Activities about the chemical nomenclature and notation of the inorganic substances (Original)

Abstract

In the chemical subject, knowing how to name and formulate substances is vital content in pre -university education. Taking into account the insufficiencies that are presented in 10th grade students of the Julio Antonio Mella Urban University Institute, this research is carried out: the elaboration of activities for the treatment of nomenclature and notation Chemicals of inorganic substances, from the process of teaching chemistry learning, so that it favors the integral training of students. Methodology: Research is carried out using theoretical, empirical and mathematical - statistical methods, which allowed determining the scientific problem and drawing the proposal that allows solving insufficiencies on how to name and formulate chemical substances in a sample of 24 grade students. The proposal can be novel because it allows the teaching of this content not only from the curricular part, but in the relationship between chemical nomenclature and notation and its application for life, contextualized to domestic, popular and extracurricular. Conclusions: With the application of the set of activities, students enhanced their skills to name and formulate simple and compound inorganic substances, in an independent way, achieving comprehensive training, prepared to face daily dynamics and Understanding the phenomena and changes that occurred in practical life and nature, also contributes to developing a scientific conception of the world and enhancing chemical language.
