Habilidades de processamento fonológico e de escrita em crianças com distúrbio específico de linguagem: um estudo comparativo com a normalidade

Introdução: Crianças com distúrbio específico de linguagem (DEL) são propensas a apresentar dificuldade no processo de alfabetização devido às múltiplas alterações de linguagem que possuem. Este estudo comparou e caracterizou o desempenho de crianças com DEL e em desenvolvimento típico de linguagem em atividades de aliteração, rima, memória de curto prazo fonológica, ditado de palavras e de pseudopalavras. A principal hipótese do estudo era de que o grupo DEL apresentaria desempenho inferior do que o grupo em desenvolvimento típico em todas as habilidades estudadas. Método: Participaram do estudo 12 crianças com DEL (GP) e 48 em desenvolvimento típico (GC) com idade entre 7 anos e 9 anos e 11 meses. Todos os sujeitos cursavam o 2º ou 3º ano do ensino fundamental I e apresentavam audição e rendimento intelectual não-verbal preservados. Para a seleção dos grupos foram utilizadas medidas de vocabulário receptivo, fonologia e nível socioeconômico. Já as medidas experimentais avaliadas foram testes padronizados de aliteração, rima, memória de curto prazo fonológica e a aplicação de um ditado de palavras e de pseudopalavras elaborados para esta pesquisa. Resultados: ambos os grupos apresentaram pior desempenho em tarefas de rima do que de aliteração e o GP apresentou desempenho inferior em ambas as tarefas quando comparado ao GC. A análise dos distratores nas atividades de aliteração e rima apontou que em tarefas de aliteração, o GP cometeu mais erros de tipologia semântico enquanto na prova de rima foram mais erros de tipologia fonológico. O GP obteve desempenho inferior ao GC nas avaliações da memória de curto prazo fonológica, ditado de palavras e de pseudopalavras. O GP evidenciou maior dificuldade no ditado de pseudopalavras no que no de palavras e o GC não apresentou diferença significativa no desempenho dos ditados. No ditado de palavras, o GP cometeu mais erros na palavra toda enquanto no ditado de pseudopalavras ocorreram mais erros na palavra toda e na sílaba final. Na comparação do desempenho dos grupos de acordo com a escolaridade, notou-se que os sujeitos do GC do 2º e 3º ano não evidenciaram diferença significativa em seu desempenho nas tarefas, enquanto os sujeitos do GP do 3º ano apresentaram melhor desempenho do que os do 2º ano em todas as medidas experimentais, com exceção da memória de curto prazo fonológica. Conclusões: o GP apresentou dificuldade em tarefas de processamento fonológico e de escrita que foram realizadas com relativa facilidade pelo GC. Os sujeitos com DEL evidenciaram uma análise mais global dos estímulos apresentados nas tarefas de consciência fonológica, o que os fez desprezar aspectos segmentais importantes. A dificuldade em abordar as informações de modo analítico, somado a alterações linguísticas e do processamento fonológico, levou o GP a apresentar maior taxa de erros nas tarefas de ditado. Apesar das alterações apontadas, os sujeitos do GP do 3º ano obtiveram melhor desempenho do que os do 2º ano em todas as habilidades com exceção da memória de curto prazo fonológica, que é sua marca clínica. Estes dados reforçam a necessidade do diagnóstico e intervenção precoces para esta população, onde as habilidades abordadas neste estudo devem ser incluídas no processo terapêutico

Symptoms and diagnosis of borderline, early and advanced epithelial ovarian cancer

Objective. To document symptoms associated with borderline, early and advanced ovarian cancer and identify personal characteristics associated with early versus late diagnosis. Methods. Information concerning symptoms and diagnosis history was available from 811 women with ovarian cancer who took part in an Australian case–control study in the early 1990s. Women were classified into three groups for comparison based on their diagnosis: borderline, early (stage I–II) and advanced (stage III–IV) invasive cancer. Results. Sixteen percent of women with borderline tumors, 7% with early cancer and 4% with advanced cancer experienced no symptoms before diagnosis (P < 0.0001). Among women with symptoms, abdominal pain (44%) or swelling (39%) were most frequently reported; an abdominal mass (12%) and gynecological symptoms (12%) were less common. Compared to advanced stage cancer, women with early stage cancer were more likely to report an abdominal mass or urinary symptoms but less likely to report gastrointestinal problems or general malaise. General malaise and ‘other’ symptoms were least common in borderline disease. Older women, and those with higher parity or a family history of breast or ovarian cancer, were more likely to be diagnosed at an advanced stage of disease. Conclusions. Women who experience persistent or recurrent abdominal symptoms, particularly swelling and/or pain should be encouraged to seek medical attention and physicians should be alert to the possibility of ovarian cancer even in the absence of an abdominal mass. Further information about the prevalence of these symptoms in the general population is essential to assist physicians in patient management.

Unresolved issues and new challenges in teaching English to young learners:the case of South Korea

The introduction of languages, especially English, into the primary curriculum around the world has been one of the major language-in-education policy developments in recent years. In countries where English has been compulsory for a number of years, the question arises as to what extent the numerous and well-documented challenges faced by the initial implementation of early language learning policies have been overcome and whether new challenges have arisen as policies have become consolidated. This article therefore focuses on South Korea, where English has been compulsory in primary school since 1997. The issues raised by the introduction of English into the primary curriculum are reviewed and the current situation in South Korea is investigated. The results of a mixed methods study using survey data from 125 Korean primary school teachers, together with data from a small-scale case study of one teacher are presented. The study shows that, while some of the initial problems caused by the introduction of early language learning appear to have been addressed, other challenges persist. Moreover, the data reveal the emergence of a number of new challenges faced by primary school teachers of English as they seek to implement government policy. © 2013 © 2013 Taylor & Francis.

Vocabulary learning through use of the picture-word inductive model for young English learners in China: A mixed methods examination using Cognitive Load Theory

English has been taught as a core and compulsory subject in China for decades. Recently, the demand for English in China has increased dramatically. China now has the world's largest English-learning population. The traditional English-teaching method cannot continue to be the only approach because it merely focuses on reading, grammar and translation, which cannot meet English learners and users' needs (i.e., communicative competence and skills in speaking and writing). ^ This study was conducted to investigate if the Picture-Word Inductive Model (PWIM), a new pedagogical method using pictures and inductive thinking, would benefit English learners in China in terms of potential higher output in speaking and writing. With the gauge of Cognitive Load Theory (CLT), specifically, its redundancy effect, I investigated whether processing words and a picture concurrently would present a cognitive overload for English learners in China. ^ I conducted a mixed methods research study. A quasi-experiment (pretest, intervention for seven weeks, and posttest) was conducted using 234 students in four groups in Lianyungang, China (58 fourth graders and 57 seventh graders as an experimental group with PWIM and 59 fourth graders and 60 seventh graders as a control group with the traditional method). No significant difference in the effects of PWIM was found on vocabulary acquisition based on grade levels. Observations, questionnaires with open-ended questions, and interviews were deployed to answer the three remaining research questions. A few students felt cognitively overloaded when they encountered too many writing samples, too many new words at one time, repeated words, mismatches between words and pictures, and so on. Many students listed and exemplified numerous strengths of PWIM, but a few mentioned weaknesses of PWIM. The students expressed the idea that PWIM had a positive effect on their English teaching. ^ As integrated inferences, qualitative findings were used to explain the quantitative results that there were no significant differences of the effects of the PWIM between the experimental and control groups in both grade levels, from four contextual aspects: time constraints on PWIM implementation, teachers' resistance, how to use PWIM and PWIM implemented in a classroom over 55 students.^

Avaliação do Processo de Ensino e Aprendizagem em Matemática: contribuições da teoria histórico-cultural

This article presents the results of a study that investigated the meaning of evaluation in mathematics from the historical cultural perspective, focusing on activity theory. In order to develop the investigation, a collaborative group was formed from the Oficina Pedagogica de Matematica de Ribeirao Preto - Sao Paulo (Math Pedagogic Workshop of Ribeirao Preto - OPM/RP), constituted of pre-school teachers and early elementary school teachers, who were participants in this research. The main role of the collaborative group was to offer guided development to the teachers about the teaching of mathematics from the historical-cultural perspective, aiming at collecting data on the process of appropriation of mathematical knowledge by the teachers. The syntheses about the teachers' learning process have contributed to systematize the guiding elements of evaluation in mathematics from the historical-cultural perspective.

Boys performing English

This article explores the gender dynamics of boys' responses to one Particular aspect of English teaching. oral performance work. It focuses on the possibility that the requirement to perform publicly in dramatic and other oral tasks may be an important factor in the rejection of English by many boys, and may contribute to boys' relatively poor achievement in English. The article provides a study of boys' engagement in English oral activities in two classrooms, and identifies a number of factors influencing boys' English learning. In particular, it shows that there is no simple relation between the performance requirements of English learning activities and boys' disengagement with English.

Clinical End Points and Response Criteria in Mycosis Fungoides and Sezary Syndrome: A Consensus Statement of the International Society for Cutaneous Lymphomas, the United States Cutaneous Lymphoma Consortium, and the Cutaneous Lymphoma Task Force of the European Organisation for Research and Treatment of Cancer

Mycosis fungoides (MF) and Sezary syndrome (SS), the major forms of cutaneous T-cell lymphoma, have unique characteristics that distinguish them from other types of non-Hodgkin`s lymphomas. Clinical trials in MF/SS have suffered from a lack of standardization in evaluation, staging, assessment, end points, and response criteria. Recently defined criteria for the diagnosis of early MF, guidelines for initial evaluation, and revised staging and classification criteria for MF and SS now offer the potential for uniform staging of patients enrolled in clinical trials for MF/SS. This article presents consensus recommendations for the general conduct of clinical trials of patients with MF/SS as well as methods for standardized assessment of potential disease manifestations in skin, lymph nodes, blood, and visceral organs, and definition of end points and response criteria. These guidelines should facilitate collaboration among investigators and collation of data from sponsor-generated or investigator-initiated clinical trials involving patients with MF or SS.

The Interactive Whiteboard And Language Learning: A Case Study

In this paper, we intend to present some research carried out in a state Primary school, which is very well-equipped with ICT resources, including interactive whiteboards. The interactive whiteboard was used in the context of a Unit of Work for English learning, based on a traditional oral story, ‘Jack and the Beanstalk’. It was also used for reinforcing other topics like, ‘At the beach’, ‘In the city’, ‘Jobs’, etc. An analysis of the use of the digital board, which includes observation records as well as questionnaires for teachers and pupils, was carried out.

Notch1 control of oligodendrocyte differentiation in the spinal cord.

We have selectively inhibited Notch1 signaling in oligodendrocyte precursors (OPCs) using the Cre/loxP system in transgenic mice to investigate the role of Notch1 in oligodendrocyte (OL) development and differentiation. Early development of OPCs appeared normal in the spinal cord. However, at embryonic day 17.5, premature OL differentiation was observed and ectopic immature OLs were present in the gray matter. At birth, OL apoptosis was strongly increased in Notch1 mutant animals. Premature OL differentiation was also observed in the cerebrum, indicating that Notch1 is required for the correct spatial and temporal regulation of OL differentiation in various regions of the central nervous system. These findings establish a widespread function of Notch1 in the late steps of mammalian OPC development in vivo.

Visuo-motor and cognitive procedural learning in children with basal ganglia pathology.

We investigated procedural learning in 18 children with basal ganglia (BG) lesions or dysfunctions of various aetiologies, using a visuo-motor learning test, the Serial Reaction Time (SRT) task, and a cognitive learning test, the Probabilistic Classification Learning (PCL) task. We compared patients with early (<1 year old, n=9), later onset (>6 years old, n=7) or progressive disorder (idiopathic dystonia, n=2). All patients showed deficits in both visuo-motor and cognitive domains, except those with idiopathic dystonia, who displayed preserved classification learning skills. Impairments seem to be independent from the age of onset of pathology. As far as we know, this study is the first to investigate motor and cognitive procedural learning in children with BG damage. Procedural impairments were documented whatever the aetiology of the BG damage/dysfunction and time of pathology onset, thus supporting the claim of very early skill learning development and lack of plasticity in case of damage.
