmos de rendimiento escolar: fundamentos y aplicaciones actuales

El análisis de los ritmos se realiza desde el contexto de dos disciplinas interrelacionadas: la cronopsicología, que se ocupa de estudiar los ritmos de comportamiento por ellos mismos (Fraisse, 1980) y la cronobiología, que estudia las oscilaciones rítmicas de los parámetros biológicos (Halberg, 1979). El objetivo de las investigaciones cronopsicológicas consiste básicamente en analizar la variabilidad temporal que presentan distintas variables comportamentales, como la memoria, la atención o el rendimiento escolar, entre otros. Desde una perspectiva cronobiológica, en cambio, el interés se centra en el estudio de distintos aspectos biológicos, como el ritmo sueño-vigilia, la temperatura corporal, los ritmos nutricionales, el ritmo cardíaco, etc

Adaptação de forno de microondas doméstico para realização de reações de transesterificação sob refluxo e catálise por argilas

The microwave oven became an important source of heating for many laboratory procedures including accelerating organic reactions. Reactions that require long reflux times can sometimes be carried out in a few hours or minutes in a conventional microwave oven. However, longer reflux times can be troublesome since domestic microwave ovens are not prepared for these harsh conditions. This technical note presents our finding on heterogeneous catalysis transesterification reactions between b-keto-esters and carbohydrate derivatives under heating or microwave irradiation using an adapted domestic microwave oven.
