Moments of professional training for the pedagogical use of information and communication technologies (ICT) aim to promote the integration of the use of ICT in pedagogical practices. In order to contribute to the analysis of results achieved by these training moments, this dissertation presents a study on the relationship between teacher s participation in these moments and his practices with ICT. We investigate the presence of technology in formation and we analyzed public policies of dissemination of ICT in schools. Meanwhile, we conducted a quantitative research to study the correlation between those latent variables: specific training in ICT and used ICT pedagogy on the TIC Educação 2014 data basis. To assign a measure to latent variables, we constructed four scales using the Item Response Theory (IRT). Two of them are training scales: the first one considers the institutionalized moments, while the second one takes the informative information of the assistant teachers into account. The other two are scales of use, one considering the activities with students and the other the actions of preparing classes. In order to explain the dependent variable use of ICT for pedagogy, we composed a linear regression model including as explanatory variables: the specific training variables in ICT and the control variables. The main results indicate that the pedagogical use of ICT is positively influenced by institutionalized and informal training, specific subjects in undergraduate school, family income and academic degree. However, they also show that the pedagogical use is negatively influenced by age, and is not influenced by any specific course, gender and skin colour/race.
