Therefore, addressing this issue becomes relevant because, in addition to this worrying characteristic, these compounds are part of the so-called organic halides, one of the organic functions studied in chemistry. In this context, it is necessary to find ways to make teaching more effective, since there are problems faced by teachers and students in the teaching and learning process. Thus, the use of active methodologies, such as the Flipped Classroom, emerges as fundamental, as it gives importance to the student, highlighting them in this process. Linked to this, the use of 3D models as a teaching resource stands out, an alternative that aims at building practical representations of theoretical concepts. Furthermore, this resource becomes relevant because students participate in the model-building process, which generates a unique and enriching experience. Therefore, this research aimed to analyze how a didactic sequence, based on the flipped classroom model, using 3D printing, can contribute to the teaching and learning process of organic halides. The study is characterized by adopting a qualitative approach, using the case study method as a research method. The intervention took place in a public school located in the municipality of Belém-PA, in a third- year high school class, with 25 participants. As an Educational Product (EP), entitled "Exploring Chemistry through the Flipped Classroom and 3D Printing: a proposal for teaching organic halides," a Didactic Guide was developed, composed of the concepts of organic halides and organochlorine compounds, the theoretical-methodological references of the research, along with the steps developed for the execution of the Didactic Sequence, as well as the methodological path used for the construction and printing of 3D molecules. The EP was evaluated by a panel of experts composed of chemistry teachers working in 3rd-year high school classes. The research data were analyzed using Content Analysis, the results of which point to the potential of the dynamics established by combining the Flipped Classroom and 3D Printing. Furthermore, the theoretical concepts involving organic halides and organochlorine compounds were understood and had a significant impact on the students, as they identified and understood the socio-environmental problems arising from organochlorine compounds and observed them in their own realities. Moreover, the 3D printing process allowed unique experiences such as understanding the function of printing and modeling programs, the interaction between theory and practice, and the visualization of concepts in a tactile and immersive way. Furthermore, it is hoped that teachers can use the proposed idea, applying it in their contexts of practice, to promote more productive teaching.PPGEECA - Estratégias educativas para o ensino de ciências naturais na Amazônia
