The impact of oral training on argumentative texts produced by ten-and eleven-year-old children: Exploring the relation between narration and argumentation

10 and 11-year old children were trained to improve their argumentative abilities. Tests were performed on two experimental groups to find out the effects of (1) a didactic sequence of seven lesson with oral exercises, and (2) a co-operative oral debate. To allow us to determine the improvements, the children had to produce three argumentative constrained texts (Alpha-Omega), before and after each phase of training. We compare the results with two control classes to try to determine the quality of transfer between the teaching periods. The qualitative analysis of the texts allows us to identify certain linguistic indicators of the underlying cognitive processes. The results show an effect of training only for the 11-year-old writers. In the 10-year-old children, no clear transfer from oral training was observed. With or without training, ten-year-old writers seem to have difficulties organising the text and managing multiple constraints when writing. In contrast, at 11, the subjects reorganise their activity without taking account of their narrative abilities. The vast majority produce better balanced argumentative texts. However their texts tend to be justificatory rather than negotiated. At the same time, the Alpha-Omega task carries very strong constraints which interfere with cognitive processes during on-line production.     

Paulo Freire,Critical Literacy,and Indigenous Resistance

Using several case studies drawn from Freire’s cultural context and contemporary Canadian Indigenous resistance movements, this article questions whether a Freirean approach to critical literacy can work with Indigenous literacy needs without reproducing colonial power structures. It also seeks to examine current scholarship in the literacy education of Maritime Aboriginal people in Canada and to illustrate the need for critical pedagogies honoring multiple cultural literacies and ways of knowing among Indigenous youth.     

Identifying high-functioning dyslexics: is self-report of early reading problems enough?

We used a questionnaire to identify university students with self-reported difficulties in reading acquisition during elementary school (self-report; n=31). The performance of the self-report group on standardized measures of word and non-word reading and fluency, passage comprehension and reading rate, and phonological awareness was compared to that of two other groups of university students: one with a recent diagnosis (diagnosed; n=20) and one with no self-reported reading acquisition problems (comparison group; n=33). The comparison group outperformed both groups with a history of reading difficulties (self-report and diagnosed) on almost all measures. The self-report and diagnosed groups performed similarly on most tasks, with the exception of untimed reading comprehension (better performance for diagnosed) and reading rate (better performance for self-report). The two recruitment methods likely sample from the same underlying population but identify individuals with different adaptive strategies.     

The time course of the syllable frequency effect in visual word recognition: evidence for both facilitatory and inhibitory effects in French

The present study tracked the time course of the syllable frequency effect in French visual word recognition, by varying the strength of spreading activation between letters and phonological syllables. The frequency of phonological first syllables and the frequency of orthographic first syllables were conjointly manipulated in two lexical decision tasks. In Experiment 1, word parsing into syllable units was supported by orthographic redundancy. No interaction between orthographic and phonological syllable frequency was found. In Experiment 2, word parsing into syllables was not marked by orthographic redundancy. Results showed an interaction between orthographic and phonological syllable frequency: the syllable frequency effect was inhibitory when orthographic syllable frequency was high, whereas it was facilitatory when orthographic syllable frequency was low. Decreasing the strength of syllable activation (i.e., with orthographic syllables of low frequency and ambiguous syllable boundaries) prevented the activation of lexical competitors before target word recognition, leading to a facilitatory effect of syllable frequency. The present study provides evidence that the net effect of syllable frequency is strongly related to its time course, and that the strength of syllable activation, which depends on orthographic properties, determines the direction of the net effect.     

Convergence of Visions

The right for everyone to access “the promised land” of the InfoSociety is widely recognized. The “wiring of the universe” is now technically and financially possible. One should do it quickly in the respect of human values and rights, freedom of opinion, transparency and cultural diversity. However, in the context of communication developments in 1997, it is a multifacet issue of concern to all the countries. The cyberspace era brings many new challenges to the communications' academic curricula, professional practices, media owners and the research and development (R&D) of industries across the world. The emerging virtual communities change social and political relationships, as well as the job market well beyond national and linguistic boundaries. The paper examines the minimal conditions needed for this open process to take place with the participation of all players and the possible role of ORBICOM, the network of UNESCO Chairs in Communication.     

Conceptions of first‐year university students of the constituents of matter and the notions of acids and bases

Preconceptions of first‐year university students of the constituents of matter and the notions of acids and bases were investigated on a total of 400 students. The procedure used consisted of free interviews, semi‐structured interviews and questionnaires.

It was found that the constituents of matter were well known to students, but that interactions between these constituents were either totally unknown or were the subject of severe misconceptions. The students’ knowledge tended to be qualitative and formal, with a worrying lack of connection with everyday life.     

Psicología cognitiva y educación

RESUMEN

Este artículo es un intento de acercar la psicología experimental cognitiva a la práctica educativa. La gran distancia que separa a ambas se debe tanto a la falta de validez ecológica de muchas investigaciones como a la novedad y complejidad de este modelo. Sin embargo, los métodos de análisis elaborados por los psicólogos cognitivos pueden contribuir a mejorar los métodos de enseñanza. Por ejemplo, los enfoques procesuales nos hacen comprender los mecanismos implicados en algunos saberes escolares, como en las matemáticas. Pero también plantean algunos problemas, ya que son muy sensibles a las variaciones del contexto y poco explícitos con respecto a los mecanismos de cambio de los procesos. Por ello, hay que completar los enfoques procesuales con enfoques estructurales, como el desarrollado por Piaget, que establece la génesis y el desarrollo de las estructuras de las acciones y las operaciones del sujeto y que propone la llamada pedagogía operatoria, que se concreta en la utilización de métodos activos de educación.     

La Psicología de Vygotski: sobre la larga proyección de una corta biografía

RESUMEN

Se presenta el contexto histórico y los antecedentes familiares, culturales y sociales en los que surge la figura de Vygotski y se hace una descripción minuciosa de su obra, de sus implicaciones y contribuciones a la Psicología Científica: su teoría sobre las funciones superiores en el hombre, la actividad instrumental como unidad de análisis de estos procesos superiores, los estudios sobre génesis y desarrollo de los procesos cognitivos y las variaciones culturales, la “zona de desarrollo potencial”, sus aportaciones a la pedagogía y al estudio de las deficiencias, su teoría de la organización neurofisiológica, sus aportaciones a una teoría general del desarrollo y su teoría de la génesis del pensamiento verbal y la función reguladora del lenguaje. Se citan algunas críticas a Vygotski y se formulan algunas implicaciones teóricas no formuladas explícitamente en su teoría.     

Quality assessment in diverse disciplinary settings

Basic work in universities is carried out in departments representing diverse disciplinary communities. While tasks, goals, perspectives, and social values may vary considerably between different disciplines, it is difficult to find research texts dealing with the question whether, and how, such differences should be taken into account in quality management. The paper is based on a recent study on quality management in diverse disciplinary settings, in which thirty-three interviews have been carried out in Finland and in the UK, and on the author's previous studies on the disciplines under study. The paper provides some preliminary interpretations of the effects of basic disciplinary features on the suitability of approaches of quality assessment in four diverse disciplines (physics, biology, sociology and history).
