Investigating approaches between scientific divulgation texts and chemistry teaching books

Abstract

This work aimed to promote the use of Scientific Dissemination Texts (SDT) by Basic Education Chemistry teachers, this work analyzed affinities between SDT published in Ciência Hoje Magazine, selected by Cantanhede (2012) and Sousa, Cantanhede e Cantanhede (2020) for the Chemical Bonds content, with discussions about this content present in the 6 Chemistry Textbooks, indicated by the National Textbook Program, for the 2018/2020 triennium. The affinity analysis was performed by the Wordle software, from the word cloud generation, which highlights terms that are more frequent in a set of words, and the IRaMuTeQ software, used for qualitative analysis of textual data, based on the factorial correspondence analysis and similitude analysis. The SDT Why doesn't water catch fire if it is made up of two combustible elements? (Edition 231, oct/2006) and How can sulfur bind to oxygen more than twice with both being divalent? (Edition 276, nov/2010), presented satisfactory affinity with the way the Chemical Bonds content is discussed in the investigated textbooks, considering the word clouds generated from these materials. The most prominent terms in textbooks were: hydrogen, atom, substance, element, molecule, and bond. SDTs use these terms to mention the meanings and explanations of chemical phenomena with the terms highlighted in the clouds. These relationships between SDT and Textbooks can represent an important parameter for the use of SDT in the classroom and, thus, support discussions in a contextualized way of chemical contents in Basic Education.
