The identification of early factors related to academic achievement among deaf students

The purpose of this research study was to examine specific factors believed to be related to academic achievement in deaf children. More specifically, this research sought to determine whether there was a significant difference in achievement between those students whose parents use oral communication only and those whose parents use some type of sign language. An additional purpose of this research was to determine if there was a significant difference in academic achievement with those deaf students who used amplification devices early in life. This study also sought to determine whether providing early intervention program which emphasizes and enables parents to develop a language rich environment had a significant impact on the academic achievement of deaf children and whether the age at which initial services are received influence deaf student's subsequent academic achievement. This study examined the relationship, if any, between intellectual ability and academic achievement among deaf children. Finally, this study sought to investigate the relationship between the degree of hearing loss and academic achievement. ^ Purposive sampling was used to select subjects for this study. All 228 eligible Deaf/Hard of Hearing (DHH) students enrolled in a Broward County Public School were included in the original sample. Sixty-one students actually participated in this study. A correlational method of statistical analysis as well as a cross classification (crosstabs) was used to analyze the data. ^ The results show that academic achievement in the areas of reading and mathematics was significantly related to parental mode of communication and the mode of communication used in school. Academic achievement, in the area of reading, was also signficantly related to intellectual ability. The reading achievement was also found to be significantly related to degree of hearing loss. Written language was not significantly related to any factors investigated in this study. ^ Additional research should be conducted to further investigate the low academic achievement among deaf children. The diversity among signing systems at school and between home and school should also be analyzed. Finally, future studies should examine curriculum and instruction methods to increase the academic achievement of deaf children. ^

DEAF INDIVIDUALS USERS OF SIGN LANGUAGE LEARNING PORTUGUESE: THE ANALYSIS OF PRACTICAL CLASSES

This essay shows the report of a series of searches that deal the acquisition of a first and a second language by deaf children, in inclusive contexts. Due to hearing deprivation, and for not having a whole acoustic duct, deaf people end up not acquiring naturally the language that is common for Brazilians in general. Among the searches carried out, those that deal the written expression of deaf undergraduates, whose path in the acquisition of the language(s) did not follow the model prescribed by current theoreticians. The search shows that the analyzed students did not acquire sign language as first language in the first phase of childhood and Portuguese as second language, contradicting the bilingual model adopted in Brazil

语前聋小儿人工耳蜗植入术后的言语康复

An Approach to the Rehabilitation of Prelingually Deaf Children After Cochlear Implantation Zheng Xiujin(Medical Psychology) Directed by Professor Yin WenGang Abstract Objective: To sum up the acquirement rule of speech and language capability which is for the prelingually deaf children after cochlear implantation by listening and language rehabilitation training and to investigate the factors that affect rehabilitation speed. Method: Sixty-four children received a cochlear implant at the age of 2 to 5 years from 2001 to 2005. They begin to be trained under group pattern after switch on 1 month. The whole training program lasted more than 7 months; after that, according to the teacher’s plan the training program was to be continued at home. Result: The period is 108±7.7 days that they can pronounce correctly 50 percent of all of simple-finals and compound-finals, the period is 115.0±7.8 days that they begin auditory repeating, the period is 135.3±10.9 days that they can speech the first specific word independently and the period is 200.3±13.9 days that they can speak 70 words and come into tri-gamut-word and two-word sentence period. The patient that is the group at the age of 2-3 years can take part in normal kindergarten after switch on about 10 months. There are no significant differences in various grades of speech-language development with different age groups and so do with different sex groups. There are significant differences in various grade of speech-language development with various IQ group (P<0.01) and so do with using and not using hearing aids before implantation. Conclusion: From the research we find that the speech and language development sequence is the same level between the prelingually deaf children of 2 to 5 years who received cochlear implant after speech training and normal children and which are stages of uncomplicated sound production, continuous syllabic (babbling), speech sprout, single-word utterances and two-word utterances in proper order. The time is short significantly and the reason is that cognition capability is enhanced along with the increase of age. The intelligence is main factor that affect rehabilitation speed and the speed in the group of high IQ is faster than common IQ. It is not because of the dominance cognition of the senior group that makes the increasing of the rehabilitation, it even makes slowly. The reason of which is that the senior group are exposed the language environment too late to achieve speech and language development. So we should perform an operation and training early. The effectiveness of rehabilitation after cochlear implantation is improved by using hearing aids before implantation. The reason is auditory stimulate can be benefit of to deaf children. The rehabilitation speeds in the children at the age of 2 to 5 years have nothing to do with sex. Key words: cochlear implant; speech therapy; paediatric rehabilitation

What is universal and what differs in language development?

Goldin-Meadow (2015) presents an exceptional synthesis of work from studies of children acquiring language under variable circumstances of input or processing abilities. Deaf children who acquire homesign without any well- formed model from which to learn language represent a powerful example. Goldin-Meadow argues that the resilient properties of language that nevertheless emerge include simple syntactic structures, hierarchical organisa- tion, markers modulating the meaning of sentences, and social-communicative functions. Among the fragile or input-dependent properties are the orders that the language follows, the parts into which words are decomposed, and the features that distinguish nominals from predicates. Separation of these two types of properties poses questions concerning the innate constraints on language acquisition (perhaps these equate to the resilient properties) and con‐ cerning the specificity of processes to language (e.g., whether properties such as hierarchical organisation are specific to language or originate in the structure of thought). The study of the resilient properties of human language in the face of adversity and the relation of these properties to the information that is encoded in the human genome represent a research strategy that draws inferences about species universals (properties that all humans share) from data about individual differences (IDs; factors that make humans different from one another). In the following, we suggest three reasons to be cautious about this approach.

Développement des habiletés linguistiques chez les enfants porteurs d'un implant cochléaire

Cette thèse examine le développement du langage des enfants sourds qui ont reçu un implant cochléaire (IC) en bas âge. Une première étude rapporte une revue systématique qui avait pour but d’évaluer les connaissances actuelles concernant le développement du vocabulaire et de la grammaire chez les enfants qui ont reçu un IC avant l’âge de trois ans. Vingt-huit études ont été sélectionnées; une analyse descriptive de même qu’une méta-analyse ont été effectuées séparément pour chaque aspect du langage évalué (vocabulaire et grammaire, aspect réceptif et expressif). Au résultat, en dépit de la variabilité observée dans les études, il appert que l’implant cochléaire influence positivement le développement langagier; toutefois, seule une minorité de participants aux études a atteint des niveaux de langage comparables à ceux d’enfants entendants de même âge chronologique. La majorité des enfants continuent de présenter divers degrés de retard de langage, tant au plan réceptif qu’expressif, et ce, après jusqu’à cinq années de port de l’appareil. Les résultats suggèrent aussi, malgré la variabilité observée dans les études, que les bénéfices langagiers sont influencés par le fait de recevoir l’implant à deux ans plutôt qu’à trois ans. À partir des tendances retrouvées dans la littérature, les habiletés de vocabulaire et de grammaire chez 27 enfants qui ont reçu l’implant cochléaire en bas âge (entre 8 et 28 mois) ont été comparées avec celles d’un groupe d’enfants entendants, en utilisant des outils d’évaluation standardisés. Alors que les résultats de groupe montrent que les enfants qui reçoivent un IC autour de l’âge de deux ans atteignent des niveaux de langage dans les limites de la normale, les résultats individuels d’un sous-groupe formé de enfants les plus âgés font état de quatre profils de développement, soit des niveaux de langage dans les limites de la normale pour l’ensemble des composantes, un retard généralisé à l’ensemble des composantes, des habiletés lexicales dans la norme assorti d’un retard morphosyntaxique et enfin un profil atypique montrant des disparités importantes à travers les composantes du langage. Dans trois des quatre profils, la compréhension des phrases était particulièrement faible. Ces résultats suggèrent que le fait de recevoir un implant cochléaire entre l’âge d’un et deux ans ne garantit pas l’atteinte de niveaux de langage dans les limites de la normale malgré une expérience de port de l’appareil d’une durée appréciable. Une étape antérieure du développement linguistique a été examinée de plus près dans la troisième étude. La taille et la composition du vocabulaire expressif de onze enfants ayant reçu un IC à un âge moyen de 15 mois ont été comparées à celles de l’échantillon d’enfants entendants ayant servi à établir les normes en français québécois pour le questionnaire Mots et énoncés des Inventaires MacArthur-Bates du développement de la communication (IMBDC). Les scores d’âge équivalent selon la taille totale du vocabulaire des enfants avec IC étaient supérieurs à l’âge auditif (correspondant à la durée de port de l’appareil) mais inférieurs à l’âge chronologique. La représentation grammaticale en fonction de la taille du vocabulaire des enfants avec IC suit la tendance observée dans la norme. Ces résultats suggèrent que le profil lexical des enfants avec implant est très similaire à celui des enfants entendants lorsque le nombre total de mots acquis est le même. Les résultats de cette thèse suggèrent que l’implant peut, de manière générale, avoir un effet « normalisant » sur le langage ; toutefois, il semble que l’amélioration de l’accès auditif ne suffise pas pour rattraper à coup sûr le niveau de langage des pairs entendants dans l’ensemble des composantes du langage. Alors que les habiletés lexicales se rapprochent du profil typique, les habiletés de compréhension morphosyntaxique sont fortement atteintes chez une majorité d’enfants, suggérant un profil apparenté à un trouble de langage.

A narrativa em crianças surdas : papel da Língua Gestual Portuguesa

A presente pesquisa tem como Questão Central a avaliação da estrutura da narrativa por um grupo de seis crianças surdas profundas utilizando a Língua Gestual Portuguesa (LGP). Neste estudo questionou-se se se encontrariam diferenças na produção da narrativa entre crianças que adquiriram a LGP precocemente e as que tiveram o primeiro contato com a língua materna tardiamente. Colocou-se a hipótese geral que a língua natural das crianças surdas portuguesas é a LGP e as que tiveram um acesso precoce à sua língua apresentam um melhor desempenho na narração de uma história. Para verificar esta hipótese, foi aplicada uma prova que consistia no conto de uma história, a partir de uma sequência de imagens, em LGP a todos as crianças desta investigação. Releva-se a importância de um precoce ambiente comunicativo para que a criança surda adquira um desenvolvimento global semelhante aos seus pares ouvintes. Salienta-se ainda que a influência dos pais, dos educadores e dos professores é fundamental para que a criança surda possa desenvolver a sua língua natural, a LGP e a aprendizagem da segunda língua. Os resultados obtidos confirmaram as hipóteses colocadas, ou seja, as crianças que adquiriram precocemente a LGP apresentaram um maior desenvolvimento na estrutura da narrativa.

Aprendizagem de escrita de língua de sinais pelo sistema SignWriting : língua de sinais no papel e no computador

Esta tese trata de como o sistema SignWriting pode servir de suporte a uma nova proposta pedagógica ao ensino da escrita de língua de sinais e letramento para crianças surdas usuárias da Língua Brasileira de Sinais - Libras e da Língua de Sinais Francesa - LSF. Escrever deve ser uma atividade significativa para a criança. No caso da criança surda, a escrita fundamenta-se em sua competência na língua de sinais, sem precisar da intermediação da língua oral. A criança surda, quando em um ambiente onde ela e seus colegas se comunicam em língua de sinais, efetivamente tenta escrever sinais, quando é incentivada a fazê-lo. Em nossos experimentos, usamos o sistema SignWriting para mostrar ás crianças surdas (e a seus pais e professores) como escrever textos em línguas de sinais de ambas as formas: manuscrita e impressa, usando o programa Sign Writer para editar textos em línguas de sinais. A base teórica que apóia a tese é a abordagem bilíngüe para a educação de surdos, a língua de sinais, a teoria de Piaget, e de Ferreiro quando trata das etapas da alfabetização em língua oral. Esta investigação possui um caráter exploratório, em que o delineamento metodológico é dado pela pesquisa-ação. O primeiro estudo apresenta um levantamento do processo de aquisição da escrita de sinais, em sua forma manuscrita, pela criança e jovem surdo no Brasil e na França. O segundo estudo trata da ajuda que a informática pode dar a essa aquisição e de como utilizamos os softwares de escrita de língua de sinais em aulas de introdução ao uso do computador e em transcrições da LSF de corpus vídeo para a escrita de língua de sinais. Os resultados sugerem que as crianças evoluem em sua escrita, pois muitos signos que elas escreveram não foram sugeridos pela experimentadora, nem por outro meio, mas surgiram espontaneamente. A introdução de um software como o Sign Writer ou o SW-Edit nas classes para introduzir as TI traz a essas aulas muito maior interesse do que quando usamos um editor de textos na língua oral. Também as produções das crianças são mais sofisticadas. As conclusões indicam que a escrita de língua de sinais incorporada à educação das crianças surdas pode significar um avanço significativo na consolidação de uma educação realmente bilíngüe, na evolução das línguas de sinais e aponta para a possibilidade de novas abordagens ao ensino da língua oral como segunda língua.

Medidas operantes de limiar auditivo em crianças com surdez pré-lingual, usuárias de implante coclear

Limiares auditivos de crianças surdas pré-linguais usuárias de implante coclear foram avaliados com estimulação elétrica em um dos eletrodos mediais. A avaliação empregou um procedimento operante do tipo go/no go para ensinar uma discriminação simples, evidenciada por uma resposta motora, entre presença e ausência do estímulo auditivo. Estabelecida a linha de base, a manipulação na intensidade do estímulo foi implementada de acordo com o método psicofísico de escada modificado, começando por uma seqüência descendente. Os sete participantes do estudo mostraram perda da precisão no responder sob controle do estímulo quando a intensidade diminuía além de um certo valor e a precisão era recuperada quando a intensidade era novamente aumentada, o que permitiu a identificação de limiares individuais. Os resultados sugerem que o método psicofísico combinado com o procedimento operante pode ser uma alternativa viável para avaliar limiar auditivo de pessoas sem linguagem em situação clínica de regulagem do implante coclear.
