Afrikaans text / Die studie ondersoek die leemte aan teoreties gefundeerde riglyne om pleegouers in die bekendmakingsproses van hulle kind se MIV-positiewe status te ondersteun Die studie geskied binne die teoretiese raamwerk van ʼn intervensienavorsingsmodel. In die empiriese navorsing is die vrese en probleme van pleegouers by die bekendmakingsproses ondersoek. Daar is bevind dat hierdie vrese en probleme in ag geneem moet word in die beoogde riglyne. Die kognitiewe ontwikkeling van die kind is deur middel van ʼn literatuurstudie ondersoek om vas te stel watter kennis, denke en inligting die kind op verskillende ouderdomme begryp. Daar is bevind dat kinders wat MIV-positief is, moontlike agterstande ondervind en dat die riglyne gevolglik gebaseer moet word op die toenemende ontwikkeling van die kind, met begrip vir individuele ontwikkelingsverskille. Voorts is bevind dat pleegouers se eie gereedheid ʼn belangrike rol speel. Alhoewel die pleegouer die bekendmakingsproses self moet aanvoer en hanteer is dit belangrik dat die pleegouers deur ʼn interdissiplinêre span ondersteun en begelei sal word. / This study investigates the absence of theoretical grounded guidelines to support foster parents when disclosing paediatric HIV. The study was done within the theoretical framework of an intervention research model. The empirical research investigated the fears and problems experienced by foster parents during the disclosure process. It was found that these fears and problems should be taken into account when compiling guidelines. The child‟s cognitive development was researched by way of a literary study in order to determine what knowledge, thoughts and information the child is able to grasp at different ages. It was found that children who are HIV positive could possibly lag behind and that the guidelines should therefore be based on the accumulative development of the child, with consideration given to individual developmental differences. Furthermore, it was established that foster parents‟ own readiness plays an important role. For this reason the foster parents should be supported and guided by an interdisciplinary team, but that they themselves should take care and execute the process of disclosure. / Social Work / M.

The social and economic environments in which children develop are regarded as important variables which relate to academic performance. In order to support learners in achieving academically, an understanding of the role of these different variables is essential. The aim of the study was to investigate the influence of additional educational support on the resilient behaviour and subsequent academic performance of adolescents in Grades 9 and 10. A sample of 117 high school adolescents was used. Schools that offer additional educational support tend, on average, to show a healthier teacher-learner relationship, more parental involvement, superior cognitive development and better study orientation. All these factors were also found to contribute to a learner’s potential to demonstrate resilient behaviour. Based on the literature study and the empirical investigation, recommendations to parents, teachers and schools have been made. / Psychology of Education / M. Ed. (Guidance and Counselling)

A literature and an empirical study were undertaken to investigate home factors affecting the academic performance of a group of learners in three primary schools in the Brits district. From the literature it became evident that the early years of an individual's life are critical for development, especially cognitive development. Parents, as a child's primary educators have an important role to play in their child's cognitive development. By establishing a challenging and stimulating environment in which the child is exposed to a variety of experiences, the parents can enhance their child's cognitive development and by implication his/her later academic performance. Various other factors such as parental involvement, expectations, parenting style and home background were found to affect a child's academic performance. In the empirical study a group of academic achievers and underachievers were compared with regards to early cognitive stimulation received, degree of parental involvement and the quality of their homes. / Psychology of Education / M.Ed.

The phenomenon of social isolation among school children in most instances goes unnoticed by both teachers and parents and this oversight could have serious negative restraints on the socially isolated child's cognitive, affective, moral, personality and social development. Social isolation can be caused either through being rejected or neglected by the peer group. This study was carried out among primary and secondary school learners to detei:,mine the extent to which these children are socially isolated; and to identify factors contributing to learners' social isolation. The aim of the study is to provide teachers and parents with a foundation and rationale for effective intervention. A literature study was done to identify the factors influencing social isolation. Some of the factors identified were: social competence, self-esteem, psychological well-being, intelligence, academic achievement, moral values, physical disability, sports participation, self-perceived physical attractiveness, self-perceived physical disability, marital status of parents, parental supervision, parental acceptance, parental autonomy granting and parental conflict. All aspects of development (namely, physical, cognitive, affective, personality, moral and social) were studied in relation to the phenomenon of social isolation. By means of an empirical investigation, it was found after a regression analysis that self-esteem, obedience and social competence accounted for most of the variance in social isolation for primary school learners and in the case of secondary school learners, social competence, family supervision and self-esteem. The two most common factors were social competence and selfesteem. From the empirical findings it was also noted that learners' home language and grade were also associated with social isolation. The educational implications of the findings of the literature and the empirical study are discussed and guidelines given to assist teachers and parents to identify and eliminate the factors contributing to the development of isolation among school learners. If both parents and teachers take cognisance of these recommendations and try to implement them, it should help children in their self-actualisation and facilitate their attainment of adulthood with the least developmental restraints. / Psychology of Education / D.

Text in Afrikaans / It has been said that pupils are not adequately trained to think independently in the current educational system of South Africa. Therefore this research has been undertaken from a psycho-educational perspective to assess the contribution which a programme in cognitive empowerment can make towards the cognitive development and especially the general psychological development of teaching students in their final study year as potential career entrants. From this viewpoint recommendations can be made re the use of this programme in the broader educational context. In this study research has been done from a psycho-educational perspective concerning the cognitive, affective, normative and conative development of the late adolescent and the early career entrant and his/her personality in terms of this career. A group of final year teaching students, who were potential career entrants completed the Programme in Cognitive Empowerment. Before and after the presentation of this programme different media of evaluation were put into use. Based on this research, deductions have been made concerning the contribution which training in the programme has made to the development of the novice teachers. Finally, recommendations have been made concerning the implementing of such a programme. / Daar word beweer dat die onderwysstelsel in Suid-Afrika leerlinge nie toereikend tot selfstandige denke begelei nie.

Text in English / The literature review indicated similarities between education and chess playing and possible transfer of knowledge between these two different domains. A link was then suggested between some aspects of intellectual abilities and chess instruction in children, but not in adults (Frydman & Lynn, 1992; Waters, Doll & Mayr, 1987). In this research study the aim was to explore the relationship between chess playing and cognitive and intellectual development in Grade R learners at Garsieland. Therefore the positive influence that chess playing brings to bear on the intelligence of 64 Grade R learners (as measured on intelligence scales) was investigated. The data was collected through short biographical questionnaires and psychometric tests and the participants in both groups were assessed on two occasions. The study suggested that chess instruction exerted a positive (small) effect on Performance intelligence and subsequently on the Global scale of the Junior South African Intelligence Scales. The children in both groups also exhibited improved cognitive development after the 40 week period during 2009. / Psychology / M.A. (Psychology)

A Sociedade e o mercado de trabalho exigem de cidadãos e trabalhadores, nos últimos tempos, um perfil de desempenho diferente daquele até então aceito. As principais carências do trabalhador dizem respeito, dentre outras necessidades, ao desempenho de certas competências pessoais e a melhoria do funcionamento cognitivo. As escolas, responsáveis pela preparação dessas pessoas para viver em Sociedade - o que inclui a preparação para o mundo do trabalho - não costumam realizar ações educacionais intencionais na direção da melhoria do desenvolvimento cognitivo de seus alunos. O foco do presente estudo está na possibilidade da Escola realizar intencionalmente o desenvolvimento cognitivo de estudantes, futuros trabalhadores. utilizando um programa já existente, criado e estruturado para essa finalidade por Reuven Feuerstein. No final da década de 1940, coube a Feuerstein a tarefa de educar centenas de crianças e jovens, órfãos da guerra, para que se tornassem cidadãos autônomos e produtivos. Diante da necessidade real de modificar o desempenho cognitivo e resgatar a cidadania dessas pessoas, Feuerstein criou - a partir de sua visão de mundo, de um conjunto de crenças por ele estabelecido e de sua experiência - duas teorias: Modificabilidade Cognitiva Estrutural e Experiência de Aprendizagem Mediada e três sistemas inter-relacionados, ou seja, um sistema de avaliação: Avaliação Dinâmica do Potencial de Aprendizagem, um sistema de intervenção: Programa de Enriquecimento Instrumental e um sistema de manutenção: Modelagem de Ambientes Modificadores. Avaliar o efeito do primeiro nível do Programa de Enriquecimento Instrumental (PEI I) no desenvolvimento cognitivo de estudantes da 3ª série de Escolas pública ou privada de Ensino Médio é o objetivo amplo desse trabalho. Em resumo, foram envolvidos no projeto 96 estudantes (54 rapazes e 42 moças) de duas Escolas de Ensino Médio: uma privada e outra pública. Sessenta e sete desses alunos participaram dos grupos experimentais que se submeteram ao PEI I e as outras 29 pessoas integraram grupos de controle, não participando, portanto, da aplicação do Programa. Todos os estudantes participaram de uma avaliação inicial diante de seis instrumentos, sendo que alguns deles permitiam avaliação dinâmica. Da análise dos resultados dos instrumentos, que envolviam avaliação dinâmica, foram levantadas necessidades e estabelecidos procedimentos de intervenção. Os alunos dos grupos experimentais foram submetidos ao primeiro nível do Programa de Enriquecimento Instrumental (PEI I). Durante a aplicação do PEI I, alunos participaram de avaliação intermediária, realizada a partir da aplicação de instrumento de avaliação e ou de questionário para levantamento da percepção dos estudantes sobre o PEI. Finalmente, todos os participantes foram submetidos a uma avaliação final. Os resultados foram analisados de forma descritiva e estatística. Os testes U ou de Mann- Whitney e o teste t de Student foram utilizados para indicar semelhanças e diferenças prováveis entre os desempenhos dos grupos de alunos. A partir da discussão desses resultados foram montadas proposições que justificaram as seguintes conclusões: A modificabilidade cognitiva estrutural dos estudantes dos grupos experimentais foi ampliada. O desenvolvimento cognitivo demonstrado pelos estudantes dos grupos experimentais foi maior que o desempenho cognitivo demonstrado pelos alunos do grupo de controle. / In the recent past, both society and labour market are demanding from citizens a performance far different from those accept until then. The major lacks of workers may concern, among others, to the development of specific personal competences and to the improve of the cognitive process. Schools, responsible for the preparation for life in society - including the life in the labour market - don\'t usually take intentional educational actions aiming the improve of the cognitive development of their students. The focus of the present study is mainly on analyzing the possibility of Schools to make an intentional effort to develop student\'s cognitive habilities, future workers, using a preexisting program created and structured for this meaning by Reuven Feuerstein. In the late 40\'s, Feurstein took the task of teaching hundreds of children and teenagers, war orphan children, to become autonomous and productive citizens. Facing the real need of improving their cognitive habilities and rescuing their citizenship, Feuerstein came up - using his own wide world perception, personal beliefs and experience - with two theories: Structural Cognitive Modifiability (SCM) and Mediated Learning Experience (MLE) and three interrelated systems, or an evaluation system: Learning Potential Assesment Device (LPAD), an interventional system: Feuerstein Instrumental Enrichment (FIE) and a maintenance system: Shaping Modifying Environments (ME). The aim of this paper is to evaluate the effect of the first level of the Feuerstein Instrumental Enrichment (FIE I) on 3rd grade public or private High School student\'s cognitive development. Summing up, there were 96 students involved in this project (54 boys and 42 girls) from two different High Schools: one private and one public. Sixty seven of these students were placed on experimental groups that were submitted to FIE I and the other 29 kids took part on control groups, staying away from the program application. All the students participated on an initial evaluation, facing six instruments, some of then allowing a dynamic evaluation. From the instrument result analysys, needs were raised and intervention procedures were established. The students\'s experimental group was submitted to the first level of the Feuerstein Instrumental Enrichment (FIE I). During its application, the students had an intermediary evaluation, made by the application of the evaluation instrument and by a questionnaire to measure the student\'s level of perception about the (FIE I). Finally, all the participants were submitted to a final evaluation. The results were analyzed in a descriptive statistical way. The U or Mann-Whitney tests and the t for Student test were used to indicate probable similarities and differences among the student\'s groups performances. From its discussion were put together propositions to justify the following conclusions: The student\'s experimental group structural cognitive modifiability was raised. The cognitive development shown by the student\'s experimental group was higher than the cognitive performance shown by the student\'s control group.

The deaf child’s primary handicap is his inability to hear human speech. The whole functioning of the deaf child is hampered by his hearing loss. This implicates that deafness can cause secondary problems such as: -- language problems; -- speech problems; -- thinking problems; -- social problems; -- emotional problems; -- educational problems; -- occupational problems; and -- family problems. These problems impose a special challenge to people who intervene with deaf children. The deaf child cannot communicate intelligibly. The therapist has to pay special attention to this problem and to the way in which communication will commence and continue. Pedotherapeutic intervention implicates effective communication. The use of language plays an important role in the Educational-psychological practice. Diagnostic tests and therapeutic techniques require an average language capability. The therapist must seek alternative concrete ways in which to assess the deaf child and to solve the child’s problems. The creation of a work of art is a concrete sensory act. A variety of authors state that, most children can project their deepest inner feelings through a work of art without fear and pain. The instructions given for art therapy are simple and most children feel safe to create. A child’s work of art has diagnostic as well as therapeutic value. It is important that the therapist will recognize and interpret the projected symbols and that he will use it to change and expand the deaf child’s world of meaning. During the assessment of a child’s drawing the therapist must take aspects of the art work, such as colour, form, line, art material, the content of the drawing, the perceptual and motor development of the child, the child’s age, non-verbal communication and verbal communication during the creative process, into consideration. The therapist must not use above-mentioned directions at random. Every individual’s work of art must be assessed in a phenomenological way, before any conclusions can be made. A private, well equipped art therapy room is necessary for the child in order to feel safe to explore and create. The therapist who intervenes with deaf children has to be well trained. He must have knowledge and experience of deafness, know sign language and should have exceptional language abilities. In this study the therapist applied art therapy with a deaf child. Both the child and his educators were involved in therapy. The therapy was successful. Most of the therapeutic goals were achieved. The therapist needed to adapt the way of communication in order to enhance the level of communication between her and the deaf child. Art therapy can be successfully used with the deaf child because adequate communication is possible, the deaf child can identify with the therapeutic content and transcendence is possible. Some deaf children do not respond well to art therapy. The uniqueness of each deaf child should be taken into consideration before a therapeutic technique can be chosen. / Dissertation (MEd (Educational Psychology))--University of Pretoria, 2006. / Orthopaedic Surgery / unrestricted
