Metodologias lúdicas no ensino de química inorgânica: palavras cruzadas para o estudo dos compostos de coordenação

Abstract

This study is focused on the development of a didactic proposal based on crossword puzzles, aimed at teaching coordination compounds, an essential topic in Inorganic Chemistry. The main objective was to develop and structure a set of crossword puzzles, categorized into three levels of difficulty, addressing topics such as an introduction to coordination compounds, nomenclature, and isomerism. The proposal covers fundamental concepts, including the definition of basic terms (ligand, Lewis acid, Lewis base, and central atom), the classification of ligands, and the types of isomerism (substitutional, spatial, cis-trans, mer-fac, and enantiomers). The literature review conducted revealed that the learning of Inorganic Chemistry presents recurring obstacles related to the abstraction of concepts, specific terminologies, and the lack of effective strategies for content consolidation. In this context, the use of playful methodologies, such as educational games, emerges as a promising strategy to enhance motivation, autonomy, and meaningful learning. Among the playful resources, crossword puzzles stand out for promoting the active retrieval of information, the retention of technical vocabulary, and the differentiation between similar concepts, in addition to serving as a formative assessment tool. The crossword puzzles were designed to aid knowledge, starting with simple concepts. The material developed aims to provide a playful didactic resource that promotes logical reasoning, memorization, and understanding of concepts. It is concluded that crosswords, when intentionally and critically planned, represent an effective resource to enhance the teaching of Inorganic Chemistry, promoting greater student engagement and consolidating essential knowledge in a playful and inclusive manner
