| Abstract: | Our previous research has identified that in order to describe sound propagation students use two models that are fundamentally different: the wave model and the entity model.1 All other identified models are hybrid models that share some, but not all of the features of each of the fundamental models. We have constructed a multiple choice assessment to elicit the identified models. The assessment can be delivered in real time over a classroom response system to identify those mental models in a classroom setting. We will discuss the implications of hybrid models for instruction as well as for construction of the assessment that we developed. Finally, we will show results that we obtained using this assessment. |
