3. CLASSIFICAÇÃO DAS SUBSTÂNCIAS QUÍMICAS: UM CONCEITO POUCO EXPLORADO NA EDUCAÇÃO QUÍMICA
The classification of chemical substances is a concept little explored in Chemistry teaching literature and in Chemistry textbooks at higher and secondary levels. The aim of this paper is to discuss theoretically the importance and contributions of this concept for teaching and learning Chemistry. The History of Chemistry reveals that the chemical criteria f

5. A PROBLEMATIZAÇÃO DA ABORDAGEM TEMÁTICA NA FORMAÇÃO INICIAL DE PROFESSORES DE QUÍMICA
The thematic approach supported by Paulo Freire’s reference has been the object of study in the Teaching of Nature Sciences. In this work we analyzed which knowledge is explained by two undergraduate students about limits and potentialities related to the planning and development of a thematic approach promoted in the context of a supervised curricular int

6. 2021. Un año de incertidumbres para la Educación Matemática
This work describes a methodology to carry out the analysis of technological sectors, using information contained in patent documents. The use of this information by professors and students of chemistry courses and related areas is still little used. The consequence of this is the repetition of efforts to obtain some results of research and development. The

12. HÁ ALGO NOVO NO RECONHECIMENTO MOLECULAR APLICADO À QUÍMICA MEDICINAL?
In Medicinal Chemistry, the knowledge, the study and the understanding of the intermolecular interactions inherent to the molecular recognition of a ligand by its target bioreceptor are essential. This is because understanding these interactions, which define the molecular complementarity between the two, is the key to analyze critically structure-activity r
