Chatbot dialogic reading boosts comprehension for Chinese kindergarteners with higher language skills.

Dialogic reading promotes early language and literacy development, but high-quality interactions may be inaccessible to disadvantaged children. This study examined whether a chatbot could deliver dialogic reading support comparable to a human partner for Chinese kindergarteners. Using a 2 × 2 factorial design, 148 children (83 girls; Mage = 70.07 months, SD = 7.64) from less resourced families in Beijing, China, were randomly assigned to one of four conditions: dialogic or non-dialogic reading techniques with either a chatbot or human partner. The chatbot provided comparable dialogic support to the human partner, enhancing story comprehension and word learning. Critically, the chatbot's effect on story comprehension was moderated by children's language proficiency rather than age or reading ability. This demonstrates that chatbots can facilitate dialogic reading and highlights the importance of considering children's language skills when implementing chatbot dialogic interventions.

Neurobiological perspective on the development of executive functions.

Executive functions are a set of top-down cognitive processes necessary for emotional self-regulation and goal-directed behaviour supporting, among others, academic abilities. Premature infants are at high risk for subsequent cognitive, psychosocial, or behavioural problems even in the absence of medical complications and in spite of normal brain imaging. Given that this is a sensitive period of brain growth and maturation, these factors may place preterm infants at high risk for executive function dysfunction, disrupted long-term development, and lower academic achievements. Therefore, careful attention to interventions at this age is essential for intact executive functions and academic development.

How fathers' attachment security and education contribute to early child language skills above and beyond mothers: parent-child conversation under scrutiny.

Attachment (AQS) of 100 children aged 12 to 24 months was observed, with more than half of the fathers (and mothers) representing higher social status. Children's language comprehension and production were measured using the Bayley Scales for receptive (RLS) and expressive language skills (ELS). Spontaneous book reading conversations in father-child and mother-child dyads were coded from videotapes, capturing five modes of conversation derived from research on dialogic reading. Path modelling examined the association of these modes on children's RLS and ELS in concurrence with parental attachment and education. First time, significant effects of father-child attachment security on children's RLS were revealed (and confirmed for mother-child dyads). Fathers' impact on child language skills could be further explained through modes which inquire and imitate child responses which were related to RLS and ELS, respectively. Although mothers' modes of conversation were associated with the mother-child attachment relationship, the father-child conversations were not so but instead were associated with the father's educational background.

Dialogic reading vs screen exposure intervention is related to increased cognitive control in preschool-age children.

AIM: Shared reading leads to better language and executive functions. This study was designed to examine the effect of dialogic reading compared to screen-exposed intervention on executive functions using behavioural and electroencephalogram measures. METHODS: The effect of six weeks of dialogic reading intervention on executive functions was examined in 16 children (seven females, 61.73 months, SD 7.07, min-max 50-170) vs 16 children exposed to screen (six females, 64.31 months, SD 64.31, min-max 52-74) recruited through posted ads in daycares in the north of Israel. Behavioural and attention/inhibition electroencephalogram tasks were used to assess the effects of intervention. RESULTS: Comparisons using t-test showed that the dialogic reading group demonstrated higher executive functions and language scores vs the screen-exposed group. Greater accuracy rates, shorter reaction times and a smaller gap between P300 amplitudes were found for the dialogic reading group compared to the screen group for the electroencephalogram task. CONCLUSION: Dialogic reading intervention is related to improved executive functions and language abilities compared to screen-based story-telling. Parents and teachers should consider employing this method in preschool children as a facilitator for future academic abilities.

Shared reading quality assessment by parental report: preliminary validation of the DialogPR.

BACKGROUND: The American Academy of Pediatrics (AAP) recommends shared reading beginning as soon as possible after birth to promote healthy development. Shared reading quality can strongly influence outcomes, especially in children from low-SES households. Dialogic reading is a method developed to enhance verbal interactivity and engagement through book sharing, advocated by the AAP and clinic-based programs such as Reach Out and Read. There is no brief, validated, caregiver report measure of dialogic reading or shared reading quality currently available. METHODS: This cross-sectional study involved 49 healthy mother-child dyads (mean child age 4.5 yrs., SD = 0.6 yrs.) from 2 separate MRI-based studies. The DialogPR was administered by trained research coordinators following MRI, along with the READ subscale of the validated StimQ-P measure of home cognitive environment. The DialogPR consists of eight items developed in consultation with experts in early literacy, based on the PEER/CROWD dialogic reading conceptual model. Estimated reading level is 6th grade. Descriptive statistics were computed at both the item and scale levels. Modern theory Rasch methods were used to analyze all eight DialogPR items along with preliminary estimates of reliability and validity. RESULTS: Our combined sample involved 15 boys and 34 girls, and was diverse in terms of age, household income, and maternal education. DialogPR administration time was less than 2 min, with no problems reported. The DialogPR demonstrated strong internal consistency and reliability (Cronbach's alpha = 0.82), and criterion-related validity with the StimQ-P READ (Spearman's rho coefficient = 0.53). Rasch analysis revealed strong psychometric properties in terms of reliability, variability in item difficulty, and inter-item and item-measure correlations. CONCLUSIONS: Preliminary evidence suggests that the DialogPR may be an efficient means to assess shared reading quality and dialogic reading via caregiver report for clinical and research purposes, warranting further investigation.

Shared Reading Quality and Brain Activation during Story Listening in Preschool-Age Children.

OBJECTIVE: To explore the relationship between maternal shared reading quality (verbal interactivity and engagement) and brain function during story listening in at-risk, preschool-age children, in the context of behavioral evidence and American Academy of Pediatrics, recommendations. STUDY DESIGN: In this cross-sectional study, 22 healthy, 4-year-old girls from low socioeconomic status households completed functional magnetic resonance imaging using an established story listening task, followed by videotaped observation of uncoached mother-daughter reading of the same, age-appropriate picture book. Shared reading quality was independently scored applying dialogic reading and other evidence-based criteria reflecting interactivity and engagement, and applied as a predictor of neural activation during the functional magnetic resonance imaging task, controlling for income and maternal education. RESULTS: Shared reading quality scores were generally low and negatively correlated with maternal distraction by smartphones (P < .05). Scores were positively correlated with activation in left-sided brain areas supporting expressive and complex language, social-emotional integration, and working memory (P <.05, false discovery rate corrected). CONCLUSIONS: Maternal shared reading quality is positively correlated with brain activation supporting complex language, executive function, and social-emotional processing in at-risk, preschool-age children. These findings represent novel neural biomarkers of how this modifiable aspect of home reading environment may influence foundational emergent literacy skills, reinforce behavioral evidence and American Academy of Pediatrics, recommendations, and underscore the potential of dialogic reading interventions to promote healthy brain development, especially in at-risk households.

Effects of dialogic reading for comprehension (LuDiCa) on the social interaction of autistic adolescents and their peers.

BACKGROUND: In today's contemporary world, relationships take a prominent role in the lives of adolescents. However, challenges related to mutual understanding and a lack of inclusive environments can often lead to autistic teens feeling excluded. OBJECTIVE: In order to assess the impact of naturalistic interventions on interpersonal relationships, we conducted an experimental test utilizing Dialogic Reading for Comprehension (LuDiCa) in online reading circles with groups comprising both autistic and neurotypical adolescents. Our focus was on exploring its relevance for enhancing social interaction, particularly in terms of conversational acts, sharing experiences, initiations, and questions. METHODS: Five autistic and five neurotypical students between 11 and 15 years old from a public school in Brasilia, Federal District, participated. We paired groups A and B (made up of trios of teenagers) and groups C and D (made up of pairs) in a multiple baseline design per reading group, in which all groups went through the baseline conditions (BL), intervention (LuDiCa) and maintenance. RESULTS: LuDiCa increased the frequency of conversational acts of both autistic participants and neurotypical peers. In addition, the intervention favored initiations, questions, and sharing experiences, through the shared activity of reading and talking about a work of fiction. Participants rated the intervention in relation to the platform, the book, the reading facilitator, and interaction with peers. We discuss the potential of the facilitator's role in favoring interactions and the potential of LuDiCa as a joint activity for the engagement of adolescents. We also include suggestions for future research focused on the online context and discuss some limitations of the LuDiCa intervention. CONCLUSION: In summary, our study offers initial experimental evidence demonstrating the positive impact of LuDiCa on social interaction behaviors among both autistic and neurotypical adolescents within an inclusive setting.

[A review of dialogic reading intervention in children with developmental language disorder]. / Revisión de la intervención mediante lectura dialógica en niños con trastornos del desarrollo del lenguaje.

INTRODUCTION: Dialogic reading is one of the most used and studied techniques within the frame 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 guidelines. RESULTS: The investigations reviewed show advances in children's lexical, grammatical and pragmatic 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 remarkable issues relate to the books or materials employed and the measures used to assess its effectiveness.

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 sistemática 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, fundamentalmente, 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.

Supporting second language acquisition of bilingual preschool children through professionalization of caregivers in specialized preschool programs.

The aim of the present study was to investigate the effectiveness of a training program on language support strategies and dialogic reading for caregivers working in specialized preschool programs. These programs serve children without a regular childcare place who grow up with one or more languages other than German as the environmental language. Recent studies investigating the development of children attending these programs found only moderate improvements in German receptive language skills, while language support quality of the programs was rated as average. We assessed receptive second language competencies in vocabulary and grammar of n = 48 children and language support competencies of n = 15 caregivers using an interventional pre-posttest design. Receptive vocabulary skills of children supported by trained caregivers (intervention group) were compared to children supported by untrained caregivers (control group, n = 43). We found that both children's and caregivers' competencies increased from pre- to posttest, whereas the control group's receptive vocabulary skills did not increase noticeably. The caregivers' language support competencies influenced the increase of children's receptive grammar but not vocabulary skills. The comparison between the intervention group and control group consistently showed no effect of group membership on children's receptive vocabulary acquisition over time. Since the control group data came from a secondary analysis, only receptive vocabulary skills could be compared. The preliminary results of our study suggest that a caregivers' training on language support strategies and dialogic reading in everyday educational situations support bilingual children's grammar acquisition.

Reduced mother-child brain-to-brain synchrony during joint storytelling interaction interrupted by a media usage.

Parent-child synchrony is related to the quality of parent and child interactions and child development. One very emotionally and cognitively beneficial interaction in early childhood is Dialogic Reading (DR). Screen exposure was previously related to decreased parent-child interaction. Using a hyperscanning Electroencephalogram (EEG) method, the current study examined the neurobiological correlates for mother-child DR vs. mobile phone-interrupted DR in twenty-four white toddlers (24-42 months old, 8 girls) and their mothers. The DR-interrupted condition was related to decreased mother-child neural synchrony between the mother's language-related brain regions (left hemisphere) and the child's comprehension-related regions (right hemisphere) compared to the uninterrupted DR. This is the first neural evidence of the negative effect of parental smartphone use on parent-child interaction quality.

The impact of interactive book sharing on child cognitive and socio-cognitive development (the REaL trial): study protocol for a randomized controlled trial.

BACKGROUND: The quality of children's early home learning environment has an influence on their cognitive development, preliteracy skills, and subsequent educational outcomes. Early intervention programs that promote positive parenting behaviors and child cognition have great potential to positively influence children's school readiness and thereby support social equality. One often advocated parental practice for promoting child language and cognition is interactive book sharing. METHODS: We have conducted a randomized controlled trial to evaluate the effects of a parent-child interactive book sharing intervention on early child language, cognition, and parental behaviors. Participating caregivers and their 10-month-old child were randomized to an interactive book sharing intervention group (n = 59) or to an active control group (n = 56). The intervention was delivered by a facilitator to small groups of parent-child dyads on a weekly basis over 5 weeks. The primary outcomes were child language and socio-cognition; secondary outcomes were child executive function and parental scaffolding, sensitivity and reciprocity during book sharing, and problem-solving tasks. Data were collected at baseline, post-intervention, and at 6 and 12 months post-intervention. DISCUSSION: The Roadmap to Executive function and Language (REaL) trial aims to evaluate the impact of a brief early parenting intervention on key factors for child development, including child cognition and parental behaviors. If this intervention is beneficial for child outcomes, that would be of significance for the development of early interventions to promote child development. TRIAL REGISTRATION: The REaL trial is registered on the International Standard Randomized Controlled Trial Number database, registration number ISRCTN22319305. Retrospectively registered on 7 February 2020.

Dialogic Reading to Empower Executive Functions in Preschoolers.

Among the interventions recently developed to enhance Executive Functions (EFs) in preschoolers, Quincey Quokka's Quest (QQQ) is an illustrated book proposing EF activities embedded within a shared reading framework (Howard et al., 2017). In the present study, the Italian version of QQQ (QQQIT) was tested in 20 typical developing 4-5 year old children. Standardized tests were used to assess EFs pre- and post- intervention. QQQIT was conducted once a week for 8 weeks in small groups. A positive trend was registered in QQQIT performances from the first to the last sessions and a significant improvement, in comparison to the control condition, was obtained in the Color and Form Game test. These results, supporting the feasibility of the QQQIT intervention and its efficacy in increasing shifting abilities, confirm the usefulness of ecological interventions to empower specific EF components in preschool contexts.

Brief Report: A Randomized Controlled Trial of the Effects of RECALL (Reading to Engage Children with Autism in Language and Learning) for Preschoolers with Autism Spectrum Disorder.

This study investigated the effects of a parent-implemented dialogic reading approach-Reading to Engage Children with Autism in Language and Learning (RECALL)-on the engagement in reading and inference-making ability for preschoolers with autism spectrum disorder (ASD). Thirty-one preschoolers (mean age = 5.90 years, SD = 0.69; 26 boys, 5 girls) were randomly assigned to a treatment or control group. Six weeks of RECALL significantly enhanced story comprehension, emotion knowledge, and reading engagement among preschoolers in the treatment group. This might be the first randomized controlled trial testing the effects of RECALL on children with ASD. Our findings suggest that additional instructional support such as the application of a prompting hierarchy during dialogic reading might help children with ASD reap greater benefits from shared book reading.

Enhancing Literacy and Communicative Skills of Students With Disabilities in Special Schools Through Dialogic Literary Gatherings.

Enhancing the quality of learning opportunities for students with disabilities and the learning level attained is a pending challenge. This challenge is especially relevant in the context of special schools, where the learning possibilities derived from interactions with others is limited. However, providing these students with a sufficient level of instrumental learning, such as literacy, and communicative and reasoning abilities is crucial for their subsequent educational and social opportunities. In this case study we analyse a special school that has implemented Dialogic Literary Gatherings with their students as a means to increase learning interactions within the group around the reading and debate of classical books. Semi-structured interviews were conducted with the school principal and with a teacher of the transition to adult life course, and two focus groups were conducted with teachers-one with primary education teachers and one with secondary education teachers-and two focus groups with students-one with primary education students and one secondary education and transition to adult life students-. On the one hand, results show the characteristics of the Dialogic Literary Gatherings that allowed these students to participate and learn. On the other hand, several improvements have been observed. First, regarding instrumental learning, students increased their motivation for reading, and improved their communicative and reasoning abilities and in their reading proficiency. Second, regarding students' behavior, conflict has reduced, solidarity attitudes have increased, and they have acquired dialogic and argumentative habits. Finally, at the emotional level, they gained self-esteem and confidence and feel more empowered to make their voice heard.

Reading Picture Books With Elements of Positive Psychology for Enhancing the Learning of English as a Second Language in Young Children.

This study aimed to investigate the learning effectiveness of reading picture books with EMPATHICS elements using dialogic reading techniques in enhancing young children's English language learning and creativity. EMPATHICS is an acronym of Emotion and Empathy, Meaning and Motivation, Perseverance, Agency and Autonomy, Time, Habits of Mind, Intelligences, Character Strengths, and Self Factors (Oxford, 2016). It adopted a quasi-experimental design, and 78 kindergarten children aged from 4 to 5 years old in a cluster group were randomly assigned to the experimental and control groups. Both groups read the same four picture books with their homeroom teachers, including two readers suggested in the curriculum and two picture books with enriched elements for 12 sessions over 8 weeks. A doubly multivariate analysis was used to measure the main time and group effects and the interaction effect on the performance of English receptive vocabulary, syntactic complexity, and verbal creativity of the two groups across three different times. There were significant differences only in the interactive effect on syntactic complexity. Children in the experimental condition gave responses with more complex syntactic structures. Significant time effects for receptive vocabulary, syntactic complexity, and verbal creativity were observed in all children. Reading enriched English texts better prepares children to creatively and effectively express themselves. This study extends previous research in two ways. First, this study is one of the few studies on the effectiveness of dialogic reading using EMPATHICS-enriched picture books among young language learners. Second, this study investigates the effects of dialogic teaching on English as a second language development in young children. The educational implications will be discussed.

The impact of early-years provision in Children's Centres (EPICC) on child cognitive and socio-emotional development: study protocol for a randomised controlled trial.

BACKGROUND: There are marked disparities between pre-school children in key skills affecting school readiness, disparities that commonly persist and influence children's later academic achievements, employment, and adjustment. Much of this disparity is linked to socio-economic disadvantage and its impact on the home learning environment. Children's Centres are an ideal context in which to implement and evaluate programmes to address this problem. They principally serve the 30% worst areas on the Indices of Deprivation Affecting Children, providing for families from the antenatal period up to age 5 years, aiming to promote parenting skills and provide care for children. METHODS: We are conducting a randomised controlled trial, based in Children Centres, to evaluate a parenting intervention for caregivers of children between 28 and 45 months of age. The intervention provides training to parents in dialogic book-sharing. The training is run by a facilitator who sees parents in small groups, on a weekly basis over 7 weeks. The study is a cluster randomised controlled trial. Twelve of the Children's Centres in the town of Reading in the UK have been randomly assigned to an index or control condition. The primary outcome is child cognition (language, attention, and executive function); and secondary outcomes are child social development, behaviour problems, and emotion regulation, parenting during book-sharing and problem solving and parental child behaviour management strategies. Data are collected at baseline, post-intervention and 4-6 months post-intervention. DISCUSSION: The Impact of Early-years Provision in Children's Centres trial (EPICC) aims to evaluate the impact of an early parenting intervention on several key risk factors for compromised child development, including aspects of parenting and child cognition, social development, behaviour problems and emotion regulation. The study is being carried out in Children's Centres, which largely serve the most disadvantaged families in the UK. Since the intervention is brief and, with modest levels of training, readily deliverable within Children's Centres and similar early childcare provision centres, demonstration that it is of benefit to child cognition, socio-emotional development and behaviour would be important. TRIAL REGISTRATION: ISRCTN Registry, ISRCTN28513611 . Registered on 28 March 2017. This is version 1 of the protocol for the EPICC trial.

Shared Book Reading Promotes Not Only Language Development, But Also Grapheme Awareness in German Kindergarten Children.

Effects of shared book reading on expressive vocabulary and grapheme awareness without letter instruction in German kindergarteners (longitudinal; N = 69, 3;0-4;8 years) were investigated. Expressive vocabulary was measured by using a standardized test; grapheme awareness was measured by asking children to identify one grapheme per trial presented amongst non-letter distractors. Two methods of shared book reading were investigated, literacy enrichment (additional books) and teacher training in shared book reading strategies, both without explicit letter instruction. Whereas positive effects of shared book reading on expressive vocabulary were evident in numerous previous studies, the impact of shared book reading on grapheme awareness has not yet been investigated. Both methods resulted in positive effects on children's expressive vocabulary and grapheme awareness over a period of 6 months. Thus, early shared book reading may not only be considered to be a tool for promoting the development of expressive vocabulary, but also for implicit acquisition of grapheme awareness. The latter is considered an important precondition required for the explicit learning of grapheme-phoneme conversion rules (letter knowledge).

Desarrollo del discurso narrativo en niños ecuatorianos de 6 años / The development of narrative discourse in Ecuadorian 6-year-old children

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.
