The qualitative data collected through interviews was guided by the resources framework described by Hammer and Elby. We selected the resources framework instead of the conceptions framework to be consistent with current trends in educational research that avoid using deficit language such as "misconceptions". A resource is defined as the smallest unit of information or fine-grained knowledge element activated when solving 105 problems. Modir et al. expanded the definition of resource to "a manifold of knowledge pieces." Unlike the conceptions framework that categorizes information as an alternate or misconception, resources are not classified using correct or incorrect descriptions; instead, resources are viewed as productive or unproductive for a specific problem. What is finegrained? Rodriguez used the example "binds to the allosteric site of the enzyme" as a resource 110 despite consisting of several complex concepts. Because of the complexities of each of these concepts, some argue that the resources framework morphs into the conceptions framework; however, the key differences in the framework lie with the underlying assumptions. .
