P611: Representational competence in chemistry

Erin Rowan, Kereen Monteyne (Northern Kentucky University, USA)

Science disciplines use different types of representations to express its concepts. In chemistry, particulate representations are an important means to learn about the interactions of atoms and molecules. This research project examined representational competence in terms of how students interpret and connect the different types of representations used to describe chemical concepts. Several items were delivered on written course assessments, through online assessments, and in individual student interviews in chemistry courses for science majors. It was found that many students were able to make appropriate connections between representations but the different states of matter did influence student responses.
