Teacher collaboration and educational outcomes in Brazil

ABSTRACT This article started with an inquiry about the extent to which collective teaching work produces different educational results. Thus, its objective was to verify whether teacher collaboration has an impact on students' outcomes and to investigate the various school factors associated with increased teacher collaboration. In this exploratory quantitative study, data from the Prova Brasil of 2017 was used for the fifth grade of municipal and state schools from all over the country. From the answers of the contextual questionnaires, indicators were created and used in linear regressions that estimated the relationship between student proficiency and teacher collaboration, as well as the relationship between the latter and teachers` perceptions of other school factors. The results indicate that greater collaboration among teachers has positive impacts on students’ proficiency and that school factors such as a principal’s leadership, the number of schools where a teacher works, and the perception of students' aggressiveness are associated with greater or lesser collaboration among teachers.
