Towards the reform of science teaching in Spain: the social and personal relevance of junior secondary school science projects for a socially responsible understanding of science     

Pedro Membiela 《International Journal of Science Education》2013,35(7):721-730

This article describes aspects of more than a decade of research and implementation of cross-curriculum themes as part of the curriculum for secondary school students in Spain. The educational reform described is an attempt to develop a more socially responsible education, using what, for Spain, has been a highly novel breaking down of subject barriers as a way of preparing young adults for life as citizens. It provides other investigators in the field with a commentary on some of the theoretical and practical issues encountered in developing similar projects.  相似文献   

La comprensión por el niño de la intención del mensaje publicitario     

Pedro Vidal 《Infancia y Aprendizaje》2013,36(35-36):123-138

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.  相似文献

Serial position effects in social transmission of food preference     

Juárez-Maldonado CE  Ortega-Saavedra G  Huichan-Olivares F  Gómez-Romero J  Cruz-Morales SE  Arriaga-Ramírez JC 《Learning & behavior》2006,34(4):374-378

The serial position effect in Long-Evans rats was evaluated in two experiments. In Experiment 1, the effect in a group for which an interstimulus interval (ISI) was introduced between items in a list of demonstrators was compared with that in a group without an ISI. With an ISI, a recency effect was produced. In Experiment 2, a serial position effect group was compared with four groups in which either the distinctiveness or the context of the middle item was changed, relative to the items on either side of it. A von Restorff effect was produced when a rat from a different strain was used as a demonstrator in Position 2. The results for Experiment 1 are discussed in relation to interstimulus effects in monkeys and those for Experiment 2 with respect to changes in the physical properties of middle items.  相似文献   

High-throughput study of alpha-synuclein expression in yeast using microfluidics for control of local cellular microenvironment   总被引：1，自引：0，他引：1  

Rosa P  Tenreiro S  Chu V  Outeiro TF  Conde JP 《Biomicrofluidics》2012,6(1):14109-141099

Microfluidics is an emerging technology which allows the miniaturization, integration, and automation of fluid handling processes. Microfluidic systems offer low sample consumption, significantly reduced processing time, and the prospect of massive parallelization. A microfluidic platform was developed for the control of the soluble cellular microenvironment of Saccharomyces cerevisiae cells, which enabled high-throughput monitoring of the controlled expression of alpha-synuclein (aSyn), a protein involved in Parkinson's disease. Y-shaped structures were fabricated using particle desorption mass spectrometry-based soft-lithography techniques to generate biomolecular gradients along a microchannel. Cell traps integrated along the microchannel allowed the positioning and monitoring of cells in precise locations, where different, well-controlled chemical environments were established. S. cerevisiae cells genetically engineered to encode the fusion protein aSyn-GFP (green fluorescent protein) under the control of GAL1, a galactose inducible promoter, were loaded in the microfluidic structure. A galactose concentration gradient was established in the channel and a time-dependent aSyn-GFP expression was obtained as a function of the positioning of cells along the galactose gradient. Our results demonstrate the applicability of this microfluidic platform to the spatiotemporal control of cellular microenvironment and open a range of possibilities for the study of cellular processes based on single-cell analysis.  相似文献   

Proximity-to-goal as a constraint on patterns of behaviour in attacker-defender dyads in team games     

Headrick J  Davids K  Renshaw I  Araújo D  Passos P  Fernandes O 《Journal of sports sciences》2012,30(3):247-253

The aim of this study was to determine whether spatiotemporal interactions between footballers and the ball in 1 vs. 1 sub-phases are influenced by their proximity to the goal area. Twelve participants (age 15.3 ± 0.5 years) performed as attackers and defenders in 1 vs. 1 dyads across three field positions: (a) attacking the goal, (b) in midfield, and (c) advancing away from the goal area. In each position, the dribbler was required to move beyond an immediate defender with the ball towards the opposition goal. Interactions of attacker-defender dyads were filmed with player and ball displacement trajectories digitized using manual tracking software. One-way repeated measures analysis of variance was used to examine differences in mean defender-to-ball distance after this value had stabilized. Maximum attacker-to-ball distance was also compared as a function of proximity-to-goal. Significant differences were observed for defender-to-ball distance between locations (a) and (c) at the moment when the defender-to-ball distance had stabilized (a: 1.69 ± 0.64 m; c: 1.15 ± 0.59 m; P < 0.05). Findings indicate that proximity-to-goal influenced the performance of players, particularly when attacking or advancing away from goal areas, providing implications for training design in football. In this study, the task constraints of football revealed subtly different player interactions than observed in previous studies of dyadic systems in basketball and rugby union.  相似文献   

Interpersonal dynamics and relative positioning to scoring target of performers in 1 vs. 1 sub-phases of team sports     

PT Esteves  D Araújo  K Davids  L Vilar  B Travassos  C Esteves 《Journal of sports sciences》2012,30(12):1285-1293

Abstract In this study, we examined the effects of relative positioning of attacker-defender dyads to the basket on interpersonal coordination tendencies in basketball. To achieve this aim, four right-hand dominant basketball players performed in a 1 vs. 1 sub-phase, at nine different playing locations relative to the basket (from 0° to 180°, in 20° increments). Performers' movement displacement trajectories were video-recorded and digitized in 162 trials. Results showed that interpersonal coordination tendencies changed according to the scaling of the relative position of performers to the basket. Stable in-phase modes of coordination were observed between performers' longitudinal and lateral displacements (50.47% and 43.02%) on the left side of the court. On the right side of the court, a shift in the dominant mode of coordination was observed to a defender lead-lag of -30°, both for longitudinal and lateral displacements (30.51% and 32.65%). These results suggest how information about dribbler hand dominance and relative position to the basket may have constrained attacker-defender coordination tendencies in 1 vs. 1 sub-phases of basketball.  相似文献   

Private Higher Education and Diversity: An Exploratory Survey     

Pedro Teixeira  & Alberto Amaral 《Higher Education Quarterly》2001,55(4):359-395

In this preliminary review, the authors analyse the effects of privatisation on diversity in higher education (HE) systems by exploring the consequences of the establishment of HE Institutions by non-public organisations. The rising importance of privatisation in Europe (Western and transitional economies), Latin America, and Southeast Asia is analysed. Then follows detailed examinations of private-sector HE in countries representative of all these geographical areas to determine how far privatisation has stimulated diversity. The preliminary results indicate that in each case the private sub-sector has promoted limited and partial diversification. In general, though, the more recent private establishments, created to satisfy increasing demand for HE, have nonetheless focused predominately on teaching, have undertaken little, or no, research and appear to be of lower quality than the older institutions. The private sub-sector is characterised mostly by its low-risk behaviour, and a concentration on low-cost and/or safer initiatives. Public authorities must share at least a partial responsibility for some of the negative side effects of the development of private higher education.  相似文献

João Pedro da Ponte  Hélia Oliveira  José Manuel Varandas 《Journal of Mathematics Teacher Education》2002,5(2):93-115

This paper describes the workundertaken in a course in communication andinformation technology in a pre-service programfor secondary school mathematics teachers. Thiscourse aimed to help pre-service teachersdevelop a positive attitude regarding ICT anduse it confidently. It focused on theexploration of educational software and of theInternet's potential as a means of research andproduction of web sites. We discuss how thepre-service mathematics teachers evaluate theirwork concerning their commitment, difficultiesthey found, learning they identified, andpersonal relationship. We also analyse theeffects of the course on the development oftheir professional knowledge and identity.  相似文献
