USE OF ELECTRONIC DISTRIBUTION AS AN ALTERNATIVE STRATEGY FOR THE REPRESENTATION AND UNDERSTANDING OF INORGANIC COMPOUNDS.

Abstract

The current research, titled "Using electronic distribution as an alternative strategy for the representation and understanding of inorganic compounds." The choice of topic arose from the need observed among 11th-grade students at the Uíge High School, a secondary education school in Angola. The study aimed to apply an alternative didactic strategy for the representation of inorganic compounds, using electronic distribution as a pedagogical resource. The proposal originated from the difficulties identified among students in representing chemical formulas, an essential content for understanding Chemistry, but often approached in an excessively theoretical manner and based on memorization. In light of this scenario, the following research question was formulated: How to contribute to improving the skills of 11th-grade students in representing chemical formulas? In response, the study proposed the development of an alternative strategy based on algorithmic steps. The adopted methodology was of a bibliographic nature, with an exploratory and statistical-mathematical approach, using techniques such as questionnaire surveys, observation, and document analysis. The implementation of the strategy took place through experimental classes, starting with a diagnostic test and ending with a prognostic test. The data analysis revealed two main results: (i) there are significant deficiencies in the teaching of chemical formulas; and (ii) students showed relevant improvements in performance after the implementation of the proposed strategy. The results obtained throughout the research demonstrate that the didactic strategy implemented was effective in improving the skills of 11th-grade students in the representation of chemical formulas.
