Sociomathematical and mathematical norms related to definition in pre-service primary teachers’ discourse

This study is part of a wider research program, which seeks to investigate the existence (or not) of relationships between sociomathematical and mathematical norms at different academic levels. Here, we consider the norms that arise in the interaction between primary student teachers when they solve a mathematical task related to the mathematical definition. We hypothesize that in the colloquial mathematical discourse between these students coexist two types of discourse as follows: sociomathematical and mathematical, each one with its specific norms. This coexistence can originate commognitive conflicts. We have been able to identify different commognitive conflicts that arose from the simultaneous existence of sociomathematical norms and mathematical norms linked to defining, approaching their generation.

The titles included are a selective and representative sampling. The entry for each periodical includes the following information: periodical title, publisher/editor and address, basic information, publication data, content, Internet information, and an abstract/annotation.     

An analytical framework for analyzing student teachers’ verbal interaction in learning situations

This paper focuses on the study of student teachers’ verbal interaction in learning situations generated in a classroom corresponding to a mathematics methods course. In our work, we incorporate two ‘ways of seeing’ a group: as an entity or as a set composed of individualities. We present an analytical framework that considers two dimensions connected with these ways of seeing the group and four variables corresponding to these dimensions, through which the verbal interaction between student teachers in a group can be considered. As regards the first dimension, the variables included are specific language, cognitive processing, social processing; the second dimension considers the relational variable. We describe each of the different variables that form the framework, and how this framework allows us to analyse the verbal interaction in three groups of student teachers. We believe that building analytic frameworks that allow the study of verbal interaction in detail is worthwhile in the educational field due to their important role in the analysis of learning-teaching processes.     

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.     

Reflexiones sobre el lenguaje autista. I.—Análisis descrpitivos y diferencias con la disfasia receptiva

Resumen

En este articulo, se revisan las descripciones clínicas y los estudios sistemáticos que tratan de establecer los rasgos que definen al lenguaje de los autistas cuando se les compara con el dé los sujetos normales o con otras clases de alteraciones. En la última parte de él, se analizan especialmente las semejanzas y diferencias entre el lenguaje autista y el de los niños con disfasia receptiva del desarrollo y anlizaremos la llamada «tesis de continuidad», que concibe el autismo como una especie de disfasia receptiva grave. En un trabajo posterior, se analizarán más específicamente algunas de las alteraciones más características del lenguaje de los autistas (p.e. ecolalia, inversión pronominal, problemas de comprensión) y se discutirán sus anomalías y retrasos en relación con los distintos componentes (fonológico, morfosintáctico, léxico, etc.) en que puede analizarse el lenguaje.     

Déficits socioculturales en niños de educación especial. Elaboración experimental de un programa de rehabilitación

Resumen

La experiencia realizada en las aulas de Educación Especial en la ciudad de Jaén pone de relieve los problemas educativos que plantean las mismas. Presentamos un tratamiento rehabilitador aplicado a un grupo de niños de educación especial y se contrastan los resultados con otros dos grupos que no reciben directamente el programa. Los resultados obtenidos revelan la efectividad del tratamiento y la inadecuación del actual sistema de aulas de Educación Especial en el contexto escolar. Se discuten y analizan los factores implicados y se ofrece evidencia experimental de los mismos. A partir de los resultados se extrae una serie de consecuencias de interés, sobre todo de cara a la aplicación educativa.     

Reliability and validity evidence of scores on the Achievement Goal Tendencies Questionnaire in a sample of Spanish students of compulsory secondary education

This study examined the reliability and validity evidence drawn from the scores of the Spanish version of the Achievement Goal Tendencies Questionnaire (AGTQ) using a sample of 2,022 (51.1% boys) Spanish students from grades 7 to 10. Confirmatory factor analysis replicated the correlated three‐factor structure of the AGTQ in this sample: Learning Goals (LG), Social Reinforcement Goals (SRG), and Performance Goals (PG). The AGTQ yields relatively reliable scores for Spanish students. Logistic regression analyses were used to provide additional validity evidence of AGTQ scores on academic success (general, Spanish, and mathematics). Results indicated that general academic success was 15% and 5% more likely every time that scores on LG and PG scales increased 1 point, respectively, although general academic success was 9% less likely every time that scores on SRG scale increased 1 point. These results were similar for Spanish and mathematics. However, the score on the LG scale did not forecast success in both subjects. © 2009 Wiley Periodicals, Inc.     

Intellectual property rights,trade agreements,and international trade

The global process of strengthening and harmonization of intellectual property rights (IPRs) systems has been intensified in the last twenty five years by the signing of trade agreements (TAs) that include chapters with intellectual property (IP) provisions and other trade-related issues. This paper provides a first exploration of whether and how the signing of TAs with IP chapters influences bilateral trade flows for a balanced panel of 110 countries and the period 1995–2013. We address methodological issues related to the assessment of the effect of TAs on bilateral trade. We use matching econometrics to evaluate the treatment of TAs with and without IP chapters. In addition, we estimate the effects of TAs on bilateral trade in a more dynamic fashion using a panel data approach based on the gravity model. Also, we perform our analysis for trade in low- and high-IP intensive products. We found that both types of TAs increase bilateral trade but TAs with no IPRs chapters have a stronger positive effect on trade. However, if we include lags to consider that TAs with IP chapters might need a longer implementation time, the net expected increase on trade is similar for both types of TAs. We also found that the effects depend on the development level of countries and on the IP intensity of products. We found a clear positive effect for developed countries, but we do not observe important gains for developing countries in all sectors and to all destinations derived from TAs with IP chapters. This raises the question of whether trade gains can compensate the effort related with IP reforms.     

Checking the underlying structure of R-SPQ-2F using covariance structure analysis / Comprobación de la estructura subyacente del R-SPQ-2F mediante análisis de estructura de covarianza

The R-SPQ-2F is an instrument used in many studies to measure learning approaches. However, its internal structure is still a matter of debate. It is important to confirm its underlying structure in order to find out which variables are being measured with it. A survey method is used with 279 students of the Faculty of Education at the University of León, and alternative models found in the literature are compared using covariance structure analysis, specifically, Confirmatory Factor Analysis (CFA). We conclude that the structure that best fits the data is a two-factor structure in line with the results obtained in other studies. Future research should take these two primary factors into account when interpreting their findings. Solutions are also offered for improving the scale with the original 20 items.
