La Enseñanza del Concepto Tabla Periódica: Una Propuesta desde un Enfoque Histórico

Abstract

The teaching of science from a historical perspective favors a vision and human construction of it, also allows to identify and characterize the tensions, crises, circumstances and contexts in which scientific knowledge has developed. This text describes a didactic sequence, developed with future chemistry teachers, on the periodic table, structured in seven stages. The results allow to note that it is necessary that chemistry teachers in training have a strong historical foundation of the discipline they teach, since it favors the understanding and learning of the contents, increases interest and curiosity about the phenomena, facts and situations themselves of the field of this discipline.
