A formative study of rhythm and pattern: semiotic potential of multimodal experiences for early years readers

Peters, J. Beryl 08 September 2011 (has links)
Literacy education defined as the reading and writing of print text is undergoing a paradigmatic shift towards a pedagogy of multiliteracies (Cole & Pullen, 2010). At the same time, demands for rapid, efficient, and accurate reading skills escalate (Katzir et al., 2006) in a global society with increasingly instant and complex literacy requirements. Musical rhythm plays a role in multiliteracy and print literacy learning. Rhythm is essential for music making and reading, and may facilitate print literacy for all children, including those who struggle with traditional print-based teaching and learning. The purpose of this research was to investigate the potential for the semiotic resource of rhythm to engage early years children in print and non-print literacy learning. A twelve week mixed methods quasi-experimental study was conducted to examine the effects of a multimodal Orff-based learning design on elements of reading and rhythm for grades one to three children in four schools. Students (N = 169) from nine classrooms were non-randomly assigned to one of two groups. The researcher instructed both groups two to three times a week totaling twenty-five sessions in each homeroom classroom. The experimental groups participated in Orff-based learning experiences that focused on elements of rhythm and prosodic oral reading fluency. The control group listened to and sang song-storybooks. Beat performance and oral reading rate assessments were administered as pre- and post-tests to each group. Struggling readers in the experimental group significantly improved on measures of oral reading rate compared to struggling readers in the control group using matched pairs t-procedures and analyses of variance. Associations between beat performance and oral reading rate were explored using bivariate and multivariate regression and correlation analysis. A strong positive correlation was found between measures of beat competency and measures of oral reading rate. Qualitative methods using grounded theory, semiotic data analysis, multimodal analysis, action research, and design research methods placed within a bricolage framework (Kincheloe & Berry, 2004) and examined through the lens of complexity thinking (Davis & Sumara, 2006) added multiperspectival meaning-making of data. Findings pointed to the value of multimodal music and rhythm experiences for engaged, deep, meaningful print and non-print learning for diverse individual and classroom collective learners in both control and experimental classrooms. Beat competency was important to both print and music literacy learning in experimental classrooms. Beat experiences were compelling, equitable, and appeared to organize music, oral language, and print literacy into meaningful and accessible patterns and structures. Similar findings may be occasioned through an ontology of multimodal richness, a complex epistemology, embodied ways of knowing and communicating, and systemic shared beliefs and values.

Möjligheter och hinder att arbeta språkutvecklande i förskoloaklass : Med fokus på fonologisk medvetenhet

Pettersson, Christina January 2018 (has links)
Thepurpose of my study is to investigate pedagogues experience of working methodsto promote linguistic phonological development in pre-school children whoselanguage development is weak. The aim is further tohighlight the obstacles and opportunities that the pedagogues in the studyconsider to aggravate and stimulate the work of language development inchildren with weak phonological awareness and how the organization's designaffects the teachers 'work in this area. Today's society places highdemands on reading and writing skills for citizens who, in turn, place highdemands and good knowledge of reading and writing lessons for all educators andteachers. Through qualitative semistructured interviews, I interviewed fiveeducator active pre-school class. The five teaching educators are from fivedifferent schools in four municipalities. The results of the study have shownthat all educators work conscious language development with language games,more or less systematically and organized. The Bornholm model is the screeningmaterial and exercises used most frequently. The biggest obstacles theeducators need to deal with is the absence of colleagues. Then the planningtime that everyone considers necessary to provide quality education is lost.Factors that promote linguistic work on phonological awareness are commoncompetence development and collaboration in the work team. In my limited study,I have gained insight into how language development works in the municipalities.I have also received good examples of language development, fun working method andmethods.

The development of a formal diagnostic assessment tool for spelling in the foundation phase

Richards, Sonja 12 1900 (has links)
This research is concerned with an investigation into the development of a formal diagnostic assessment tool for spelling in the foundation phase. A literature study and information acquired from educators provided information to compile a suitable spelling list that could be used as a diagnostic tool in the foundation phase. A self-designed questionnaire was administered to fifty educators Who provided their expert opinion regard the spelling list. This was followed up by second questionnaire that was based on the analysis and interpretation of the first. The Delphi-technique was applied to this investigation. The study was complete when consensus was reached among the educators with regard to which words should be included in the final spelling list. / Psychology of Education / M. Ed.

Ensino da leitura : como as letras são introduzidas no livro didático porta aberta - 1º ano

Araújo, Cristiane Menezes de 20 July 2017 (has links)
The present dissertation brings reflections on the initial teaching and learning of reading for literacy and citizenship, taking as object of investigation the textbook: Porta Aberta: letramento e alfabetização – 1º. Ano, da Ed. FTD, de Carpaneda & Bragança (2011), commonly adopted in public schools in Aracaju / SE. It aims to analyze the way how this book introduces the vowel and consonantal letters, in the light of the theoretical-methodological assumptions of the Scliar System of Literacy, considering (or not) the order of increasing complexity in the introduction of graphemes for the initial learning of the reading, such as the simplicity of the traces that make up the letters and their articulation; listening for the realization of the most perceptible phonemes by the learner, represented by the respective grapheme; the biunivocity relationship of each one of them; the graphemes that represent phonemes without variants determined by the phonetic context, among other complexities, as well as if the letters are (or aren't) presented by their names or the value that they represent. The theoretical-methodological foundations are firmly established in the works of Scliar-Cabral (2016; 2014; 2013b; 2007; 2003), whose purposes serve teaching practices aligned with the advanced discoveries of neuroscience, psycholinguistics, linguistics and the science concern to education, with emphasis on teaching strategies that highlight the importance of recognizing the graphic traits that identify the letters and the phonemic and phonological awareness in this initial phase of literacy. We know that, although the teaching of reading is compulsory in schools, the central focus for the development of this educational process is always more focused on the mechanical writing of letters, which imply the detriment of the effective learning process: there it is the causes of low reading and writing performance, according to the results presented in various National Assessments (ANA, 2015). We understand that unfortunately, even facing such a low reading performance of our children, the school still ends up silencing these questions, by not proposing an initial reading learning with more criticism, reflection and investment in the continued education of literacy teachers. It opts, then, for the reproduction of outdated approaches that, admittedly, present terrible results in national and international evaluations, starting with textbooks, sometimes they are not recommended by psycholinguistics scholars and related sciences that turn to the promising teaching of that specific ability, as evidenced in this study. The results of the work show that the methodology adopted in the textbook Porta Aberta: letramento e alfabetização – 1º. ano contrary to the advances already achieved for a scientifically based literacy by presenting the letters through nomination and according to the order of the alphabet and not according to the complexity of articulation of the traits that make them up, elencada in this study, and by introducing the vowel letters without interacting with the consonants. Finally, we believe that a process of the initial learning of reading for the exercise of citizenship passes through the automation of the recognition of: 1º - what are, how many are and how the traces that form the letters are combined; 2º what are the graphemes of written Brazilian Portuguese and the respective values (phonemes) that they represent (phonemic awareness); 3º - where the graphic accent of greater intensity goes in the stressed words and identification of the most frequent unstressed words, like articles and the coordinating conjunction "and", which allows the fast and fluent reading, to achive the textual understanding. / A presente dissertação traz reflexões sobre o ensino e a aprendizagem iniciais de leitura para o letramento e cidadania, tomando como objeto de investigação o livro didático Porta Aberta: letramento e alfabetização – 1º. Ano, da Ed. FTD, de Carpaneda & Bragança (2011), comumente adotado em escolas públicas de Aracaju/SE. Objetiva analisar o modo como o referido livro introduz as letras1 vocálicas e consonantais, à luz dos pressupostos teórico-metodológicos do Sistema Scliar de Alfabetização, atentando (ou não) à ordem de complexidade crescente na introdução de grafemas para a aprendizagem inicial da leitura, tais como a simplicidade dos traços que compõem as letras e sua articulação; a escuta da realização dos fonemas mais perceptíveis pelo aprendiz, representados pelo respectivo grafema; a relação de biunivocidade de cada um deles; os grafemas que representam fonemas sem variantes determinadas pelo contexto fonético, dentre outras complexidades, bem como se as letras são (ou não) apresentadas pelo seu nome ou pelo valor que elas representam. Os fundamentos teórico-metodológicos firmam-se nos trabalhos de Scliar-Cabral (2016; 2014; 2013b; 2007; 2003), cujos propósitos atendem a práticas de ensino alinhadas às descobertas avançadas da neurociência, da psicolinguística, da linguística e das ciências voltadas à educação, com ênfase nas estratégias de ensino que relevam a importância do reconhecimento dos traços gráficos que identificam as letras e da consciência fonêmica e fonológica nesta fase inicial da alfabetização. Sabemos que, embora o ensino da leitura seja obrigatório nas escolas, o foco central para o desenvolvimento desse processo educacional costuma estar sempre mais voltado para a escrita mecânica das letras, em detrimento do processo efetivo de aprendizagem: estão aí as causas dos baixos índices de rendimento em leitura e escrita, conforme os resultados apresentados nas diversas Avaliações Nacionais (ANA, 2015). Entendemos que, infelizmente, mesmo diante de desempenho em leitura tão baixo de nossas crianças, a escola ainda acabe silenciando essas questões, ao não propor uma aprendizagem inicial da leitura com mais criticidade, reflexão e investimento na formação continuada de alfabetizadores. Opta, então, pela reprodução de abordagens ultrapassadas que, reconhecidamente, apresentam péssimos resultados nas avaliações nacionais e internacionais, a começar, pelos livros didáticos, por vezes, não recomendados por estudiosos da psicolinguística e das ciências afins que se voltam para o ensino promissor da referida habilidade, como evidenciamos no presente estudo. Os resultados do trabalho evidenciam que a metodologia adotada no livro didático Porta Aberta: letramento e alfabetização – 1º. ano contraria os avanços já alcançados para uma alfabetização cientificamente fundamentada, por apresentar as letras mediante a nomeação e conforme a ordem do alfabeto e não conforme a complexidade de articulação dos traços que as compõem, elencada no presente estudo, e por introduzir as letras vocálicas sem interação com as consoantes. Por fim, acreditamos que um processo da aprendizagem inicial da leitura para o exercício da cidadania passa pela automatização do reconhecimento de: 1º - quais são, quantos são e como se combinam os traços que formam as letras; 2º quais são os grafemas do português brasileiro escrito e os respectivos valores (fonemas) que eles representam (consciência fonêmica); 3º - onde cai o acento de intensidade maior nos vocábulos tônicos e identificação dos vocábulos átonos mais frequentes, como artigos e a conjunção coordenativa “e”, o que permite a leitura rápida e fluente, para se chegar à compreensão textual. / São Cristóvão, SE

Segin, Miriam 25 August 2010 (has links)
Made available in DSpace on 2016-03-15T19:39:35Z (GMT). No. of bitstreams: 1 Miriam Segin.pdf: 2813413 bytes, checksum: f192e7858349d5ff3ad275af7e9ccf69 (MD5) Previous issue date: 2010-08-25 / Williams-Beuren Syndrome (WBS) is a genetic affection determined by the microdelation of contiguous genes in 7q11.23. The genetic profile of WBS is characterized by the visualconstructive deficit that contrasts with the good performance in verbal tasks, which sustains the hypothesis of dissociation between these abilities. This grants the syndrome peculiar cognitive and behavioral frames. The objective of this research is to describe the pattern of competences in tasks of linguistic abilities in 22 children and adolescents with WBS, aged between 7and 18 (M=11,6; DP=3,7), students of the 1st to 6th grades of elementary and special schools. We used the following instruments: WISC-III (to evaluate intellectual abilities); Wisconsin (used in neuropsychological assessment of abstract reasoning and cognitive strategies); CBCL/6-18 (behavioral assessment); Token-Comp (TT) used to working memory assessment; Peabody Picture Vocabulary Test (PPVT) used to receptive language assessment; Phonological Awareness by Oral Production Test; Syntactic Awareness Test; Word-Reading Efficiency Test; Test of Naming Images by Choosing Words; Test of Naming Images by Writing. The results of WISC-III, Wisconsin and CBCL/6-18 demonstrate mild to moderate intellectual disability, difficulty in concentration and identification of patterns of change, emotional and relationship problems, lack of attention, behavior disorders, challenge and opposition and somatic complaints. The results of TT and PPVT show that the receptive vocabulary is below expected for the level of schooling and age, and is close to the data found in 4-year-old-children. In the abilities of phonological and syntactic awareness, results indicate great deficiencies, with performances equivalent to those of 3-year-old children at the Phonological Awareness by Oral Production Test and of 4-year-olds at the Syntactic Awareness Test. No progression was found according to the increase of school grade. The tests Word-Reading Efficiency, Naming Images by Choosing Words and Naming Images by Writing were taken by 4 participants that presented deficits in the reading ability with graphophonemic decoding. They make more orthographic and semantic mistakes and show low capacity of naming by writing. Thus, it was possible to verify that the sample presents deficits in receptive language and work memory, difficulties in phonological and syntactic processing tasks, which are important factors to the proper development of the capacity to read and write / A Síndrome de Williams-Beuren (SWB) é uma afecção genética determinada pela microdeleção de genes contíguos em 7q11.23. O perfil cognitivo da SWB é conhecido pelo prejuízo viso-construtivo que contrasta com melhor desempenho em tarefas verbais, o que sustenta a hipótese de dissociação entre essas habilidades, conferindo a esta síndrome um quadro cognitivo e comportamental peculiar. O objetivo deste estudo é descrever o padrão das competências em provas de habilidades lingüísticas de 22 crianças e adolescentes com SWB, com idades entre 7 e 18 anos (M= 11,6; DP=3,7), estudantes do 1º ao 6º ano do ensino fundamental e de Escolas Especiais. Foram utilizados os instrumentos: WISC-III (avaliação do potencial intelectual); Wisconsin (avaliação neuropsicológica de habilidades de raciocínio abstrato e estratégias cognitivas); CBCL/6 18 (perfil comportamental); Token-Comp (TT) (memória de trabalho); Teste de Vocabulário por Imagens Peabody (TVIP) (linguagem receptiva); Prova de Consciência Fonológica por produção Oral (PCFO); Prova de Consciência Sintática (PCS); Teste de Competência de Leitura de Palavras (TCLP); Teste de nomeação de figuras por escolha de palavras (TNF1 escolha) e o Teste de nomeação de figuras por escrita (TNF2 escrita). Os resultados nos testes WISC-III, Wisconsin e CBCL/6 18 apresentaram deficiência intelectual de leve à moderada, maior dificuldade em concentração e identificação de padrões de mudança, problemas afetivos e de relacionamento, desatenção, transtornos de conduta, desafio e oposição e queixas somáticas. Nos testes TT e TVIP foi possível observar que o vocabulário receptivo está abaixo do esperado para a escolaridade e para a idade, próximo ao encontrado em crianças de 4 anos. Nas habilidades de consciência fonológica e consciência sintática, os resultados mostraram grande comprometimento, com desempenho equivalente ao de crianças de 3 anos de idade na PCFO e de 4 anos na PCS, sendo que não foi identificada progressão em relação á série. Os testes TCLP, TNF1 e TNF2 foram realizados por 4 sujeitos que apresentam déficits de habilidade de leitura com decodificação grafofonemica, cometem mais erros semânticos e ortográficos e revelam baixa capacidade de nomeação por escrita. Desta maneira, foi possível identificar que, nessa amostra, há comprometimento de linguagem receptiva e de memória de trabalho, dificuldades em tarefas de processamento fonológico e sintático, os quais são fatores importantes para o bom desenvolvimento da leitura e da escrita

Participaram dessa pesquisa um total de 74 crianças matriculadas, inicialmente, no 4o ano do Ensino Fundamental (EF), as quais foram avaliadas uma segunda vez após os dois meses iniciais do 5º ano do EF, sendo 53 crianças de escolas municipais e 21 crianças de uma escola estadual. Avaliou-se a consciência morfológica, consciência fonológica, memória de trabalho fonológica, nomeação seriada rápida, inteligência, engajamento escolar e a leitura (precisão, fluência e compreensão) nos alunos participantes. Os resultados evidenciaram que as habilidades de precisão e compreensão de leitura contribuem de forma positiva para a consciência fonológica. Também se identificou uma contribuição da memória de trabalho fonológica para a fluência de leitura. Além disso, a nomeação seriada rápida contribui positivamente para a compreensão de leitura e em relação ao engajamento escolar, identificou-se uma contribuição positiva do engajamento comportamental para a habilidade de compreensão de leitura. / The present study investigated the relation between cognitive predictors of reading and school engagement with reading skills. Seventy-four children from Brazilian public schools took part on this study. They were initially evaluated when coursing 4th grade and were evaluated a second time while coursing the second month of 5th grade. They were evaluated on morphological awareness, phonological awareness, phonological working memory, rapid automatized naming, student engagement and reading skills (precision, fluency, and comprehension). Results showed that both accuracy and reading comprehension positively contribute to phonological awareness. In addition, it was possible to identify a contribution of the phonological working memory to the reading fluency. Besides that, the study revealed that rapid automatized naming positively contributes to reading comprehension. In regards to student engagement, the study identified a positive contribution of behavioral engagement to reading comprehension.

Fonologisk medvetenhet : En studie av fyra lärares uppfattning om och arbete med fonologisk medvetenhet / Phonological awareness : A study of four active teachers’ perception of and work with phonological awareness.

Immonen, Isabella January 2016 (has links)
This study investigates how four teachers working in preschool class–grade 3 perceive the concept of phonological awareness, how they work to stimulate this awareness and whether they see any change over time. Four teachers were interviewed and turned out to have different perceptions of what phonological awareness is. The interviewed teachers obtained their teaching certificates in different years, which can explain the differences in their knowledge and use of the concept. Half of them worked according to the Bornholm model, which is based on phonological awareness. Those who said that they worked more according to the Whole Language and LTG method nevertheless sometimes used rhymes and chants and language exercises, mostly because they appreciated the playfulness and pleasure of these exercises. Through in-service training and contact with other teachers, the interviewed teachers have become increasingly interested in the concept of phonological awareness.

L’impact de la variabilité articulatoire sur la perception auditive et l’acquisition de la production verbale chez des enfants présentant une dyslexie phonologique de CE1 / The impact of articulatory variability on auditory perception and the acquisition of verbal production in children with phonological dyslexia EC1

Derbal, Amel 23 January 2015 (has links)
Selon la littérature, la dyslexie est une difficulté d’apprentissage de la lecture, non liée à un retard mental, à un déficit sensoriel et ni à l’environnement social ou familial défavorisé. L’enfant dyslexique présente un écart de 18 mois à 24 mois par rapport aux réalisations scolaires d'un sujet en lecture, et ses potentialités intellectuelles mesurées par une échelle d'intelligence (Q.I.). Il souffre d’un dysfonctionnement des structures cérébrales entravant ses capacités cognitives avec une mauvaise identification des mots. Le diagnostic repose sur l’évaluation de l’habileté de la parole, de la lecture et de l’écriture. Dans ce travail, nous nous sommes intéressés aux enfants présentant une dyslexie phonologique. Cette dernière se caractérise principalement par une altération de la voie phonologique. Ces enfants présentent une sensibilité intracatégorielle supérieure à leur sensibilité intercatégorielle. Si nous acceptons l’hypothèse du couplage entre la perception et la production de la parole, nous pouvons parler d’une perturbation de l’exécution articulatoire de leurs productions qui explique leur retard de parole et leur trouble du langage. En effet, la parole obéit à certaines règles phonétiques et phonologiques ; la variation d’un phonème coarticulé est la source de la difficulté de sa discrimination chez l’enfant dyslexique, car un phonème présente plusieurs allophones. Nous avons supposé que cette variabilité articulatoire d’un seul phonème est la cause principale de leur retard de production et de perception de la parole. De ce fait, nous avons procédé à une analyse de leur production verbale à la recherche des marqueurs articulatoires qui diffèrent de ceux des enfants du groupe de contrôle. Quatre expériences ont été effectuées traitant des séquences de types (CV, CVCV, VCVCV et VCVCCV) en lecture de mots et de pseudo mots, à haute voix et à débit normal. Les paramètres temporels étudiés en ce qui concerne les indices acoustiques pour le segment consonantique ont été pour la consonne occlusive sourde, la durée du VTT, le silence acoustique et le VOT et, pour la consonne occlusive sonore, l’occlusion et le VOT. Nous avons aussi mesuré les segments vocaliques adjacents. Ces différentes analyses révèlent, lors de l’identification de mots, que la voie d’assemblage peut être partiellement opérationnelle chez les enfants dyslexiques, une déformation de mot partielle ou totale, des oppositions de sonorité ou de lieu d’articulation problématiques. A noter aussi des durées segmentales plus élevées chez l’enfant dyslexique que chez l’enfant normo-lecteur traduisant une lenteur dans la progression de la réalisation articulatoire nécessitant une durée supplémentaire. Ces paramètres ne suivent pas souvent une cohérence dans leurs proportions par rapport aux exigences imposées par les caractéristiques du lieu d’articulation et de la qualité du signal. Cependant nous constatons qu’ils peuvent préserver leur intelligibilité. Cette étude expérimentale a permis de mettre en évidence la notion de couplage entre la perception et le trouble articulatoire, voire le retard de la parole et du langage. / Available literature suggests that dyslexia is a learning disability that is neither linked to mental retardation, not to sensory disorder nor to deprived social background. The dyslexic child shows a difference of 18 to 24 months between the academic achievement of a reading subject and his or her intellectual potentials as measured by an intelligence scaling (IQ). The child suffers from brain structure dysfunction which impedes his cognitive abilities resulting in wrong word identification. We also know that the diagnosis is based on the evaluation of speech, reading and writing abilities. In our work, we focus on child phonological dyslexia. The latter is mainly characterized by impaired phonological route due to poor development of phonological ability. In reality, dyslexic children have a higher intra-categorical sensitivity rather than an inter-categorical perception. If we accept the idea of coupling between speech production and perception, we can posit the existence of a perturbation in the articulatory realisation of speech produced by dyslexic children which explains both their delayed speech and language disorder. Indeed, speech is governed by a number of phonetic and phonological rules; the variation of a coarticulated phoneme is at the root of difficulty of phoneme discrimination encountered by dyslexic children. This coarticulated phoneme has several allophones. We suggest that the articulatory variability of a single phoneme is the main cause of speech impairment. We performed an analysis of their verbal production in search of the articulatory markers that differ from children with no learning disability. With this in mind, we conducted four studies dealing with different sequences (CV, CVCV, and VCVCV VCVCCV). Tasks included reading words and pseudo-words, aloud and at normal speech rate. The measured parameters studied as regards acoustic cues for stops were VTT, the acoustic silent phase and VOT for voiceless stops; occlusion and VOT for the voiced stops, and duration for flanking vowels. During word identification, analyses reveal that the phonological route may be partially operational for our subjects. They also reveal partial or total word deformation; voicing contrast and place of articulation contrasts were also affected. Note should be taken of the higher measures found in dyslexic children than in normal readers, reflecting a slower gestures in their articulatory realizations due to additional time needed in these children. In addition, these parameters do not often follow a coherent pattern of proportional values relative to the requirements imposed by the characteristics of place of articulation and signal quality. However, we find that word intelligibility could be maintained. This experimental study has demonstrated the link between perception and articulation disorder, and to some extent speech and language production impairment.

La dynamique spatio-temporelle de l’attention en lecture chez les dyslexiques

Fortier-St-Pierre, Simon 06 1900 (has links)
La dyslexie est un trouble neurodéveloppemental nuisant au développement normal de la fluidité en lecture. Certains processus de base à la lecture pourraient être atteints chez les dyslexiques et entraîner des répercussions touchant les représentations de haut niveau des mots en découlant : orthographique, phonologique et sémantique. Un de ces processus de base est le déploiement spatio-temporel de l’attention sur des séquences de stimuli multiples alignés à l’horizontale. L’efficacité de ce déploiement pourrait être étroitement liée à l’expertise en lecture chez les normo-lecteurs, et des irrégularités dans celui-ci pourraient être observées chez des dyslexiques. Malheureusement, la caractérisation de ce déploiement en contexte de reconnaissance de mots écrits, son implication dans la vitesse de lecture et (potentiellement) même dans certaines habiletés langagières demeurent largement sous-spécifiées. Le premier article de cette thèse vise à révéler les divergences du déploiement de l’attention dans le temps et dans l’espace pendant la reconnaissance d’un mot familier chez un groupe d’adultes dyslexiques par rapport à un groupe de normo-lecteurs. Les groupes sont appariés en termes d’âge et de fonctionnement intellectuel. Cet objectif est poursuivi avec la technique de sonde attentionnelle. Les résultats révèlent que les dyslexiques dirigent moins de ressources attentionnelles vers la première lettre d’un mot, ce qui est sous-optimal considérant que la première lettre d’un mot est particulièrement informative sur son identité. Le deuxième article de cette thèse vise à déterminer si les habiletés en lecture de texte et de traitement phonologique chez les dyslexiques peuvent bénéficier d’un entraînement attentionnel court. Un protocole utilisant un entraînement visuo-attentionnel (NeuroTracker) et un entraînement placebo chez une vingtaine d’adultes dyslexiques met en évidence des gains systématiques immédiatement après l’entraînement actif. L’ordre des entraînements (actif puis placebo, ou placebo puis actif) était contrebalancé entre deux groupes. Ces gains s’observent en vitesse de lecture, et même au niveau de la conscience phonologique. Le troisième article de cette thèse apporte finalement une contribution additionnelle significative pour l’évaluation de la vitesse de la lecture chez les adultes universitaires franco-québécois. L’utilisation des phrases-tests d’un outil existant (MNRead) a été intégrée à un protocole de présentation visuelle sérielle rapide pour l’évaluation de la vitesse de lecture. En plus de cet ensemble de phrases-test, quatre autres ensembles de phrases-test ont été normés. L’outil développé permet d’obtenir une mesure de la vitesse de lecture fiable chez un même individu à différentes reprises (Exp. 1) et il satisfait différents standards psychométriques (Exps. 1 et 2), en étant notamment sensible à la présence des difficultés en lecture retrouvées chez les dyslexiques (Exp. 2). En somme, il appert que certains processus visuo-attentionnels sous-tendent l’expertise en lecture et que ceux-ci pourraient présenter des irrégularités chez les dyslexiques. La caractérisation d’un déploiement attentionnel sous-optimal en reconnaissance de mots familiers tout comme les bénéfices obtenus en lecture et en traitement phonologique subséquents à un entraînement attentionnels mettent en lumière l’importance de ces processus de base en lecture. / Dyslexia is a neurodevelopmental disorder that affects the normal development of reading fluency. Deficits affecting basic reading processes may affect dyslexics and would thus alter high-level word representations: orthographic, phonological, and semantic. One of these basic processes is the attentional mechanism that is involved in the visual processing of horizontal multi-element strings such as words. The effectiveness of this mechanism could be closely related to reading expertise in normal readers and anomalies thereof could be observed in dyslexics. Unfortunately, it remains unclear how attention is deployed during visual word recognition and how it may impact on reading speed and potentially on certain language skills. The first article of this thesis aims to shed light on divergences in the deployment of attention through time and space during the recognition of familiar words in a group of adults with dyslexia in comparison to normal readers. These groups were matched in terms of age and intellectual functioning. This objective is pursued with the attentional probe technique. Results reveal that less attentional resources are directed to the first letter of a word in dyslexics, which is suboptimal considering that the first letter of a word has a higher diagnostic value than any other letter position. The goal of the second article is to determine if reading fluency and phonological awareness in dyslexics may benefit from a short attentional training. The effects of an active training using the NeuroTracker program and a placebo training in adults with dyslexia shows systematic gains immediately after active training. The order of the training (active then placebo, or placebo then active) was counter-balanced across two groups. These gains are observed on reading speed as well as on phonological awareness. The third article of this thesis finally brings a significant additional contribution to the evaluation of reading speed among Quebec university students. The use of test sentences from an existing tool (MNRead) has been incorporated into a rapid visual serial presentation protocol to assess reading speed. In addition to this set of test sentences, four other sets of test sentences have been standardized. The tool is reliable, as reading speed measurements are similar in the same individual at different times (Exp 1). Moreover, it meets different psychometric standards (Exps 1 and 2) while being particularly sensitive to the presence of the reading difficulties found in dyslexics (Exp.2). In sum, it appears that particular visual-attention processes underlie reading expertise and that these show anomalies in dyslexics. The characterization of a suboptimal attention deployment in visual word recognition as well as the benefits obtained in reading and phonological awareness subsequent to an attentional training highlight the importance of these basic processes in reading.

Lärares val av metod i tidig läsinlärning : En intervjustudie av yrkesverksamma lärare i årskurserna F-3

Boberg, Matilda, Ekery, Louise, Eriksson, Linda January 2023 (has links)
Studien belyser läsinlärningens betydande roll för varje elevs läsförmåga, med syfte att undersöka vilka metoder lärare använder i den tidiga läsinlärningen för att elever ska utveckla fonologisk medvetenhet i årskurserna F-3, samt vilka strategier som skapar motivation i läsinlärningen. Det resulterade i frågeställningarna: Vilka metoder och undervisningsmoment i den tidiga läsinlärningen använder lärare inom årskurserna F-3 för att utveckla elevernas fonologiska medvetenhet?  Hur skapar lärare strategier för att underlätta för och motivera elevers läsinlärning? Bakgrund och tidigare forskning presenterar olika läsinlärningsmetoder i syfte att ge läsaren goda kunskaper om forskningsområdet. Semistrukturerade intervjuer med 14 verksamma lågstadielärare ligger till grund för vår empiri. Empirin vägs samman med tidigare forskning i diskussionsdelen och utifrån ett pragmatiskt perspektiv och “lära genom görandet” som teoretiskt perspektiv. Via empirin framkom tre teman; arbete med elevaktiva övningar, lärares struktur på läsundervisningen och lärarnas arbetssätt och mätning gällande progression av avkodningsförmågan. Resultatet visade att samtliga lärare använder olika läsinlärningsmetoder och undervisningsmoment för att skapa kreativa och elevaktiva lektioner, där strategier som rim och ramsor, stavelseträning, kooperativa övningar, Bornholmsmodellen, Fonomix och andra språklekar innefattas. Genom att utveckla den fonologiska medvetenheten förbättrades elevernas läsflyt. Studien visade att lärarna inte använder endast en läsinlärningsmetod, utan valde ut delar av metoderna som de ansåg vara mest framgångsrika och givande för eleverna. Genom att lärarna arbetade varierat och använde mycket repetition i undervisningen skapades glädje och motivation, vilket ledde till att eleverna utvecklade ett intresse genom att de fick vara delaktiga i sin egen utveckling av den fonologiska medvetenheten. / The purpose of this study was to highlight the significant role that learning how to read has in each pupil's life. This study aims to examine which methods teachers use in grades F-3, when the pupils are learning how to read, to get them to be skillful readers and form phonological awareness. The study also examines which strategies teachers use to motivate early reading. This resulted in the questions: What methods and tools do teachers use in grades F-3, when pupils are learning to read and develop their phonological awareness? How teachers use strategies to aid and motivate pupils' early reading ability? The study is based on semi-structured interviews with fourteen working primary school teachers. The study holds a pragmatic perspective, with “learning by doing” as a theoretical perspective. Through the analysis of the empirical data three themes emerged: teaching with pupil active exercises, teacher's structure of reading instruction and how teachers work and measure the progression of pupils' decoding skills. The study concluded that all teachers use different reading strategies and teaching tools to create creative and pupil engaged lessons, where work with rhymes, syllable training, cooperative exercises, the Bornholm model, Fonomix and other language games are included. When phonological awareness has developed, pupils showed better reading fluency and higher results in reading exercises. The study shows that the teachers do not only use one method when the pupils are learning to read. Instead, teachers selected parts of different methods that they consider to be the most successful, effective, and most rewarding exercises for the pupils. Because the teachers worked variedly and used a lot of repetition, joy and motivation were created, which led to the students developing an interest by being able to participate in their own development of phonological awareness.
