Objetivo. Avaliar a função aritmética em crianças com Transtorno do Déficit de Atenção / Hiperatividade (TDAH) e determinar se o tratamento com psicoestimulante afeta seu desempenho (braço clínico), além de verificar o padrão de ativação neural em um subgrupo desta amostra durante tarefas de cálculos aritméticos (braço neuroimagem). Métodos. Quarenta e duas crianças (de 9 a 12 anos) participaram do braço clínico: 20 com TDAH segundo os critérios do DSM-IV e 22 controles. Estas crianças foram classificados com ou sem dificuldades aritméticas com base em seu desempenho em três testes aritméticos utilizados no Brasil. Todos os participantes do braço clínico foram avaliados em dois momentos: tempo 1 e no tempo 2 quando as crianças com TDAH estavam em uso de metilfenidato (MTF) a uma dose de 0,3-0,5 mg/kg. Foi avaliado o desempenho global em aritmética e, especificamente, exploramos a subtração nos dois tempos. Foram também estudadas 10 crianças com TDAH (seis das quais participaram do braço clínico) que participaram com uso de metilfenidato e 10 crianças saudáveis (oito das quais participaram do braço clínico) que realizaram exame de ressonância magnética funcional (RMf) em duas tarefas (cálculos exatos e aproximados ) utilizando paradigma com desenho em bloco em aparelho de 3.0 Teslas. Resultados. O grupo TDAH, quando não medicado (tempo 1) cometeu mais erros aritméticos que os controles (p < 0,001). No entanto, quando em uso de MTF, o grupo TDAH (tempo 2) fez significativamente menos erros quando comparado com a sua linha de base (tempo 1) e quando comparados aos seus controles (tempo 2). Em exercícios de subtração que requerem procedimentos de empréstimos (subtração complexo), o grupo de TDAH (tempo 1) cometeu mais erros do que nos controles, melhorando significativamente quando em uso da medicação (p = 0,039). Em relação à RMf não houve diferenças específicas entre os grupos em cada tarefa isoladamente. Entretanto, houve interação entre o tipo de cálculo (aproximado vs. exato) e grupo (controle vs. TDAH): as crianças com TDAH mostraram atividade diferente do grupo controle na região do cíngulo posterior e pré-cúneo, considerando as duas formas de cálculo. Conclusões. O uso de vários testes aritméticos validados permite uma avaliação abrangente e eficaz de crianças em risco de dificuldades de aprendizagem. Assim, fomos capazes de mostrar que o nosso grupo de crianças com TDAH tinha dificuldades aritméticas significativas, mas o tratamento com MTF trouxe melhoras substanciais. A melhora observada foi no desempenho geral e, especificamente, para o desempenho em subtração complexa. Esta melhora pode ter sido devido ao aumento de habilidades de memória de trabalho, gerando menos erros involuntários. Em relação aos resultados de RMf mostramos um resultado ainda não descrito na literatura: a alteração na região posterior do giro do cíngulo e pré-cúneo que possivelmente se deve a alteração funcional intrínseca do TDAH na vigência de medicação com metilfenidato, uma área que já foi descrita na literatura sobre TDAH porém não nessa condição / Objective. To evaluate arithmetic function in children with Attention Deficit Hyperactivity Disorder (ADHD) and to determine whether stimulant treatment affects their performance (clinical arm), besides verifying the patterns of neural activation on a subgroup from this sample during trials testing arithmetical calculation (neuroimaging arm). Methods. Forty-two kids (from 9 to 12 years old) took part in the clinical arm: 20 with ADHD diagnosed according DSM-IV criteria and 22 from control group. These children were classified with or without arithmetic difficulties based on their performance on three arithmetic tests used in Brazil. All participants from the clinical arm were evaluated at 2 time points: time 1 and time 2 when ADHD children were on methylphenidate (MPH) at a dose of 0,3/0,5 mg/kg. Global performance in arithmetic, and specifically, subtraction in these two times was explored. We also evaluate 10 ADHD children (6 of these from the clinical arm) on MPH and 10 healthy control children (8 of these from the clinical arm) using fMRI (Functional Magnetic Resonance Imaging) during two trials testing approximate and exact arithmetical calculation using a block design paradigm in a 3.0 Teslas device. Results. The ADHD group, when unmedicated (time 1) made more arithmetic errors than controls (p < 0,001). However, when on MPH, ADHD group (time 2) made significantly fewer errors when compared to their baseline (time 1) and when compared to their controls (time 2). On subtraction exercises that require borrowing procedures (complex subtraction), the ADHD group (time 1) committed more errors than controls, while significantly improvement in the medicated state (p = 0,039). Regarding the fMRI there was no specific difference between groups on each task isolated. However, there was an interaction between the type of calculation (approximate vs. exact) and group (control vs. ADHD): children with ADHD showed different activity from the control group in the posterior cingulate and precuneus, considering both forms of calculation. Conclusions. The use of multiple validated arithmetic tests enables a comprehensive and effective assessment of children at a risk for learning difficulties. Thus, the study was able to show that the ADHD group had significant arithmetic difficulties; on the other side MPH treatment brought substantial improvement. This mentioned improvement was observed in general development, and specifically on complex subtraction performance, what could have been caused by the increase of working memory skills, generating less involuntary errors. Regarding the fMRI, it brought up results not yet described by literature: the alterations of the posterior cingulate gyrus and precuneus what is possibly due to the intrinsic functional alteration of ADHD on MPH, an area that has already been described by ADHD literature nevertheless not on under this condition

In Namibia today few learners with behavioural and learning problems are within special schools as most are placed within the mainstream school system. Placing these learners within the mainstream system is part of the policy of Inclusive Education (IE) because it argues that this would benefit these learners and also save resources. IE is concerned with addressing barriers to learning and behavioural problems are regarded as one of these barriers. IE argues for a series of new approaches to the diagnosis and response to learners with behavioural problems. This poses challenges for teachers in mainstream schools. Teachers are at the forefront of this situation as they are usually the first to observe and experience the behavioural problems in the schools and are expected to respond appropriately. They find this situation both challenging and problematic. This research explores a sample of teachers’ perceptions of learners’ behavioural problems. To collect in-depth information, this study followed a qualitative approach with a case study design. The data were collected through semi-structured interviews, supplemented with observation and document analysis. The study consisted of fifteen respondents: three principals, three teacher counsellors and nine teachers from the three selected schools. This study illuminates the types of behaviour that teachers encounter, the impact of these behaviours, the factors seen as contributing to these behaviours, and how teachers and the school system deal with these behaviours. In addition the study applies Bronfenbrenner’s bioecological model (1992) to explain how the behaviours manifested by Grade 11 and 12 learners, and identified as problematic by teachers, are part of an interconnected nested social system. The results from the study indicate the manifestation of behavioural problems to be common occurrences in secondary schools are evident, amongst others, through fighting, bullying, substance abuse, truancy, and disrespect of teachers and authority. The teachers pointed to the prevalence of these problems as well as the serious impact such problems have on these learners, their fellow learners, and on the teachers. The teachers identified a complex array of what they saw as contributing factors located within the school, peer groups, family and home circumstances, the local community, as well within the national education policy, the economy and society. The study points to some specific, as well as broader, lessons and opportunities for action both for those managing the education system at the national level and for schools and teachers.

The research reported herein examined the emotional and behavioral characteristics of adolescent Hispanic students with and without learning disabilities from a middle school in north central Texas. The data were based on all students enrolled at the campus (N = 986), but focused on 55 students of Hispanic descent with learning disabilities and 55 students without. The data accrued for this study utilized a school discipline database. In addition, a 43-item behavioral rating scale was completed on each student of the more focused group. Methods of data analysis were derived from descriptive statistics, one-way analysis of variance, and multiple regression measurements. The results indicate that Hispanic students with learning disabilities often exhibit more disruptive behaviors.

Implementation of evidence-based practices in Texas schools was examined through a survey disseminated through 495 special education directors in 20 state educational service centers. The district-level directors were asked to forward the survey to all personnel providing direct or indirect services to students with EBD. Survey participants were asked to rate 27 evidence-based interventions for students with EBD in three categories on a 5-point Likert scale: (a) importance of the intervention; (b) frequency of use of the intervention; and (c) preparedness to implement the intervention. With a response rate of 32% and representation from all 20 educational service center areas, data were analyzed through simple frequency statistics to determine that most respondents were public school special educators who had been in their current position for 5 years or less. They identified a climate that supports successful teaching and learning and clear rules/expectations as very important. They reported using procedures for the use of physical restraint most frequently, and being most well-prepared to implement clear rules/expectations. A canonical correlation analysis revealed an inverse relationship between importance ratings of tertiary level interventions and frequency of use and preparedness to implement primary level interventions which implies that while practitioners rate tertiary level interventions as important, they are more likely to be well-prepared to implement primary level interventions and to do so with more frequency. Additionally, a review of literature is provided and results and analysis of the survey are discussed as well as recommendations for the future.

Title: Evaluation of the motoric docility level of adolescents with specific learning and behavior disorders. Author: Bc. Ladislav Kaňka Advisor: prof. Ing. Václav Bunc, CSc. Aim of the thesis: The aim of this study is to evaluate the motoric docility level of pupils with specific learning a behavior disorders through the Iowa-Brace test and to compare the results with data from pupils without these disorders. Method: Testing motoric abilities of 13-14 year old (adolescents) with specific learning a behavior disorders through the Iowa-Brace test and later comparing to pupils who do not have any specific learning and behavior disorders. The data was processed with the program IBM SPSS Statistics 24 and then evaluated. Results: Specific learning and behavior disorders have a significant negative impact on the motoric docility level of an individual, which has been proved by poorer performance of these pupils in a test studying the motoric docility level of probands (Iowa-Brace test). The difference in the overall performance in the Iowa-Brace test depends more on the specific learning and behavior disorders than on the sex of the individual. The biggest difference between pupils with and without specific learning and behavior disorders was noticed during the exercise "Turek" (this exercise assesses...

The purpose of this study was to examine any differences that may exist among demographic variables such as gender, age, and race in regard to internalization of society and media messages leading to body dissatisfaction that may lead to disordered eating behaviors such as preoccupation with weight, dieting, and eating restraint. A total of 324 participants completed the demographic questionnaire, the Multidimensional Body Self Relations Questionnaire, the Sociocultural Attitudes Towards Appearance Questionnaire for women, the Sociocultural Attitudes Towards Appearance Questionnaire-Revised-Male-Version for men, and Rotter’s Internal-External (I-E) Locus of Control Scale. The results of this study found, as predicted, that Caucasians reported higher internalization, higher body dissatisfaction, and higher preoccupation with weight, dieting, and eating restraint than African Americans. This study showed no differences regarding men’s and women’s internalization or body dissatisfaction but did reveal that women reported higher preoccupation with weight, dieting, and eating restraint than men. Regarding age, this study found that age did not predict internalization, body dissatisfaction, or preoccupation with weight, dieting, and eating restraint.
