LIMA DOS SANTOS, José Carlos  e  KO. FREITAG, Raquel Meister. LINGUISTIC CONSTRUCTION OF POWER RELATIONS IN COMMUNITIES OF PRACTICE: CONTROL OF TOPICS AND KNOWLEDGE. Forma funcion, Santaf, de Bogot, D.C. [online]. 2013, vol.26, n.2, pp.57-75. ISSN 0120-338X.

The classroom is a community of practice in which several factors of a different order converge and diverge, on the basis of a power relation established between the professor and the student by means of an asymmetric discourse. However, it is also a space that is being constantly built through the practices of interaction between its protagonists: students and professors. For this study, we analyzed 10 high school science classes, focusing our attention on interaction and topic control strategies. The data show that the professor controls the discursive topic due to his/her institutional power, and that such control is made effective through questions, thus giving rise to the construction of knowledge in the classroom.

Palavras-chave : classroom; communities of practice; control of the topic; power relations.
