Abstract

This research developed a didactic proposal grounded in the use of 3D modeling and printing as a pedagogical strategy to facilitate the learning of organic addition reactions in high school. The adoption of this approach is justified by its potential to render abstract content more accessible, fostering spatial visualization of molecules and a deeper understanding of reaction mechanisms. Employing a qualitative, descriptive, and case study methodology, the intervention was implemented with 40 students from the third year of high school at a public school in Belém, Pará, Brazil. The proposal was structured in three stages and utilized audio recordings and test responses as data collection instruments, which were analyzed through content analysis and the IRaMuTeQ software. The results indicated that the proposal supported students’ understanding of hydrohalogenation, hydration, and hydrogenation reactions, although a moderate level of comprehension was noted specifically for hydrohalogenation. This study contributes to the field of Chemistry Education by demonstrating that the incorporation of technologies such as 3D modeling and printing can enhance the learning of abstract concepts, stimulate student engagement, and promote active knowledge construction. Further research is recommended to refine and expand the proposal in diverse educational contexts.
