“…Contudo, o que se observa é um trabalho puramente mecânico de execução de um roteiro sistematizado que se pauta na (re)produção de resultados efêmeros, sendo, portanto, necessário o uso de instrumentos que excedam os fundamentos técnicos da Química Verde, restritos aos seus princípios, à análise do processo e ao desempenho do material (Andraos & Sayed, 2007;Morales Galicia, 2011;Ribeiro & Machado, 2013;Vargas-Rodríguez, 2016), inserindo aspectos educacionais inerentes à formação docente.…”

Este trabalho busca analisar a inserção dos Princípios da Educação em Química Verde (EQV) nas propostas experimentais desenvolvidas pelos estudantes na disciplina de Experimentação na Educação Química do curso de Licenciatura em Química de uma Instituição de Ensino Superior (IES) federal localizada no estado de São Paulo. As propostas desenhadas pelos estudantes foram analisadas de acordo com os níveis de grau verde correspondentes aos Princípios da EQV. De acordo com as análises, verificou-se que as propostas caminharam de forma a contemplar níveis variáveis de grau verde, que, em geral, demonstraram um processo de aprendizagem em Química compatível à atuação responsável frente às dimensões tecnocientíficas, sociais, econômicas, geopolíticas e ambientais.

“…The ages of the students ranged from 20-22 years. Previously, a video was made with the simulation of an experiment (Vargas-Rodríguez et al, 2016). Also, an evaluation tool was designed, which was uploaded to the Google forms platform.…”

“…et al (2017). Also, it was analyzed what type of waste would be generated if the experiment had been carried out in the laboratory and the possible treatment of waste (Vargas-Rodríguez et al, 2016). From observations and experimental results, questions again arose, focused on solving the initial problem, for which another group collaborative activity was carried out to search for information through PBL cycles.…”

A problem-based online learning (PBe-L) teaching sequence was designed for calculating the shelf life (expiration date) of an on-site solution of refrigerated drug as part of activities of a Pharmaceutical Physical Chemistry course of Pharmacy major at FES Cuautitlán UNAM in Mexico. The teacher presents students the problem, a group collaborative activity is carried out to search for information in PBL cycles. Students are then shown a virtual experiment that includes experimental results. Another group collaborative activity is carried out for the search of information, for the procedural analysis of the results. Applying knowledge and understanding of the topics of chemical kinetics, temperature effect on the rate of chemical reactions and drug degradation reactions, etc., students solve the problem. Hake's factor was determined for the conceptual gain. A Likerttype satisfaction survey was conducted and compared to the results of a group that was applied to the PBL strategy in person. At the end of the sequence students achieved recognition, comprehension and application learnings and conceptual gain was high. Allowing an integration of its cognitive framework of kinetics topics.

“…Our research program is mainly focused on the implementation of green chemical procedures, mostly using non-conventional activating methods of reaction, such as nearinfrared and microwave irradiations, ultrasound, and tribochemistry to generate green processes [13][14][15][16][17][18][19][20]. It is important to highlight their corresponding greenness evaluation, by the employment of two metrics proposed by our group [21,22].…”

Green Chemistry Metrics, A Review

2022

View full text Add to dashboard Cite

Attending both the United Nations Decade of Education for Sustainable Development (2005–2014) and the United Nations 2030 Agenda for Sustainable Development, this review is presented, bearing in mind that green chemistry is essential to contribute to sustainability. This work has compiled all the information relating to green chemistry metrics, so that stakeholders can select an appropriate model, under the Green Chemistry Protocol, to evaluate how much green is a process. The review was organized considering the following convenient sections: the mass valuation, the recognition of the human health and environmental impact, metrics using computational programs (software and spreadsheets), and finally global metrics. This review was developed by consulting the principal databases, since the appearance of the first green chemistry textbook in 1998. A massive number of references were attained involving the keywords proposed below, with six languages observed, highlighted by the English language. It is important to emphasize that the 12 Principles of Green Chemistry are conceptual and offer little quantitative information. In addition, almost all the reported metric green propositions do not consider the 12 principles and few papers offer how to obtain an appropriate evaluation about the greenness of a research. In this sense, it is convenient to note that only in the Spanish literature are there two metrics that consider all the principles. Finally, to our knowledge, and after a deep search in the literature, it is the first review that covers the different features of green chemistry: mass, environment/human health. and in some cases, the use of computational programs.
