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.

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.     

Political persuasion on social media: A moderated moderation model of political discussion disagreement and civil reasoning

Abstract

Social media and news use arguably contribute to the prevalence of contentious politics because individuals may express dissent through their social networks as they consume news. This study seeks to test whether individuals might be more open to political persuasion in this context, especially if they are exposed to political disagreement or discuss politics in a civil manner. Relying on survey data from the UK, results based on a moderated moderation model show that (a) social media news use predicts political persuasion on social media (direct effects) and, (b) discussion disagreement and civil reasoning moderate this relationship in two-way and three-way interactions.     

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.     

New trends in science education

I intend to review the main contributions from the impressive developments made in science education research during the last decade. These developments have made the construction of a coherent body of knowledge possible allowing us to expect a significant improvement in the science teaching/learning process. I shall refer, in particular, to the new trends in science education research, both in the domain of science learning and science teacher‐training.     

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.     

A practical approach to making accurate 3D layouts of interesting cultural heritage sites through digital models

On many occasions, the graphic information handled by people working in the cultural heritage sector is still bidimensional. Layouts showing elevations and cross sections are the most widespread tools. However, there is an increased need for carefully detailing the complexity of valuable sites with an improved accuracy. This implies the measuring and handling of three-dimensional data, using both commercial and turn-key hardware and software solutions. Taking the usual traditional process as a reference, in the present paper a new effective methodology for carrying out computer assisted delineation of layouts from cultural heritage sites, using 3D digital models, is described. The proposed procedure has been tested in five intervention projects on representative churches within the “Merindad de Aguilar de Campoo” medieval area, in the north of Spain.¹ This area has the largest collection of Romanesque art in the world, and is currently under European Heritage Site and World Heritage Site declaration process by the UNESCO.     

What is it worth? An empirical investigation into attitudes towards education amongst youngsters following secondary education in Flanders

This paper argues that whereas the social relevance of attitudes towards education is commonly confined to their direct impact on educational aspirations or attainment, attitudes may also impact on educational success in a way similar to cultural capital. Survey data were used to assess the support for three different attitudes with respect to the perceived value of attending school among youngsters (n = 853) following secondary education in Flanders (the Dutch-speaking part of Belgium). The results revealed substantial differences according to the pupils’ cultural capital, time perspective, personal educational experiences and social mobility. These findings are taken as a starting point for a broader discussion about how attention to attitudes may enable us to account for the power struggles in which the educational field and the teaching profession are involved.
