Ethos empresarial na prescrição do trabalho: discursos do poder em manuais de integração

Borim, Rosileia Aparecida 19 September 2006 (has links)
Made available in DSpace on 2016-04-28T18:23:20Z (GMT). No. of bitstreams: 1 CD 1 - LAEL - Rosileia Ap Borim.pdf: 780796 bytes, checksum: 9b9ef3994a7c38fad3a09ac4061ee610 (MD5) Previous issue date: 2006-09-19 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / Nowadays, one of the things most often seen in big companies is executives and managers searching the perfect client services. In order to achieve this objective, corporations invest in training their employees, as their conduct reflects the company s image. In this sense, this work paper, originated from a personal demand, aims at understanding how the company s ethos in the interaction with the employee is built, through the Integration Manuals of a hotel. These Manuals that comprise our corpus are supplied as a guide to the employees entering the company, determining how they should be, do, walk, speak, act and look during work. As noted, through working writings, these Manuals try to anticipate the possible answers, attitudes e situations which may arise during the performance of their activities. Although this research is for a master degree paper, based on the Applied Linguistics area and linked to the research line Speech and Work (Group Atelier), the first part of this paper is dedicated to providing a general overview of the beginning of worldwide hotel and tourism activities. Subsequently, a summarized profile of the concerning company, as related to the way it s structured regarding personnel and types of guests it works with, will be provided. In addition, we will describe how the service standardization process was carried out, which developed into the Manuals. To answer our research question, speech, work and power studies will be employed. As theoretical assumptions of the speech studies, the scenography notions (Maingueneau, 1997,2002) and all their constitutive analysis categories, such as: personal marks (ibidem); topography and chronography (ibidem); modalities (Cervoni, 1989) will be used and, in the case of this research, negation will also be considered (Ducrot, 1987). Another notion used will be ethos (Maingueneau, 1997,2002). In the work studies, as regards to the ergonomy, speech and work notions of Boutet (1993, 1998) will be used to discuss the different speech manifestations in the professional context, and Daniellou (2002), to grasp the different prescription levels present in work. As regards to ergology (Schwartz, 1998,2000), the notions of value conflict and debate , uses of self by self and by others will be discussed, allowing us to observe how the Manuals, in this company, build the idea of employee, in other words, how this employee is understood and/or viewed. As to the power study, the studies developed by Foucault (1997) will be employed, once we will discuss the different ways de instituting power through the written language present in the Manuals. The methodology adopted for this work paper arises from the discourse analysis of the Manuals. The analyses will be carried out based on the articulation among the speech, power and work studies categories. These articulations allowed us to reach the following conclusions: (a) the several procedures used by the enunciator to interact with its co-enunciator; (b) the multiple functions assigned to the speakers; (c) the presence of physical, cognitive and psychical workload, (d) the employee in this company is seen as a passive subject, without voice; (e) the organizational perspective shifts in the opposite direction of ergonomy, that is to adapt work to man and not man to work; (f) the many manifestations of cognitive, social and instrumental language/speech in work; (g) different ways of power construction, e (h) different levels of prescriptions present in work / Atualmente, o que mais vemos nas grandes empresas é a preocupação por parte dos chefes e responsáveis com a busca da perfeição dos serviços prestados aos clientes. Para que atinjam este objetivo, as corporações investem em treinamentos para seus funcionários, uma vez que a conduta destes reflete a imagem da empresa. Neste sentido, este trabalho, que parte de uma demanda pessoal, tem como objetivo depreender como se constrói o ethos da empresa na interação com o funcionário, por meio dos Manuais de Integração de uma empresa hoteleira. Estes Manuais que constituem nosso corpus servem como um guia para os funcionários que estão sendo admitidos na empresa, orientando-os quanto à sua maneira de ser, fazer, andar, dizer, agir, olhar e estar no trabalho. Como percebemos, trata-se de Manuais que, por meio dos escritos para trabalhar, tentam abarcar as possíveis respostas, atitudes e situações que poderão ocorrer no desenvolvimento de suas atividades. Embora esta pesquisa pertença a um trabalho de dissertação de mestrado, alicerçada na área de Lingüística Aplicada e vinculada à linha de pesquisa Linguagem e Trabalho (Grupo Atelier), a primeira parte desta dissertação será dedicada a fornecer um panorama geral sobre o surgimento da atividade hoteleira e turística mundial. Logo após, forneceremos um breve perfil da empresa em questão, no que concerne à forma como esta se encontra estruturada quanto ao quadro de funcionários e tipos de hóspedes que recebe. Falaremos, também, como se deu o processo de padronização dos serviços, o que resultou no surgimento dos Manuais. Para responder à nossa pergunta de pesquisa, utilizaremo-nos dos estudos da Linguagem, do Trabalho e do Poder. Como pressupostos teóricos dos estudos da linguagem, privilegiaremos as noções de cenografia (Maingueneau, 1997,2002) e todas as categorias de análise que a constitui, como: marcas de pessoa (ibidem); topografia e cronografia (ibidem); modalidades (Cervoni, 1989) e, no caso desta pesquisa, consideraremos também a negação (Ducrot, 1987). Outra noção utilizada será a de ethos (Maingueneau, 1997,2002). Nos estudos do trabalho, no que tange à ergonomia situada, utilizaremos as noções de linguagem no trabalho de Boutet (1993,1998) para discutir as diferentes manifestações da linguagem em contexto profissional e Daniellou (2002) para depreendermos os diferentes níveis de prescrições presentes no trabalho. Referente à ergologia (Schwartz, 1998,2000), serão discutidas as noções de conflito e debate de valores , usos de si por si e usos de si pelos outros que nos permitirão observar de que modo os Manuais, nesta empresa, constróem a idéia de funcionário, em outras palavras, depreender como este funcionário é entendido e/ou visto. Já no que se refere ao estudo sobre o poder, utilizaremo-nos dos estudos desenvolvidos por Foucault (1997), uma vez que iremos discutir as diferentes formas de instituir poder através da linguagem escrita presente nos Manuais. A metodologia adotada neste trabalho provém da análise discursiva dos Manuais. As análises serão feitas a partir da articulação entre as categorias dos estudos da linguagem, do poder e do trabalho. Estas articulações nos possibilitaram chegar às seguintes conclusões: (a) os vários procedimentos utilizados pelo enunciador para interagir com seu co-enunciador; (b) as múltiplas funções atribuídas aos interlocutores; (c) a presença da carga de trabalho física, cognitiva e psíquica; (d) o funcionário nesta empresa é visto como um sujeito passivo, que não tem voz; (e) a perspectiva organizacional desloca-se na contramão da ergonomia, que é adaptar o trabalho ao homem e não o homem ao trabalho; (f) as várias manifestações da linguagem cognitiva, social e instrumental no trabalho; (g) diferentes formas de fabricação do poder e (h) diferentes níveis de prescritos presentes no trabalho

ESTRATÉGIAS COMUNICACIONAIS DE INTERFACES GRÁFICAS DE WEBJORNAIS: Estudo do Caso ZERO HORA.com / COMMUNICATIONAL STRATEGIES OF WEB JOURNALS GRAPHICAL INTERFACES: A case study of ZERO HORA.com

Grossmann, Fabiane Volkmer 05 March 2008 (has links)
With the purpose of noticing the occurrence of communication strategies in graphical interfaces (GI) of webjornals of fourth generation, this dissertation initiates the research considering GI as a mediator space which materializes the elements of humancomputer-human interaction grammar. The subject in focus is that such possibility for webjournals of fourth generation be thought in terms of communicational strategies applied in the creation of their GI as interagent captation strategies, not only in terms of metaphors, as it has been often seen in academic studies conducted so far. Throughout three chapters of literature review, three main reflections are carried out: a)one reflection which provides a different function to GI; b) another which identifies characteristics that classify the webjornal in a current fourth generation; and c) another reflection which proposes ways of materializing communication strategies, specifically strategies aimed at capturing the interagent. Such reflections are supported by theories of communication, midiatic communication, communicational strategies, interface design, and ergonomics. The discussion which that follows the theoretical construct is contextualized by the analysis of data obtained by the case study research methodology. The case study example, ZERO HORA.com, allowed some considerations to be outlined, which pointed NBR-9241 (following ISO-9241 recommendations, especially part 11, which deals with issues relating to the usability of systems) as a way to be taken towards the materialization of interagent captation strategies in the webjournals GI conception. / Com o objetivo de constatar a presença de estratégias comunicacionais em interfaces gráficas (IG) de webjornais de quarta geração, a presente dissertação de mestrado inicia a investigação considerando IG como um espaço mediador que materializa os elementos da gramática de interação humano-computador-humano. A questão em foco é que tal possibilidade para webjornais de quarta geração seja pensada em termos de estratégias comunicacionais aplicadas à elaboração de suas IG na forma de estratégias de captação do interagente e não apenas em termos de metáforas como vem sendo freqüentemente considerado em estudos acadêmicos realizados até agora. Ao longo de três capítulos de revisão bibliográfica são realizadas três principais reflexões: a) uma que atribui uma outra função à IG; b) outra que identifica características que classificam o webjornal em uma atual quarta geração e c) e a que propõe formas de materialização de estratégias de comunicação, especificamente de estratégias que visam captar o interagente. Tais reflexões são fundamentadas pelas teorias da comunicação, da comunicação midiática, de estratégias comunicacionais, do design de interface e da ergonomia. As discussões que sucedem à fundamentação teórica são contextualizadas pela análise dos dados obtidos por intermédio da metodologia de pesquisa de estudo do caso. O exemplo do estudo do caso ZERO HORA.com permitiu que fossem delineadas algumas considerações finais que apontaram a NBR-9241 (seguindo recomendações da ISSO-9241, especialmente a parte 11 que trata das questões referentes à usabilidade de sistemas informáticos) como um caminho a ser tomado rumo à materialização de estratégias de captação de interagentes na elaboração de IG de webjornais.

A pesquisa estuda as condições microclimáticas e morfológicas, relacionando-as com a quantidade e a qualidade de uso para conhecer as influências dessas variáveis no comportamento dos usuários. Para isso, utilizou-se como estudo de caso três vias de Bauru, SP, espaços públicos de grande importância para a cidade, que apresentam diferentes aspectos e diversos tipos de uso. Utilizou-se uma metodologia adaptada que considerou dados quantitativos e também qualitativos, fazendo-se uso também de entrevistas para se conhecer o perfil do usuário e seu grau de satisfação. Os resultados evidenciam a relação entre uso e microclima, bem como entre o uso e outras características peculiares de cada espaço, identificando aspectos positivos e negativos. Objetivou-se também, contribuir com dados que subsidiem intervenções projetuais nos espaços analisados ou em áreas similares. Assim, mostrou-se que o profissional de planejamento deve dedicar especial atenção ao comportamento microclimático gerado com a morfologia como determinantes da qualidade do uso, em garantia do sucesso do espaço público / This work analyses the public space under some aspects of ergonomy in urban scale by post-occupation evaluation system based on user’s behavior and thermal comfort. The research studies the microclimate and morphological conditions, doing relations with the quantity and quality of the uses to know the influences of these variables on users’ behaviors. Then were studied three roads in Bauru, SP, public spaces with great importance for the city, which presents different aspects and various kind of use. An adapted methodology was used to consider quantitative data and also the qualitative ones, doing interviews to know the users’ profile and your opinion about the place. The results showed a relationship between use and microclimate, as well as between use and other characteristics of each space, identifying positives and negatives aspects. This study also means to contribute with data to provide information for intervention at the studied spaces or similar areas. Then, the planner must dedicate special attention to the microclimate behavior produced by the morphology like important motive of quality use in this way guarantee the success of the public space

The effect of "Postural Freedom" in laparoscopic surgery

Pace Bedetti, Horacio Martin 17 June 2019 (has links)
[ES] La cirugía laparoscopia está considerada uno de los principales avances quirúrgicos en las últimas décadas. Esta técnica ha demostrado numerosas ventajas comparadas con la cirugía convencional abierta y ha sido extensamente usada para procesos quirúrgicos en el área abdominal. Para el paciente, la cirugía laparoscópica supone diversas ventajas, como por ejemplo menor dolor post operativo, tiempos de recuperación menores, menor riesgo de infección, o reducción del trauma. Para el cirujano en cambio, la situación es completamente diferente, esta práctica requiere mayor esfuerzo, concentración y estrés mental que la práctica convencional abierta. Además fuerza al cirujano a adoptar posiciones no-neutras en falanges, manos, muñecas, y brazos. Estas posturas no-neutras son la principal causa de fatiga muscular y aumentan el riesgo de problemas musculo-esqueléticos. Estos problemas han sido ampliamente estudiados por diferentes equipos de investigación, los cuales están tratando de mejorar la experiencia del cirujano en el quirófano. El enfoque utilizado en este estudio es diferente del utilizado anteriormente por la mayoría de estos equipos, los cuales suelen propones soluciones basadas en cambios ergonómicos con la intención de mejorar la geometría del mango de pistola convencional, ya que se considera ergonómicamente deficiente. El problema con este enfoque, es que las deficiencias no se encuentran únicamente en el mango, sino en la utilización de un punto de entrada fijo que fuerza a los cirujanos a mantener posiciones desfavorables. En este trabajo, se introduce el concepto "Libertad Postural" en el ámbito de la cirugía, este se basa en la hipótesis de que, si las herramientas no forzaran la posición de los cirujanos, estos mantendrían posiciones más favorables y cercanas al rango de posiciones neutras durante los procesos laparoscópicos. Los beneficios de este concepto han sido demostrados por medio de análisis de movimiento y de electromiografía de superficie, los cuales indican que la "Libertad Postural" es causante de un claro aumento de las posiciones neutras y de la reducción de la fatiga muscular, y han sido testeados por cirujanos en entornos simulados, los cuales encuentran beneficioso utilizar la "Libertad Postural" como característica base de este nuevo diseño de herramienta laparoscópica. En la sección final de este trabajo se propone un diseño que implementa el concepto de libertad postura con el cual se reduciría la fatiga muscular y los problemas musculo esqueléticos asociados a la práctica laparoscópica. Este diseño tiene la característica de actuar como una nueva sección del brazo, siendo una articulación que soporta los giros y grandes desplazamientos que normalmente tienen que desarrollar los brazos del cirujano. Además, esta solución es económica y fácil de fabricar, lo cual permitiría su uso por cirujanos de todo el mundo. / [CAT] La cirurgia laparoscòpia està considerada un dels principals avanços quirúrgics en les últimes dècades. Aquesta tècnica ha demostrat nombrosos avantatges comparats amb la cirurgia convencional oberta i ha sigut extensament usada per a processos quirúrgics en l'àrea abdominal. Per al pacient, la cirurgia laparoscòpica suposa diversos avantatges, com per exemple menor dolor post operatiu, temps de recuperació menors, menor risc d'infecció, o reducció del trauma. Per al cirurgià en canvi, la situació és completament diferent, aquesta pràctica requereix major esforç, concentració i estrés mental que la pràctica convencional oberta. A més força al cirurgià a adoptar posicions no-neutres en falanges, mans, nines, i braços. Aquestes postures no-neutres són la principal causa de fatiga muscular i augmenten el risc de problemes musculo-esquelètics. Aquests problemes han sigut àmpliament estudiats per diferents equips d'investigació, els quals estan tractant de millorar l'experiència del cirurgià en el quiròfan. L'enfocament utilitzat en aquest estudi és diferent de l'utilitzat anteriorment per la majoria d'aquests equips, els quals solen proposes solucions basades en canvis ergonòmics amb la intenció de millorar la geometria del mànec de pistola convencional, ja que es considera ergonòmicament deficient. El problema amb aquest enfocament, és que les deficiències no es troben únicament en el mànec, sinó en la utilització d'un punt d'entrada fix que força als cirurgians a mantindre posicions desfavorables. En aquest treball, s'introdueix el concepte "Llibertat Postural" en l'àmbit de la cirurgia, aquest es basa en la hipòtesi que, si les eines no forçaren la posició dels cirurgians, aquests mantindrien posicions més favorables i pròximes al rang de posicions neutres durant els processos laparoscòpics. Els beneficis d'aquest concepte han sigut demostrats per mitjà d'anàlisi de moviment i de electromiografía de superfície, els quals indiquen que la "Llibertat Postural" és causant d'un clar augment de les posicions neutres i de la reducció de la fatiga muscular, i han sigut testats per cirurgians en entorns simulats, els quals troben beneficiós utilitzar la "Llibertat Postural" com a característica base d'aquest nou disseny d'eina laparoscòpica. En la secció final d'aquest treball es proposa un disseny que implementa el concepte de llibertat postura amb el qual es reduiria la fatiga muscular i els problemes *musculo esquelètics associats a la pràctica laparoscòpica. Aquest disseny té la característica d'actuar com una nova secció del braç, sent una articulació que suporta els girs i grans desplaçaments que normalment han de desenvolupar els braços del cirurgià. A més, aquesta solució és econòmica i fàcil de fabricar, la qual cosa permetria el seu ús per cirurgians de tot el món. / [EN] Laparoscopic surgery is considered one of the main surgical advances in the last decades, this technique has demonstrated numerous advantages compared to open conventional surgery and it is widely used in abdominal procedures around the world. For the patient, laparoscopic surgery suppose less post-operative pain, shorter recovery time, lower risk of infection, and reduction of the trauma among other benefits. For the surgeon, the situation is completely different, this practice requires more effort, concentration and mental stress than conventional open procedures. It forces the surgeon to adopt non-neutral postures with phalanges, hands, wrists, and arms being this non-neutral postures the main cause of muscular fatigue and high risk of musculoskeletal disorders. The poor ergonomic postures accelerate muscle fatigue and pain because, outside the neutral range, muscles require more energy to generate the same contractile force than in neutral position. This increase of muscular fatigue is associated with the potential to commit errors that may harm the patient during the surgery. Because this problem is widely studied and different research centers are already trying to improve their surgeons experience in the operation room, the approach used during this work is different than most of the ones presented in previous works. Generally, the solutions proposed are based on ergonomic changes in the handle shape of the instrument, because the conventional pistol-grip handle is considered ergonomically poor. But the problem is not only in the shape of the handle but also in the fixed point of entrance that force the positions for the surgeon despite the handle¿s shape. In this work, the concept of postural freedom in laparoscopic surgery is introduced and evaluated. The postural freedom concept is based on the hypothesis that the surgeon involuntarily would maintain neutral postures if the instrument does not force him or her to reach extreme position with the upper limbs. The benefits of this concept has been demonstrated, by means of electromyography and motion capture. It reduces the localized muscular fatigue and increases the number of neutral postures during laparoscopic simulations. In the final section it is proposed a design that implements the postural freedom concept with, according on the results, the potential to reduce the localized muscular fatigue and the musculoskeletal problems associated to the practice. The design proposed here acts as a new section on the arm, being an articulation that support the turns and big displacements that currently suffer the surgeon¿s body. The solution is affordable and easy to manufacture and could be used by surgeons worldwide. / Pace Bedetti, HM. (2019).

Lecture de l’heure et incapacités intellectuelles : Cahier des Charges d’un cadran évolutif

Robichaud, Paul 11 1900 (has links)
La présente étude s’inscrit à l’intérieur du programme de recherche mené par le Groupe DÉFI Apprentissage (GDA) de l’Université de Montréal. Notre projet avait pour buts de réaliser les deux premières phases précédant la conception d’une ressource pédagogique qui offrira à l’enfant (6 à 12 ans qui a des incapacités intellectuelles) et à son entourage un dispositif temporel évolutif pour l’initier à la lecture de l’heure et à la gestion des activités de son horaire quotidien à l’âge approprié. Depuis quelques années, maints organismes tels que l’American Association on Mental Retardation (AAMR) , la Classification internationale des déficiences, incapacités et handicaps (CIDIH) de l'Organisation Mondiale de la Santé (OMS), le Ministère de l’éducation, des loisirs et des sports du Québec (MELS) ainsi que le Réseau international sur le processus de production du handicap (RIPPH) soutiennent que les chercheurs doivent s’attarder aux composantes impliquées dans l’interaction Personne-Milieu pour concevoir des stratégies d’intervention auprès de diverses populations qui éprouvent des limitations. Notre recherche adoptera cette démarche en s’appuyant sur les assises suivantes : cadre méthodologique (analyse de la valeur pédagogique), cadre conceptuel (écologie de l’éducation et processus de production du handicap) et cadre technologique (ergonomie). / The present study is part of an ongoing research program which has been undertaken by the « Groupe DÉFI Apprentissage (GDA) » at « l’Université de Montréal ». Our precise mandate was to complete the two initial phases preceding the conception of a pedagogical ressource that will offer to a child (6 to 12 years old with intellectual disabilities) and to his immediate surrounding an evolutionary temporal device that will initiate him, at the appropriate age, to time telling and to daily schedule management. In recent years, a number of organizations such as the American Association on Mental Retardation (AAMR), the World Health Organization (WHO) the Ministère de l’éducation, du loisir et du sport du Québec (MEL) and the Réseau International sur le Processus de Production du Handicap (RIPPH) have recommended that researchers should take into account the components involved in the Person-Environment interaction when they are studying intervention strategies that could be used by people with various limitations. Our research has adopted this ecological approach and it will be supported by the following foundations: methodological approach (pedagogical value analysis), conceptual approach (educational ecology) and technological approach (ergonomics).

L'enseignement des langues vivantes étrangères à l'école primaire : Analyse ergonomique de l’activité des maîtres et instauration d’une médiation formative dans l’établissement / Teaching of foreign languages in primary school : Ergonomic analysis of the activity of the school teachers and introducing a formative mediation in the establishment.

Clémens Corbi, Christine 03 July 2014 (has links)
Cette thèse montre en quoi l'analyse de l'activité des professeurs des écoles enseignant une Langue Vivante Etrangère peut apporter des connaissances utiles au processus de formation continue de ces maîtres au sein de leur polyvalence. L'activité humaine est invisible tant pour les observateurs que pour les acteurs eux-mêmes, d'où notre recours au cadre théorique et méthodologique de l'analyse ergonomique de l'activité enseignante qui s'inscrit dans une perspective historico-culturelle et se nourrit des apports féconds d'une clinique de l'activité. La Méthode d'Auto Confrontation, méthode indirecte, nous permet la création d'un milieu spécifique où nous prenons en compte l'expérience des enseignants et où nous cherchons à transformer le travail pour le comprendre. Nous nous sommes appuyés sur l'analyse de l'activité de six enseignants engagés dans l'enseignement de l'anglais afin de rendre compte de leurs manières de faire, des arbitrages et compromis à l'oeuvre. Une première représentation des pratiques enseignantes laisse ainsi apparaître trois registres d'action principaux liés à leur maîtrise de la conduite de classe, à leur connaissance de la démarche didactique et pédagogique de l'enseignement des LVE et à leur maîtrise de la langue cible. Un processus spécifique lié à la confiance en soi a émergé en cours d'analyse et joue un rôle central dans leur activité. Un nouvel éclairage de la polyvalence est alors envisagé où nous proposons une rencontre entre analyse du travail et formation. La « mise en situation active » (MSA) décline les perspectives découlant de la visée technologique de notre recherche. / This thesis shows how the analysis of the activity of the school teachers teaching a Foreign Language can bring useful knowledge to the process of ongoing training to these teachers within the core of their versatility. Human activity is invisible as much for the observers as for the actors themselves, which leads us to fall back on the theoretical and methodological frameworks of the ergonomic teaching activity which joins a historical-cultural perspective and is fed by the fertile contributions of a clinic of activity. The method of Self-Confrontation, an indirect method, allows us to create a specific space where we take into account the experience of the teachers and where we seek to transform the work in order to understand it. We turned to the analysis of the activity of six teachers engaged in the teaching of English in order to report on their methods, their judgments and compromises in action. A primary representation of their teaching practices thus allows three principle registers of action linked to their mastery of classroom management, to their knowledge of the didactic and pedagogical process of the teaching of Foreign Languages and their mastery of the target language. A specific process linked to self-confidence emerged during the course of the study and played a central role in their activity. A new understanding of versatility is thus envisioned where we propose to link the work analysis and training. The "put into live action" breaks down the perspectives coming from our targeted online research.

Lecture de l’heure et incapacités intellectuelles : Cahier des Charges d’un cadran évolutif

Robichaud, Paul 11 1900 (has links)
La présente étude s’inscrit à l’intérieur du programme de recherche mené par le Groupe DÉFI Apprentissage (GDA) de l’Université de Montréal. Notre projet avait pour buts de réaliser les deux premières phases précédant la conception d’une ressource pédagogique qui offrira à l’enfant (6 à 12 ans qui a des incapacités intellectuelles) et à son entourage un dispositif temporel évolutif pour l’initier à la lecture de l’heure et à la gestion des activités de son horaire quotidien à l’âge approprié. Depuis quelques années, maints organismes tels que l’American Association on Mental Retardation (AAMR) , la Classification internationale des déficiences, incapacités et handicaps (CIDIH) de l'Organisation Mondiale de la Santé (OMS), le Ministère de l’éducation, des loisirs et des sports du Québec (MELS) ainsi que le Réseau international sur le processus de production du handicap (RIPPH) soutiennent que les chercheurs doivent s’attarder aux composantes impliquées dans l’interaction Personne-Milieu pour concevoir des stratégies d’intervention auprès de diverses populations qui éprouvent des limitations. Notre recherche adoptera cette démarche en s’appuyant sur les assises suivantes : cadre méthodologique (analyse de la valeur pédagogique), cadre conceptuel (écologie de l’éducation et processus de production du handicap) et cadre technologique (ergonomie). / The present study is part of an ongoing research program which has been undertaken by the « Groupe DÉFI Apprentissage (GDA) » at « l’Université de Montréal ». Our precise mandate was to complete the two initial phases preceding the conception of a pedagogical ressource that will offer to a child (6 to 12 years old with intellectual disabilities) and to his immediate surrounding an evolutionary temporal device that will initiate him, at the appropriate age, to time telling and to daily schedule management. In recent years, a number of organizations such as the American Association on Mental Retardation (AAMR), the World Health Organization (WHO) the Ministère de l’éducation, du loisir et du sport du Québec (MEL) and the Réseau International sur le Processus de Production du Handicap (RIPPH) have recommended that researchers should take into account the components involved in the Person-Environment interaction when they are studying intervention strategies that could be used by people with various limitations. Our research has adopted this ecological approach and it will be supported by the following foundations: methodological approach (pedagogical value analysis), conceptual approach (educational ecology) and technological approach (ergonomics).
