Content, design, and representation in chemistry

Creating Representation in Support of Chemical Reasoning to Connect Macroscopic and Submicroscopic Domains of Knowledge

“…that one sees, which are infused together to create representation. The idea that the structure depicted in artwork is important in science has also been expressed “because scientific representation is inherently contextual” . Schnotz and Bannert describe a semantic process for turning a drawing into more than just perception.…”

“…The instructions for how to use representation have been discussed in terms of what we see: a “stick model is inexplicitly non-committal with regards to possessing or not possessing atomic nuclei. The model does not preclude the possibility of representing the nuclei; chemists merely suppress them.” The use of models or how suppression may occur during the process of modeling is important because it suggests a central role for the individual and raises the question, what source of information is being used to decide what to include and what to ignore? These ideas are critical especially for students who are asked to process the meaning of a representation with information that may not be accessible or understood by them.…”

“…Fisher describes how representation in chemistry involves interplay between content and design. 59 "Content" refers to the properties attributed to a representational target, while "design" is the marks, lines, etc. that one sees, which are infused together to create representation.…”

“…The idea that the structure depicted in artwork is important in science has also been expressed "because scientific representation is inherently contextual". 59 Schnotz and Bannert describe a semantic process for turning a drawing into more than just perception. In this process, a propositional representation is used in model construction, thereby forming a mental model using analogical reasoning.…”

Acerca del estatuto ontológico de los fonones

“…Este marco lingüístico o conceptual puede ser entendido en términos generales o concretos. Algunos autores (Giere 2006, Fischer 2017 de hecho circunscriben el marco de referencia a partir del cual observamos el mundo a los modelos y a las técnicas experimentales especificas que se utilizan. Otros autores (Lombardi y Pérez Ransanz 2012), en cambio, ponen el foco en ciertos conceptos generales y abstractos como ser la noción de individuo, la noción de espacio, la noción de tiempo o la concepción determinista o indeterminista que se tenga del mundo.…”
