Tabela Periódica on-line colaborativa: vinte elementos químicos aplicados na saúde

Abstract

The traditional approach to teaching the Periodic Table in Chemistry, often centered on the memorization of symbols, atomic numbers, and isolated properties, has shown limitations in promoting effective learning, especially when disconnected from contextualized practical applications. This pedagogical gap may hinder students’ understanding of the role of chemical elements in everyday life and reduce their engagement with the subject. In this context, this study aims to develop, disseminate, and apply an online collaborative Periodic Table, built using the Padlet digital platform, with an initial focus on twenty chemical elements related to the field of health. The educational product was designed to foster active student participation by encouraging research, organization, and sharing of information about the applications of the selected chemical elements, as well as the production of complementary digital content, such as podcasts. The proposal was implemented in a school context and analyzed through a qualitative approach, considering pedagogical, technological, and formative aspects. The results indicate that the use of an online collaborative Periodic Table contributed to increased student engagement, student protagonism, and the contextualization of chemical concepts, promoting more meaningful learning. It is concluded that the use of collaborative digital resources constitutes a viable pedagogical strategy to mitigate the limitations of the traditional approach to the Periodic Table, especially when articulated with socially relevant themes such as health.
