Emergence of Global Shape Processing Continues Through Adolescence

The developmental trajectory of perceptual organization in humans is unclear. This study investigated perceptual grouping abilities across a wide age range (8–30 years) using a classic compound letter global/local (GL) task and a more fine-grained microgenetic prime paradigm (MPP) with both few- and many-element hierarchical displays. In the GL task, contrary to adults, both children and adolescents exhibited a classic local bias. In the MPP, all 3 age groups evinced a bias to individuate the few-element displays; however, the ability to encode the global shape of the many-element displays at the short prime durations increased with age. These results indicate that the full process of garnering shape information from perceptual grouping, which is essential for the ability to do fast and efficient object recognition and identification, develops late into adolescence.     

The (in)visibility of gender knowledge in the Physical Activity and Sport Science degree in Spain

This paper draws on research that aimed to explore the construction of gender relations in sport and physical education (PE) through a national study of Spanish university degree curricula. Spain is a useful case study through which to explore gender knowledge within sport and PE degrees, because, unlike many other countries, it has a common, national curriculum framework for its Physical Activity and Sport Science (PASS) degrees. In addition, it has recently passed a new law concerning the introduction of gender knowledge in higher education (HE). Drawing on Bernstein’s (1990) framework of the pedagogic device, this paper examines how this HE gender policy becomes recontextualised as universities and lecturers interpret and translate this into the pedagogical texts that make up the PASS curricula. Purposive sampling was used to select 16 of the 37 universities offering PASS degrees in 2012/2013. The research analysed 16 PASS documents at the degree level and 763 individual subject handbooks. Using discourse analysis, the results showed where and how gender knowledge was incorporated and the extent to which the topic was presented coherently throughout the documents. The analysis revealed five categories of the (in)visibility of gender knowledge within the universities’ instructional discourse. Gender knowledge is largely ignored in PASS curricular documentation, appearing, at best, in highly superficial ways. Despite a national policy requirement on universities to incorporate gender knowledge, this study shows how recontextualisation processes within specific universities’ pedagogic devices operate to marginalise such perspectives within PASS curricula. The research also revealed the significance of individual agents committed to gender equity being situated, and having influence, throughout the pedagogic device. The paper concludes that without a much wider, critical engagement in knowledge about gender equity, PASS degrees will continue to reproduce rather than disrupt the gender relations that have traditionally characterised the field.     

Bulding ambidexterity through creativity mechanisms: Contextual drivers of innovation success

Do creativity methods consistently produce a significant net effect on innovation? Are the impacts of creativity methods related to operating context? Based on an ambidexterity perspective, we examine the effectiveness of different creativity methods on overcoming the tensions of the innovation process at individual and team levels. Drawing on European Union Community Innovation Survey (CIS2010) data collected from 23,537 firms, we estimate causal effects of creativity on innovation through a multivalued treatment effect methodology. Our results show that implementing ambidexterity in creativity methods increases the firm´s propensity to innovate and to introduce a market novelty. However, the effect on firm turnover is not always clear. Also, we detect that ambidexterity is more effective in firms that are large in size, have high levels of R&D investment and operate in manufacturing sectors. We discuss the implications of these findings for practice and for future research.     

XML markup and information retrieval in magazine articles: Exploratory results and implementation issues

This paper relates to the difficulty in retrieving precise information from big repositories of magazine articles in full text, and proposes an Extended Markup Language (XML) vocabulary for improving retrieval rates. The hypothesis tested was as follows: Magazine articles marked up with an XML vocabulary, indexed only by selected parts, give more precise search results than the same search using full text index.The study was exploratory with the following characteristics: 29 magazine articles were tested for results, 8 scholars were interviewed for defining 23 search strategies and evaluating results. The data showed that precision improved from 40.72% with full text search to 62.84% using XML markup and searching only in specific labels.Revision of the vocabulary and more testing has to be done by the library and information science community in order to obtain a valid vocabulary and provide more research results. Cultural characteristics and politics of librarians and information managers’ community are as important as technical issues in order to consider any technical proposal to be implemented successfully to achieve interoperability.     

A literature review of school leadership policy reforms

This literature review aims to understand the factors that influence the adoption of school leadership policy reforms and whether there are some common trends that lead to policy changes in this area. The main question driving the study was the following: what are important reasons or contextual factors that have influenced the adoption of school leadership policy reforms? The analysis shows that there is an eclectic set of research that covers school leadership from different perspectives. Each tackle the question of school leadership reform adoption from different angles. A policy perspective associates school leadership reforms to contextual changes in relation to decentralisation, school autonomy, accountability or an increasing emphasis on education outcomes. School improvement perspectives acknowledge the key role of school leadership in education change. The research on school leadership impact has contributed to the adoption of school leadership reforms. The school leadership policy perspective shows that countries have introduced school leadership reforms, with practices varying by country and context. Some have been interpreted as a response to a new public management agenda or to the globalisation of education policies. Findings from this review indicate that whilst there is much research on school leadership, nevertheless, analysis and promotion of policies to support and strengthen school leader roles to support school improvement appears to have received less attention.     

Digital illiteracy: a challenge for 21st century teachers / El analfabetismo digital: un reto de los docentes del siglo XXI

Resumen

El aprendizaje de la química requiere dominar los diferentes códigos mediante los que se representa gráficamente la organización espacial de las moléculas. Los alumnos deben no sólo aprender la nomenclatura de esos sistemas de representación, sino también sus reglas sintácticas, siendo capaces de traducir de un código o lenguaje a otro, y de decidir cuándo y con qué metas deben usar cada uno de esos sistemas de representación. Para investigar cómo proceden y qué dificultades tienen estudiantes universitarios de química para usar esos sistemas de representación realizamos dos estudios. En total participaron 201 estudiantes universitarios, 174 estudiantes argentinos de un primer curso de química orgánica y 27 estudiantes españoles de la carrera de Psicología, que respondieron a tareas escritas diseñadas específicamente para esta investigación.

Los resultados mostraron que en general los estudiantes de química utilizan los diferentes sistemas de representación de forma adecuada. Sin embargo, aunque son eficaces en los procesos de traducción, no lo son en cuanto a su uso estratégico dependiente del marco teórico-conceptual. Por otra parte, al presentarles en el segundo estudio una tarea sin contenido químico, pero gráficamente isomorfa a las tareas químicas, los estudiantes de química, a diferencia de los de psicología, cometían errores característicos como consecuencia de interpretar el problema con una tarea dentro de un sistema representacional químico. Se discuten también algunas de las implicaciones de los resultados para el aprendizaje y la enseñanza de la química en la universidad.     

Reasons which influence on the students’ decision to take a university course: differences by gender and degree

After compulsory secondary education; many teenagers face the process of choosing a university degree. This process involves uncertainties referred to their personal abilities, interests, social expectations and professional future. The present work is aimed at determining whether the reasons behind the selection of a particular university degree differ depending on the chosen degree. Another objective is determining whether these reasons differ significantly according to gender. The sample comprises 983 students belonging to the area of social and legal sciences at the University of Seville. The obtained results reveal the existence of four main reasons behind the selection of university degrees for which significant gender-related differences were observed: easy degree, job opportunities, high wages and provision of social services. Besides, these seven reasons are observed to differ widely in six of the considered degrees.     

Las concepciones de los padres sobre el desarrollo: Teorías personales o teorías culturales

Resumen

Este artículo ofrece un modelo teórico para explicar el origen de las concepciones de los padres sobre la educación y el desarrollo, y cómo éstas se plasman en la mente de los padres. Se postula que la cultura ofrece un amplio bagaje de concepciones que se transmiten mediante las interacciones que establecen los sujetos en los contextos sociales próximos. No obstante, el papel de la cultura queda regulado por los mecanismos de elaborarcíón de la información que caracterizan el procesamiento humano. Esto se demuestra al analizar, a partir de un conjunto de teorías de gran raigambre cultural, las mezclas coherentes de teorías que asumen los padres. Los objetivos que se persiguen son: a) Elaborar un cuestionario para estudiar las teorías; y b) analizar el papel de los contextos sociales próximos en la selección de las teorías que asumen los padres, destacando el nivel educativo y profesional de los padres así como la zona donde residen, como variables determinantes del tipo de teoría/s que éstos seleccionan.     

El concepto de infancia en nuestra sociedad: una investigación sobre teorías implícitas de los padres

Resumen

Las teorías implícitas que mantienen los padres respecto a sus hijos recibieron un análisis empírico sistemático. Se seleccionaron varias teorías cuyo origen histórico es bien conocido: homúnculo, innatista, ambientalista, voluntarista, constructivista, médica y roussoniana. A partir de diversos estudios normativos se establecieron: a) el dominio de proposiciones de cada teoría; b) su tipicidady polaridad, y c) el grado de estabilidad de tales índices. De modo convergente, se utilizó una técnica cronométrica que halló una relación sistemática entre latencia de verificación, consistencia de juicios de verdad y tipicidad de las proposiciones. Por último, se comprobó la presencia y consistencia de las teorías implícitas en el sistema conceptual de los padres, observándose acusadas preferencias por las teorías constructivista, ambientalista y voluntarista.
