Segmental awareness and dyslexia: Is it possible to learn to segment well and yet continue to read and write poorly?

This study is focused on the relationship between the development of segmental awareness and dyslexia. More specifically we have tried to address the question, is it possible to learn to segment well and yet continue to read and write poorly? For this purpose, 14 second and third grade dyslexic children were assigned to three different training programs. Those who participated in the first two programs were taught the skills required to use the phonemes, while those in the third program, who served as a pseudo-control group, were given the exercises in perceptual and psychomotor activities. After the training program, children who had received the first two training programs reached a level of performance similar to that of normal readers in different tasks of segmentation of phonemes. The improvements observed in these tasks were correlated in dictation but not in reading, where there was no difference after training.     

Assessment of collaborative learning experiences by graphical analysis of wiki contributions

The widespread adoption of computers and Internet in our life has reached the classrooms, where computer-supported collaborative learning (CSCL) based on wikis offers new ways of collaboration and encourages student participation. When the number of contributions from students increases, traditional assessment procedures of e-learning settings suffer from scalability problems. In a wiki-based learning experience, automatic tools are required to support the assessment of such huge amounts of data. In this work, we present StatMediaWiki, a tool that collects and aggregates information that helps to analyze a MediaWiki installation. It generates charts, tables and different statistics enabling easy analysis of wiki evolution. We have used StatMediaWiki in a Higher Education course and present the results obtained in this case study.     

Creation of an integrated environment to supply e-learning platforms with Office Automation features

Over the last years great efforts have been made within the University environment to implement e-learning technologies in the standard educational practice. These learning technologies distribute online educational multimedia contents through technological platforms. Even though specific e-learning tools for technical disciplines were already available on the Internet, in our opinion more general tools, typically involving calculations, plots or diagrams, through the use of spreadsheets or graphical applications, were still needed to provide a more flexible and multi-purpose integrated environment. Therefore, we developed an integrated system to supply e-learning platforms with almost the same functionalities offered by standalone Office Automation applications. Modular object-oriented dynamic learning environment (MOODLE) and OpenOffice.org were selected to deal with any problem originating from the software and to smooth over the users' learning curve. Furthermore, MOODLE is a modular platform and offers an extensive application programming interface for coding in a simple and effective manner. The implementation of the work required the employment of Java and Asynchronous JavaScript and Extensible Markup Language technologies and included the creation of a Java Applet to be embedded in the web pages of the new MOODLE modules. Students could thus be offered a single working environment for handling “traditional” material and performing practical activities. The students' feedback on this new integrated system was very positive and proved the effectiveness of our work.     

Cómo mejorar la comprensión de textos en el aula

¿Qué ocurre cuando un niño comprende o no comprende? ¿Cómo se explica psicológicamente el proceso de comprensión de un texto? Después de aportar una base a ese nivel, el autor construye sobre ella en este artículo un programa de instrucción para mejorar las habilidades de comprensión y un método de evaluación de esas habilidades.     

Teachers’ scaffolding science reading comprehension in low-income schools: how to improve achievement in science

ABSTRACT

Reading is a tool that promotes the learning of science across schooling. Scientific texts are conceptually and linguistically complex, especially for students from low-income contexts because they have neither the experience with the language nor the literacy skills to face the challenges of scientific knowledge. This study used a mix method approach to compare the cognitive scaffolding practiced by teachers during science reading activities in high- and low-performing schools. Three teachers and 141 fourth grade students from low socioeconomic background schools participated in 48 class sessions. Classes were video-recorded and transcribed. The data were analyzed using Sanchez’ Pedagogic Practice Analysis System. The results show that teachers from both types of schools continuously use reading as a tool for learning. The effective teacher uses reading with non-invasive scaffolding and varied verbal participation to elaborate knowledge, promoting literal and inferential comprehension and more opportunities for the students to construct knowledge. By contrast, less effective teachers use reading with invasive scaffolding and little verbal participation of the students to consolidate knowledge, promoting mainly literal comprehension. This study shed light on different approaches teachers use to foster reading comprehension for science learning.     

El análisis de la palabra como instrumento para la rehabilitación de la dyslexia

Resumen

El objetivo de este trabajo ha sido diseñar y comprobar empíricamente el efecto que tiene una Instrucción en Habilidades de Análisis de la palabra sobre la mejora en el aprendizaje lecto-escritor de niños disléxicos. Los resultados obtenidos muestran que la instrucción produce una mejora significativa en la escritura al dictado de frases sueltas y en el dictado de textos. Los entrenamientos favorecieron la adquisición del metalenguaje (tareas de inversiones, adiciones, omisiones). Y no se alcanzaron resultados satisfactorios en el nivel de lectura de los niños con ninguno de los tipos de instrucciones.     

Egocentrismo espacial: concepto y procesos implicados

Resumen

En este artículo se estudia el concepto de egocentrismo espacial en una muestra de 47 niños entre 4 y 13 años, a través de un diseño transversal. Los resultados demuestran que los niños tienen capacidad de ponerse en el punto de vista del observador desde el período preescolar. Por otra parte, la capacidad de construir otras perspectivas con varios objetos, teniendo en cuenta las relaciones entre ellos, comienza a desarrollarse a partir de los 6 años en estrecha relación con la edad y el nivel de desarrollo.     

Ranking journals: could Google Scholar Metrics be an alternative to Journal Citation Reports and Scimago Journal Rank?

The launch of Google Scholar Metrics as a tool for assessing scientific journals may be serious competition for Thomson Reuters' Journal Citation Reports, and for the Scopus‐powered Scimago Journal Rank. A review of these bibliometric journal evaluation products is performed. We compare their main characteristics from different approaches: coverage, indexing policies, search and visualization, bibliometric indicators, results analysis options, economic cost, and differences in their ranking of journals. Despite its shortcomings, Google Scholar Metrics is a helpful tool for authors and editors in identifying core journals. As an increasingly useful tool for ranking scientific journals, it may also challenge established journals products.
