RESUMEN
Resumen Introducción: La lectura dialógica es una de las técnicas más empleadas y estudiadas en el marco de las actividades de lectura compartida de libros entre niños y adultos. La presente revisión siste mática tiene como objetivo principal analizar sus efectos en el lenguaje de niños hablantes tardíos o con trastorno del desarrollo del lenguaje, no asociados a otra condición. Métodos: Se llevó a cabo una revisión sistemática de la literatura siguiendo las orientaciones del PRISMA Statement, mediante la consulta con diferentes bases de datos. Resultados: Las investigaciones revisadas muestran progresos en el lenguaje de los niños en indicadores léxicos, gramaticales y pragmáticos. También se observan cambios en el lenguaje de los adultos que aplican la intervención, tanto en el uso de las estrategias propias de la técnica como en las características gramaticales y suprasegmentales de su lenguaje. Discusión: La evidencia sobre la efectividad de la lectura dialógica en niños con trastornos del desarrollo lenguaje es prometedora pero presenta limitaciones importantes relativas, funda mentalmente, al diseño, la validez social y la fiabilidad de las intervenciones. Otras cuestiones destacables hacen referencia a los libros o materiales con los que se interactúa y a las medidas empleadas para valorar su efectividad.
Abstract Introduction: Dialogic reading is one of the most used and studied techniques within the fra me of shared book reading activities between children and adults. The current review aims to analyze its effects in late talkers and children with developmental language disorder, that is, not associated to other condition. Methods: A systematic review of the literature was carried out following PRISMA Statement gui delines. Results: The investigations reviewed show advances in children's lexical, grammatical and pragma tic indicators of language functioning. Likewise, changes are observed in the language of adults who apply the intervention, both in the use of dialogic reading strategies and in the grammatical and suprasegmental features of the language addressed to children. Discussion: The evidence about the effectivity of dialogic reading in late talkers and children with developmental language disorders is promising but has important limitations that are mainly related to the design, social validity and reliability of interventions. Other remarka ble issues relate to the books or materials employed and the measures used to assess its effectiveness.
RESUMEN
Resumen Existe consenso en la literatura acerca de la importancia del andamiaje del adulto en el desarrollo de la cognición y, particularmente, de las habilidades lingüísticas de los niños (Bruner, 1986; Nelson, 1996; Vygotsky, 1978). En este sentido, el presente trabajo tuvo por objetivo examinar la incidencia de la intervención del adulto, según su metodología de enseñanza, en el desempeño narrativo de niños de primer grado. Para ello, se evaluó el rendimiento en una tarea de recuento de relatos de dos grupos de niños que concurrían a primer grado en escuelas del distrito de Quito que sostenían una metodología diferente: mientras que una de ellas se atenía exclusivamente a los lineamientos del diseño curricular planteado por el Ministerio de Educación, en la otra se incorporaban, además, estrategias de los libros Letras y sonidos I (Jara de Torres, 2001) y Aprendo y escribo (Jara de Torres, 2003) -adaptados de la propuesta integral de la editorial Abeka- y principalmente se recurría a la lectura dialógica y a la enseñanza explícita de habilidades de producción de relatos. Se analizaron las narrativas producidas por los niños a principio y a fin de año y se comparó el desempeño de ambos grupos atendiendo tanto a la cantidad de información recuperada como al tipo de información y los recursos lingüísticos puestos en juego. Se observaron diferencias significativas en las variables mencionadas, lo cual brinda evidencia acerca de la incidencia positiva de la lectura dialógica y la enseñanza de habilidades de producción de relatos en el desarrollo narrativo.
Abstract There is a consensus in the literature about the importance of adult scaffolding in the development of children's cognition and language skills (Bruner, 1986; Nelson, 1996; Vygotsky, 1978). This document analyzes first grade children's narrative development in order to verify the incidence of adult intervention and teaching methodology. For this purpose, the performance of two groups of children enrolled in first grade of school in the district of Quito was analyzed. Two different teaching methodologies were observed: while one of them exclusively adheres to the guidelines of the curriculum design proposed by the Ministry of Education, the other one incorporates strategies from the books Letters and Sounds I (Jara de Torres, 2001) and Learn and Write I (Jara de Torres, 2003) -adapted from the proposal by editorial Abeka. The narratives performed by the children at the beginning and at the end of the school year were analyzed and each performance of both groups was compared based on the amount of information retrieved and the type of information and linguistic resources used. The stories were presented to the children in audiovisual format (steady images and recorded voice). For task administration, the children were instructed to listen and look at the story very carefully because they had to recount it to a friend or family member. The children's remarks were recorded on audio for later analysis. Descriptive and inferential statistical methods were used in order to analyze and compare the linguistic and cognitive performance in the production of stories of the two groups of children in the different evaluation. Significant differences were observed in the variables analyzed, which provides evidence about the positive incidence of dialogic reading and the teaching of story production skills in narrative development. Differences in the performance of schools, especially in first graders, cannot be attributed to maturational factors since both groups are conformed by children of the same chronological age. Neither by the socioeconomic factors, since, in fact, group A was composed of children who attend a rural school and most of them happened to have low resources. Therefore, the significant improvement in the performance of the children of group A at the end of the school year could be attributed to the intervention of their teacher's work. It is thought that this advance in retell story skills is due to an improvement in the understanding of the basic story, however there are studies that observe that the level reached in this process does not directly affect the quality of children's narrative performance (Bustos Ibarra et al., 2014). In consequence, the improvement in the children's narrative performance of group A can be linked not only to the work carried out by the teachers with texts but also to the situations of story production involved. Many investigations have observed that adult scaffolding during story reading has a positive effect on children's linguistic and discursive development (Sénechal, Le Fevre, Hudson & Lawson, 1996; Trabasso & Nickels, 1992; Wasik & Bond, 2001; West et al., 2021). In fact, as Wells (1988) points out in a pioneering study, while reading stories contributes to children's linguistic development, the parallel text generated by teachers through their interventions to explain vocabulary, make inferences explicit, relate events and post-reading reconstruction has shown a greater effect than just reading any kind of story aloud. Thereupon, the results obtained in this work show the relevance not only of the teacher's texts daily reading but, mainly, of the intervention strategies and methodologies that they use to promote comprehension and textual production in the classroom.
