The use (and misuse) of PISA in guiding policy reform: the case of Spain     

Álvaro Choi  John Jerrim 《比较教育学》2016,52(2):230-245

In 2013 Spain introduced a series of educational reforms explicitly inspired by the Programme for International Student Assessment (PISA) 2012 results. These reforms were mainly implemented in secondary education – based upon the assumption that this is where Spain's educational problems lie. This paper questions this assumption by attempting to identify the point where Spanish children fall behind young people in other developed countries. Specifically, by drawing data from multiple international assessments, we are able to explore how cross-national differences in reading skills change as children age. Consideration is given to both the average level of achievement and the evolution of educational inequalities. Our conclusion is that policy-makers have focused their efforts on the wrong part of the education system; educational achievement is low in Spain (and educational inequalities large) long before children enter secondary school. This study therefore serves as a note of caution against simplistic interpretation of the PISA rankings.  相似文献

Exploring affiliation network models as a collaborative filtering mechanism in e-learning     

Daniel Rodríguez  Miguel Ángel Sicilia  Salvador Sánchez-Alonso  Leonardo Lezcano  Elena García-Barriocanal 《Interactive Learning Environments》2013,21(4):317-331

The online interaction of learners and tutors in activities with concrete objectives provides a valuable source of data that can be analyzed for different purposes. One of these purposes is the use of the information extracted from that interaction to aid tutors and learners in decision making about either the configuration of further learning activities or the filtering of learning resources. This article explores the use of an affiliation network model for such kind of purposes. Concretely, the use of techniques such as blockmodeling – a technique used to derive meaningful patterns of relationships in the network – and the analysis of m-slices – a technique helpful to study cohesion in relationships – are explored as tools to decide on the configuration of topics and/or learner groups. In particular, the results of the case study show that such techniques can be used to (i) filter participants for rearranging groups; (ii) rearrange topics of interest; and (iii) dynamically change the structure of a course. The techniques presented can be considered a case of collaborative filtering based on social network structure.  相似文献   

Communist media economics and the consumers: The case of the print media of East Central Europe     

Ágnes Gulyás 《媒体管理杂志》2013,15(2):74-81

Abstract

Entrepreneurship theory complements established approaches to media management research with an alternative frame for viewing media ownership and the media's capacity for content diversity. Established entrepreneurship metrics were applied to media industries in the United States. All media sectors experienced varying rates in the second half of the last century; by the turn of the new century, nearly all were more entrepreneurial than any other U.S. service or manufacturing industry.  相似文献

Acceleration Nation: An Investigation into the Violence of Speed and the Uses of Accidents in Iceland     

Arnar Árnason  Sigurjón Baldur Hafsteinsson  Tinna Grétarsdóttir 《Culture, Theory & Critique》2013,54(2):199-217

Abstract

There are two starting points from which this paper is constructed: first, Virilio’s observation that the wealth of societies is founded on their dromocratic condition, that the faster societies accelerate their citizens, commercial goods and communication the more political and economic power they have and, second, the links that he traces between technologies of speed and acceleration and the accident. We suggest that Virilio’s ideas on this invite and deserve a closer ethnographic scrutiny than they have so far received, scrutiny that highlights the varied ways in which speed, acceleration and the accident are articulated in different cultural contexts. To this end we offer an investigation into the dromocratic condition, the violence of speed and the uses of accidents in Iceland.  相似文献   

Human kinematics and event control: on-line movement registration as a means for experimental manipulation     

RAÔUL OUDEJANS  BERT COOLEN 《Journal of sports sciences》2013,31(7):567-576

In human movement and sports science, manipulations of perception and action are common and often comprise the control of events, such as opening or closing liquid crystal goggles. Most of these events are externally controlled, independent of the actions of the participants. Less common, although sometimes desirable, are event manipulations that are dependent on the unconstrained movements of participants. As an example, we describe a method we used previously to manipulate vision of basketball jump shooters on the basis of on-line registration of their own movements. The shooters wore liquid crystal goggles that opened or shut as a function of specific kinematic features of these movements. The novel aspect of this method is that the criteria for detecting movement patterns and performing the appropriate manipulations are adjustable to the specific sport context and the complexity and variations of the unconstrained movements. The method was implemented as a finite state machine: a computer system that can be used for pattern recognition. We discuss this method, how it works and the potential it has for studying perceptual-motor skills in sport. Furthermore, the results of the basketball experiment are briefly summarized and complemented with new analyses.  相似文献   

Tres pies al gato: significado,sentido y cultura cotidiana en la educación     

Pablo Del Río  Amelia Álvarez 《Infancia y Aprendizaje》2013,36(59-60):43-61

Resumen

Se pasa revista en este artículo a los tres ejes que conforman la línea de investigación de los autores en psicología de la educación, a saber, considerar la arquitectura, no sólo cognitiva, sino instrumental y cultural, del significado; la necesidad de unir en la investigación y en el diseño educativo las vertientes de significado y de sentido que caracterizan el funcionamiento psicológico de los individuos, y que solo se articulan sobre la base de sistemas de actividad; por último, la necesidad de contemplar las formas de representación humanas menos formalizadas y desdeñadas hasta hace muy poco por la psicología de la educación: las denominadas bajo el epígrafe de conocimiento informal. En torno a estos tres ejes, se exponen ejemplos de investigación y de intervención que conforman lo que hemos denominado diseño cultural.  相似文献   

Comprehensiveness and diversity in secondary compulsory education in andalusia: an unresolved challenge     

Ángel Pérez ómez  Miguel Sola FernÁndez  Javier Barquín Ruiz  Nieves Blanco  Encarnación Soto Gómez 《Educational Action Research》2013,21(4):473-492

This article outlines the contradictions and challenges of introducing comprehensive, compulsory education in Andalusia for students up to the age of 16. Following a documenting of the developments, it is argued that while the intention was for a significant, planned reform, it is better characterised as one that is, at best, an improvisation. The article discusses the continuing difficulties that may be attributed to a number of policies of the Conservative government of the day, which allowed the development of two systems of education that were not grounded in concepts of equity and social justice to evolve. The work of John Elliott has been acknowledged as an important influence upon the inquiry that was undertaken and the subsequent analysis of its results. Thus, not only are the results of an action-orientated study reported here, but also there is an extensive set of guiding principles that could enable the reform to be truly actualised.  相似文献   

An unexpected world population variation of MCT1 polymorphism 1470T > A involved in lactate transport     

Federico Onali  Carla M. Calò  Myosotis Massidda  Miguel M. Álvarez-Álvarez 《European Journal of Sport Science》2018,18(10):1376-1382

A common missense mutation (1470T > A) in gene SLC16A1 responsible for an amino acid substitution in protein MCT1 has been associated with differential lactate transport and hence, differences in physical performance and muscle injuries in relation to physical exercise. This study describes, for the first time, the worldwide variation of MCT1 variant 1470T > A at an intra- and inter-continental level. Two thousand five hundred and four individual genotypes of 26 populations clustered in 5 population groups have been analysed with data downloaded from the public database 1000 Genomes Phase 3 Browser. Several parameters of population differentiation and structure have been explored as well as selection signatures in the whole gene. Allele T, the common variant, shows extremely high values in Sub-Saharan African groups (frequencies 86–91%) as compared with the remaining world regions (69–49%). TT genotype also predominates in African groups, showing significant differences with the rest of world populations. In view of the evidence that the TT genotype is associated with clinical implications and a better predisposition to sprint/power performances, we suggest that the high presence of the TT genotype in African populations should be taken into account in future association studies at both medical and sports fields.  相似文献
