Information and Communication Technology (ICT) in education brings great performances to students, since it allows advances in studies, as the educator makes use of movements such as CTSA (Science, Technology, Society and Environment), which encompasses the current vision about the world and its problems. The objective of this work was to analyze the perception of Biology teachers regarding the use of CTSA in the State Education Network of the Municipalities of Girau do Ponciano and Arapiraca, in addition to analyzing the pedagogical practice of these teachers regarding Ecology content. The research was carried out in six schools of the State Network of Alagoas and the data collection was done through the application of a questionnaire. It was observed that most of the teachers who participated in the research are women trained in Biological Sciences and with different years of experience. The professors stated that they did not have difficulties in using the CTSA in class, whether through interdisciplinarity, whether through the use of the textbook or even through problematizations. Teachers pointed out that Ecology and Science classes are often open to debates and discussion about the role and influences exercised by scientific knowledge in society, as they highlighted the search for technological, social and environmental issues, as well as their relationships, as essential themes for the critical formation of citizens and for being terms addressed in ENEM, among others. It is concluded that the perception of teachers regarding the CTSA approach in teaching Ecology is of paramount importance for the critical formation of students.
