La Maîtrise Intuitive des Relations entre Masse,Volume et Masse Volumique Chez des Elèves du Premier Cycle

Three experiments have been devoted to the application of the methodology developped by Anderson, N. H. (1981, 1982) in the framework of the Information Integration Theory to the problem of the mastery by children (14 old) of the relations between the notions of mass, volume and volumic mass. It appears that, having to judge of the mass values of diverses objects from given values of volume and volumic mass, a majority of pupils are able to take account of the positive link between the mass on the one part and the volume and the volumic mass on the other part but apply an additive type integration rule. However, a minority of pupils are able to apply a normatively correct multiplicative rule. Concerning the judgements of volume values from given mass and volumic mass values, and the judgements of volumic mass values from given mass and volume values, a majority of pupils apply a soustractive integration rule. In these two cases however the integration patterns are extremely variegated. The relation between the algebraic level of analysis of the judgement data and an information processing level of analysis of the same data is discussed. The use by teachers of the paradigm presented in the study with the aim of improving upon the current evaluation methods is proposed.     

Radio as a Sociability Space

This article aims to analyze community radio stations from their very physical spaces, where social relations and opinions are elaborated, but also outside the actual studio during the various events that they may sponsor. Combining anthropology and history, it sheds a new light on the role played by US community radios in shaping the semantic of the New Left from the 1950s onwards.     

MAGIS: mobile augmented-reality games for instructional support

ABSTRACT

We present Mobile Augmented-Reality Games for Instructional Support (MAGIS), a framework for the development of mobile augmented-reality (AR) games for education. The framework supports off-the-shelf, state-of-the-art technologies that enable AR tracking and rendering on consumer-level mobile devices, and integrates these technologies with content-generation tools that simplify the development of educational AR games, especially those that extensively use narrative-based game design and player-location tracking such as location-based historical or museum adventure games. We use Igpaw: Intramuros, a proof-of-concept game developed using MAGIS, to help describe the current state of the framework and to show its efficacy for implementing outdoor location-based educational games, and we briefly outline future development plans to improve MAGIS’ AR support (especially those involving indoor scenarios) as well as to improve the instructional design and authoring phases of AR applications written using this framework.     

Emotional intelligence and academic attainment of British secondary school children: a cross-sectional survey

Trait emotional intelligence (trait EI) covers a wide range of self-perceived skills and personality dispositions such as motivation, confidence, optimism, peer relations and coping with stress. In the last few years, there has been a growing awareness that social and emotional factors play an important part in students’ academic success and it has been claimed that those with high scores on a trait EI measure perform better. This research investigated whether scores on a questionnaire measure of trait EI were related to school performance in a sample of British pupils. Results showed that high performing students had higher trait EI scores than low performing students and that some aspects of trait EI (motivation and low impulsivity) as well as total trait EI were significant predictors of academic achievement after controlling for prior attainment at school. Therefore, initiatives to develop the emotional and social abilities of schoolchildren might be worthwhile and more effective than concentrating solely on teaching and curriculum activities.     

La comprensión por el niño de la intención del mensaje publicitario

Resumen

El propósito central de este artículo es mostrar cómo un modelo integrado, multidisciplinar, puede dar cuenta de la comprensión del mensaje publicitario por el niño. El modelo parte de la consideración del mensaje como acto-de-habla-global y su representación cognitiva por el receptor, como esquema de acción e interacción. Este doble abordamiento permite trascender el marco de las teorías de la competencia, hasta ahora dominantes, y explicar, en cierto modo, la actuación concreta de los sujetos en la comprensión de los mensajes.     

Does moderate-intensity continuous training result in greater total energy expenditure compared to high-intensity interval training?

Recently in the Journal of Sports Sciences, Schaun et al. published a study on the comparison of energy expenditure between high-intensity interval training and moderate continuous training performed in water. With this Letter to the Editor, we would like to comment on the methodological aspects that should be considered to analyze the results presented, as well as the conclusions.

Abbreviations: CONT, moderate-intensity continuous training; EPOC, excess post-exercise oxygen consumption; HIIT, high-intensity interval training; VO2max, maximal oxygen consumption.     

Inquiry projects for scientific education: a good option for compulsory secondary education / Proyectos de indagación para la educación científica: una buena opción para la educación secundaria obligatoria

The approach of learning science through inquiry presents significant challenges for teachers and students. In light of this, an extensive experience has been developed in which students without any previous training or specific interests have been organized into small groups to carry out scientific inquiry projects guided by their teachers. Evaluation of the experience is clearly positive, and is based on questionnaires completed at the end of the experience by the students as well as retrospective reports provided by their teachers. Despite this, some problems are presented, such as the difficulty or repetitiveness of some scientific practices mentioned by some students, or when the inquiry or the group does not work out in some cases, as mentioned by teachers. Scientific inquiry projects like the one described here could play a key role in science education in compulsory secondary education.     

The research environment of universities

Part‐time study is one of the foci of the widening participation agenda in the UK. The experiences of part‐time students, however, have received remarkably little attention from scholars, especially in a comparative context. This paper explores existing historical data going back over a decade to identify the main themes of part‐time experience at a number of UK higher education institutions and how it compares and contrasts with the full‐time experience. The surveys use the Student Satisfaction Approach. The main themes emerging from institutional survey data over time are the work/family/study balance, assessment and feedback, access to learning and catering resources, and students' financial situation. There is sometimes a question of identity, but unlike many studies of part‐time student experience, which focus on aspects of disadvantage, social, and cultural capital, the data for this paper indicate that many part‐time students have a sense of themselves as being ignored or at worst marginalised in contemporary higher education.
