Contextos da prática docente: (re)pensando o papel do contexto em intervenções com professores da educação infantil e novas abordagens para a leitura compartilhada

Although the randomized controlled trial has been regarded as the sine qua non in recent years, we argue that understanding contexts for teacher practice is a critical factor in the implementation of intervention, but has often been overlooked in educational research design. In this paper, we argue that randomized trials may not be ideal for educational contexts that are multi-faceted, complex and often part of other community-based initiatives. To make this argument, we describe a study from “the context out,” a different lens than is typical in education research. In doing so, we consider how varied contexts create both constraints and affordances for teachers to engage in an intervention. Examining how teachers engage with new curricular practices, we focus closely on five early childhood centers in high poverty neighborhoods, using mixed methods to understand both the influence of the intervention as well as the conditions that either supported or thwarted changes in practice. Our findings suggest that context plays a major role in educational practice, which has important implications for approaches to research in the future. Given this reality, we argue that an understanding of the context in which an intervention takes place must be considered in any calculation of “what works” in classrooms.Aunque los experimentos controlados aleatorios han sido considerados como condición sine qua non en los últimos años, argumentamos que la comprensión de los contextos de la práctica docente es un factor crítico en la implementación de intervenciones, pero a menudo se han pasado por alto en los diseños de investigación educativa. En este trabajo, argumentamos que los experimentos controlados aleatorios pueden no ser ideales para los contextos educativos que son de facetas múltiples, complejas y con frecuencia parte de otras iniciativas basadas en la comunidad. Para sustentar este argumento, describimos un estudio "fuera de contexto," un objetivo no típico en la investigación en educación. Tenemos en cuenta como contextos variados crean tanto restricciones como posibilidades para que docentes participen en una intervención. Examinamos cómo los docentes se comprometen con nuevas prácticas curriculares, focalizando particularmente en cinco centros para la primera infancia en barrios con altos niveles de pobreza, usando métodos mixtos para entender tanto la influencia de la intervención, así como las condiciones para favorecer o dificultar cambios en las prácticas. Nuestros hallazgos sugieren que el contexto juega un papel importante en la práctica educativa, lo que tiene importantes implicaciones para pensar investigaciones futuras. Dados nuestros resultados argumentamos que la comprensión del contexto en el que se lleva a cabo una intervención debe ser considerada en el cálculo de "lo que funciona" en las aulas.Apesar de experimentos controlados randomizados foram considerados como condição sine qua non, nos últimos anos, argumentamos que a compreensão dos contextos de prática de ensino é um fator crítico para a implementação de intervenções, mas têm sido muitas vezes negligenciado em projetos de investigação educacional.

Two Beginning Kindergarten Teachers Planning for Integrated Literacy Instruction

This study reports the characteristics and strategies of 2 beginning kindergarten teachers\u27 planning for an integrated approach to literacy instruction. Using ethnographic observational and analytic techniques, we describe features and structures of integrated instruction as a planning \u27\u27problem.\u27\u27 The teachers\u27 problem-solving strategies under the conditions of this task are also examined. Results revealed the multiple and complex nature of integrated instruction as a planning problem. Based on domain and componential analyses, the task appeared to include at least 6 kinds of planning activity and to make multiple demands on the planners\u27 time, specificity of planning, level of pedagogical knowledge, and degree of work. Further analysis indicated a recurring pattern in the teachers\u27 organization of their activities, suggesting a 4-phase planning model. An examination of the teachers\u27 verbal accounts for indicators of mental processes used in their problem solving indicated strategies of the forward-search and problem-reduction type, with the former predominating. Features and structures of integrated instructional planning as a problem type are summarized from the teachers\u27 perspective as novices. We also discuss possible implications for teacher preparation and development and areas for further research

Screens, apps, and digital books for Young children: the promise of multimedia

Just beginning to understand the potentials new technologies might bring to the learning environments of young children, we invited authors to submit articles that investigate multimedia sources and their effect on learning settings. Two main themes emerged—how digitization changes the learning environment and adult-child interaction in particular and which digital affordances enrich digital materials and how these changes affect learning. We finish with “alerts” to further explore more the hidden potentials of new technologies and how routines such as book reading might change and become more effective in some respects.publishedVersio

Educational Effects of a Vocabulary Intervention on Preschoolers' Word Knowledge and Conceptual Development: A Cluster‐Randomized Trial

The purpose of this study was to examine the hypothesis that helping preschoolers learn words through categorization may enhance their ability to retain words and their conceptual properties, acting as a bootstrap for self‐learning. We examined this hypothesis by investigating the effects of the World of Words instructional program, a supplemental intervention for children in preschool designed to teach word knowledge and conceptual development through taxonomic categorization and embedded multimedia. Participants in the study included 3‐ and 4‐year‐old children from 28 Head Start classrooms in 12 schools, randomly assigned to treatment and control groups. Children were assessed on word knowledge, expressive language, conceptual knowledge, and categories and properties of concepts in a yearlong intervention. Results indicated that children receiving the WOW treatment consistently outperformed their control counterparts; further, treatment children were able to use categories to identify the meaning of novel words. Gains in word and categorical knowledge were sustained six months later for those children who remained in Head Start. These results suggest that a program targeted to learning words within taxonomic categories may act as a bootstrap for self‐learning and inference generation. كان الغرض من هذه الدراسة هو فحص فرضية أن مساعدة الأطفال في الروضة تعلم كلمات عن طريق التصنيف بإمكانه أن يعزز من قدراتهم على تذكر الكلمات وخصائصها المفاهيمية، بوصفها محفزا للتعلم. قمنا بفحص هذه الفرضية وذلك بالتحقيق في أثر البرنامج التعليمي "عالم المفردات" (WOW) الذي يعتبر تدخلا تكميليا لأطفال الروضة ومصمما من أجل تعليم معرفة الكلمات والتطور المفاهيمي، من خلال النظام التصنيفي ووسائل الإعلام. تضمنت الدراسة مشاركين تتراوح أعمارهم بين 3 و4 سنوات ينتمون إلى 28 روضة أطفال، التي تنتمي إلى 12 مدرسة, خضعت عشوائيا للبحث ومراقبة المجموعات. جرى تقييم الأطفال على معرفة الكلمات واللغة التعبيرية والمعرفة المفاهيمية وأصناف وخصائص المفاهيم في تدخل لمدة سنة كاملة. أظهرت النتائج أن الأطفال الذين خضعوا للبرنامج التعليمي "عالم المفردات" (WOW) قد تفوقوا بصورة مستمرة على نظرائهم الذين خضعوا للمراقبة. علاوة على ذلك, فإن أطفال البحث قد تمكنوا من استخدام الأصناف والتعرف على معنى الكلمات الجديدة. استمر اكتساب الكلمات والمعرفة التصنيفية بعد 6 أشهر بالنسبة للأطفال الذين بقوا في روضة الأطفال. توحي هذه النتائج إلى أنه يمكن لبرنامج يهدف إلى تعلم الكلمات أن يعمل كمحفز للتعلم الذاتي، وتوليد الاستنتاجات. 本研究旨在考查一个假设：帮助学龄前儿童通过分类来学习单词，可提高他们记忆单词及其概念属性的能力，从而发展他们的自主学习能力。作者通过调查「单词世界」(WOW)教学计划的影响来考查这个假设。该教学计划是一个学龄前儿童补充干预计划，旨在透过使用分类学的分类方法及嵌入式多媒体，教授单词知识和发展单词概念。研究参与者是来自12所学校中的28个「启蒙计划」学前儿童班里的3‐4岁儿童，他们被随机分配到干预组和对照组。在一年的干预中，儿童接受单词知识、表达语言、概念知识、类别和概念属性的评估。结果显示，「单词世界」(WOW)干预组的表现一致地优于对照组；此外，干预组儿童可以使用类别来确定新词的词义。仍然留在「启蒙计划」班里的儿童，其单词和类别知识的改进保持稳定至干预后6个月。这些研究结果显示，针对透过分类学的分类方法来学习单词的教学计划，可引导儿童凭自己的力量学习自学和产生推断。 Cette étude avait pour but d'examiner l'hypothíse qu'aider des enfants d'âge préscolaire à apprendre des mots en les catégorisant pourrait favoriser leur capacité à retenir les mots et leurs propriétés, agissant alors comme une amorce d'auto‐apprentissage. Nous avons examiné cette hypothíse en analysant les effets du matériel d'enseignement le Monde des Mots (MDM), un supplément pédagogique destiné aux enfants d'âge préscolaire conçu pour la connaissance des mots et le développement des concepts à l'aide d'une catégorisation taxinomique avec multimédia impliqué. Ont participé à l'étude des enfants de 3 et 4 ans provenant de 28 classes Head Start issus de 12 écoles assignées au hasard au groupe de traitement et au groupe contrôle. Les enfants ont été évalués sur leur connaissance des mots, l'expression orale, les connaissances conceptuelles, les catégories et les propriétés des concepts tout au long de l'année de l'intervention. Les résultats ont montré que les enfants du groupe de traitement MDM ont de maniíre systématique dépassé leur contrepartie du groupe contrôle; en outre, les enfants soumis au traitement ont été en mesure de se servir des catégories pour trouver le sens des mots nouveaux. Les bénéfices dans la connaissance des mots et les connaissances catégorielles sont demeurés six mois plus tard chez les enfants restés dans Head Start. Ces résultats suggírent qu'un programme visant l'apprentissage de mots au sein de catégories taxonomiques peut agir comme une amorce pour l'auto‐apprentissage et la production d'inférences. Проверялась гипотеза о том, что категоризация лексики при обучении дошкольников новым словам может существенно увеличить способность к запоминанию слов и их концептуальных свойств и стимулировать малышей к самообучению. Для расширения их словарного запаса и умения работать с концептами авторы исследовали учебный модуль “Мир слов” (WOW), разработанный в качестве дополнительного вмешательства для дошкольников, которые обучаются по программе Head Start. WOW знакомит детей с таксономической классификацией посредством мультимедийных средств. Трех‐ и четырехлетние дети из 28‐и дошкольных групп в 12‐и школах были случайным образом включены либо в экспериментальную, либо в контрольную группу. На протяжении годичного обучения оценивалось знание слов, выразительность речи, знание концептов, их свойств и категорий, к которым они могут быть причислены. Дети, обучавшиеся по программе WOW, стабильно показывали более высокие результаты, чем их ровесники из контрольных групп. Помимо прочего, эти дети способны использовать категоризацию для определения значений новых слов. Через полгода после окончания обучения эти дети продолжали опережать сверстников по знанию слов и умению категоризировать. Это свидетельствует о том, что программа, предлагающая изучение слов в рамках таксономических категорий, может помочь вырастить поколение, которое будет способно к самообучению и к самостоятельным выводам. La meta de este estudio fue el de investigar la hipótesis que ayudar a los preescolares a aprender palabras por medio de la categorización mejoraría su capacidad de retener palabras y sus propiedades conceptuales, sirviendo de arranque para el auto aprendizaje. Investigamos esta hipótesis estudiando los efectos del programa de enseñanza World of Words (Mundo de palabras; WOW por sus siglas en inglés), una intervención adicional para niños preescolares diseñada para el aprendizaje de palabras y el desarrollo conceptual por medio de la categorización taxonómica y el uso de diversos medios. En este estudio participaron niños de 3 y 4 años de 20 aulas de Head Start en 12 escuelas escogidas al azar en cuanto a grupos de tratamiento y de control. En un año completo de intervención, se evaluaron los estudiantes en cuanto a su conocimiento de palabras, su lenguaje expresivo, su conocimiento conceptual, y las categorías y propiedades de los conceptos. Los resultados mostraron que los niños del grupo de WOW sistemáticamente superaban a los niños del grupo de control; además, los niños del grupo de tratamiento podían usar categorías para encontrar el significado de palabras nuevas. Los adelantos en el conocimiento de palabras y categorías todavía existían 6 meses más tarde para los niños que seguían con Head Start. Estos resultados sugieren que un programa dedicado al aprendizaje de palabras dentro de categorías taxonómicas puede ayudar al autoaprendizaje y la producción de inferencias.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/88072/1/RRQ.46.3.3.pd

Acquisition from Storybooks

For young children, storybooks may serve as especially valuable sources of new knowledge. While most research focuses on how extratextual comments influence knowledge acquisition, we propose that children's learning may also be supported by the specific features of storybooks. More specifically, we propose that texts that invoke children's knowledge of familiar taxonomic categories may support learning by providing a conceptual framework through which prior knowledge and new knowledge can be readily integrated. In this study, 60 5-year olds were read a storybook that either invoked their knowledge of a familiar taxonomic category (taxonomic storybook) or focused on a common thematic grouping (traditional storybook). Following the book-reading, children's vocabulary acquisition, literal comprehension, and inferential comprehension were assessed. Children who were read the taxonomic storybook demonstrated greater acquisition of target vocabulary and comprehension of factual content than children who were read the traditional storybook. Inferential comprehension, however, did not differ across the two conditions. We argue for the importance of careful consideration of book features and storybook selection in order to provide children with every opportunity to gain the knowledge foundational for successful literacy development

Dyadic Speech-based Affect Recognition using DAMI-P2C Parent-child Multimodal Interaction Dataset

Automatic speech-based affect recognition of individuals in dyadic conversation is a challenging task, in part because of its heavy reliance on manual pre-processing. Traditional approaches frequently require hand-crafted speech features and segmentation of speaker turns. In this work, we design end-to-end deep learning methods to recognize each person's affective expression in an audio stream with two speakers, automatically discovering features and time regions relevant to the target speaker's affect. We integrate a local attention mechanism into the end-to-end architecture and compare the performance of three attention implementations -- one mean pooling and two weighted pooling methods. Our results show that the proposed weighted-pooling attention solutions are able to learn to focus on the regions containing target speaker's affective information and successfully extract the individual's valence and arousal intensity. Here we introduce and use a "dyadic affect in multimodal interaction - parent to child" (DAMI-P2C) dataset collected in a study of 34 families, where a parent and a child (3-7 years old) engage in reading storybooks together. In contrast to existing public datasets for affect recognition, each instance for both speakers in the DAMI-P2C dataset is annotated for the perceived affect by three labelers. To encourage more research on the challenging task of multi-speaker affect sensing, we make the annotated DAMI-P2C dataset publicly available, including acoustic features of the dyads' raw audios, affect annotations, and a diverse set of developmental, social, and demographic profiles of each dyad.Comment: Accepted by the 2020 International Conference on Multimodal Interaction (ICMI'20
