Terras raras numa abordagem CTSA: elaboração de material didático para o ensino de Química

Abstract

Teaching Chemistry from a CTSA perspective has proven to be quite effective, since it makes it possible to make the program content more relevant and engaging for students, showing them how Chemistry is intrinsically linked to everyday life. By adopting the theme “Rare Earths” the objective was to use a highly relevant scientific and technological topic that has not yet been widely discussed, aiming at a greater understanding of chemical content by students, in addition to enabling the development of critical knowledge about the impact that the use of these elements has on society. In this context, for the development of this research, qualitative methodology and production of teaching material were used. Thus, the procedural steps were, in addition to bibliographic research, the preparation of a teaching material consisting of a booklet and a teaching game. The booklet structured important chemical information about rare earth elements, enabling its use to explain various chemical contents, as well as the application of the elements of this group in current technologies. The content was presented in a dynamic language that was easy to understand and comprehend for the target audience, which is made up of first-year high school students. The development of this research highlights the importance of relating the program content to everyday life with the aim of improving student involvement in classes and thus facilitating the teaching-learning process, thus bringing satisfactory results for efficient learning.
