%0 Journal Article %T The dynamics of a students¡ä groupwork in the Physics classes, their relationship to the knowledge, and the teacher¡äs interventions %A Glauco S. F. da Silva %A Alberto Villani %J Investiga£¿£¿es em Ensino de Ci¨ºncias %D 2012 %I Universidade Federal do Rio Grande do Sul %X We present the learning-teaching process case of a group of High School students and emphasize their relation with physics subject-matter, the interventions of the teacher (presential and institutional) and the difficult situations faced by them within the group. We used Pichon-Rivi¨¨re¡¯s theory of operative groups to analyze this data. In this theory, some important elements are: the task of the group, the bond and the roles the members play. We made a diachronical analysis of the group, raising the hypothesis of the dependence from the teacher, and we made a synchronical analysis from one class to reveal some details of the group process. We concluded that the members¡¯ dependence was related to ¡°not knowing Physics¡± whose teacher was the one who could solve their problems. Lastly, we discuss teacher¡¯s intervention function in a students¡¯groupwork during physics classes. %K groupwork process %K operative group %K teacher¡äs interventions %K physics teaching %U http://www.if.ufrgs.br/ienci/artigos/Artigo_ID289/v17_n1_a2012.pdf
