Proposição de algoritmo para avaliação da qualidade acústica em ambiente escolar / Proposition of algorithm for evaluation of acoustic quality in school enrironment

Reginaldo Costa 11 June 2008 (has links)
Este trabalho estuda as relações existentes entre a qualidade acústica dentro de um ambiente construído - salas de aula da rede pública estadual - o desempenho escolar alcançado pelos alunos, a qualidade de vida do professor neste ambiente de trabalho e a percepção por parte da sociedade sobre os problemas causados pelo excesso de ruído. Trata-se mais especificamente da proposição de um algoritmo que possibilite ao administrador escolar verificar a qualidade acústica das salas de aula e de elaborar um plano de trabalho que vise sanar os problemas detectados. A sala de aula é um ambiente que merece uma atenção especial no quesito acústica. Neste espaço, a transmissão do conhecimento se realiza, em sua maioria, através da fala e num ambiente comprometido acusticamente o resultado final é diretamente influenciado pela sua qualidade. Salas de aula com baixa qualidade acústica geram prejuízos aos alunos em relação ao processo de ensino-aprendizagem e ao professor no que se refere a sua saúde vocal. Através da aplicação do algoritmo, o administrador escolar envolve toda a comunidade escolar na busca de dados que possibilite uma análise detalhada da situação da escola. Este envolvimento coletivo possibilita que as ações elaboradas e implementadas sejam mais facilmente acatadas por todos, pois os envolvidos apresentam-se representados no processo de coleta de dados e tomada de decisões. / This work studies the relationships found among these elements: the acoustic quality of a building - classrooms in public schools, the students performance, the teachers life quality, the perception from society on the problems caused by the noise excess. It deals more specifically with the proposition of an algorithm that makes possible the school administrator verify the acoustic quality of the classrooms and elaborate a work plan that intended to solve the detected problems. The classroom is a place that deserves special attention in the acoustics conditions. In this space the exchange of knowledge takes place in its majority through the speech and in an atmosphere acoustically disturbed, the final result is influenced directly by its quality. Classrooms with low acoustic quality generate damages to the students teaching-learning process and to the teachers vocal health. Through the application of the algorithm the school administrator involves the whole school community in the search of data that makes possible a detailed analysis of the situation of the school. This collective involvement makes actions more easily accepted by all, because all the people involved are represented in the process of data collection and in the decisions taken.

The expression of frustration by the child with attention deficit hyperactivity disorder within the classroom setting : a social work study

De Jager, Claire Helen 09 February 2005 (has links)
The researcher aimed in this study to answer the research question: how is frustration expressed by the child with attention deficit hyperactivity disorder (ADHD) in middle childhood within the classroom setting? The goal of the study was therefore to explore the expression of frustration in the child with ADHD in middle childhood within the classroom setting. The research population consisted of all children in middle childhood years who had been diagnosed with ADHD and were attending either Arthur Matthews or Montrose Primary Schools. The sampling method was purposive as subjects with these specific attributes were utilized. The extent of the investigation was limited to the observations of 20 children. The exploratory design was used in order to complete the empirical study. A checklist was used for the purpose of gathering data. This data was quantitative information on frustration expressed by children with ADHD in middle childhood, as observed by the researcher. Research results indicate that frustration plays a large role in the school life of a child diagnosed with ADHD. The findings also show that the child with ADHD directs much of his/her frustration towards him/herself. The research findings indicate that frustration that is not dealt with at an early stage will develop into aggression. In order to assist a child in dealing with his/her frustration, it is recommended that the child be taught coping mechanisms which assist him/her in ventilating frustration in a socially acceptable way. Further research into the effective implementation of teaching coping mechanisms to children in middle childhood with ADHD within the classroom setting is recommended. / Dissertation (MSD (Play Therapy))--University of Pretoria, 2004. / Social Work and Criminology / unrestricted

Om det inte är dyskalkyli - vad är det då? : En multimetodstudie av eleven i matematikproblem ur ett longitudinellt perspektiv

Sjöberg, Gunnar January 2006 (has links)
<p>One of the big problems of the Swedish nine-year compulsory school is the large number of pupils who fail to achieve a satisfactory standard in mathematics.

Belewenis van moeders van ATHV-leerders

Van Wyk, Margaretha Elizabeth 30 June 2004 (has links)
The aim of this study was to investigate the experiences of mothers of primary school learners diagnosed with attention deficit hyperactivity disorder (ADHD). The main determinant of parenting stress was contained in the primary symptoms of ADHD, namely, attention deficit, hyperactivity and impulsive behaviour, as well as in the disruptive effects on others in the immediate environment. The three primary symptoms of ADHD as listed above, often result in such secondary problems as learning deficiencies, poor self-image and inadequate social relations. Seven mothers of learners with ADHD were selected to participate in the empirical investigation. A qualitative research model was employed with specific use of a list of questions, participatory perception and unstructured interviews. Results obtained from the empirical research indicated that the symptoms of ADHD as manifested by the learners, as well as the accompanying secondary problems, impacted negatively on the mothers of these learners. / Educational Studies / M.

Music as an intervention strategy to address reading difficulties of grade 2 learners

Horn, Catharina Aletta 11 1900 (has links)
Reading is one of the most important skills (although a complex cognitive activity) a learner has to master during the early years of schooling. The reading process involves elements of a learner’s psychological, physical, linguistic, cognitive, emotional and social worlds. Despite the fact that all learners have to be able to read, there is an increasing awareness among professionals of the developmental and educational implications of reading difficulties with school-going learners world wide. Reading is a critical tool for the mastery of all other subjects a learner will meet and one of the best predictors of long-term learning achievement. Therefore, the need for support must be considered a priority area. After a thorough investigation and literary study, it is evident that the effective identification of learning difficulties needs a thorough understanding. Educators must realise that a given learner, who responds favourably to one instructional system, may respond very unfavourably to another, because learners are all unique individuals. To be able to combine speech sounds in a way that recipients can understand the message, learners have to be ready to develop an understanding of phonology, morphology and syntax, therefore maturation must always precede learning and, in the context of this study, emergent literacy must precede reading. Maturation is characterised by a fixed order of progression wherein the pace may vary, but not the sequence. The creative use of language is entirely dependent on the ability to assemble simple building blocks of sound into the complex structure we call sentences.It is widely accepted that music may be used to promote language development and the most crucial aspect in both music and language development is the perception of sound and the core in music and language are the ability to listen. The aim of this study was to investigate the use of music and related activities as part of an intervention strategy to improve reading skills, such as phonics, of learners who have reading difficulties. The researcher proved that a wellplanned intervention method and learning strategy through music activities may be used to develop the reading skills in learners who have reading difficulties. / Educational Studies / D.

The teaching of second level calculus at South African technikons : a didactical analysis of specific learning problems

Smith, Julien Clifford 11 1900 (has links)
This study was prompted by serious problems regarding specific teaching and learning problems in calculus at the technikon. The general aims were to identify and analyze particular teaching and learning problems relating to 2nd level engineering courses in calculus and to recommend improvements which could increase student performance in engineering calculus courses. An extensive study revealed world wide concern in calculus reform. The empirical research instruments consisted of structured questionnaires given to staff and students from nine technikons plus interviews. Five serious problem areas were identified: student ability in mathematics, content difficulty, background difficulties, timetable pressures and lecturer's presentation. The impact of training technology on calculus was investigated. Recommendations were that routine exercises can be done on computer with extra tutorial time for computer laboratory projects. Background recommendations suggested that schools give more time to trigonometry and coordinate geometry and that bridging courses at technikons for weaker students be developed. / Curriculum and Instructional Studies / M.

Some didactic implications of the admission of black pupils to the Indian primary schools in Phoenix with special reference to language proficiency

Chetty, Balaraj Vengetsamy 11 1900 (has links)
The influx of Black pupils seeking admission to Indian schools began in 1990 after the Democratic Movement's "all schools for all people" campaign was announced. The medium of instruction in Indian schools is English which is also the mother tongue. Therefore Black pupils who come on transfer from schools in the KwaZulu township are immediately faced with a language problem as they are taught in the mother tongue untii standard three, when they switch to English. This research project arose as a result of the researcher's experience with Black pupils, whom he - felt were severely linguistically underprepared for academic study in the senior primary phase. Furthermore, most present day teachers were trained for monocultural schools and have little or no experience of multicultural education. The main problem that this research focuses on includes the learning problems encountered by Black pupils in Indian primary schools and the concomitant teaching problems their teachers experience. / Educational Studies / M.

Bidirectional Helmholtz Machines

Shabanian, Samira 09 1900 (has links)
L'entraînement sans surveillance efficace et inférence dans les modèles génératifs profonds reste un problème difficile. Une approche assez simple, la machine de Helmholtz, consiste à entraîner du haut vers le bas un modèle génératif dirigé qui sera utilisé plus tard pour l'inférence approximative. Des résultats récents suggèrent que de meilleurs modèles génératifs peuvent être obtenus par de meilleures procédures d'inférence approximatives. Au lieu d'améliorer la procédure d'inférence, nous proposons ici un nouveau modèle, la machine de Helmholtz bidirectionnelle, qui garantit qu'on peut calculer efficacement les distributions de haut-vers-bas et de bas-vers-haut. Nous y parvenons en interprétant à les modèles haut-vers-bas et bas-vers-haut en tant que distributions d'inférence approximative, puis ensuite en définissant la distribution du modèle comme étant la moyenne géométrique de ces deux distributions. Nous dérivons une borne inférieure pour la vraisemblance de ce modèle, et nous démontrons que l'optimisation de cette borne se comporte en régulisateur. Ce régularisateur sera tel que la distance de Bhattacharyya sera minisée entre les distributions approximatives haut-vers-bas et bas-vers-haut. Cette approche produit des résultats de pointe en terme de modèles génératifs qui favorisent les réseaux significativement plus profonds. Elle permet aussi une inférence approximative amérliorée par plusieurs ordres de grandeur. De plus, nous introduisons un modèle génératif profond basé sur les modèles BiHM pour l'entraînement semi-supervisé. / Efficient unsupervised training and inference in deep generative models remains a challenging problem. One basic approach, called Helmholtz machine, involves training a top-down directed generative model together with a bottom-up auxiliary model used for approximate inference. Recent results indicate that better generative models can be obtained with better approximate inference procedures. Instead of improving the inference procedure, we here propose a new model, the bidirectional Helmholtz machine, which guarantees that the top-down and bottom-up distributions can efficiently invert each other. We achieve this by interpreting both the top-down and the bottom-up directed models as approximate inference distributions and by defining the model distribution to be the geometric mean of these two. We present a lower-bound for the likelihood of this model and we show that optimizing this bound regularizes the model so that the Bhattacharyya distance between the bottom-up and top-down approximate distributions is minimized. This approach results in state of the art generative models which prefer significantly deeper architectures while it allows for orders of magnitude more efficient approximate inference. Moreover, we introduce a deep generative model for semi-supervised learning problems based on BiHM models.

Entrepreneurskaponderrig vir leerders met leerprobleme / Abraham Stefhanus van der Merwe

Van der Merwe, Abraham Stephanus January 1999 (has links)
This research investigates the education of entrepreneurship to learners with learning difficulties. It is important to keep in mind the rights and possibilities of a learner with learning difficulties. Two entrepreneurship programmes were presented to two different groups of learners at Oom Paul School. Learners with learning disabilities can be categorised as poor performers, learners with behavioural and emotional problems, development problems (for example a language deficit), as well as learners with permanent disabilities- physically, intellectual and sensorial. An important part of this research will focus on the discussion on the causes of learning difficulties and problems of learners. One of the most important aims in education, especially in teaching learners with learning difficulties, is to guide learners to become a part of adulthood and the business world as a responsible and active member of society. Unfortunately, there are many learners who- after a successful school career seems to get "lost" along the way, because of society's discrimination. Several entrepreneurial programmes have been developed and have been implemented with great success at various schools, with reference in particular to the programmes "Business Ventures" and "Entrepreneurskap: jou eie besigheid". Above mentioned programmes are developed for main stream education and are not necessarily suitable for learners with learning difficulties. According to literary studies on education on entrepreneurship, this study field is relatively new in RSA and that no research regarding entrepreneurship education for learners with learning difficulties has been done. This research has pointed out that the teaching and education of entrepreneurship to learners with learning difficulties can be successful with a few adjustments. The new outcomes-based curriculum for general education and training for further education is Curriculum 2005. This curriculum is learner centred and is beneficiary for the learner with disabilities and difficulties. The principles of outcomes-based curriculum (Curriculum 2005) contribute to the accommodation of all learners in their diversity and needs. The society is looking forward to the implementation of this new curriculum, due to the fact that discrimination against learners with learning disabilities/difficulties will no longer be part of our education. Awareness of entrepreneurship and teaching of entrepreneurship is part of the eight learning areas and also one of the critical outcomes of Curriculum 2005. Entrepreneurial awareness can offer a meaningful contribution to solve an essential problem in the RSA. / Thesis (M.Ed.)--Potchefstroom University for Christian Higher Education, 2000
