The unfortunate death of Andoni Garritz represents a formidable challenge for Chemical Education. In more than five decades of existence, it was almost a personal company, ended up being an institutional bulwark. Chemistry education before anything else, the journal of the Faculty of Chemistry of the National Autonomous University of Mexico.

The role of Argumentation on Conceptual Change and its relation with Lakatos epistemology

Rosária Justi, Marina Martins, Paula Cristina Cardoso Mendonça

The general aim of this paper is analyse the role of argumentation on students conceptual change process. In order to do so, we used Lakatos theoretical framework to base the analysis of data gathered in a modelling-based teaching of intermolecular interactions. Data were gathered from video recordings of all lessons involving such learning in a grade 11th class, the researchers field notes, and the copy of all written activities produced by students.

A green multicomponent reaction in the organic chemistry laboratory

Mariana Ingold, Gloria V. Lopez, Rosina Dapueto, Williams Porcal

In this century, chemists find themselves with a new challenge. They need to efficiently generate materials to maintain quality of life, but they have to do so reducing the negative effects on the environment and human health. Teaching green chemistry is fundamental to promote future scientists who can create safely and efficiently non-toxic products and processes in the way for a sustainable future. The use of a multicomponent reaction, as the Passerini reaction, for the generation of new molecules as drug candidates, is describedhere as an experiment for undergraduate organic chemistry laboratory. It is a fast, efficient andsimple process which generates a complex product using simple reactants in one step. Differentmetrics were determined in order to measure how environmentally friendly this reaction is, inthe conditions tested. The student will be able to discuss: green chemistry, development ofbioactive molecules, diversity-oriented synthesis, multicomponent reactions, and chemistry inaqueous solution.
