Didactic sequence for study of enantiomers

Abstract

This work presents a design and implementation of a didactic sequence (DS) for study of enantiomers in chemistry in high school. In the DS proposed, different pedagogical strategies were thought to achieve the objectives stated. These pedagogical strategies of teaching and learning were focused on reality and interdisciplinary integrated teaching. In this sense, not only were taught new concepts, besides they were related to topic from other subjects, such us symmetry in art, biology and mathematics, thus giving uniqueness and meaning to the study of enantiomers in chemistry. So, the activities were designed to go step by step in the construction of knowledge, following an adequate direction. The different activities allowed the students to develop and strengthen different abilities such as: reading comprehension, writing, solving problematic situations and orality. Students worked and showed their end models of enantiomers. The results showed a high level of dedication and motivation in the part of the students without losing interest during the process.
