2. ORBITALS IN GENERAL CHEMISTRY, PART III: CONSEQUENCES FOR TEACHING
In Part III of this series, we undertake a critique of the nature of application of orbitals to describe or to explain the structure and the binding within molecules and materials. Teaching orbitals in introductory chemistry presents five dilemmas that cannot be easily resolved. We thus conclude, based on mathematical realties, that orbitals are not essentia

4. PREPARAÇÃO DE HIDRAZONA E N-ACILIDRAZONA USANDO FÁRMACOS COMERCIAIS COMO REAGENTES: AULAS PRÁTICAS DE SÍNTESE DE COMPOSTOS BIOATIVOS
Several scientific works demonstrate the chemical and medicinal importance of hydrazone compounds. In this regard, the present paper proposes some practical classes of chemoinformatics and organic chemistry, using investigative and illustrative strategies, to teach the synthesis of a hydrazone and a N-acylhydrazone with proven biological activity. The motiva

5. PROPOSIÇÕES DIDÁTICAS PARA O FORMADOR QUÍMICO: A IMPORTÂNCIA DO TRIPLETE QUÍMICO, DA LINGUAGEM E DA EXPERIMENTAÇÃO INVESTIGATIVA NA FORMAÇÃO DOCENTE EM QUÍMICA
This theoretical paper proposes some pedagogical practices that may be applicable by chemical lecturers who teach in Chemistry teacher education courses. Those practices are based on three theoretical ideas: i) Johnstone’s triplet about the three levels of chemical knowledge (macroscopic, microscopic and symbolic) which imposes challenges due to the signif

7. CONSTRUÇÃO DA CURVA DE EQUILÍBRIO LÍQUIDO-VAPOR USANDO UMA EQUAÇÃO DE ESTADO CÚBICA: USO DO EXCEL NO ENSINO DE FÍSICO-QUÍMICA
Cubic equations of state are able to predict the liquid-vapour coexistence curve of volatile substances. However, this property is rarely used to teach Physical Chemistry because solving the resulting equations require numerical technics and many mathematical operations. In this report was shown how the interactive method for finding the root of an equation

8. COMUNICAÇÃO CIENTÍFICA NO ENSINO SUPERIOR DE QUÍMICA: UMA REVISÃO
The importance of teaching scientific communication skills in undergraduate chemistry courses is well recognized. This paper provides an overview of didactic activities in which students engage to improve these skills. The study was based on an extensive literature review performed on the Journal of Chemical Education and on the Journal of College Science Te

9. INNOVATIVE USE OF A TABLET DEVICE TO DELIVER INSTRUCTION IN UNDERGRADUATE CHEMISTRY LECTURES
This report describes a simple, inexpensive and highly effective instructional model based on the use of a tablet device to enable the real-time projection of the instructor's digitally handwritten annotations to teach chemistry in undergraduate courses. The projection of digital handwriting allows the instructor to build, present and adapt the class content

10. Nanoporous materials: pillared clays and regular silicas as an example of synthesis and their porosity characterization by X-ray diffraction
Because of their practical applications, porous materials attract the attention of undergraduate students in a way that can be used to teach techniques and concepts in various chemistry disciplines. Porous materials are studied in various chemistry disciplines, including inorganic, organic, and physical chemistry. In this work, the syntheses of a microporous

11. Contextualizando reações ácido-base de acordo com a teoria protônica de Brönsted-Lowry usando comprimidos de propranolol e nimesulida
This paper reports the use of alternative materials for teaching experimental chemistry. In this context, nimesulide and propranolol tablets were used to teach chemical concepts about acid-base reactions according to Brönsted-Lowry protonic Theory. Important topics of Organic, Analytical and Pharmaceutical Chemistry were discussed, such as purification by a
