The methodology adopted is qualitative, descriptive, and narrative, based on the experience of a student from the Undergraduate Degree Program in Biological Sciences during the period of supervised internship. The reflection on the teaching-learning process is built from the observation of the pedagogical practices adopted by the intern throughout the internship in the Youth and Adult Education (EJA) context, relating these practices to the challenges faced and the lessons learned along the way. In this context, the research question guiding the study is: How does the supervised internship experience contribute to the process of professional development in Biology teaching? The work engages with authors who discuss the importance of the internship as a formative experience, including Pimenta (2014), Souza (2007), Tardif (2014), and Paulo Freire (1998), who understand the internship as a research field and an organic space between theory and practice in teaching. They emphasize its role in building teaching identity and promoting critical reflection on pedagogical practices, grounded in the principles of continuous training and professional development. Based on the analysis of the experience, it was possible to observe the development of a more critical teaching posture, increasingly aware of the specificities of Science education within the EJA context. The need to adapt pedagogical practices to the characteristics and demands of the class was highlighted, which allowed the intern to develop a deeper understanding of the realities and challenges of education in this setting. Thus, the internship ceases to be a mere application of theories learned during the course and becomes a space for investigation, learning, and transformation — both for students and for the future teacher. It is therefore emphasized that reflection on pedagogical practice is an essential tool for improving teaching performance, acknowledging the contributions and challenges encountered in the professional training and development process of the Biology teacher.ptAttribution-NonCommercial-NoDerivs 3.0 BrazilCiências biológicasBiologia - Ensino aprendizagemEducação de Jovens e Adultos (EJA)Formação acadêmicaAcademic trainingBiology - TeachingProfessional developmentTrabalho de Conclusão de CursoCIENCIAS BIOLOGICAS
