I worked with children and young people in public schools in the state of São Paulo, where there is a need for better preparation for entering universities and the job market. My mission was to educate these students scientifically and technologically, developing the skills and knowledge necessary for their academic and professional future.To achieve this goal, I developed students' critical thinking in the Science discipline, teaching them to think like scientists and to apply the scientific method in their daily lives. Additionally, I taught basic programming in the Technology discipline using intuitive and didactic codes with the SCRATCH and Python platforms, facilitating the understanding and application of technological concepts. This approach not only improves students' ability to adapt to the university environment and the job market, but also promotes a deeper understanding of science and technology, preparing them to face future challenges.

The "CEC" Preparatory Course is a preparatory course for college entrance exams where undergraduate students teach classes to help low-income people get into universities. I initially worked as a grammar teacher, and then I took part in the coordination, helping other teachers and organizing the smooth running and development of the preparatory course. We managed to keep the preparatory course organized even during the pandemic, and we helped many students get into universities, including UFSCar itself.
