Chemical reasoning takes many forms. The focus in this paper is on a reasoning process that facilitates using experimental evidence to make connections between macroscopic and submicroscopic domains, which we will refer to ascreating representation. It is a particular type of reasoning that has played a critical role in chemistry, enabling numerous scientific advancements and discoveries. Yet, the skill of creating representation is often not explicitly addressed in our introductory classrooms or laboratories. This paper outlines a process for creating and using representation that builds on other constructivist approaches but is framed in a new way to afford consistency across a continuum of novice learners to expert scientists. We illustrate how this approach is enacted in theCORElaboratory learning cycle (ChemicalObservationsRepresentationExperimentation), where supports are provided to help students generate ideas about representation. We also illustrate how lab reports provide opportunities for reflection, which can generate new ideas leading to revision of a representation. A comparison ofCOREwith the Atkin and Karplus learning cycle is also included to show how these different learning opportunities engage students in complementary cognitive processes to promote chemical reasoning skills.
