Cette recherche propose d’étudier et de présenter des supports susceptibles d'améliorer le processus d'apprentissage des personnes malentendantes et sourdes par la médiation de nouveaux outils comme les tablettes tactiles. La question est de savoir si l’introduction de ces nouveaux outils, pourrait permettre la création de didacticiels adaptés aux spécificités cognitives des enfants sourds.Dans le contexte actuel, notre hypothèse est que les nouvelles technologies informatiques et les outils numériques (comme les tablettes tactiles) influenceraient positivement le processus d’apprentissage des élèves sourds et malentendants.En conséquence, nous avons créé un logiciel éducatif, Digisthésia, qui a été conçu et adapté aux besoins des élèves sourds et malentendants. Le but de cet outil était de développer et d’améliorer 4 des principales potentialités cognitives : l’attention, la mémoire, la vitesse de traitement et la résolution de problèmes.Notre protocole a mobilisé 80 élèves de 7 collèges de Lyon et de la périphérie lyonnaise : 40 élèves avec différents degrés de déficience auditive, des sujets implantés et appareillés (20 participants ont utilisé le logiciel éducatif Digisthésia / 20 personnes ont fait partie du groupe de contrôle) ainsi que 40 élèves sans déficiences auditives (20 participants qui ont utilisé notre logiciel éducatif sur tablette tactile / 20 élèves ont fait partie du groupe témoin). Les résultats indiquent que la médiation par les nouvelles technologies a renforcé les potentialités cognitives des élèves sourds et malentendants. Nous avons observé un progrès au niveau de l’apprentissage des participants sourds et malentendants suite à l’utilisation du logiciel éducatif Digisthésia sur tablette tactile. / This research proposes to study and present materials that can improve the learning process for people who are hard of hearing and deaf by leveraging the use of new tools such as touch tablets. The question is whether the introduction of these new tools could allow the creation of software tools that more adapted to the cognitive specificities of deaf children.In the current context, our hypothesis is that new computer-base technologies and digital tools (such as touch tablets) would positively influence the learning process for students who are deaf and hard of hearing.As a result, we have created the educational software Digisthésia that has been designed and adapted to the needs of students who are deaf and hard of hearing. The aim of this tool was to develop and improve 4 important cognitive parameters such as attention, memory, processing speed and problem solving.Our protocol mobilized 80 students from grade schools from and near Lyon: 40 students suffering from different degrees of hearing impairment, with an without cochlear implants (20 subjects used the tablet/20 subjects were part of the control group). As well as 40 students with no hearing impairments (20 subjects who used the educational software Digisthésia and the tablet /20 subjects who were part of the control group).The results indicate that leveraging the new technologies has enhanced the cognitive potential of deaf and hard of hearing students. We have seen progress in the learning of deaf and hard of hearing participants as a result of the use of tablets and our software.

Fetal Alcohol Syndrome (FAS) is a preventable cause of mental retardation and is the severest category within Fetal Alcohol Spectrum Disorder (FASD). As gestational alcohol exposure affects fetal cognitive functioning, children with FAS present with intellectual deficits. Unfortunately FASD prevalence rates are increasing amongst infants and school-going children. The main goal of this study was to compare the neurodevelopmental subscales of infants diagnosed with FAS, Partial FAS and non- FAS. Seventy-four infants with confirmed FAS, Partial FAS or Non- FAS diagnoses were assessed using the Griffiths Mental Developmental Scale. Development assessed at 7-12 and 17-29 months of age showed that, regardless of a FAS, PFAS or Non-FAS diagnosis, all infants performed weaker at their assessment at 17-29 months. The Subscales significantly affected included Personal-Social, Eye- Hand Coordination and Performance. The infants with FAS and PFAS displayed the most marked developmental delays. From this study it can be concluded that there are definite neurodevelopmental profiles for infant's diagnosed with FAS, PFAS and/or Non-FAS, highlighting the significant impact of prenatal alcohol exposure on various aspects of infant development. / Social work / M.Diac.

Cette recherche se caractérise, premièrement, par une discussion théorique sur le concept d'agent autonome, basée sur des éléments issus des paradigmes de l'Intelligence Artificielle Située et de l'Intelligence Artificielle Affective. Ensuite, cette thèse présente le problème de l'apprentissage de modèles du monde, en passant en revue la littérature concernant les travaux qui s'y rapportent. À partir de ces discussions, l'architecture CAES et le mécanisme CALM sont présentés. CAES (Coupled Agent-Environment System) constitue une architecture pour décrire des systèmes basés sur la dichotomie agent-environnement. Il définit l'agent et l'environnement comme deux systèmes partiellement ouverts, en couplage dynamique. L'agent, à son tour, est composé de deux sous-systèmes, l'esprit et le corps, suivant les principes de la situativité et de la motivation intrinsèque. CALM (Constructivist Anticipatory Learning Mechanism) est un mécanisme d'apprentissage fondé sur l'approche constructiviste de l'Intelligence Artificielle. Il permet à un agent situé de construire un modèle du monde dans des environnements partiellement observables et partiellement déterministes, sous la forme d'un processus de décision markovien partiellement observable et factorisé (FPOMDP). Le modèle du monde construit est ensuite utilisé pour que l'agent puisse définir une politique d'action visant à améliorer sa propre performance. / Esta pesquisa caracteriza-se, primeiramente, pela condução de uma discussão teórica sobre o conceito de agente autônomo, baseada em elementos provenientes dos paradigmas da Inteligência Artificial Situada e da Inteligência Artificial Afetiva. A seguir, a tese apresenta o problema da aprendizagem de modelos de mundo, fazendo uma revisão bibliográfica a respeito de trabalhos relacionados. A partir dessas discussões, a arquitetura CAES e o mecanismo CALM são apresentados. O CAES (Coupled Agent-Environment System) é uma arquitetura para a descrição de sistemas baseados na dicotomia agente-ambiente.

O CALM (Constructivist Anticipatory Learning Mechanism) é um mecanismo de aprendizagem fundamentado na abordagem construtivista da Inteligência Artificial. Ele permite que um agente situado possa construir um modelo de mundo em ambientes parcialmente observáveis e parcialmente determinísticos, na forma de um Processo de Decisão de Markov Parcialmente Observável e Fatorado (FPOMDP). O modelo de mundo construído é então utilizado para que o agente defina uma política de ações a fim de melhorar seu próprio desempenho. / This research is characterized, first, by a theoretical discussion on the concept of autonomous agent, based on elements taken from the Situated AI and the Affective AI paradigms. Secondly, this thesis presents the problem of learning world models, providing a bibliographic review regarding some related works. From these discussions, the CAES architecture and the CALM mechanism are presented. The CAES (Coupled Agent-Environment System) is an architecture for describing systems based on the agent-environment dichotomy. It defines the agent and the environment as two partially open systems, in dynamic coupling. The agent is composed of two sub-systems, mind and body, following the principles of situativity and intrinsic motivation. CALM (Constructivist Learning Anticipatory Mechanism) is based on the constructivist approach to Artificial Intelligence. It allows a situated agent to build a model of the world in environments partially deterministic and partially observable in the form of Partially Observable and Factored Markov Decision Process (FPOMDP). The model of the world is constructed and used for the agent to define a policy for action in order to improve its own performance.

Text in Afrikaans / No specific measuring instrument to determine the emotions of primary school Pupils exists. There is nevertheless a dire need for a reliable measuring instrument for this purpose. Initially a literature study was undertaken and emotions from the developmental stages of primary school pupils were identified and described. An existing instrument of measurement for personality, the Emotions Profile Index (EPI), was adapted and implemented as a new measurement instrument to determine the emotions of primary learners. Questionnaires were completed by the parents of 144 grade 3 and 4 pupils during an empirical investigation. The degree of reliability of the new measurement instrument is particularly high. Stanines were developed for each of the different emotions. The conclusion arrived at is that the education psychologist can implement the newly adapted EPI as diagnostic instrument and conduct the planning of his therapy accordingly / Daar bestaan nie 'n sp sifieke meetinstrument wat primere leerders se emosies kan bepaal nie. 'n Groot behoefte bestaan egter aan s6 'n betroubare meetinstrument. 'n Bestaande meetinstrument vir die meting van persoonlikheid, naamlik die Emotions Profile Index (EPI) is as nuwe meetinstrument vir die meting van emosies van primere leerders aangepas en ge"implementeer. Die vraelyste is tydens 'n empiriese ondersoek deur die ouers van 144 graad 3 en 4 leerders voltooi. Die betroubaarheid van die nuwe meetinstrument is besonder haag en staneges is oak vir die onderskeie emosies, antwerp. Die slotsom waartoe gekom is, is dat die opvoedkundige sielkundige die nuut aangepaste EPI as diagnostiseringsmiddel kan aanwend en sy terapiebeplanning hiervolgens kan doen. / Educational Studies / M.

This study explores approaches and strategies to implement in multicultural English-medium secondary schools for the management and education of black pupils with limited proficiency in English. It attempts to identify means of enhancing and accelerating the mastery by such pupils of English at a level sufficient to support their cognitive-academic needs. An account is given of those elements of the South African education system that have contributed to the disadvantagement that such children bring to the multic,llttu'al classroom. Relevant theories of bilingual education create a theoretical context for the qualitative research that follows, in which the experiences are recorded of educators at three schools where the needs of limited-English-proficient (LEI') pupils have been addressed. Data gathering was by means of focus-group interviews. Based Oll this research, guidelines are offered to help multicultural schools design policies and implement programmes to accommodate the needs of LEP pupils. / Educational Studies / M.Ed.

This study was conducted in order to assess the effects of cognitive stimulation in early childhood. The quantitative study set out to test a target group of 40 children, ranging in age from two years to three and a half years, in order to determine the importance of stimulation and intervention from a young age. A pre-test evaluated the initial level of each child‟s cognitive abilities (mathematics, literacy and life skills). This was followed by a random selection of the subjects into experimental and control groups. The experimental group underwent an eight-week intervention programme which focused on the primary concepts in each area of cognitive development. The control and experimental groups continued with their normal school learning programmes. The results indicate that the impact of stimulation on young children is significant and there is a great difference in the abilities and understanding of concepts for those children which were stimulated individually, as compared with those children who were not so stimulated. / Teacher Education / M.

After independence, in 1990, the government of the Republic of Namibia perceived the need to replace the old Language-in-Education Policy (LiEP) for schools with a new one that promotes the use of the mother tongue alongside English in schools and colleges of education. Consequently, the new Language-in-Education Policy was implemented in all 13 educational regions. The aim of this study is to evaluate the implementation of this policy in the upper primary schools in Oshana Region. The findings of the study were analysed according to relevant literature to determine if they were in line with the theories of language policy evaluation. At least five major findings emerged from this study that are described in relation to relevant themes, namely; home language, language preferences, language practices, policy awareness and government support. The study revealed that the majority of learners in Oshana Region are Oshikwambi speakers, followed by Oshikwanyama speakers. In addition, the majority of teachers who teach Oshindonga are also not Oshindonga speakers. Furthermore, the study revealed that the majority of learners, teachers and principals preferred English as LoLT to Oshiwambo. Another major finding of the study is that despite the fact that English is the LoLT, both teachers and learners are still struggling to communicate in English. In general, successful communication often takes place in Oshiwambo. The study revealed that the majority of teachers, learners and parents are neither aware of the new LiEP nor were they consulted prior to its implementation. In addition, the LiEP related materials are not available in most of the schools. Finally, the study found that there is a serious shortage of textbooks and well qualified teachers in African languages. This shortage of textbooks prevents teachers from giving adequate homework to learners. Consequently, the LiEP cannot be successfully implemented. A number of recommendations are made regarding the shortage of textbooks in Oshiwambo, the use of the mother tongue as LoLT from Grade 1 to Grade 7 and the recognition of other Oshiwambo dialects. Ongoing consultation and awareness should be a vital part of the review process. / Linguistics and Modern Languages / M.A. (Sociolinguistics)

Afrikaans text / Die doel van hierdie studie was om te bepaal wat die invloed van motoriese oefening op die leervermoë van die leerder in die grondslagfase is. Vyf en twintig leerders is ewekansig verdeel in `n eksperimentele en kontrole groep. Oor `n tydperk van vyf weke, voor die aanvang van elke leerafdeling, het die eksperimentele groep, saam met die onderwyseres, klaskamer gebaseerde motoriese oefeninge verrig terwyl die kontrole groep geen intervensie ontvang het nie. Die Copeland’s checklist for Attention Deficit Disorder vraelys is as voor- en natoets gebruik. Na die afloop van die empiriese ondersoek het die eksperimentele groep `n verbetering getoon in onoplettendheid/afleibaarheid, impulsiwiteit, ooraktiwiteit/hiperaktiwiteit, onderaktiwiteit en aandagvermoë, terwyl die kontrole groep oor dieselfde tydperk verswak het of onveranderd gebly het. Die veranderinge was egter nie statisties betekenisvol (p≤0.05) nie. Hierdie resultaat dui slegs op „n tedens dat motoriese oefening 'n positiewe effek op die leerders se leervermoë in die grondslagfase het. / Educational Studies / M. Ed. (Educational Studies)
