The procedures involved in separation include division or multiplication after properly grouping terms in an equation, moving terms (again, at times grouped) from one location on the page to another, or simply carrying out separation as a single act without showing any steps. We describe student use of these procedures in terms of Hammer\u2019s resources, showing that each of the previously listed procedures is its own \u201cpiece\u201d of a larger problem solving activity. Our data come from group examinations of students separating variables while solving an air resistance problem in an intermediate mechanics class. Through detailed analysis of four groups of students, we motivate that the mathematical procedures are resources and show the issues that students must resolve in order to successfully separate variables. We use this analysis to suggest ways in which new resources (such as separation) come to be.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mathematical actions as procedural resources: An example from the separation of variables Michael C.
