SUMMARY:

This research investigates the role of visuospatial thinking in Organic Chemistry education, taking as its object of study the orientation of action on spatiality and its influence on learning stereoisomerism. The central objective is to analyze this orientation process in high school students from Russas/CEand evaluate its correlation with the assimilation of introductory stereochemistry concepts. Situated in the research context of a full-time public state school, the study addresses the research problem: how does the students' orienting basis regarding spatiality influence their learning of stereoisomerism?The theoretical framework is grounded in the Historical-Cultural Approach, combining Leontiev's Activity Theory, Galperin's Theory of Planned Formation of Mental Actions and Concepts (Galperin's TFPAMC), and Johnstone's Triangle. The methodological assumptions follow a qualitative-quantitative approach inspired by Vygotsky's formative experiment, comprising initial diagnosis via pedagogical testing, planning of the Complete Orienting Basis of Action (SCOBA/EBOCA), and usability evaluation. The educational product developed is MiraCast, a digital game prototype integrating Augmented Reality (AR). Preliminary results indicate a prevailing incomplete Orienting Basis of Action (OBA), with students exhibiting significant difficulties in spatial abstraction, mental rotation, and translating 2D representations into 3D models. The conclusion highlights that intentional pedagogical mediation, coupled with AR and structured game mechanics, serves as an essential scaffold to shift learning from perceptual to mental levels, fostering meaningful and durable stereochemical concept formation.
