This article elucidates the professional dialogue between student teacher and supervisor and it´s conditions as a supervising method in professional academic education. The aim of the study is to discuss how students articulate the conditions of the professional dialogue and the positioning of themselves and supervisors are made. The student taped discussions were analysed. Inspired by positioning theory we analysed the students discussions in order to interpret and elevate patterns showing the conditions concerning the professional dialogues for the students teacher education. The main findings are the students positioning themselves as listener and the supervisor is positioned as communicator of rights, obligations and oughtness. The communicator is positioned to a great number of responsibilities in the professional dialogues and the listener is positioned themselves passive. The professional experienced knowledge and the scientific knowledge will integrate in professional dialogues to challenge the students in their future profession. The contents, form and function of the professional dialogue are situated the students workplace. The conditions of the professional dialogue may vary due to the specific terms that the supervisor have.

Cette recherche s'est donné pour objectif d’étudier le dialogue entre les différents acteurs de la prévention des risques au travail. Ce champ touchant à plusieurs domaines de connaissance, les entreprises cherchent à maîtriser les risques dans une perspective pluridisciplinaire. Cependant, bien qu'il soit important le regard des différents champs de connaissance, plusieurs facteurs font partie des activités d’un collectif qui s'occupe de la prévention : l'interaction entre les membres du groupe, la circulation et le dialogue entre les savoirs des différents acteurs, un rapport de force entre les membres de l’équipe, etc. On a enquêté sur la circulation de savoirs entre les acteurs du CHSCT du Centre NF-B, et leur contribution à la prévention des risques. Pour que cette étude reflète la réalité du travail du CHSCT, on a pris en compte les savoirs constitués (formels) ainsi que les savoirs de l’expérience des acteurs. En s'appuyant sur la démarche ergologique qui considère ces deux formes de savoirs, on a pris en compte le point de vue de ceux qui participent au CHSCT. L’analyse des données a été centrée sur l’évolution du dialogue au fil du temps à propos de certains thèmes. On a constaté que les acteurs rencontrent plusieurs difficultés qui interfèrent dans les dialogues lors de l'accomplissement de leurs missions. Ainsi, on a vu que la circulation et le dialogue entre les savoirs des acteurs apporte des contributions importantes à la prévention et que cette dernière est également favorisée par la manière dont les acteurs surmontent ces obstacles en mettant finalement leurs savoirs en circulation dans l'ensemble du groupe, afin qu'il y ait un dialogue sur ces savoirs. / This research aimed at studying the dialogue between the actors involved in risk prevention at work. As the preventive field covers several areas of knowledge, companies seek to control occupational hazards within a multidisciplinary perspective. However, despite the importance of viewing from various fields of knowledge, several factors are part of the activities of a collective that deals with prevention: the interaction among group members, circulation and dialogue between the knowledge of the actors, a relationship of power among people or groups that make up this team, etc. The circulation of knowledge between the actors of the CHSCT (Committee for Hygiene, Safety and Working Conditions) of NF-B Center and its contribution to risk prevention was taken into account. So that this study could reflect the reality of CHSCT, the established knowledge (formal) and also the knowledge of the actors experience were considered. Relying on ergological approach that considers these two forms of knowledge the point of view of those who participate in the CHSCT was taken into account. Data analysis was focused on the development of the dialogue on certain topics over time. It showed that the actors find various difficulties that interfere in the dialogues that take place in the fulfillment of their missions. Thus, it was seen that the circulation and dialogue between the knowledge of different actors promote risk prevention, and that this is also favored by the way these actors overcome these obstacles, by placing their knowledge ultimately circulating between various actors of the CHSCT, so there may be a dialogue on this knowledge. / O objetivo desta pesquisa foi o de estudar o diálogo entre as diferentes categorias de atores que intervêm na prevenção de riscos no trabalho. Em razão do campo preventivo abranger vários domínios do conhecimento, as empresas procuram controlar os riscos profissionais dentro de uma prespectiva pluridisciplinar. Contudo, apesar da importância do olhar dediversos campos do conhecimento, observou-se que vários fatores fazem parte das atividades de um coletivo que se ocupa da prevenção, como: a interação entre os membros do grupo, a circulação e o diálogo entre os saberes dos diferentes atores, uma relação de forças entre as pessoas ou os grupos que constituem esta equipe, etc. Investigou-se a circulação de saberes entre o diferentes atores do Comité de higiene, segurança e condições de trabalho (CHSCT)do Centro NF-B e sua contribuição na prevenção de riscos. Este CHCT é composto de atores que representam disciplinas e profissões diferentes e de vários níveis hierárquicos. Para que este estudo refletisse a realidade do trabalho do CHSCT, levou-se em conta os saberes contituídos (formais) e também os saberes da experiência dos atores. Apoiando-se naabordagem ergológica, que considera estas duas formas de saberes, levou-se em conta o ponto de vista daqueles que participam do CHSCT. A análise de dados foi centarada na evolução do diálogo sobre certos temas, ao longo do tempo. Constatou-se que os atores encontram várias dificuldades que interferem nos diálogos que se estabelecem no cumprimento de suas missões. Assim, viu-se que a circulação e o dialogo entre os saberes dos diferentes atores favorecem a prevenção de riscos e que, esta é também favorecida, pela a maneira como os atores superam esses obstáculos colocando, finalmente, seus saberes em circulação entre os diversos atores do CHSCT, para que, assim, haja um dialogo sobre esses saberes.
