Abstract:
|
While constructing their
understanding in various domains of physics, students go through
transitional phases that may involve richly developed and consistently
used mental models. These transitional models are unique cognitive
structures composed of elements of both scientifically accepted and the
most commonly used initial alternative models and have been previously
referred to as hybrid models.1 The nature of hybrid models
complicates the process of determining students' mental models through
multiple-choice inventories. They may necessitate multiple questions to
determine a student's model in a single context. In the case of sound
propagation, three to four different questions (depending on the
context) are needed for this purpose. In addition, representing
students' usage of a hybrid model requires a separate dimension
associated with that particular hybrid model. We will show our solution
to the problems of addressing and representing hybrid models of sound
propagation using a classroom response system in real time. |
