Segmentación fonológico-silábica y adquisición de la lectura: un estudio empírico

El artículo presenta una investigación cuyos resultados muestran la menor capacidad de segmentación silábica entre aquellos niños con peor habilidad lectora. Plantea también la funcionalidad, facilidad de aplicación y carácter motivador de la prueba realizada—una tarea de ordenador—para evaluar la capacidad de segmentación.     

The Politics of Playing Along: Radio and Regulation in Democratic Europe

The loss of localism has been a common trend in most radio markets in Europe and the United States. Deregulation of ownership led to a concentration phenomenon that has affected local radios in several western democracies. New forms of regulation have been considered as possible ways to stop the erosion of localism by applying rules to markets in the defense of diversity, pluralism, and the local dimension. This article analyses the local radio market in Portugal, by assessing the changes in the legislation and by examining the regulatory action that can, according to its remit, act preventively to avoid market forces to harm these principles.     

Environmental education in action: a discursive approach to curriculum design

Why do the designers of environmental education do what they do towards the environment through education? More importantly, how do they account for their design decisions (plans and actions)? Using the theoretical and methodological framework of discourse analysis, we analyse environmental education designers' discourse in terms of the discursive resources—or interpretive repertoires—that they use to (a) make their position, (b) make their talk do work and (c) tell a story about events, situations and who they are (identity). Drawing on observations and interviews from a larger programme concerned with understanding environmentalism and environmental education, we identified five main repertoires: relevance, knowledge transferability and translatability, emotionality, expertise and empiricism. The approach provides us with a more refined characterization of the culture of environmental education curriculum design through the ways designers in the field explain their doings, and we explore the important implications for curriculum design in this field.     

Regulation and Quality Assurance in Transnational Education

A huge array of new providers oftransnational higher education is proliferatingaround the world, almost outside any forms ofregulation or quality control, raising manyconcerns on consumer protection. The paperprovides a conceptual framework regarding basicdefinitions and a mapping of developments inEurope concerning the situation and trends oftransnational education, the regulatorymechanisms in place or under consideration, theproblems arising and examples of good practicein dealing with them. In particular, thecrucial issues of regulation, quality assuranceand recognition of transnational education areaddressed, and some basis for an action planare recommended.     

Reading in examination‐type situations: the effects of text layout on performance

Examinations are conventionally used to measure candidates' achievement in a limited time period. However, the influence of text layout on performance may compromise the construct validity of the examination. An experimental study looked at the effects of the text layout on the speed and accuracy of a reading task in an examination‐type situation. A survey of the reading strategies used in examinations was conducted to help in defining the reading context in which text layout may have an effect. A set of guidelines was also derived from research on typographic features of text and these were used to select three text layouts (intended to be more or less legible) from the layouts used in English language reading examinations. Results of the experiment showed that task time was significantly shorter and the number of correct answers per second was significantly higher with the layout conforming to legibility guidelines. Participants' judgements indicated that this layout was also the easiest in which to find answers and the most attractive. The main conclusion of the study is that text layout affects performance in a task that involves reading text to search for specific information in order to answer questions on it under time pressure. Consequently, the construct validity of examinations may be compromised by confounding legibility with reading skills.     

Innovative Training of In-service Teachers for Active Learning: A Short Teacher Development Course Based on Physics Education Research

In this contribution we describe a short development course for in-service physics teachers. The course structure and materials are based on the results of educational research, and its main objective is to provide in-service teachers with a first contact with the active learning strategy “Tutorials in Introductory Physics,” developed by the Physics Education Research Group at the University of Washington. The course was organized in a constructivist, active learning environment, so that teachers have first to experience, as regular students, the whole Tutorial sequence of activities: Tutorial pre-test, Tutorial, and Tutorial Homework. After each Tutorial, teachers reflect on, and recognize their own students’ learning difficulties, discussing their teaching experiences with their colleagues in small collaborative groups first and the whole class later. Finally they read and discuss specific Physics Education Research literature, where these learning difficulties have been extensively studied by researchers. At the beginning and at the end of the course the participants were given the conceptual multiple-choice test Force Concept Inventory (FCI). The pre-/post-instruction FCI data were presented as a practical example of the use of a research-based test widely used in educational research and in formative assessment processes designed to improve instruction.

Effects of adding a weekly eccentric-overload training session on strength and athletic performance in team-handball players

To investigate the influence of adding a weekly eccentric-overload training (EOT) session in several athletic performance’s tests, 18 team-handball players were assigned either to an EOT (n?=?11) or a Control (n?=?7) group. Both groups continued to perform the same habitual strength training, but the EOT group added one session/week during a 7-week training programme consisting of four sets of eight repetitions for the bilateral half-squat and unilateral lunge exercises. The test battery included handball throwing velocity, maximum dynamic strength (1RM), countermovement jump (CMJ), 20?m sprint, triple hop for distance, and eccentric/concentric power in both the half-squat and lunge exercises. Data were analysed using magnitude-based inferences. Both groups improved their 1RM in the half squat, 20?m sprint time, and CMJ performance to a similar extent, but the EOT group showed a beneficial effect for both right [(42/58/0), possibly positive] and left [(99/1/0), very likely positive] triple hop for distance performance. In addition, the EOT group showed greater power output improvements in both eccentric and concentric phases of the half-squat (difference in percent of change ranging from 6.5% to 22.0%) and lunge exercises (difference in per cent of change ranging from 13.1% to 24.9%). Nevertheless, no group showed changes in handball throwing velocity. Selected variables related to team-handball performance (i.e. functional jumping performance, power output) can be improved by adding a single EOT session per week, highlighting the usefulness of this low-volume/high-intensity training when aiming at optimizing dynamic athletic performance.
