“…One particular aspect of this sharing of chemistry knowledge that for many years has gained attention is embedded in the array of visual representations, such as molecular models, chemical equations, formulas, chemical structures, and chemical symbols, that have been both developed by the discipline of chemistry and its pedagogical counterpart (e.g., work done here; see Eilam & Gilbert, 2014;Gilbert & Treagust, 2009;Gilbert, Boulter, & Elmer, 2000;Gilbert, De Jong, Justi, Treagust, & van Driel, 2002;Kozma, 2003;Treagust, Chittleborough, & Mamiala, 2003;Uttal & O'Doherty, 2008;Wu & Shah, 2004). Yet, very little of this branch of research has looked at teachers' reasoning in relation to these visual representations (Ainsworth & Newton, 2014;Eilam, Poyas, & Hashimshoni, 2014), and in particular when using a perspective that has educational communication in the science disciplines being about all meaning-making systems in focus (Airey & Linder, 2009;Airey & Linder, 2017;Jaipal, 2010;Jewitt, Kress, Ogborn, & Tsatsarelis, 2001;Marquez, Izquierdo, & Espinet, 2006;Tang, Delgado, & Moje, 2014).…”
