Este trabalho teve como escopo detectar mecanismos presentes no processo de produção escrita de alunos que chegam ao sexto ano do Ensino Fundamental sem o domínio ortográfico esperado nesse nível de escolaridade, considerando o sexto ano como momento nodal para um apoio fundamentado àqueles que apresentem defasagem. Para tanto, analisa produções de quatro alunos de uma escola pública estadual da capital paulista, com base em postulados da Fonética e da Fonologia, em que são observadas as possíveis relações entre a consciência fonológica do português brasileiro e os processos de escrita. Reflexões da Psicolinguística concorrem para o entendimento de que os erros dos alunos são índices a serem considerados para intervenção didático-pedagógica. Para sintonizar intervenções na escola, postulados da Teoria da Atribuição Causal, voltados para a educação, são propostos com o intuito de compreender a disposição dos alunos diante das dinâmicas de ensino e aprendizagem. Uma sistematização das normas ortográficas do português embasa sugestões de abordagens em sala de aula para superação dos problemas apontados. / This dissertation aims to describe the mechanisms involved when sixth-grade students do not achieve expected levels in orthography. The sixth-grade is considered a critical time to provide appropriate support for those students who are under-achieving. Psycholinguistics have postulated that student errors are indicators of the need for pedagogical didactic intervention. The study analyses the written work of four students from a public school in the State of Sao Paulo, from a Phonetic and Phonologic perspective. A relationship between phonological awareness of Brazilian Portuguese and writing processes was observed. To understand the engagement of students with teaching and learning, the Attribution Theory is suggested in order to adjust school interventions. A system of Portuguese orthographic norms was part of the research, along with suggestions for practical intervention.

L’objectif de cette thèse était d’étudier les variations possibles des processus impliqués dans la reconnaissance visuelle des mots selon les différences d’habiletés lexicales de lecteurs adultes (niveaux de lecture, orthographe et vocabulaire). Ainsi, nous avons testé l’effet de fréquence du voisinage orthographique par suppression et par substitution d’une lettre dans des tâches de décision lexicale (Exp. 1, 4), démasquage progressif (Exp. 2, 5), dénomination (Exp. 3, 6), et catégorisation de couleur (Exp. 7). Un effet inhibiteur de fréquence du voisinage orthographique par suppression (Exp. 1-3) et par substitution (Exp. 6) d’une lettre a été obtenu. Les temps de réponse étaient plus longs et les taux d’erreurs plus élevés pour les mots avec au moins un voisin orthographique plus fréquent que pour ceux sans un tel voisin, ce qui peut être expliqué en termes de compétition lexicale. De plus, la compétition lexicale du voisin par suppression d’une lettre était plus importante pour les individus ayant des habiletés lexicales hautes plutôt que basses (Exp. 1, 3), ces derniers individus témoignant de difficultés d’inhibition du compétiteur. Par ailleurs, les individus ayant des habiletés lexicales basses étaient moins rapides et moins précis que ceux ayant des habiletés lexicales hautes (Exp. 1-7). Les données de la tâche de catégorisation (Exp. 7) suggèrent des difficultés dans la mise en place de l’inhibition pour ces individus. Enfin, nous avons montré que l’effet de fréquence du voisinage orthographique était influencé par la confusabilité de la lettre substituée, ce qui différait selon les habiletés lexicales des individus (Exp. 4-6). Dans le cadre théorique de l’activation interactive et de codage spatial des lettres, les données soulignent l’importance des différences d’habiletés lexicales des lecteurs pour rendre compte des différences dans la diffusion de l’activation et de l’inhibition lexicales dans la reconnaissance visuelle des mots. / Word recognition, according to the adult readers’ lexical skill differences (reading, spelling and vocabulary levels). To do so, we tested the orthographic neighborhood frequency effect by deletion and substitution of a letter in lexical decision (Exp.1, 4), progressive demasking (Exp 2, 5), denomination (Exp. 3, 6), and color categorization tasks (Exp.7). Response times were longer and the error rates were higher for words with at least one higher frequency neighbor than for words without such a neighbor, which can be explained in terms of lexical competition. In addition, the lexical competition of the higher-frequency deletion neighbor seems more important for individuals with high lexical skills than for those with low lexical skills (Exp 1, 3), the latter showing difficulties in inhibiting the competitor. Furthermore, individuals with low lexical skills were slower and less accurate than those with high lexical skills (Exp 1-7). Data from the categorization task (Exp. 7) suggest difficulties in setting up inhibition for these individuals. Finally, we have shown that the orthographic neighborhood frequency effect was influenced by the confusability of the substituted letter, differing according to the lexical skills of the individuals (Exp 4-6). In the theoretical framework of activation-interactive and spatial coding, the data highlight the importance of readers’ differences in lexical skills for the diffusion of lexical activation and inhibition in visual word recognition.

Learning to see allows the student to understand the formation of projections and return to the practice of observation. Three-dimensional visualization produces recognition of the projected image. The development of this learning cannot be restricted to study based only on programmed handouts with forms or feedback solutions.This Design-Based Research developed and implemented a system of security cameras to aid in visualization. This innovation provided for the construction of an educational experience that fosters collaborative learning through interaction with three-dimensional models of the objects to be represented in graphic drawings. The proposal to investigate the practice of graphic representation and strategies for development of this graphic language was carried out with students, aged between 14 and 17 years, in high school at a state technical school. Data collection was done by the researcher in research logs, activities proposed in class and recordings from security cameras positioned to capture the image ?pura. Results underline the importance of creating an educational process applied to technical drawing that develops the act of the careful observation and integration of objects and images with the main aspects of projective drawing. This enables the learning of the concepts of descriptive geometry and facilitates the visualization of the trihedral system and the design of the principal orthographic views (front, top and side) utilizing varied teaching strategies / O processo de aprendizagem dos estudos introdut?rios, do sistema projetivo ortogonal e de elementos constituintes (ponto, reta e plano), estudados em Geometria Descritiva por alunos do Ensino M?dio de cursos de forma??o t?cnica, encontra dificuldade no desenvolvimento da vis?o espacial e da representa??o gr?fica.

The current study aimed to develop a model of reading comprehension for children in middle primary school. As part of this overall aim there was a particular focus on the contribution of different types of memory to reading comprehension. The variables selected for consideration were identified from the child and adult literature and were of three types: word reading, language, and memory. The sample comprised 180 primary school children in grades 3-5 recruited from two primary schools. Their ages ranged from 8 years 7 months to 11 years 11 months. The reading comprehension measure was in a multiple-choice format with the text available when answering the questions. The five word reading measures were phonological recoding, orthographic processing, text reading accuracy, text reading speed, and a measure of exposure to print and reading experience. It is recognised that, although exposure to print is closely associated with word reading skills, it is not a direct measure of word reading. The language measures were oral comprehension, receptive vocabulary and receptive grammatical skills. The memory measures included measures of verbal and visuospatial short-term memory, measures of verbal and visuospatial working memory, a measure of the ability to inhibit irrelevant information from working memory and a measure of longer term verbal learning and retrieval. Correlational and hierachical multiple regression analyses were used to extrapolate the relationships between and among these variables. The results revealed that, after controlling for age and general intellectual ability, the word reading and the language variables had a much stronger relationship with reading comprehension than the memory variables. The strongest independent predictors of reading comprehension were orthographic processing and oral comprehension. An additive combination of these two variables provided a more parsimonious model of reading comprehension than other models under consideration. It was concluded that for the age range in this study, language and word reading skills are the main predictors of reading comprehension and that the different types of memory do not make major contributions to reading comprehension.

<p>The general aim of this thesis was to investigate phonological processing skills in dyslexic children and adults and their relation to speech perception. Dyslexia can be studied at various levels: at a biological, cognitive and an environmental level. This thesis mainly looks at environmental and cognitive factors. It is a commonly held view that dyslexia is related to problems with phonological processing, that is, dyslexics have problems dealing with the sound structure of language. The problem is for example seen in tasks where the individual has to manipulate sound segments in the spoken language, read non-words, rapidly name pictures and digits, keep verbal material in short-term memory, and categorize and discriminate sound contrasts in speech perception. To fully understand the dyslexic’s problems we have to investigate both children and adults since the problems might change during the lifespan as a result of changes in the language system and compensatory mechanisms in the poor reader. Research indicates that adult dyslexics can reach functional reading proficiency but still perform poorly on tasks of phonological processing. Even though they can manage many everyday reading situations problems often arise when adult dyslexics enter higher education. The phonological problems of dyslexics are believed to be related to the underlying phonological representations of the language. The phonological representations have been hypothesized to be weakly specified or indistinct and/or not enough segmented. Deviant phonological representations are believed to cause problems when the mapping of written language is to be made to the phonological representations of spoken language during reading acquisition. In Paper 1 adults’ phonological processing and reading habits were investigated in order to increase our understanding of how the reading problems develop into adulthood and what the social consequences are. The results showed that adult dyslexics remained impaired in their phonological processing and that they differed substantially from controls in their choices regarding higher education and also regarding reading habits. Paper 2 reviews research that has used the sine wave speech paradigm in studies of speech perception. The paper also gives a detailed description of how sine wave speech is made and how it can be characterized. Sine wave speech is a course grained description of natural speech lacking phonetic detail. In Paper 3 sine wave speech varying with regard to how much suprasegmental information it contains is employed. Results showed that dyslexics were poorer at identifying monosyllabic words but not disyllabic words and a sentence, plausibly because the dyslexics had problems identifying the phonetic information in monosyllabic words. Paper 4 tested dyslexics’ categorization performance of fricative-vowel syllables and the results showed that dyslexics were less consistent than controls in their categorization indicating poorer sensitivity to phonetic detail. In all the results of the thesis are in line with the phonological deficit hypothesis as revealed by adult data and the performance on task of speech perception. It is concluded that dyslexic children and adults seem to have less well specified phonological representations. </p>

This thesis examined the role of metalinguistic skills in concurrent and subsequent word-level reading and oral vocabulary among Chinese-English bilingual children who learned Chinese as their heritage language and English as their societal language. While previous studies on biliteracy development among this group of children have mostly focused on one of the two languages, this thesis gave equal emphasis to both languages. The research had two general purposes: 1) to investigate the role of phonological awareness, morphological awareness and orthographic processing in predicting word-level reading and oral vocabulary in Chinese and English concurrently and longitudinally; and 2) to examine the cross-linguistic role of phonological and morphological awareness to word-level reading and vocabulary, concurrently and longitudinally, between Chinese and English. These goals were explored through two interrelated studies, using path analyses. The participants included 91 Chinese-English bilingual children, recruited from kindergarten and Grade 1 Chinese heritage language classes in Canada. They were tested twice, one year apart, on a battery of cognitive and literacy measures in Chinese and English. Findings of Study 1 on within-language relationships indicated that, for word-level reading, all three metalinguistic skills were independent concurrent predictors in English, whereas only morphological awareness was predictive in Chinese. For oral vocabulary, morphological awareness was the only concurrent predictor in both languages. The longitudinal contributions of these metalinguistic skills were mostly mediated through the auto-regressors of the literacy outcomes. Findings of Study 2 on between-language relationships demonstrated that Chinese phonological awareness directly contributed to concurrent and subsequent English word reading beyond the effect of concurrent English phonological awareness. Yet, Chinese morphological awareness indirectly predicted concurrent and subsequent English oral vocabulary through concurrent English morphological awareness. Similarly, English morphological awareness only indirectly predicted concurrent and subsequent Chinese oral vocabulary. These findings suggest that different metalinguistic skills are required for literacy development in Chinese and English. Moreover, metalinguistic skills transfer to literacy, even across two typologically distant languages, but the transfer patterns of phonological and morphological awareness to different literacy skills vary considerably. These results are discussed in light of current reading and transfer models as well as linguistic contexts of biliteracy acquisition.
