Óculos 3D em Química Orgânica: uma abordagem para a prática extrativa e de identificação do mentol na hortelã (Mentha spicata L.)

Abstract

The teaching of chemistry represents a challenge for both teachers and students, mainly due to its abstract nature, which makes it difficult to understand chemical concepts and phenomena. In this context, technological advancements have provided new possibilities for the teaching-learning process, making it more dynamic and accessible. This study investigates the application of Virtual Reality (VR) and 3D glasses as multimodal resources to facilitate content assimilation in chemistry, exploring multimodality as a pedagogical strategy. To achieve this, an educational 3D video (side by side) was developed, presenting the history of mint (Mentha spicata L.) and the presence of menthol in its leaves, highlighting its application in various everyday products. Furthermore, the video immersively illustrates the experimental process of menthol extraction and identification, allowing students to experience a laboratory setting and actively engage in the experiment. This approach enhances their understanding of concepts through auditory and visual stimuli. The video was presented in three educational settings: to students in a pharmacy technical course at a private school, to students from a state school in Rio de Janeiro, and to undergraduate chemistry students at UFRJ. After watching the video, both students and teachers were invited to anonymously complete a questionnaire with targeted questions. The results demonstrated that using Virtual Reality and 3D glasses as educational tools provided an innovative and effective experience, helping to overcome traditional difficulties in chemistry education. Both students and teachers highlighted the benefits of this approach, underscoring the positive impact of technological advancements in education and their potential to transform pedagogical practices.
