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. |
